Cryptocurrencies and blockchain technology have evolved significantly since the advent of Bitcoin in 2009. The technology underlying cryptocurrencies and blockchain has grown and matured, giving rise to various types of blockchain platforms, including layer-1 platforms.
A crucial component of the blockchain ecosystem is layer-1 platforms, which serve as the foundation of the technology. These platforms are responsible for providing the fundamental functionalities that enable blockchain-based systems to function, allowing for the creation and operation of decentralized applications (dApps).
As the base layer of the blockchain stack, layer-1 platforms play a vital role in the infrastructure of blockchain technology. They are responsible for creating and validating blocks, maintaining the consensus mechanism, and managing transactions. These functionalities are crucial for the proper operation of decentralized applications, as they ensure that the data stored on the blockchain is accurate and secure.
Layer-1 platforms differ from other types of blockchain platforms, such as layer-2 scaling solutions or blockchain interoperability protocols. While layer-2 solutions aim to improve the scalability and efficiency of the existing blockchain infrastructure, layer-1 platforms focus on building a robust and scalable blockchain infrastructure from scratch. Layer-1 platforms provide a complete and self-sufficient ecosystem for decentralized applications to operate, without the need for external dependencies.
Scalability has been a major concern for blockchain platforms, especially for earlier platforms such as Bitcoin and Ethereum. These platforms have faced challenges with high transaction fees and slow transaction processing times due to their limited transaction throughput. However, layer-1 platforms have emerged as a solution to this scalability problem.
Layer-1 platforms, such as Solana and Cardano, use advanced consensus mechanisms like Proof of Stake (PoS) or Delegated Proof of Stake (DPoS) to achieve higher transaction throughput and scalability. PoS allows faster transaction processing times while reducing energy consumption, making it a more environmentally friendly alternative to older consensus mechanisms like Proof of Work (PoW). DPoS involves a smaller group of validators, who are elected by token holders to validate transactions, leading to faster transaction processing times and a more efficient network.
By adopting these advanced consensus mechanisms, layer-1 platforms can handle a larger volume of transactions and achieve higher scalability while maintaining decentralization. This has made them more appealing to developers who require a more efficient and scalable blockchain infrastructure to build decentralized applications.
Another advantage of layer-1 platforms is their ability to offer greater flexibility and control over the blockchain infrastructure. This is because they are not bound by the limitations of existing blockchain infrastructure and can create a completely self-sufficient ecosystem for decentralized applications to operate. This allows developers to create more complex and sophisticated, decentralized applications with greater ease and flexibility.
Although most of the privacy blockchains don’t include in the definition of layer-1 platforms in today’s modern definition, I decided to take a look at them before going further.
Layer-1 platforms have become increasingly popular due to their ability to provide enhanced security and privacy features that were previously unavailable on earlier blockchain platforms. Two examples of such platforms are Zcash and Monero.
These platforms utilize advanced cryptography to provide enhanced privacy and anonymity features that can protect users from data breaches, identity theft, and other types of cyberattacks. These features make layer-1 platforms ideal for use cases that require higher levels of security and privacy, such as financial transactions and sensitive data management.
Zcash, for instance, provides a feature called “shielded transactions,” which enables users to protect their transaction data from being viewed by third parties. Monero, on the other hand, utilizes ring signatures, which enable users to mask their transaction information by combining it with other users' information in a ring structure.
The use of advanced cryptography on layer-1 platforms ensures that transactions and data are securely stored and transmitted. This is particularly important for organizations and individuals who require the highest levels of security and privacy to protect their sensitive data from unauthorized access.
In addition, layer-1 platforms also offer greater control over user data, as users can choose whether to reveal their identities or not. This allows users to participate in decentralized applications and transactions without compromising their personal information.
The growth and adoption of the blockchain ecosystem largely depend on the success of layer-1 platforms. With the development and deployment of more decentralized applications on the blockchain, the need for a robust and scalable infrastructure becomes increasingly vital. Layer-1 platforms play a crucial role in providing the foundation for building decentralized applications that can meet the demands of a global user base.
The importance of layer-1 platforms lies in their ability to provide core functionalities that allow for the creation and validation of blocks, maintenance of the consensus mechanism, and management of transactions. These platforms offer a complete and self-sufficient ecosystem for decentralized applications to operate without external dependencies.
As the adoption of blockchain technology continues to grow, layer-1 platforms such as Ethereum, Solana, and Cardano have emerged as prominent players in the market. They provide advanced features such as enhanced security, privacy, and scalability to meet the requirements of different use cases.
One of these Layer-1 platforms is Cardano. Cardano is a pioneering decentralized third-generation blockchain platform and home to the ADA cryptocurrency. It is the first blockchain platform to be developed with a research-first-driven approach and a scientific philosophy. This makes it a revolutionary system, designed to meet the needs of a rapidly changing world.
The Cardano platform is built on a unique architecture that allows for scalability and interoperability. This means that it can be used as a platform for various applications and services, from finance to health and beyond.
The Cardano platform also features several technologies, such as smart contracts and sidechains, that make it possible for developers to create powerful decentralized applications. This makes it a great choice for businesses looking to build secure and reliable applications.
Finally, Cardano is open source, meaning it is free and accessible to anyone, regardless of their technical background. This makes it an ideal platform for those looking to start with blockchain technology.
The Cardano platform has been developed with sustainability and scalability in mind. It has been designed from scratch by top engineers and academic experts in the fields of blockchain and cryptography, with a strong focus on security, transparency, and inclusivity. By leveraging the power of a functional programming language, like Haskell, and utilizing formal and executable specifications, property-based testing, and simulation testing, the Cardano platform can provide a safe and secure infrastructure for financial and social applications.
Cardano’s primary goal is to provide reliable, secure financial services to those who currently don’t have access to such services. It seeks to be more advanced than any other protocol that has been developed and serves as a stable and secure platform for the development of enterprise-level dApps. To aid in this effort, Cardano will be implementing a democratic governance system that is designed to evolve and fund itself sustainably through a treasury system.
The Cardano platform also provides a secure and reliable platform for the development of enterprise-level dApps. It has a development environment that supports multiple languages including Haskell, Rust, and C++, allowing developers to create custom dApps and tokens. It also has a built-in wallet and supports a wide range of cryptocurrencies and tokens.
In addition to its development environment and consensus algorithm, the Cardano platform also features a secure, open-source wallet. This wallet provides an easy-to-use interface for securely managing funds and also supports a wide range of cryptocurrencies and tokens. It also features a built-in security system that helps protect users against malicious attacks.
The first generation of blockchains, such as Bitcoin, ushered in a new era of secure cryptocurrency transfer. They have been a major cornerstone of the blockchain revolution, as they have allowed users to transfer funds without any type of middleman or other third-party interference. This was a major development in the financial world, as it allowed users to have complete control over their funds, and ensured that all transactions were secure and immutable.
In addition to this, the first generation of blockchains also provided users with a distributed ledger system. This means that all transactions are recorded on a public ledger, allowing users to view and verify the accuracy of all transactions. This provides a level of transparency that was previously not possible with traditional financial systems.
However, the first generation of blockchains had several limitations. They were limited in terms of their functionalities, as they could not handle complex smart contracts and decentralized applications (DApps). This limited their usefulness and prevented them from being used for more than just cryptocurrency transfers.
Enter the second generation of blockchains, such as Ethereum. This new generation of blockchains addressed many of the limitations of the first generation and provided users with a platform for writing and executing smart contracts and developing decentralized applications. This allowed developers to create a variety of applications and services, ranging from financial services to gaming and social media platforms.
On the other hand, the second generation of blockchains often faces issues in terms of scalability. This means that the blockchain can only process a limited number of transactions at a given time, which can cause delays and network congestion. As a result, the blockchain may not be able to keep up with the demand of users and applications, which can lead to decreased performance and efficiency.
Despite these issues, the second generation of blockchains has been a major step forward in the development of blockchain technology. It has opened up a world of possibilities, allowing users to create a variety of applications and services on the blockchain. This has the potential to revolutionize many industries and bring about a new wave of innovation.
Cardano is a third-generation blockchain technology platform, conceived to meet the needs of users and provide them with the highest level of security, scalability, and functionality. Unlike prior generations of blockchains, Cardano is designed to combine the advantages of both and evolve to meet the changing needs of its users.
To meet these needs, Cardano has taken a unique approach to blockchain security, scalability, and functionality. In terms of security, Cardano uses a unique consensus mechanism called Ouroboros, which is designed to ensure the security of the network. This mechanism is based on a proof-of-stake algorithm, which is designed to protect the network from malicious actors.
In terms of scalability, Cardano is designed to handle large amounts of data, transactions, and network bandwidth. This is achieved through a sophisticated system of sidechains, which allows for the efficient processing of large amounts of data without compromising the security of the network.
In terms of functionality, Cardano provides a wide range of services and features to its users, including smart contracts and decentralized applications. This allows users to create and execute contracts and applications without the need for a central authority.
Finally, Cardano is designed to be interoperable with other blockchains and financial institutions. This allows users to take advantage of the best features of multiple blockchains and financial institutions, increasing the flexibility and scalability of the platform.
To address these needs, Cardano focuses on core concepts, such as:
Scalability: Cardano places great importance on scalability, as it ensures that the network can process more transactions as user demand increases. This is crucial to prevent delays or network congestion during times of high traffic. Additionally, Cardano is implementing several techniques to enhance its scalability, such as data compression to reduce the amount of data transferred during transactions.
Moreover, Cardano is working on introducing Hydra, which is expected to provide additional scalability benefits. It will allow for the creation of multiple side chains, which will help to further distribute the network's transaction processing load. This will enable Cardano to handle significantly higher transaction volumes without compromising on speed or security.
Interoperability: Interoperability is an essential feature for blockchain platforms, as it allows users to interact with multiple currencies across various blockchains. Cardano is being developed with interoperability in mind to create a multi-functional environment for financial, business, or commercial operations. In addition to supporting cross-chain transfers, Cardano will also support multiple token types and commonly used smart contract languages.
Furthermore, Cardano aims to ensure interoperability with centralized banking entities, which is crucial for granting legitimacy and convenience of use to the platform. This will enable users to easily transfer funds between traditional banking systems and the blockchain, opening up new possibilities for businesses and individuals.
Sustainability: To ensure a self-sustaining proof-of-stake blockchain, Cardano is designed to enable the community to maintain its development in a truly decentralized manner. The treasury system is controlled by the community, and potential sources for its constant refilling include newly-minted coins held back as funding, a percentage of stake pool rewards, and transaction fees. This approach enables growth and maturity to be driven by the community through their participation, proposals, and implementation of system improvements, ensuring the sustainability of the platform.
Academic research: Cardano's development is based on academic research using formal methods like mathematical specifications, proofs, and property-based tests, which provides users with greater confidence in managing digital funds. This approach ensures the high assurance of software systems and core components of the Cardano platform, enabling strong guarantees of functional correctness. The development of Cardano is transparent as all research and technical specifications are publicly available, and all development activities are published online. This openness provides the community with a clear understanding of the platform's capabilities, how it functions, and its potential limitations, allowing for a collaborative approach to its ongoing development.
System design: Cardano's system is designed using Haskell, a functional programming language that promotes creating a system using pure functions that can be tested in isolation. Haskell also offers advanced features that enable Cardano to use various powerful methods for ensuring the correctness of its code. Cardano is built on formal and executable specifications, extensive property-based testing, and running tests in simulation. All these measures contribute to a more secure and robust system that is better able to ensure the safety and security of users' funds.
Security: The security of Cardano is ensured through the use of Ouroboros, a proof-of-stake protocol that provides strict security guarantees. The development of Ouroboros was based on several peer-reviewed papers that were presented at prestigious cybersecurity and cryptography conferences and published in respected academic publications. Through this rigorous approach, Cardano can ensure that the security of the network is maintained at all times, protecting users' digital assets and transactions from potential threats.
Energy efficiency: Cardano has a much more energy-efficient approach compared to other blockchain platforms like Bitcoin. This is because Cardano uses a proof-of-stake consensus algorithm, which requires much less computational power than the proof-of-work algorithm used by Bitcoin. In proof-of-work systems, computers compete to solve complex mathematical problems to validate transactions and add them to the blockchain, which consumes a lot of energy. On the other hand, in proof-of-stake systems like Cardano, validators are chosen based on the amount of cryptocurrency they hold, and they are responsible for verifying transactions and creating new blocks. Since this process is less energy-intensive, Cardano has a much smaller carbon footprint compared to Bitcoin. This energy efficiency is crucial for the sustainability of the blockchain in the long term, as it helps to reduce the environmental impact of the platform.
A hard fork is a significant alteration in a blockchain's protocol, resulting in changes to how the blocks are processed, verified, or interpreted. This type of change can be necessary to implement new features or to fix critical vulnerabilities in the blockchain's security. Hard forks can also result in the creation of a new cryptocurrency, as the forked chain may have different rules, tokens, and values from the original chain. However, hard forks can also lead to the fragmentation of the community and network effect, as different groups may disagree on the direction and implementation of the protocol changes.
One of the most famous examples of a hard fork was the Bitcoin hard fork that occurred in August 2017. Bitcoin Cash was created as a result of the hard fork, and it aimed to improve upon the original Bitcoin protocol by increasing the block size limit, which would allow for faster and more efficient transactions.
Another example of a hard fork is the Ethereum hard fork that occurred in 2016. The DAO (Decentralized Autonomous Organization) was a smart contract on the Ethereum blockchain that aimed to create a decentralized venture capital fund. However, a vulnerability was exploited, and funds were drained from the DAO. In response, the Ethereum community conducted a hard fork, which resulted in the creation of Ethereum and Ethereum Classic.
Hard forks can be a contentious issue within the blockchain community, with some arguing that they go against the decentralized nature of the technology. However, they can also be a necessary step for improving the security and efficiency of the blockchain.
It is worth noting that not all blockchain upgrades require a hard fork. In some cases, soft forks can be used instead. Soft forks are backwards-compatible upgrades that do not require a change to the blockchain's protocol. This means that they are less disruptive and have less potential for causing a chain split.
Ultimately, the decision to conduct a hard fork or a soft fork will depend on the specific circumstances and the goals of the blockchain developers. It is important for the community to come to a consensus on the need for a hard fork and to communicate the changes to users to minimize any potential disruption.
One of the major milestones in the development of the Cardano blockchain was the transition from a federated model, called Byron, to a decentralized one, called Shelley (you can read about these phases in the Roadmap section). This transition was achieved through a hard fork, which is a process of changing the protocol rules of a blockchain. However, unlike most hard forks, which create a radical break from the previous version and erase its history, the Cardano hard fork was designed to be smooth and seamless. The chain did not undergo a drastic change, but rather preserved the history of the Byron blocks and added new Shelley blocks after a period of adjustment. This way, there was no need to start from scratch and lose the record of previous activities on the blockchain.
Hard Fork Combinator
A technical term known as a combinator is used to describe the combination of certain processes or things. In the context of Cardano, a hard fork combinator is utilized to combine protocols, allowing for a seamless transition from Byron to Shelley without any system interruption or restart. This ensures that the Byron and Shelley ledgers appear as a single ledger, providing a smooth and uninterrupted experience for users.
The hard fork combinator is designed to enable the combination of multiple protocols without requiring significant adjustments. Currently, the Cardano chain combines Byron and Shelley blocks, and future transitions will also combine Goguen, Basho, and Voltaire blocks as a single property. This combinator simplifies the previous Byron-to-Shelley evolution, making it easier to transition from Shelley to Goguen and beyond.
One of the key benefits of the hard fork combinator is that it allows nodes to update gradually, rather than requiring all nodes to update simultaneously. This means that some nodes can run Byron blocks while others run Shelley blocks, making the transition smoother and more efficient.
By utilizing the hard fork combinator, Cardano is able to combine multiple protocols seamlessly, providing a more streamlined experience for users. As Cardano continues to evolve and transition to new protocols, the hard fork combinator will play a crucial role in ensuring a smooth and uninterrupted experience for all users.
Moving from Byron Ouroboros Classic to Shelley Ouroboros Praos
Cardano's Byron mainnet was built on the Ouroboros Classic consensus protocol. Ouroboros Classic was later replaced by the new Ouroboros Praos consensus protocol in the current development era, known as Cardano Shelley mainnet (you can read about Cardano’s consensus mechanism in the Ouroboros chapter). This new protocol offers extended capabilities and supports the staking process with monetary rewards for ADA holders and stake pool owners.
To ensure a smooth transition to the new protocol without any disruptions to the system, Cardano needed to update the code to support the new protocol's conditions. However, updating the code in a single update could have caused a range of complexities. To avoid this, Cardano decided to take a two-stage approach, using the Ouroboros Byzantine Fault Tolerance (BFT) protocol as an intermediary.
The shift from Ouroboros Classic to BFT, which occurred on February 20, 2020, was the only traditional hard fork within the Cardano blockchain. This forking event restarted the Byron mainnet to run the BFT protocol, enabling a smoother transition to Ouroboros Praos without any further chain interruptions. The BFT protocol was carefully designed to ensure that the blockchain history remained unchanged, and the blockchain appeared as a single entity.
By using the BFT protocol as an intermediary, Cardano was able to ensure that the transition to the new protocol was orderly and without any diversions in the system. This approach allowed for a more seamless transition to the new protocol, which offers extended capabilities and supports the staking process with monetary rewards for ADA holders and stake pool owners.
Overall, Cardano's approach to transitioning to the new protocol demonstrates its commitment to ensuring a smooth and uninterrupted experience for users. By carefully designing the BFT protocol as an intermediary, Cardano was able to avoid any disruptions to the system and ensure that the blockchain history remained unchanged. As Cardano continues to evolve and transition to new protocols, it will undoubtedly continue to prioritize a smooth and seamless experience for all users.
Token Locking: Shelly Protocol Upgrade
Cardano's Shelley protocol is set to introduce a new feature called token locking, which will enable various smart contract use cases, including creating and transacting with multi-asset tokens and supporting the Voltaire voting mechanism. Token locking involves reserving a certain amount of assets and committing not to dispose of them for a specified period of time. This feature will be enabled in the Allegra upgrade and will allow for the recording of specific tokens being used for a certain purpose during the Mary upgrade.
The token can represent an item that is accounted for by the blockchain ledger, including ADA, but will soon include other custom token types. With the introduction of token locking, Cardano is taking another step towards enabling a more robust and versatile blockchain ecosystem. This feature allows for the creation and transacting of multi-asset tokens, which can represent a wide range of assets, including stocks, bonds, and real estate. Additionally, token locking will support the Voltaire voting mechanism, which will enable ADA holders to vote on important decisions related to the Cardano ecosystem.
You can list some of this feature’s use cases below:
Contractual agreement: When entering into a contractual agreement, such as selling a property, it is crucial to ensure that the property is not sold to anyone else but the person who pays the money. Token locking can represent the property, while the 'promise' is the actual token locking. This feature enables a more secure and reliable way to ensure that contractual agreements are upheld and that assets are not sold to unauthorized parties.
By using token locking, Cardano is taking another step towards enabling a more robust and versatile blockchain ecosystem. This feature can be used to represent a wide range of assets, including real estate, stocks, and bonds. With the ability to represent assets in this way, contractual agreements can be more easily enforced, and the risk of fraud or unauthorized sales can be minimized.
Overall, token locking is a significant development for Cardano, as it enables a more secure and reliable way to ensure that contractual agreements are upheld and that assets are not sold to unauthorized parties. With the ability to represent a wide range of assets, token locking is poised to play a crucial role in the growth and development of the Cardano blockchain ecosystem.
Vote registry: The Voltaire voting mechanism within Cardano will utilize token locking to enable users to lock a certain amount of their tokens to represent their voting rights. ADA holders who participate in the voting process will be required to 'lock' their tokens, which will represent their voting rights according to the stake they hold. This feature will eliminate the risks associated with scenarios such as double-counting votes, allocating more votes than possible, contradictory votes, or vote duplication.
By using token locking within the Voltaire voting mechanism, Cardano is taking another step towards enabling a more secure and reliable way to conduct voting processes. This feature ensures that each vote is accurately represented and that the voting process is fair and transparent. With the ability to represent voting rights in this way, Cardano is well-positioned to continue its growth and development as a leading blockchain platform.
Multi-asset tokens: Cardano is set to provide support for multi-asset tokens, which will enable the creation and use of multiple custom token types, in addition to ADA. With the introduction of multi-asset tokens, Cardano is taking another step towards enabling a more versatile and robust blockchain ecosystem. Token locking allows ADA tokens to be 'locked' to create another custom asset of equivalent value.
By using token locking to create custom assets, Cardano is enabling a more secure and reliable way to represent a wide range of assets on the blockchain. This feature will enable the creation of custom assets that can represent a wide range of assets, including stocks, bonds, and real estate. With the ability to represent assets in this way, Cardano is well-positioned to continue its growth and development as a leading blockchain platform.
Mary: multi-asset support
The Mary upgrade, implemented in March 2021, introduced native tokens and multi-asset support on the Cardano blockchain. This upgrade allows users to create uniquely defined (custom) tokens and carry out transactions with them directly on the Cardano blockchain.
With the introduction of native tokens and multi-asset support, the accounting infrastructure of the Cardano blockchain can now process transactions that simultaneously carry several asset types, including ADA. This native support grants distinct advantages for developers, as there is no need to create smart contracts to handle custom token creation or transactions. Instead, the accounting ledger tracks the ownership and transfer of assets, removing extra complexity and potential for manual errors, while ensuring significant cost efficiency.
Developers, businesses, and applications can create general-purpose (fungible) or specialized (non-fungible) tokens to achieve commercial or business objectives. These tokens can be used for a wide range of purposes, including the creation of custom payment tokens or rewards for decentralized applications, stablecoins pegged to other currencies, or unique assets that represent intellectual property. All these assets can then be traded, exchanged, or used as payment for products or services.
Overall, the Mary upgrade is a significant development for Cardano, as it enables a more versatile and robust blockchain ecosystem. With the ability to create custom tokens and carry out transactions with them directly on the blockchain, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. By removing extra complexity and the potential for manual errors, while ensuring significant cost efficiency, Cardano is taking another step towards creating a more transparent and trustworthy blockchain ecosystem.
Alonzo: smart contract support
The Alonzo protocol upgrade, implemented in September 2021 as part of the Goguen development theme, builds on top of transaction metadata, token locking, and native asset functionality to enable smart contract development on the Cardano blockchain.
This upgrade introduces a versatile platform that opens up opportunities for businesses and developers by allowing the creation of smart contracts and decentralized applications (DApps) for decentralized finance (DeFi). With the ability to create smart contracts and DApps, Cardano is taking another step towards enabling a more robust and versatile blockchain ecosystem.
To enable smart contract development, the Alonzo upgrade adds the necessary tools and infrastructure using the Plutus Platform. Applying a rigorous approach based on formal methods and verification, Alonzo extends the basic multi-signature scripting language (multisig) used in Cardano Shelley. Multisig is being upgraded to the Plutus Core language for more powerful and secure scripting options. For this, Alonzo implements the extended unspent transaction output (EUTXO) accounting model.
The Extended Unspent Transaction Output (EUTXO) model is a unique approach to blockchain architecture that allows for greater flexibility and security in the execution of smart contracts.
In traditional blockchain models, transactions are executed by updating the current state of the blockchain. This means that each transaction must be validated against the current state of the blockchain, which can be a time-consuming and resource-intensive process.
The EUTXO model, on the other hand, uses a system of “outputs” and “inputs” to execute transactions. Each output represents a specific amount of cryptocurrency that is locked to a specific script, while each input represents a reference to a previous output that has been unlocked by a specific script.
When a new transaction is created, it must reference one or more previous outputs as inputs, and it must also specify one or more new outputs that will be created as a result of the transaction. The script associated with each output determines the conditions under which the output can be spent in a future transaction.
This approach has several advantages over traditional blockchain models. First, it allows for greater flexibility in the execution of smart contracts, as each output can have its own unique script that specifies the conditions under which it can be spent. Second, it provides greater security, as each output can only be spent once and any attempt to spend it again will be rejected by the network.
Overall, the Alonzo protocol upgrade is a significant development for Cardano, as it enables a more versatile and robust blockchain ecosystem. With the ability to create smart contracts and DApps, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. By implementing the EUTXO accounting model and upgrading multisig to the Plutus Core language, Cardano is taking another step towards creating a more transparent and trustworthy blockchain ecosystem.
Vasil: Plutus 2.0 and the debut of pipelining
The Vasil protocol upgrade, named after the late Bulgarian mathematician and prominent Cardano community member Vasil Dabov, was set to be implemented in June 2022, but with a delay in launch, it was implemented in September 2022. This upgrade introduces five key mechanisms to improve the blockchain's performance: CIP-31 (Reference Inputs), CIP-32 (Inline Datums), CIP-33 (Reference Scripts), CIP-40 (Collateral Outputs), and diffusion pipelining.
These improvements boost Cardano's usability and scalability by increasing the block size limit to fit more transactions per block. With the ability to fit more transactions per block, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. Additionally, developers will have a better experience while building on Cardano, as Vasil will greatly reduce the complexity of creating and deploying DApps on Cardano.
One of the main focuses of the Vasil upgrade is Plutus scripts. These scripts will live persistently on-chain, so they can be referenced when needed, which will improve efficiency. With this feature, there will no longer be a need to include the script in the transaction attempting to spend its outputs. This improvement will enable more efficient and reliable smart contract execution on the Cardano blockchain.
Overall, the Vasil protocol upgrade is a significant development for Cardano, as it enables a more versatile and robust blockchain ecosystem. With the ability to fit more transactions per block and reduce the complexity of creating and deploying DApps on Cardano, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. By improving Plutus scripts and enabling more efficient and reliable smart contract execution, Cardano is taking another step towards creating a more transparent and trustworthy blockchain ecosystem.
We mentioned the EUTXO, or the Extended UTXO model, before. It is good to discuss what this model is and how it works best for Cardano.
The Extended Unspent Transaction Output (EUTXO) model is a unique accounting model utilized by Cardano, which is an Unspent Transaction Output (UTXO)-based blockchain like Bitcoin. Unlike other account-based blockchains such as Ethereum, Cardano's ledger operates on a different accounting model. The EUTXO model is introduced by the Alonzo upgrade to support multi-assets and smart contracts, making it an innovative solution for Cardano.
Overview of the UTXO Model
The Unspent Transaction Output (UTXO) model operates on the principle that a transaction has inputs and outputs. The inputs are unspent outputs from previous transactions, and assets are stored on the ledger in unspent outputs rather than in accounts. In essence, a transaction is an action that unlocks previous outputs and creates new ones. This approach ensures that the ledger remains secure and immutable, as each transaction is verified and validated by the network.
Transaction Output
The Unspent Transaction Output (UTXO) model is a unique approach to blockchain accounting that operates on the principle that a transaction output comprises an address and a value. The address can be thought of as a lock, and the signature that corresponds to the address is the key to unlock the output. Once unlocked, an output can be used as input for a new transaction.
In the UTXO model, new transactions spend outputs from previous transactions and create new outputs that can be consumed by future transactions. Each UTXO can only be consumed once and as a whole. This means that each output can be spent by exactly one input, and one input only. This approach ensures that the ledger remains secure and immutable, as each transaction is verified and validated by the network.
The UTXO model differs from the account-based model used by other blockchains such as Ethereum. By storing assets in unspent outputs rather than accounts, the UTXO model provides a more secure and efficient way of managing transactions. The UTXO model also enables the implementation of smart contracts and multi-assets, making it a versatile solution for blockchain networks like Cardano.
The users' wallets manage the UTXOs and initiate transactions involving the UTXOs owned by the user. Each blockchain node maintains a record of the subset of all UTXOs at all times, known as the UTXO set. The UTXO set is stored in the data directory of every node and is technically referred to as the chainstate.
When a new block is added to the chain, the chainstate is updated accordingly. This new block contains the latest transactions, including a record of spent UTXOs and new ones created since the chainstate was last updated. Every node maintains an exact copy of the chainstate, ensuring that the ledger remains secure and immutable.
Extended UTXO Model
The Extended Unspent Transaction Output (EUTXO) model is an innovative solution that extends the Unspent Transaction Output (UTXO) model in two significant ways.
Firstly, the EUTXO model generalizes the concept of 'address' by using the lock-and-key analogy. Unlike the UTXO model, which restricts locks to public keys and keys to signatures, addresses in the EUTXO model can contain arbitrary logic in the form of scripts. When a node validates a transaction, it determines whether the transaction is allowed to use a certain output as an input. The transaction will look up the script provided by the output's address and will execute the script if the transaction can use the output as an input. This approach provides greater flexibility and security, as it allows for more complex and customizable scripts to be used in transactions.
Secondly, the EUTXO model allows outputs to carry (almost) arbitrary data in addition to an address and value. This makes scripts much more powerful by allowing them to carry state information. This state information can be used to implement smart contracts and other complex applications on the blockchain. By allowing outputs to carry additional data, the EUTXO model provides a more versatile and efficient way of managing transactions.
The EUTXO model is a significant improvement over the UTXO model, as it provides greater flexibility and security while maintaining the efficiency and immutability of the blockchain. The EUTXO model is introduced by the Alonzo upgrade to support multi-assets and smart contracts, making it a valuable addition to blockchain networks like Cardano.
Furthermore, EUTXO allows output addresses to contain complex logic to decide which transactions can unlock them and adds custom data to all outputs.
When validating an address in the EUTXO model, the script will access the data being carried by the output, the transaction is validated, and some additional pieces of data called redeemers, which the transaction provides for every input. By looking up all this information, the script has enough context to give a 'yes' or 'no' answer in what can be highly complex situations and use cases. This approach provides greater flexibility and security, as it allows for more complex and customizable scripts to be used in transactions.
The EUTXO model enables arbitrary logic in the form of scripts, which inspect the transaction and the data to decide whether the transaction is allowed to use an input or not. This approach provides a more secure and efficient way of managing transactions, as each transaction is verified and validated by the network, making it more secure and less prone to errors.
The EUTXO model is introduced by the Alonzo upgrade to support multi-assets and smart contracts, making it a valuable addition to blockchain networks like Cardano. By allowing for more complex and customizable scripts to be used in transactions, the EUTXO model provides greater flexibility and security while maintaining the efficiency and immutability of the blockchain.
The Unspent Transaction Output (UTXO) model used by Cardano is fundamentally different from the account-based model used by some existing smart-contract-enabled blockchains. As a result, the design patterns that work for DApps on account-based blockchains do not translate directly to Cardano. New design patterns are needed because the underlying representation of the data is different.
The Extended Unspent Transaction Output (EUTXO) model inherits the per-branches design of the UTXO (Bitcoin) model, where one branch is by definition a sequence of transactions that requires a sequence of validations. To split the logic across different branches and enforce more parallelism, it is essential to build DApps and other solutions using multiple UTXOs. This approach provides benefits in terms of scaling, just like developing Bitcoin services prerequisites splitting one wallet into sub-wallets.
By using multiple UTXOs, developers can split the logic across different branches and enforce more parallelism, which is essential for building DApps and other solutions on the Cardano blockchain. This approach provides benefits in terms of scaling, making it a valuable addition to blockchain networks like Cardano.
Advantages of EUTXO
Cardano's Extended Unspent Transaction Output (EUTXO) model is a significant improvement over other accounting models, providing a secure and versatile environment to process multiple operations without system failures. This model offers better scalability and privacy, as well as more simplified transaction logic, as each UTXO can only be consumed once and as a whole, which makes transaction verification much simpler.
The EUTXO model offers unique advantages over other accounting models. The success or failure of transaction validation depends only on the transaction itself and its inputs, and not on anything else on the blockchain. As a consequence, the validity of a transaction can be checked off-chain, before the transaction is sent to the blockchain. This approach provides greater efficiency and security, as it allows for faster transaction processing and reduces the risk of errors.
In contrast, an account-based model (as used by Ethereum) can result in a transaction failing in mid-script execution. This can never happen in EUTXO, as the validity of a transaction is determined solely by the transaction itself and its inputs. This approach provides greater reliability and security, making it a valuable addition to blockchain networks like Cardano.
The EUTXO model also provides greater privacy, as each UTXO can only be consumed once and as a whole. This approach ensures that each transaction is verified and validated by the network, making it more secure and less prone to errors. Additionally, the EUTXO model allows for more complex and customizable scripts to be used in transactions, providing greater flexibility and security.
Also, EUTXO offers a high degree of parallelism that is possible due to the 'local' nature of transaction validation. In principle, a node could validate transactions in parallel, as long as those transactions do not try to consume the same input. This approach provides greater efficiency and simplifies the analysis of possible outcomes, making it easier to prove that 'nothing bad' can happen.
Another powerful feature of the EUTXO model is that the fees required for a valid transaction can be predicted precisely prior to posting it. This is a unique feature not found in account-based models. Account-based blockchains, like Ethereum, are indeterministic, which means that they cannot guarantee the transaction's effect on-chain. This uncertainty presents risks of monetary loss, unexpectedly high fees, and additional opportunities for adversarial behavior.
In contrast, the EUTXO model provides greater security, smart contract execution cost predictability (without unpleasant surprises), and more powerful parallelization. This approach ensures that each transaction is verified and validated by the network, making it more secure and less prone to errors. Additionally, the EUTXO model allows for more complex and customizable scripts to be used in transactions, providing greater flexibility and security.
The EUTXO model is a valuable addition to blockchain networks like Cardano, as it provides a more secure and efficient way of managing transactions. By allowing for greater parallelism and predictability, the EUTXO model ensures that each transaction is verified and validated by the network, making it more secure and less prone to errors. Additionally, the EUTXO model allows for more complex and customizable scripts to be used in transactions, providing greater flexibility and security.
In conclusion, the EUTXO model used by Cardano offers several unique advantages over other accounting models. The high degree of parallelism that is possible due to the 'local' nature of transaction validation provides greater efficiency and simplifies the analysis of possible outcomes. Additionally, the EUTXO model provides greater security, smart contract execution cost predictability (without unpleasant surprises), and more powerful parallelization. This approach ensures that each transaction is verified and validated by the network, making it more secure and less prone to errors.
A smart contract is a digital agreement that is automated and written in code. It is designed to track, verify, and execute binding transactions between multiple parties. The smart contract code is programmed to automatically execute the transactions when specific conditions are met. This means that a smart contract is essentially a short program that uses transactions on a blockchain as its inputs and outputs.
One of the key benefits of smart contracts is that they are self-executing and reliable. They do not require the presence or actions of third parties, which makes them more efficient and cost-effective. The smart contract code is stored on a decentralized blockchain network, which makes it transparent and irreversible.
Smart contracts are also immutable, which means that once a contract is created, it cannot be changed. This makes them more secure and tamper-proof. Additionally, smart contracts are distributable, which means that they can be shared across multiple parties. This makes them faster and more cost-effective, as there is no need for a middleman.
Smart contracts are also fast and cost-effective. Since there is no middleman involved, the transactions are executed quickly and at a lower cost. This is because no fees are associated with intermediaries, saving both time and money.
Another key benefit of smart contracts is that they are safe due to encryption. The smart contract code is encrypted, which means that it is secure and cannot be tampered with. This makes smart contracts an ideal solution for applications that require a high level of security, such as financial transactions.
In conclusion, smart contracts are a powerful tool for automating and executing digital agreements. They are fast, cost-effective, and secure, making them an ideal solution for a wide range of applications. Smart contracts are immutable, distributable, tamper-proof, and safe due to encryption. They are a game-changer in the world of digital transactions and have the potential to revolutionize the way we make contracts.
Cardano, a blockchain platform, introduced smart contract support in 2021. This multi-functional environment enables the development and deployment of smart contracts using various programming languages, such as:
Plutus: Plutus is a smart contract development and execution platform that is purpose-built for blockchain technology. Plutus' contracts are composed of two parts: on-chain code and off-chain or client code. The on-chain code runs on the blockchain, while the off-chain code runs on a user's machine.
Plutus is designed to provide a safe and secure programming environment for smart contract development.

It includes various features, such as a built-in wallet, a transaction submission API, and a contract testing framework. These features make it easier for developers to create, test, and deploy smart contracts on the Cardano blockchain.
Marlowe is a domain-specific language (DSL) that is specifically designed for writing and executing financial contracts. It is a powerful tool that allows developers to build contracts visually, as well as in more traditional code. Financial institutions can use Marlowe to develop and deploy custom instruments for their customers and clients.
One of the key benefits of Marlowe is that it is easy to use and accessible to developers with varying levels of experience. The language is designed to be intuitive and user-friendly, which makes it ideal for developers who are new to smart contract development. Additionally, Marlowe is designed to be flexible and adaptable, which means that it can be used for a wide range of applications.
Marlowe is also highly customizable, which makes it an ideal solution for financial institutions that want to create custom financial instruments for their clients. The language allows developers to create contracts that are tailored to their clients' specific needs and requirements. This means that financial institutions can offer their clients a wider range of financial products and services, which can help to increase customer satisfaction and loyalty.
The Marlowe language is now embedded in both JavaScript and Haskell, which offers a choice of editors depending on developers' preferences and skill sets. This means that developers can choose the editor that best suits their needs and skill level. Additionally, the Marlowe language is constantly evolving and improving, which means that developers can expect to see new features and capabilities added over time.
Cardano is a popular topic in the blockchain world, and common questions include its transaction time and the number of network confirmations required for a transaction to be processed. To answer these questions, it's essential to understand the concepts of chain confirmation and transaction confirmation and their relationship with the Cardano protocol.
Chain Confirmation
In blockchain technology, there is a point at which the chain is guaranteed not to change any further due to random events or randomness. This assurance is provided by the protocol itself. Chain confirmation is a process that takes place at a future point in time after a specific number of future k blocks have been minted.
The time interval between the present moment and when chain confirmation occurs for a particular transaction is referred to as the stability window. This window represents the number of slots needed for a block to achieve stability, where a stable block is defined as one that cannot be rolled back.
To calculate the stability window, the formula 3k/f is used, where k represents the security parameter in the genesis block, and f is the active slot coefficient parameter in the genesis block. The active slot coefficient determines the probability of the number of blocks created within an epoch.
Understanding the stability window is crucial for grasping the concept of chain confirmation and the security of a blockchain network. It ensures that transactions are processed and confirmed in a reliable and secure manner, preventing potential issues such as double-spending or other malicious activities.
In conclusion, the stability window is an essential aspect of blockchain technology, as it guarantees the immutability of the chain and ensures the security of transactions. The formula 3k/f is used to calculate this window, taking into account the security parameter and active slot coefficient parameter in the genesis block. This concept plays a vital role in maintaining the integrity and reliability of a blockchain network.
Transaction Confirmation
A transaction becomes immutable when it is accepted into the blockchain, and this point in time is crucial for ensuring the security and integrity of the network. Two key concepts related to this process are block depth and settlement window.
Block depth refers to the position of a block within the blockchain, indicating how many blocks have been added to the chain since the specific block was appended. Transactions within a block also have depth, which is directly related to the depth of the block containing them. A transaction is considered confirmed if the block containing it has a depth greater than a predefined threshold. Once a transaction reaches this level of confirmation, the protocol guarantees its immutability and the assets involved in the transaction can be safely used for trading, exchanging, and other purposes.
The settlement window is the time period between the confirmation of a transaction and the point when the assets involved in the transaction can be exchanged with other assets. This window is essential for ensuring the security of the network and preventing issues such as double-spending or other malicious activities. During the settlement window, the network verifies the transaction's validity and ensures that the assets involved have not been used in any other transactions.
In summary, the concepts of block depth and settlement window play a crucial role in maintaining the security and integrity of a blockchain network. Block depth is a relative measure that indicates the position of a block within the chain, and transactions within a block also have depth. A transaction is considered confirmed when the block containing it has a depth greater than a predefined threshold, and the protocol guarantees its immutability. The settlement window is the time period between the confirmation of a transaction and the point when the assets involved can be exchanged with other assets, ensuring the security of the network and preventing potential issues. Understanding these concepts is essential for grasping the inner workings of a blockchain network and the processes that ensure the safety and reliability of transactions.
Likelihood of Immutability
Determining the confirmation status of a transaction can be approached by assessing its potential for immutability. The immutability of a transaction relies on the number of blocks appended to the chain since its acceptance. With each additional block, the likelihood of the transaction becoming immutable increases.
The immutability threshold is reached when the transaction's depth surpasses 3k/f slots (equivalent to 129600 slots on the current mainnet or approximately 36 hours). For example, if the transaction is included in a block at slot 10, it will only achieve true immutability at slot 129600. The Ouroboros Praos protocol ensures this guarantee.
However, in most cases, the requirements are typically fulfilled before 3k/f slots have elapsed. Hence, a practical approach is to assess the probability of a transaction becoming immutable. In such cases, a transaction is considered confirmed when the probability of achieving immutability is sufficiently high.
Understanding the concept of transaction confirmation and immutability is crucial for grasping the inner workings of a blockchain network. The Ouroboros Praos protocol plays a vital role in ensuring the security and integrity of the network by guaranteeing transaction immutability. By considering the probability of a transaction becoming immutable, users can determine whether a transaction is confirmed and can be safely used for trading, exchanging, and other purposes.
In conclusion, the likelihood of a transaction's immutability is an essential factor in determining its confirmation status. The Ouroboros Praos protocol guarantees immutability once a transaction's depth exceeds 3k/f slots. However, a more practical approach involves considering the probability of a transaction becoming immutable, with a transaction considered confirmed if the probability is high enough. This understanding is crucial for maintaining the security and integrity of a blockchain network and ensuring the reliability of transactions.
Consensus is the key to running a blockchain successfully. It requires all participants to agree on the blocks to produce and the single state of the network. The consensus protocol determines how nodes assess the current state of the ledger system and reach a consensus. Blockchains reach consensus by bundling transactions into blocks and adding them to the chain. The order of the blocks in the chain is determined by the consensus protocol. This is important because it ensures that the blockchain remains secure and tamper-proof.
Different consensus protocols exist to determine who is allowed to produce a block when and what to do in case of conflicts. For example, in Proof of Work (PoW) consensus, participants compete to solve complex mathematical problems to add a block to the chain. This approach requires a lot of computational power and energy consumption. In contrast, Proof of Stake (PoS) consensus allows participants to add blocks based on their stake in the network. This means that the more stake a participant has, the more likely they are to be chosen to add a block.
Overall, the consensus protocol is critical to the functioning of any blockchain. It ensures that all participants agree on the current state of the ledger system and provides security and immutability to the blockchain. The choice of consensus protocol can have significant implications for the efficiency, security, and sustainability of a blockchain.
Cardano's consensus protocol is Ouroboros, which has undergone rigorous security analysis and presented at leading cybersecurity and cryptography conferences and publications. Unlike proof-of-work protocols that use miners to solve complex equations to create new blocks, Cardano's proof-of-stake protocol selects stake pools to create new blocks based on their stake in the network. This means that nodes with higher stakes have a higher chance of creating blocks and earning rewards. This mechanism incentivizes nodes to hold and stake their ADA coins to participate in block production and earn rewards. Proof of stake is more energy-efficient than proof of work, as it does not require the intense computational power needed for mining. Instead, it relies on a decentralized network of nodes that validate transactions and produce new blocks. Cardano's proof of stake algorithm is designed to be secure, resistant to attacks, and to ensure the long-term sustainability of the network.
Ouroboros is a consensus protocol used in the Cardano blockchain, which divides time into epochs, each further divided into slots. The primary goal of grouping slots into epochs is to adjust the leader election process according to the dynamically changing stake distribution. During a slot, a block can be created, and once the epoch ends, the new leader election process starts.
The protocol is designed to ensure security in the presence of attacks. The purpose of this is to adjust the leader election process to the ever-changing stake distribution. Each slot is a brief period in which a block can be created, and a slot leader is elected for each slot. The slot leader is responsible for adding a block to the chain and passing it to the next slot leader.
To safeguard against adversarial attempts to subvert the protocol, each new slot leader must consider the last few blocks of the received chain as transient. This means that only the chain preceding the prespecified number of transient blocks is considered settled. This is called the settlement delay. One of the benefits of this is that a stakeholder can be offline and still be synced to the blockchain, as long as it's not for more than the settlement delay.
Ouroboros uses a built-in tolerance mechanism to prevent attackers from spreading alternate versions of the blockchain. It also assumes that an adversary may send arbitrary messages to any participant at any time. However, the protocol guarantees security in a synchronous setting, which means that there are strong guarantees on message delivery times. Security is guaranteed as long as more than 51% of the stake is under the control of honest participants following the protocol.
The Ouroboros protocol requires every network node to maintain its own copy of the transaction mempool, where transactions are added only if they're consistent with existing ones. Additionally, each node stores a copy of the blockchain, which is replaced when the node is made aware of a more extended and legitimate chain. This ensures the integrity and security of the blockchain network.
Overall, Ouroboros aims to achieve a secure and decentralized blockchain network. The protocol's design ensures that the network remains secure against attacks, making it an ideal choice for applications that require a reliable and secure blockchain network. The slot and epoch system is a unique feature of Ouroboros, which helps it adapt to the dynamically changing stake distribution. With the built-in tolerance mechanism and guaranteed security, Ouroboros is a robust consensus protocol that is vital to the success of Cardano.
Implementations
Ouroboros comes in different versions and implementations:
Ouroboros Classic
Ouroboros BFT
Ouroboros Praos
Ouroboros Genesis
Ouroboros Crypsinous
Ouroboros Chronos
Ouroboros Classic
The first implementation of Ouroboros achieved three major milestones:
The foundation for an energy-efficient protocol to rival proof of work
The introduction of the mathematical framework to analyze proof of stake
The implementation of a novel incentive mechanism to reward participants in a proof-of-stake setting
Ouroboros' ability to generate unbiased randomness is critical to maintaining the protocol's security, as it prevents the formation of patterns that could be exploited by attackers. The randomness is generated through a process called verifiable random functions (VRFs), which provide cryptographic proof that the output is unpredictable and unbiased. This ensures that the leader selection algorithm is fair and unpredictable, giving all stakeholders an equal chance of being chosen as slot leaders. The rigorous security analysis applied to Ouroboros has helped to build confidence in the protocol, and it has been deployed on several blockchains, including the Cardano network. As the blockchain industry continues to evolve, the ability to generate unbiased randomness will likely become an increasingly important factor in ensuring the security and fairness of blockchain protocols.
Ouroboros BFT
Ouroboros Byzantine Fault Tolerance (BFT) was the protocol's second implementation, used during the Byron update to the Cardano codebase. It prepared the blockchain for the decentralization that came with the Shelley release. Ouroboros BFT allowed for synchronous communication between a network of federated servers, ensuring consensus on the ledger in a simpler and more deterministic way. This was an essential step towards achieving a fully decentralized system, as it laid the groundwork for the more complex and secure Ouroboros Praos protocol used in the Shelley release. The BFT version was intended to ensure a smoother transition to the Shelley update and to help Cardano scale effectively while maintaining a high level of security.
Ouroboros Praos
Ouroboros Praos is the third implementation of the Ouroboros protocol, which introduced significant security and scalability enhancements to the original Ouroboros Classic. The Praos version processes transaction blocks by dividing chains into slots, which are then aggregated into epochs. However, unlike Ouroboros Classic, Praos is analyzed in a semi-synchronous setting and is secure against adaptive attackers. The protocol achieves this by utilizing private-leader selection and forward-secure, key-evolving signatures. These mechanisms ensure that a strong adversary cannot predict the next slot leader and launch a focused attack, such as a DDoS attack. Praos also improves the protocol's overall scalability by allowing the selection of numerous slot leaders within each epoch, thus reducing network delays and enhancing overall performance. These security and scalability improvements made Ouroboros Praos a crucial update to the protocol, which further prepared Cardano for the Shelley release and the decentralized future of the blockchain.
Ouroboros Genesis
Ouroboros Genesis is the fourth iteration of the Ouroboros protocol, which is currently under development. It is expected to build upon Ouroboros Praos by introducing a new chain selection rule that allows nodes to start from a genesis block without relying on trusted checkpoints or previous availability assumptions. Additionally, the Genesis paper provides evidence of the protocol's Universal Composability, which confirms that it can be integrated with other protocols in real-world settings without compromising its security properties. This feature is crucial for ensuring that the Ouroboros protocol can be adopted in a wide range of applications and use cases. Ouroboros Genesis aims to provide an even more secure, scalable, and decentralized blockchain protocol, suitable for a variety of real-world applications, from finance to voting systems.
Ouroboros Crypsinous
With Ouroboros Crypsinous, privacy is added to the security features of the protocol. It is the first privacy-preserving proof-of-stake blockchain protocol that has been formally analyzed and is secure against adaptive attacks while maintaining strong privacy guarantees. The privacy features are achieved through a new coin evolution technique that relies on SNARKs and key-private forward-secure encryption. Although Crypsinous is not currently planned to be implemented on Cardano, other chains can use it to increase privacy-preserving settings. By enabling transactions to be conducted anonymously, Ouroboros Crypsinous has the potential to address one of the most significant criticisms of blockchain technology—its lack of privacy.
Ouroboros Chronos
Chronos is a blockchain protocol that solves two crucial problems: synchronizing clocks securely and providing a cryptographically secure source of time to other protocols. By using a novel time synchronization mechanism, Chronos enables blockchain protocols to become independent of external time services, making the ledger more resistant to attacks that target time information. Additionally, Chronos can enhance the resilience of critical infrastructures, such as telecommunications and transport, that require the synchronization of local time to a unified network clock with no single point of failure.
Chronos represents a significant advancement in the field of distributed systems and is a powerful tool for developers seeking to build decentralized applications that require accurate and secure time information. With Chronos, developers can rely on a highly accurate and tamper-resistant time source, making their applications more resilient to attacks and more reliable in general. Overall, Chronos is an important step forward in the ongoing effort to build a more secure, resilient, and decentralized internet.

As the image above suggests, Cardano’s journey splits into five phases:
Byron
Shelley
Goguen
Basho
Voltaire
Cardano, a cutting-edge third-generation blockchain, emerged through an extensive process of research, peer review, and meticulous formal development. Its inception in 2015 was driven by a vision to overcome the significant challenges confronting blockchain networks: scalability, interoperability, and sustainability. This ambitious undertaking entailed years of dedicated effort, with numerous GitHub commits and countless hours of study, culminating in the release of the first version of Cardano in September 2017, marking the beginning of the Byron era.
During the initial phase of Cardano's evolution, users were empowered to engage in the buying and selling of the ADA cryptocurrency, affectionately named after the pioneering programmer ADA Lovelace. This was made possible through a federated network that harnessed the ground-breaking Ouroboros consensus protocol. Serving as the backbone of the Cardano network, Ouroboros holds the distinction of being the first proof-of-stake protocol based on rigorous academic research and boasting mathematically-proven security.
Within the Byron era, notable milestones included the launch of the Daedalus wallet, the official desktop wallet for ADA developed by IOHK, and Yoroi, a lightweight wallet crafted by Emurgo, IOHK's sister company, designed for seamless and efficient day-to-day transactions.

Researcher, Enthusiast, Blockchain and Crypto Lover, Cryptography Lover, Ethereum is the King.
Cryptocurrencies and blockchain technology have evolved significantly since the advent of Bitcoin in 2009. The technology underlying cryptocurrencies and blockchain has grown and matured, giving rise to various types of blockchain platforms, including layer-1 platforms.
A crucial component of the blockchain ecosystem is layer-1 platforms, which serve as the foundation of the technology. These platforms are responsible for providing the fundamental functionalities that enable blockchain-based systems to function, allowing for the creation and operation of decentralized applications (dApps).
As the base layer of the blockchain stack, layer-1 platforms play a vital role in the infrastructure of blockchain technology. They are responsible for creating and validating blocks, maintaining the consensus mechanism, and managing transactions. These functionalities are crucial for the proper operation of decentralized applications, as they ensure that the data stored on the blockchain is accurate and secure.
Layer-1 platforms differ from other types of blockchain platforms, such as layer-2 scaling solutions or blockchain interoperability protocols. While layer-2 solutions aim to improve the scalability and efficiency of the existing blockchain infrastructure, layer-1 platforms focus on building a robust and scalable blockchain infrastructure from scratch. Layer-1 platforms provide a complete and self-sufficient ecosystem for decentralized applications to operate, without the need for external dependencies.
Scalability has been a major concern for blockchain platforms, especially for earlier platforms such as Bitcoin and Ethereum. These platforms have faced challenges with high transaction fees and slow transaction processing times due to their limited transaction throughput. However, layer-1 platforms have emerged as a solution to this scalability problem.
Layer-1 platforms, such as Solana and Cardano, use advanced consensus mechanisms like Proof of Stake (PoS) or Delegated Proof of Stake (DPoS) to achieve higher transaction throughput and scalability. PoS allows faster transaction processing times while reducing energy consumption, making it a more environmentally friendly alternative to older consensus mechanisms like Proof of Work (PoW). DPoS involves a smaller group of validators, who are elected by token holders to validate transactions, leading to faster transaction processing times and a more efficient network.
By adopting these advanced consensus mechanisms, layer-1 platforms can handle a larger volume of transactions and achieve higher scalability while maintaining decentralization. This has made them more appealing to developers who require a more efficient and scalable blockchain infrastructure to build decentralized applications.
Another advantage of layer-1 platforms is their ability to offer greater flexibility and control over the blockchain infrastructure. This is because they are not bound by the limitations of existing blockchain infrastructure and can create a completely self-sufficient ecosystem for decentralized applications to operate. This allows developers to create more complex and sophisticated, decentralized applications with greater ease and flexibility.
Although most of the privacy blockchains don’t include in the definition of layer-1 platforms in today’s modern definition, I decided to take a look at them before going further.
Layer-1 platforms have become increasingly popular due to their ability to provide enhanced security and privacy features that were previously unavailable on earlier blockchain platforms. Two examples of such platforms are Zcash and Monero.
These platforms utilize advanced cryptography to provide enhanced privacy and anonymity features that can protect users from data breaches, identity theft, and other types of cyberattacks. These features make layer-1 platforms ideal for use cases that require higher levels of security and privacy, such as financial transactions and sensitive data management.
Zcash, for instance, provides a feature called “shielded transactions,” which enables users to protect their transaction data from being viewed by third parties. Monero, on the other hand, utilizes ring signatures, which enable users to mask their transaction information by combining it with other users' information in a ring structure.
The use of advanced cryptography on layer-1 platforms ensures that transactions and data are securely stored and transmitted. This is particularly important for organizations and individuals who require the highest levels of security and privacy to protect their sensitive data from unauthorized access.
In addition, layer-1 platforms also offer greater control over user data, as users can choose whether to reveal their identities or not. This allows users to participate in decentralized applications and transactions without compromising their personal information.
The growth and adoption of the blockchain ecosystem largely depend on the success of layer-1 platforms. With the development and deployment of more decentralized applications on the blockchain, the need for a robust and scalable infrastructure becomes increasingly vital. Layer-1 platforms play a crucial role in providing the foundation for building decentralized applications that can meet the demands of a global user base.
The importance of layer-1 platforms lies in their ability to provide core functionalities that allow for the creation and validation of blocks, maintenance of the consensus mechanism, and management of transactions. These platforms offer a complete and self-sufficient ecosystem for decentralized applications to operate without external dependencies.
As the adoption of blockchain technology continues to grow, layer-1 platforms such as Ethereum, Solana, and Cardano have emerged as prominent players in the market. They provide advanced features such as enhanced security, privacy, and scalability to meet the requirements of different use cases.
One of these Layer-1 platforms is Cardano. Cardano is a pioneering decentralized third-generation blockchain platform and home to the ADA cryptocurrency. It is the first blockchain platform to be developed with a research-first-driven approach and a scientific philosophy. This makes it a revolutionary system, designed to meet the needs of a rapidly changing world.
The Cardano platform is built on a unique architecture that allows for scalability and interoperability. This means that it can be used as a platform for various applications and services, from finance to health and beyond.
The Cardano platform also features several technologies, such as smart contracts and sidechains, that make it possible for developers to create powerful decentralized applications. This makes it a great choice for businesses looking to build secure and reliable applications.
Finally, Cardano is open source, meaning it is free and accessible to anyone, regardless of their technical background. This makes it an ideal platform for those looking to start with blockchain technology.
The Cardano platform has been developed with sustainability and scalability in mind. It has been designed from scratch by top engineers and academic experts in the fields of blockchain and cryptography, with a strong focus on security, transparency, and inclusivity. By leveraging the power of a functional programming language, like Haskell, and utilizing formal and executable specifications, property-based testing, and simulation testing, the Cardano platform can provide a safe and secure infrastructure for financial and social applications.
Cardano’s primary goal is to provide reliable, secure financial services to those who currently don’t have access to such services. It seeks to be more advanced than any other protocol that has been developed and serves as a stable and secure platform for the development of enterprise-level dApps. To aid in this effort, Cardano will be implementing a democratic governance system that is designed to evolve and fund itself sustainably through a treasury system.
The Cardano platform also provides a secure and reliable platform for the development of enterprise-level dApps. It has a development environment that supports multiple languages including Haskell, Rust, and C++, allowing developers to create custom dApps and tokens. It also has a built-in wallet and supports a wide range of cryptocurrencies and tokens.
In addition to its development environment and consensus algorithm, the Cardano platform also features a secure, open-source wallet. This wallet provides an easy-to-use interface for securely managing funds and also supports a wide range of cryptocurrencies and tokens. It also features a built-in security system that helps protect users against malicious attacks.
The first generation of blockchains, such as Bitcoin, ushered in a new era of secure cryptocurrency transfer. They have been a major cornerstone of the blockchain revolution, as they have allowed users to transfer funds without any type of middleman or other third-party interference. This was a major development in the financial world, as it allowed users to have complete control over their funds, and ensured that all transactions were secure and immutable.
In addition to this, the first generation of blockchains also provided users with a distributed ledger system. This means that all transactions are recorded on a public ledger, allowing users to view and verify the accuracy of all transactions. This provides a level of transparency that was previously not possible with traditional financial systems.
However, the first generation of blockchains had several limitations. They were limited in terms of their functionalities, as they could not handle complex smart contracts and decentralized applications (DApps). This limited their usefulness and prevented them from being used for more than just cryptocurrency transfers.
Enter the second generation of blockchains, such as Ethereum. This new generation of blockchains addressed many of the limitations of the first generation and provided users with a platform for writing and executing smart contracts and developing decentralized applications. This allowed developers to create a variety of applications and services, ranging from financial services to gaming and social media platforms.
On the other hand, the second generation of blockchains often faces issues in terms of scalability. This means that the blockchain can only process a limited number of transactions at a given time, which can cause delays and network congestion. As a result, the blockchain may not be able to keep up with the demand of users and applications, which can lead to decreased performance and efficiency.
Despite these issues, the second generation of blockchains has been a major step forward in the development of blockchain technology. It has opened up a world of possibilities, allowing users to create a variety of applications and services on the blockchain. This has the potential to revolutionize many industries and bring about a new wave of innovation.
Cardano is a third-generation blockchain technology platform, conceived to meet the needs of users and provide them with the highest level of security, scalability, and functionality. Unlike prior generations of blockchains, Cardano is designed to combine the advantages of both and evolve to meet the changing needs of its users.
To meet these needs, Cardano has taken a unique approach to blockchain security, scalability, and functionality. In terms of security, Cardano uses a unique consensus mechanism called Ouroboros, which is designed to ensure the security of the network. This mechanism is based on a proof-of-stake algorithm, which is designed to protect the network from malicious actors.
In terms of scalability, Cardano is designed to handle large amounts of data, transactions, and network bandwidth. This is achieved through a sophisticated system of sidechains, which allows for the efficient processing of large amounts of data without compromising the security of the network.
In terms of functionality, Cardano provides a wide range of services and features to its users, including smart contracts and decentralized applications. This allows users to create and execute contracts and applications without the need for a central authority.
Finally, Cardano is designed to be interoperable with other blockchains and financial institutions. This allows users to take advantage of the best features of multiple blockchains and financial institutions, increasing the flexibility and scalability of the platform.
To address these needs, Cardano focuses on core concepts, such as:
Scalability: Cardano places great importance on scalability, as it ensures that the network can process more transactions as user demand increases. This is crucial to prevent delays or network congestion during times of high traffic. Additionally, Cardano is implementing several techniques to enhance its scalability, such as data compression to reduce the amount of data transferred during transactions.
Moreover, Cardano is working on introducing Hydra, which is expected to provide additional scalability benefits. It will allow for the creation of multiple side chains, which will help to further distribute the network's transaction processing load. This will enable Cardano to handle significantly higher transaction volumes without compromising on speed or security.
Interoperability: Interoperability is an essential feature for blockchain platforms, as it allows users to interact with multiple currencies across various blockchains. Cardano is being developed with interoperability in mind to create a multi-functional environment for financial, business, or commercial operations. In addition to supporting cross-chain transfers, Cardano will also support multiple token types and commonly used smart contract languages.
Furthermore, Cardano aims to ensure interoperability with centralized banking entities, which is crucial for granting legitimacy and convenience of use to the platform. This will enable users to easily transfer funds between traditional banking systems and the blockchain, opening up new possibilities for businesses and individuals.
Sustainability: To ensure a self-sustaining proof-of-stake blockchain, Cardano is designed to enable the community to maintain its development in a truly decentralized manner. The treasury system is controlled by the community, and potential sources for its constant refilling include newly-minted coins held back as funding, a percentage of stake pool rewards, and transaction fees. This approach enables growth and maturity to be driven by the community through their participation, proposals, and implementation of system improvements, ensuring the sustainability of the platform.
Academic research: Cardano's development is based on academic research using formal methods like mathematical specifications, proofs, and property-based tests, which provides users with greater confidence in managing digital funds. This approach ensures the high assurance of software systems and core components of the Cardano platform, enabling strong guarantees of functional correctness. The development of Cardano is transparent as all research and technical specifications are publicly available, and all development activities are published online. This openness provides the community with a clear understanding of the platform's capabilities, how it functions, and its potential limitations, allowing for a collaborative approach to its ongoing development.
System design: Cardano's system is designed using Haskell, a functional programming language that promotes creating a system using pure functions that can be tested in isolation. Haskell also offers advanced features that enable Cardano to use various powerful methods for ensuring the correctness of its code. Cardano is built on formal and executable specifications, extensive property-based testing, and running tests in simulation. All these measures contribute to a more secure and robust system that is better able to ensure the safety and security of users' funds.
Security: The security of Cardano is ensured through the use of Ouroboros, a proof-of-stake protocol that provides strict security guarantees. The development of Ouroboros was based on several peer-reviewed papers that were presented at prestigious cybersecurity and cryptography conferences and published in respected academic publications. Through this rigorous approach, Cardano can ensure that the security of the network is maintained at all times, protecting users' digital assets and transactions from potential threats.
Energy efficiency: Cardano has a much more energy-efficient approach compared to other blockchain platforms like Bitcoin. This is because Cardano uses a proof-of-stake consensus algorithm, which requires much less computational power than the proof-of-work algorithm used by Bitcoin. In proof-of-work systems, computers compete to solve complex mathematical problems to validate transactions and add them to the blockchain, which consumes a lot of energy. On the other hand, in proof-of-stake systems like Cardano, validators are chosen based on the amount of cryptocurrency they hold, and they are responsible for verifying transactions and creating new blocks. Since this process is less energy-intensive, Cardano has a much smaller carbon footprint compared to Bitcoin. This energy efficiency is crucial for the sustainability of the blockchain in the long term, as it helps to reduce the environmental impact of the platform.
Seamless upgrades: Cardano's approach to upgrading is unique compared to traditional blockchains. Upgrades to blockchains are typically achieved through hard forks, which require the existing protocol to stop working, new rules to be implemented, and the chain to restart, losing its previous history. On the other hand, Cardano uses “hard-fork combinator technology” to handle hard forks. This approach allows for a seamless transition to a new protocol while preserving the history of previous blocks and avoiding any disruptions for end-users. The hard-fork combinator technology allows for the creation of multiple parallel ledgers running in parallel, all following the same rules. The technology enables the introduction of new features while maintaining backward compatibility, which ensures that the blockchain remains functional for users throughout the upgrade process. The hard-fork combinator technology works by allowing the new protocol to operate alongside the old one. If the new protocol is successful, all nodes automatically switch to it. If the new protocol fails, the network reverts to the old one, avoiding any damage or disruptions. By using the hard-fork combinator technology, Cardano is making it possible to upgrade its blockchain without sacrificing its integrity, stability, and security. This technology allows Cardano to evolve and improve over time, providing better services and features to its users while maintaining the highest standards of security and decentralization.
Decentralization: Cardano is a decentralized network that relies on nearly 3,000 stake pools operated by the community to maintain the system. There is no centralized authority involved in the validation of blocks and transactions, which are all verified by network participants.
Functional environment for business use cases: Cardano is creating a functional environment that can be used for various business purposes. It aims to create a decentralized finance ecosystem where developers can build decentralized applications (DApps) using functional and domain-specific smart contracts. This enables the creation of multi-asset tokens that can be used for a variety of purposes, making them flexible and efficient for any business need.
A hard fork is a significant alteration in a blockchain's protocol, resulting in changes to how the blocks are processed, verified, or interpreted. This type of change can be necessary to implement new features or to fix critical vulnerabilities in the blockchain's security. Hard forks can also result in the creation of a new cryptocurrency, as the forked chain may have different rules, tokens, and values from the original chain. However, hard forks can also lead to the fragmentation of the community and network effect, as different groups may disagree on the direction and implementation of the protocol changes.
One of the most famous examples of a hard fork was the Bitcoin hard fork that occurred in August 2017. Bitcoin Cash was created as a result of the hard fork, and it aimed to improve upon the original Bitcoin protocol by increasing the block size limit, which would allow for faster and more efficient transactions.
Another example of a hard fork is the Ethereum hard fork that occurred in 2016. The DAO (Decentralized Autonomous Organization) was a smart contract on the Ethereum blockchain that aimed to create a decentralized venture capital fund. However, a vulnerability was exploited, and funds were drained from the DAO. In response, the Ethereum community conducted a hard fork, which resulted in the creation of Ethereum and Ethereum Classic.
Hard forks can be a contentious issue within the blockchain community, with some arguing that they go against the decentralized nature of the technology. However, they can also be a necessary step for improving the security and efficiency of the blockchain.
It is worth noting that not all blockchain upgrades require a hard fork. In some cases, soft forks can be used instead. Soft forks are backwards-compatible upgrades that do not require a change to the blockchain's protocol. This means that they are less disruptive and have less potential for causing a chain split.
Ultimately, the decision to conduct a hard fork or a soft fork will depend on the specific circumstances and the goals of the blockchain developers. It is important for the community to come to a consensus on the need for a hard fork and to communicate the changes to users to minimize any potential disruption.
One of the major milestones in the development of the Cardano blockchain was the transition from a federated model, called Byron, to a decentralized one, called Shelley (you can read about these phases in the Roadmap section). This transition was achieved through a hard fork, which is a process of changing the protocol rules of a blockchain. However, unlike most hard forks, which create a radical break from the previous version and erase its history, the Cardano hard fork was designed to be smooth and seamless. The chain did not undergo a drastic change, but rather preserved the history of the Byron blocks and added new Shelley blocks after a period of adjustment. This way, there was no need to start from scratch and lose the record of previous activities on the blockchain.
Hard Fork Combinator
A technical term known as a combinator is used to describe the combination of certain processes or things. In the context of Cardano, a hard fork combinator is utilized to combine protocols, allowing for a seamless transition from Byron to Shelley without any system interruption or restart. This ensures that the Byron and Shelley ledgers appear as a single ledger, providing a smooth and uninterrupted experience for users.
The hard fork combinator is designed to enable the combination of multiple protocols without requiring significant adjustments. Currently, the Cardano chain combines Byron and Shelley blocks, and future transitions will also combine Goguen, Basho, and Voltaire blocks as a single property. This combinator simplifies the previous Byron-to-Shelley evolution, making it easier to transition from Shelley to Goguen and beyond.
One of the key benefits of the hard fork combinator is that it allows nodes to update gradually, rather than requiring all nodes to update simultaneously. This means that some nodes can run Byron blocks while others run Shelley blocks, making the transition smoother and more efficient.
By utilizing the hard fork combinator, Cardano is able to combine multiple protocols seamlessly, providing a more streamlined experience for users. As Cardano continues to evolve and transition to new protocols, the hard fork combinator will play a crucial role in ensuring a smooth and uninterrupted experience for all users.
Moving from Byron Ouroboros Classic to Shelley Ouroboros Praos
Cardano's Byron mainnet was built on the Ouroboros Classic consensus protocol. Ouroboros Classic was later replaced by the new Ouroboros Praos consensus protocol in the current development era, known as Cardano Shelley mainnet (you can read about Cardano’s consensus mechanism in the Ouroboros chapter). This new protocol offers extended capabilities and supports the staking process with monetary rewards for ADA holders and stake pool owners.
To ensure a smooth transition to the new protocol without any disruptions to the system, Cardano needed to update the code to support the new protocol's conditions. However, updating the code in a single update could have caused a range of complexities. To avoid this, Cardano decided to take a two-stage approach, using the Ouroboros Byzantine Fault Tolerance (BFT) protocol as an intermediary.
The shift from Ouroboros Classic to BFT, which occurred on February 20, 2020, was the only traditional hard fork within the Cardano blockchain. This forking event restarted the Byron mainnet to run the BFT protocol, enabling a smoother transition to Ouroboros Praos without any further chain interruptions. The BFT protocol was carefully designed to ensure that the blockchain history remained unchanged, and the blockchain appeared as a single entity.
By using the BFT protocol as an intermediary, Cardano was able to ensure that the transition to the new protocol was orderly and without any diversions in the system. This approach allowed for a more seamless transition to the new protocol, which offers extended capabilities and supports the staking process with monetary rewards for ADA holders and stake pool owners.
Overall, Cardano's approach to transitioning to the new protocol demonstrates its commitment to ensuring a smooth and uninterrupted experience for users. By carefully designing the BFT protocol as an intermediary, Cardano was able to avoid any disruptions to the system and ensure that the blockchain history remained unchanged. As Cardano continues to evolve and transition to new protocols, it will undoubtedly continue to prioritize a smooth and seamless experience for all users.
Token Locking: Shelly Protocol Upgrade
Cardano's Shelley protocol is set to introduce a new feature called token locking, which will enable various smart contract use cases, including creating and transacting with multi-asset tokens and supporting the Voltaire voting mechanism. Token locking involves reserving a certain amount of assets and committing not to dispose of them for a specified period of time. This feature will be enabled in the Allegra upgrade and will allow for the recording of specific tokens being used for a certain purpose during the Mary upgrade.
The token can represent an item that is accounted for by the blockchain ledger, including ADA, but will soon include other custom token types. With the introduction of token locking, Cardano is taking another step towards enabling a more robust and versatile blockchain ecosystem. This feature allows for the creation and transacting of multi-asset tokens, which can represent a wide range of assets, including stocks, bonds, and real estate. Additionally, token locking will support the Voltaire voting mechanism, which will enable ADA holders to vote on important decisions related to the Cardano ecosystem.
You can list some of this feature’s use cases below:
Contractual agreement: When entering into a contractual agreement, such as selling a property, it is crucial to ensure that the property is not sold to anyone else but the person who pays the money. Token locking can represent the property, while the 'promise' is the actual token locking. This feature enables a more secure and reliable way to ensure that contractual agreements are upheld and that assets are not sold to unauthorized parties.
By using token locking, Cardano is taking another step towards enabling a more robust and versatile blockchain ecosystem. This feature can be used to represent a wide range of assets, including real estate, stocks, and bonds. With the ability to represent assets in this way, contractual agreements can be more easily enforced, and the risk of fraud or unauthorized sales can be minimized.
Overall, token locking is a significant development for Cardano, as it enables a more secure and reliable way to ensure that contractual agreements are upheld and that assets are not sold to unauthorized parties. With the ability to represent a wide range of assets, token locking is poised to play a crucial role in the growth and development of the Cardano blockchain ecosystem.
Vote registry: The Voltaire voting mechanism within Cardano will utilize token locking to enable users to lock a certain amount of their tokens to represent their voting rights. ADA holders who participate in the voting process will be required to 'lock' their tokens, which will represent their voting rights according to the stake they hold. This feature will eliminate the risks associated with scenarios such as double-counting votes, allocating more votes than possible, contradictory votes, or vote duplication.
By using token locking within the Voltaire voting mechanism, Cardano is taking another step towards enabling a more secure and reliable way to conduct voting processes. This feature ensures that each vote is accurately represented and that the voting process is fair and transparent. With the ability to represent voting rights in this way, Cardano is well-positioned to continue its growth and development as a leading blockchain platform.
Multi-asset tokens: Cardano is set to provide support for multi-asset tokens, which will enable the creation and use of multiple custom token types, in addition to ADA. With the introduction of multi-asset tokens, Cardano is taking another step towards enabling a more versatile and robust blockchain ecosystem. Token locking allows ADA tokens to be 'locked' to create another custom asset of equivalent value.
By using token locking to create custom assets, Cardano is enabling a more secure and reliable way to represent a wide range of assets on the blockchain. This feature will enable the creation of custom assets that can represent a wide range of assets, including stocks, bonds, and real estate. With the ability to represent assets in this way, Cardano is well-positioned to continue its growth and development as a leading blockchain platform.
Mary: multi-asset support
The Mary upgrade, implemented in March 2021, introduced native tokens and multi-asset support on the Cardano blockchain. This upgrade allows users to create uniquely defined (custom) tokens and carry out transactions with them directly on the Cardano blockchain.
With the introduction of native tokens and multi-asset support, the accounting infrastructure of the Cardano blockchain can now process transactions that simultaneously carry several asset types, including ADA. This native support grants distinct advantages for developers, as there is no need to create smart contracts to handle custom token creation or transactions. Instead, the accounting ledger tracks the ownership and transfer of assets, removing extra complexity and potential for manual errors, while ensuring significant cost efficiency.
Developers, businesses, and applications can create general-purpose (fungible) or specialized (non-fungible) tokens to achieve commercial or business objectives. These tokens can be used for a wide range of purposes, including the creation of custom payment tokens or rewards for decentralized applications, stablecoins pegged to other currencies, or unique assets that represent intellectual property. All these assets can then be traded, exchanged, or used as payment for products or services.
Overall, the Mary upgrade is a significant development for Cardano, as it enables a more versatile and robust blockchain ecosystem. With the ability to create custom tokens and carry out transactions with them directly on the blockchain, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. By removing extra complexity and the potential for manual errors, while ensuring significant cost efficiency, Cardano is taking another step towards creating a more transparent and trustworthy blockchain ecosystem.
Alonzo: smart contract support
The Alonzo protocol upgrade, implemented in September 2021 as part of the Goguen development theme, builds on top of transaction metadata, token locking, and native asset functionality to enable smart contract development on the Cardano blockchain.
This upgrade introduces a versatile platform that opens up opportunities for businesses and developers by allowing the creation of smart contracts and decentralized applications (DApps) for decentralized finance (DeFi). With the ability to create smart contracts and DApps, Cardano is taking another step towards enabling a more robust and versatile blockchain ecosystem.
To enable smart contract development, the Alonzo upgrade adds the necessary tools and infrastructure using the Plutus Platform. Applying a rigorous approach based on formal methods and verification, Alonzo extends the basic multi-signature scripting language (multisig) used in Cardano Shelley. Multisig is being upgraded to the Plutus Core language for more powerful and secure scripting options. For this, Alonzo implements the extended unspent transaction output (EUTXO) accounting model.
The Extended Unspent Transaction Output (EUTXO) model is a unique approach to blockchain architecture that allows for greater flexibility and security in the execution of smart contracts.
In traditional blockchain models, transactions are executed by updating the current state of the blockchain. This means that each transaction must be validated against the current state of the blockchain, which can be a time-consuming and resource-intensive process.
The EUTXO model, on the other hand, uses a system of “outputs” and “inputs” to execute transactions. Each output represents a specific amount of cryptocurrency that is locked to a specific script, while each input represents a reference to a previous output that has been unlocked by a specific script.
When a new transaction is created, it must reference one or more previous outputs as inputs, and it must also specify one or more new outputs that will be created as a result of the transaction. The script associated with each output determines the conditions under which the output can be spent in a future transaction.
This approach has several advantages over traditional blockchain models. First, it allows for greater flexibility in the execution of smart contracts, as each output can have its own unique script that specifies the conditions under which it can be spent. Second, it provides greater security, as each output can only be spent once and any attempt to spend it again will be rejected by the network.
Overall, the Alonzo protocol upgrade is a significant development for Cardano, as it enables a more versatile and robust blockchain ecosystem. With the ability to create smart contracts and DApps, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. By implementing the EUTXO accounting model and upgrading multisig to the Plutus Core language, Cardano is taking another step towards creating a more transparent and trustworthy blockchain ecosystem.
Vasil: Plutus 2.0 and the debut of pipelining
The Vasil protocol upgrade, named after the late Bulgarian mathematician and prominent Cardano community member Vasil Dabov, was set to be implemented in June 2022, but with a delay in launch, it was implemented in September 2022. This upgrade introduces five key mechanisms to improve the blockchain's performance: CIP-31 (Reference Inputs), CIP-32 (Inline Datums), CIP-33 (Reference Scripts), CIP-40 (Collateral Outputs), and diffusion pipelining.
These improvements boost Cardano's usability and scalability by increasing the block size limit to fit more transactions per block. With the ability to fit more transactions per block, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. Additionally, developers will have a better experience while building on Cardano, as Vasil will greatly reduce the complexity of creating and deploying DApps on Cardano.
One of the main focuses of the Vasil upgrade is Plutus scripts. These scripts will live persistently on-chain, so they can be referenced when needed, which will improve efficiency. With this feature, there will no longer be a need to include the script in the transaction attempting to spend its outputs. This improvement will enable more efficient and reliable smart contract execution on the Cardano blockchain.
Overall, the Vasil protocol upgrade is a significant development for Cardano, as it enables a more versatile and robust blockchain ecosystem. With the ability to fit more transactions per block and reduce the complexity of creating and deploying DApps on Cardano, Cardano is well-positioned to continue its growth and development as a leading blockchain platform. By improving Plutus scripts and enabling more efficient and reliable smart contract execution, Cardano is taking another step towards creating a more transparent and trustworthy blockchain ecosystem.
We mentioned the EUTXO, or the Extended UTXO model, before. It is good to discuss what this model is and how it works best for Cardano.
The Extended Unspent Transaction Output (EUTXO) model is a unique accounting model utilized by Cardano, which is an Unspent Transaction Output (UTXO)-based blockchain like Bitcoin. Unlike other account-based blockchains such as Ethereum, Cardano's ledger operates on a different accounting model. The EUTXO model is introduced by the Alonzo upgrade to support multi-assets and smart contracts, making it an innovative solution for Cardano.
Overview of the UTXO Model
The Unspent Transaction Output (UTXO) model operates on the principle that a transaction has inputs and outputs. The inputs are unspent outputs from previous transactions, and assets are stored on the ledger in unspent outputs rather than in accounts. In essence, a transaction is an action that unlocks previous outputs and creates new ones. This approach ensures that the ledger remains secure and immutable, as each transaction is verified and validated by the network.
Transaction Output
The Unspent Transaction Output (UTXO) model is a unique approach to blockchain accounting that operates on the principle that a transaction output comprises an address and a value. The address can be thought of as a lock, and the signature that corresponds to the address is the key to unlock the output. Once unlocked, an output can be used as input for a new transaction.
In the UTXO model, new transactions spend outputs from previous transactions and create new outputs that can be consumed by future transactions. Each UTXO can only be consumed once and as a whole. This means that each output can be spent by exactly one input, and one input only. This approach ensures that the ledger remains secure and immutable, as each transaction is verified and validated by the network.
The UTXO model differs from the account-based model used by other blockchains such as Ethereum. By storing assets in unspent outputs rather than accounts, the UTXO model provides a more secure and efficient way of managing transactions. The UTXO model also enables the implementation of smart contracts and multi-assets, making it a versatile solution for blockchain networks like Cardano.
The users' wallets manage the UTXOs and initiate transactions involving the UTXOs owned by the user. Each blockchain node maintains a record of the subset of all UTXOs at all times, known as the UTXO set. The UTXO set is stored in the data directory of every node and is technically referred to as the chainstate.
When a new block is added to the chain, the chainstate is updated accordingly. This new block contains the latest transactions, including a record of spent UTXOs and new ones created since the chainstate was last updated. Every node maintains an exact copy of the chainstate, ensuring that the ledger remains secure and immutable.
Extended UTXO Model
The Extended Unspent Transaction Output (EUTXO) model is an innovative solution that extends the Unspent Transaction Output (UTXO) model in two significant ways.
Firstly, the EUTXO model generalizes the concept of 'address' by using the lock-and-key analogy. Unlike the UTXO model, which restricts locks to public keys and keys to signatures, addresses in the EUTXO model can contain arbitrary logic in the form of scripts. When a node validates a transaction, it determines whether the transaction is allowed to use a certain output as an input. The transaction will look up the script provided by the output's address and will execute the script if the transaction can use the output as an input. This approach provides greater flexibility and security, as it allows for more complex and customizable scripts to be used in transactions.
Secondly, the EUTXO model allows outputs to carry (almost) arbitrary data in addition to an address and value. This makes scripts much more powerful by allowing them to carry state information. This state information can be used to implement smart contracts and other complex applications on the blockchain. By allowing outputs to carry additional data, the EUTXO model provides a more versatile and efficient way of managing transactions.
The EUTXO model is a significant improvement over the UTXO model, as it provides greater flexibility and security while maintaining the efficiency and immutability of the blockchain. The EUTXO model is introduced by the Alonzo upgrade to support multi-assets and smart contracts, making it a valuable addition to blockchain networks like Cardano.
Furthermore, EUTXO allows output addresses to contain complex logic to decide which transactions can unlock them and adds custom data to all outputs.
When validating an address in the EUTXO model, the script will access the data being carried by the output, the transaction is validated, and some additional pieces of data called redeemers, which the transaction provides for every input. By looking up all this information, the script has enough context to give a 'yes' or 'no' answer in what can be highly complex situations and use cases. This approach provides greater flexibility and security, as it allows for more complex and customizable scripts to be used in transactions.
The EUTXO model enables arbitrary logic in the form of scripts, which inspect the transaction and the data to decide whether the transaction is allowed to use an input or not. This approach provides a more secure and efficient way of managing transactions, as each transaction is verified and validated by the network, making it more secure and less prone to errors.
The EUTXO model is introduced by the Alonzo upgrade to support multi-assets and smart contracts, making it a valuable addition to blockchain networks like Cardano. By allowing for more complex and customizable scripts to be used in transactions, the EUTXO model provides greater flexibility and security while maintaining the efficiency and immutability of the blockchain.
The Unspent Transaction Output (UTXO) model used by Cardano is fundamentally different from the account-based model used by some existing smart-contract-enabled blockchains. As a result, the design patterns that work for DApps on account-based blockchains do not translate directly to Cardano. New design patterns are needed because the underlying representation of the data is different.
The Extended Unspent Transaction Output (EUTXO) model inherits the per-branches design of the UTXO (Bitcoin) model, where one branch is by definition a sequence of transactions that requires a sequence of validations. To split the logic across different branches and enforce more parallelism, it is essential to build DApps and other solutions using multiple UTXOs. This approach provides benefits in terms of scaling, just like developing Bitcoin services prerequisites splitting one wallet into sub-wallets.
By using multiple UTXOs, developers can split the logic across different branches and enforce more parallelism, which is essential for building DApps and other solutions on the Cardano blockchain. This approach provides benefits in terms of scaling, making it a valuable addition to blockchain networks like Cardano.
Advantages of EUTXO
Cardano's Extended Unspent Transaction Output (EUTXO) model is a significant improvement over other accounting models, providing a secure and versatile environment to process multiple operations without system failures. This model offers better scalability and privacy, as well as more simplified transaction logic, as each UTXO can only be consumed once and as a whole, which makes transaction verification much simpler.
The EUTXO model offers unique advantages over other accounting models. The success or failure of transaction validation depends only on the transaction itself and its inputs, and not on anything else on the blockchain. As a consequence, the validity of a transaction can be checked off-chain, before the transaction is sent to the blockchain. This approach provides greater efficiency and security, as it allows for faster transaction processing and reduces the risk of errors.
In contrast, an account-based model (as used by Ethereum) can result in a transaction failing in mid-script execution. This can never happen in EUTXO, as the validity of a transaction is determined solely by the transaction itself and its inputs. This approach provides greater reliability and security, making it a valuable addition to blockchain networks like Cardano.
The EUTXO model also provides greater privacy, as each UTXO can only be consumed once and as a whole. This approach ensures that each transaction is verified and validated by the network, making it more secure and less prone to errors. Additionally, the EUTXO model allows for more complex and customizable scripts to be used in transactions, providing greater flexibility and security.
Also, EUTXO offers a high degree of parallelism that is possible due to the 'local' nature of transaction validation. In principle, a node could validate transactions in parallel, as long as those transactions do not try to consume the same input. This approach provides greater efficiency and simplifies the analysis of possible outcomes, making it easier to prove that 'nothing bad' can happen.
Another powerful feature of the EUTXO model is that the fees required for a valid transaction can be predicted precisely prior to posting it. This is a unique feature not found in account-based models. Account-based blockchains, like Ethereum, are indeterministic, which means that they cannot guarantee the transaction's effect on-chain. This uncertainty presents risks of monetary loss, unexpectedly high fees, and additional opportunities for adversarial behavior.
In contrast, the EUTXO model provides greater security, smart contract execution cost predictability (without unpleasant surprises), and more powerful parallelization. This approach ensures that each transaction is verified and validated by the network, making it more secure and less prone to errors. Additionally, the EUTXO model allows for more complex and customizable scripts to be used in transactions, providing greater flexibility and security.

A smart contract is a digital agreement that is automated and written in code. It is designed to track, verify, and execute binding transactions between multiple parties. The smart contract code is programmed to automatically execute the transactions when specific conditions are met. This means that a smart contract is essentially a short program that uses transactions on a blockchain as its inputs and outputs.
One of the key benefits of smart contracts is that they are self-executing and reliable. They do not require the presence or actions of third parties, which makes them more efficient and cost-effective. The smart contract code is stored on a decentralized blockchain network, which makes it transparent and irreversible.
Smart contracts are also immutable, which means that once a contract is created, it cannot be changed. This makes them more secure and tamper-proof. Additionally, smart contracts are distributable, which means that they can be shared across multiple parties. This makes them faster and more cost-effective, as there is no need for a middleman.
Smart contracts are also fast and cost-effective. Since there is no middleman involved, the transactions are executed quickly and at a lower cost. This is because no fees are associated with intermediaries, saving both time and money.
Another key benefit of smart contracts is that they are safe due to encryption. The smart contract code is encrypted, which means that it is secure and cannot be tampered with. This makes smart contracts an ideal solution for applications that require a high level of security, such as financial transactions.
In conclusion, smart contracts are a powerful tool for automating and executing digital agreements. They are fast, cost-effective, and secure, making them an ideal solution for a wide range of applications. Smart contracts are immutable, distributable, tamper-proof, and safe due to encryption. They are a game-changer in the world of digital transactions and have the potential to revolutionize the way we make contracts.

This means that financial institutions can offer their clients a wider range of financial products and services, which can help to increase customer satisfaction and loyalty.
The Marlowe language is now embedded in both JavaScript and Haskell, which offers a choice of editors depending on developers' preferences and skill sets. This means that developers can choose the editor that best suits their needs and skill level. Additionally, the Marlowe language is constantly evolving and improving, which means that developers can expect to see new features and capabilities added over time.
Cardano is a popular topic in the blockchain world, and common questions include its transaction time and the number of network confirmations required for a transaction to be processed. To answer these questions, it's essential to understand the concepts of chain confirmation and transaction confirmation and their relationship with the Cardano protocol.
Chain Confirmation
In blockchain technology, there is a point at which the chain is guaranteed not to change any further due to random events or randomness. This assurance is provided by the protocol itself. Chain confirmation is a process that takes place at a future point in time after a specific number of future k blocks have been minted.
The time interval between the present moment and when chain confirmation occurs for a particular transaction is referred to as the stability window. This window represents the number of slots needed for a block to achieve stability, where a stable block is defined as one that cannot be rolled back.
To calculate the stability window, the formula 3k/f is used, where k represents the security parameter in the genesis block, and f is the active slot coefficient parameter in the genesis block. The active slot coefficient determines the probability of the number of blocks created within an epoch.
Understanding the stability window is crucial for grasping the concept of chain confirmation and the security of a blockchain network. It ensures that transactions are processed and confirmed in a reliable and secure manner, preventing potential issues such as double-spending or other malicious activities.
In conclusion, the stability window is an essential aspect of blockchain technology, as it guarantees the immutability of the chain and ensures the security of transactions. The formula 3k/f is used to calculate this window, taking into account the security parameter and active slot coefficient parameter in the genesis block. This concept plays a vital role in maintaining the integrity and reliability of a blockchain network.
Transaction Confirmation
A transaction becomes immutable when it is accepted into the blockchain, and this point in time is crucial for ensuring the security and integrity of the network. Two key concepts related to this process are block depth and settlement window.
Block depth refers to the position of a block within the blockchain, indicating how many blocks have been added to the chain since the specific block was appended. Transactions within a block also have depth, which is directly related to the depth of the block containing them. A transaction is considered confirmed if the block containing it has a depth greater than a predefined threshold. Once a transaction reaches this level of confirmation, the protocol guarantees its immutability and the assets involved in the transaction can be safely used for trading, exchanging, and other purposes.
The settlement window is the time period between the confirmation of a transaction and the point when the assets involved in the transaction can be exchanged with other assets. This window is essential for ensuring the security of the network and preventing issues such as double-spending or other malicious activities. During the settlement window, the network verifies the transaction's validity and ensures that the assets involved have not been used in any other transactions.
In summary, the concepts of block depth and settlement window play a crucial role in maintaining the security and integrity of a blockchain network. Block depth is a relative measure that indicates the position of a block within the chain, and transactions within a block also have depth. A transaction is considered confirmed when the block containing it has a depth greater than a predefined threshold, and the protocol guarantees its immutability. The settlement window is the time period between the confirmation of a transaction and the point when the assets involved can be exchanged with other assets, ensuring the security of the network and preventing potential issues. Understanding these concepts is essential for grasping the inner workings of a blockchain network and the processes that ensure the safety and reliability of transactions.
Likelihood of Immutability
Determining the confirmation status of a transaction can be approached by assessing its potential for immutability. The immutability of a transaction relies on the number of blocks appended to the chain since its acceptance. With each additional block, the likelihood of the transaction becoming immutable increases.
The immutability threshold is reached when the transaction's depth surpasses 3k/f slots (equivalent to 129600 slots on the current mainnet or approximately 36 hours). For example, if the transaction is included in a block at slot 10, it will only achieve true immutability at slot 129600. The Ouroboros Praos protocol ensures this guarantee.
However, in most cases, the requirements are typically fulfilled before 3k/f slots have elapsed. Hence, a practical approach is to assess the probability of a transaction becoming immutable. In such cases, a transaction is considered confirmed when the probability of achieving immutability is sufficiently high.
Understanding the concept of transaction confirmation and immutability is crucial for grasping the inner workings of a blockchain network. The Ouroboros Praos protocol plays a vital role in ensuring the security and integrity of the network by guaranteeing transaction immutability. By considering the probability of a transaction becoming immutable, users can determine whether a transaction is confirmed and can be safely used for trading, exchanging, and other purposes.
In conclusion, the likelihood of a transaction's immutability is an essential factor in determining its confirmation status. The Ouroboros Praos protocol guarantees immutability once a transaction's depth exceeds 3k/f slots. However, a more practical approach involves considering the probability of a transaction becoming immutable, with a transaction considered confirmed if the probability is high enough. This understanding is crucial for maintaining the security and integrity of a blockchain network and ensuring the reliability of transactions.
Consensus is the key to running a blockchain successfully. It requires all participants to agree on the blocks to produce and the single state of the network. The consensus protocol determines how nodes assess the current state of the ledger system and reach a consensus. Blockchains reach consensus by bundling transactions into blocks and adding them to the chain. The order of the blocks in the chain is determined by the consensus protocol. This is important because it ensures that the blockchain remains secure and tamper-proof.
Different consensus protocols exist to determine who is allowed to produce a block when and what to do in case of conflicts. For example, in Proof of Work (PoW) consensus, participants compete to solve complex mathematical problems to add a block to the chain. This approach requires a lot of computational power and energy consumption. In contrast, Proof of Stake (PoS) consensus allows participants to add blocks based on their stake in the network. This means that the more stake a participant has, the more likely they are to be chosen to add a block.
Overall, the consensus protocol is critical to the functioning of any blockchain. It ensures that all participants agree on the current state of the ledger system and provides security and immutability to the blockchain. The choice of consensus protocol can have significant implications for the efficiency, security, and sustainability of a blockchain.
Cardano's consensus protocol is Ouroboros, which has undergone rigorous security analysis and presented at leading cybersecurity and cryptography conferences and publications. Unlike proof-of-work protocols that use miners to solve complex equations to create new blocks, Cardano's proof-of-stake protocol selects stake pools to create new blocks based on their stake in the network. This means that nodes with higher stakes have a higher chance of creating blocks and earning rewards. This mechanism incentivizes nodes to hold and stake their ADA coins to participate in block production and earn rewards. Proof of stake is more energy-efficient than proof of work, as it does not require the intense computational power needed for mining. Instead, it relies on a decentralized network of nodes that validate transactions and produce new blocks. Cardano's proof of stake algorithm is designed to be secure, resistant to attacks, and to ensure the long-term sustainability of the network.
Ouroboros is a consensus protocol used in the Cardano blockchain, which divides time into epochs, each further divided into slots. The primary goal of grouping slots into epochs is to adjust the leader election process according to the dynamically changing stake distribution. During a slot, a block can be created, and once the epoch ends, the new leader election process starts.
The protocol is designed to ensure security in the presence of attacks. The purpose of this is to adjust the leader election process to the ever-changing stake distribution. Each slot is a brief period in which a block can be created, and a slot leader is elected for each slot. The slot leader is responsible for adding a block to the chain and passing it to the next slot leader.
To safeguard against adversarial attempts to subvert the protocol, each new slot leader must consider the last few blocks of the received chain as transient. This means that only the chain preceding the prespecified number of transient blocks is considered settled. This is called the settlement delay. One of the benefits of this is that a stakeholder can be offline and still be synced to the blockchain, as long as it's not for more than the settlement delay.
Ouroboros uses a built-in tolerance mechanism to prevent attackers from spreading alternate versions of the blockchain. It also assumes that an adversary may send arbitrary messages to any participant at any time. However, the protocol guarantees security in a synchronous setting, which means that there are strong guarantees on message delivery times. Security is guaranteed as long as more than 51% of the stake is under the control of honest participants following the protocol.
The Ouroboros protocol requires every network node to maintain its own copy of the transaction mempool, where transactions are added only if they're consistent with existing ones. Additionally, each node stores a copy of the blockchain, which is replaced when the node is made aware of a more extended and legitimate chain. This ensures the integrity and security of the blockchain network.
Overall, Ouroboros aims to achieve a secure and decentralized blockchain network. The protocol's design ensures that the network remains secure against attacks, making it an ideal choice for applications that require a reliable and secure blockchain network. The slot and epoch system is a unique feature of Ouroboros, which helps it adapt to the dynamically changing stake distribution. With the built-in tolerance mechanism and guaranteed security, Ouroboros is a robust consensus protocol that is vital to the success of Cardano.
Implementations
Ouroboros comes in different versions and implementations:
Ouroboros Classic
Ouroboros BFT
Ouroboros Praos
Ouroboros Genesis
Ouroboros Crypsinous
Ouroboros Chronos
Ouroboros Classic
The first implementation of Ouroboros achieved three major milestones:
The foundation for an energy-efficient protocol to rival proof of work
The introduction of the mathematical framework to analyze proof of stake
The implementation of a novel incentive mechanism to reward participants in a proof-of-stake setting
Ouroboros' ability to generate unbiased randomness is critical to maintaining the protocol's security, as it prevents the formation of patterns that could be exploited by attackers. The randomness is generated through a process called verifiable random functions (VRFs), which provide cryptographic proof that the output is unpredictable and unbiased. This ensures that the leader selection algorithm is fair and unpredictable, giving all stakeholders an equal chance of being chosen as slot leaders. The rigorous security analysis applied to Ouroboros has helped to build confidence in the protocol, and it has been deployed on several blockchains, including the Cardano network. As the blockchain industry continues to evolve, the ability to generate unbiased randomness will likely become an increasingly important factor in ensuring the security and fairness of blockchain protocols.
Ouroboros BFT
Ouroboros Byzantine Fault Tolerance (BFT) was the protocol's second implementation, used during the Byron update to the Cardano codebase. It prepared the blockchain for the decentralization that came with the Shelley release. Ouroboros BFT allowed for synchronous communication between a network of federated servers, ensuring consensus on the ledger in a simpler and more deterministic way. This was an essential step towards achieving a fully decentralized system, as it laid the groundwork for the more complex and secure Ouroboros Praos protocol used in the Shelley release. The BFT version was intended to ensure a smoother transition to the Shelley update and to help Cardano scale effectively while maintaining a high level of security.
Ouroboros Praos
Ouroboros Praos is the third implementation of the Ouroboros protocol, which introduced significant security and scalability enhancements to the original Ouroboros Classic. The Praos version processes transaction blocks by dividing chains into slots, which are then aggregated into epochs. However, unlike Ouroboros Classic, Praos is analyzed in a semi-synchronous setting and is secure against adaptive attackers. The protocol achieves this by utilizing private-leader selection and forward-secure, key-evolving signatures. These mechanisms ensure that a strong adversary cannot predict the next slot leader and launch a focused attack, such as a DDoS attack. Praos also improves the protocol's overall scalability by allowing the selection of numerous slot leaders within each epoch, thus reducing network delays and enhancing overall performance. These security and scalability improvements made Ouroboros Praos a crucial update to the protocol, which further prepared Cardano for the Shelley release and the decentralized future of the blockchain.
Ouroboros Genesis
Ouroboros Genesis is the fourth iteration of the Ouroboros protocol, which is currently under development. It is expected to build upon Ouroboros Praos by introducing a new chain selection rule that allows nodes to start from a genesis block without relying on trusted checkpoints or previous availability assumptions. Additionally, the Genesis paper provides evidence of the protocol's Universal Composability, which confirms that it can be integrated with other protocols in real-world settings without compromising its security properties. This feature is crucial for ensuring that the Ouroboros protocol can be adopted in a wide range of applications and use cases. Ouroboros Genesis aims to provide an even more secure, scalable, and decentralized blockchain protocol, suitable for a variety of real-world applications, from finance to voting systems.
Ouroboros Crypsinous
With Ouroboros Crypsinous, privacy is added to the security features of the protocol. It is the first privacy-preserving proof-of-stake blockchain protocol that has been formally analyzed and is secure against adaptive attacks while maintaining strong privacy guarantees. The privacy features are achieved through a new coin evolution technique that relies on SNARKs and key-private forward-secure encryption. Although Crypsinous is not currently planned to be implemented on Cardano, other chains can use it to increase privacy-preserving settings. By enabling transactions to be conducted anonymously, Ouroboros Crypsinous has the potential to address one of the most significant criticisms of blockchain technology—its lack of privacy.
Ouroboros Chronos
Chronos is a blockchain protocol that solves two crucial problems: synchronizing clocks securely and providing a cryptographically secure source of time to other protocols. By using a novel time synchronization mechanism, Chronos enables blockchain protocols to become independent of external time services, making the ledger more resistant to attacks that target time information. Additionally, Chronos can enhance the resilience of critical infrastructures, such as telecommunications and transport, that require the synchronization of local time to a unified network clock with no single point of failure.
Chronos represents a significant advancement in the field of distributed systems and is a powerful tool for developers seeking to build decentralized applications that require accurate and secure time information. With Chronos, developers can rely on a highly accurate and tamper-resistant time source, making their applications more resilient to attacks and more reliable in general. Overall, Chronos is an important step forward in the ongoing effort to build a more secure, resilient, and decentralized internet.
