Traditionally, the crypto space has been riddled with complexities. Today, we're on a journey to unscramble the intricate nature of blockchains, delving deep into the revolutionary realm of the Fuel blockchain and the innovations pioneered by Fuelet Wallet.

1 - The Call for Account Abstraction

In our day-to-day digital transactions, we often wish for more flexibility, more control. Ethereum, a blockchain titan, has its merits, but it's somewhat restrictive when customizing transaction validity. Enter account abstraction. In its essence, account abstraction is a developer's wand to set the rules for transaction validity, detouring from Ethereum's basic External Owned Accounts.

So, why the buzz? The magic lies in Fuel's implementation of account abstraction, which uses predicates - stateless scripts that detail when tokens can be spent. Unlike its stateful counterparts, this design keeps validity conditions consistent, irrespective of blockchain state changes. The upshot? Developers get a detailed peek into transactions and can determine actions based on final effects.

2 - The Seedless Wave with Fuelet Wallet

While abstraction redefines transactions, Fuelet Wallet is redesigning account security. Picture this: managing your cryptocurrency as seamlessly as your everyday bank account but with the robust fort of Web3 security. But wait, isn't the seed phrase the bedrock of crypto security?

Well, seed phrases, although foundational, have their own Achilles' heel. A misplaced note, a sneaky camera shot, or a malevolent app can compromise these sacred words. The Fuelet Wallet offers a refreshing solution: seedless account security.

Imagine backing up your seed phrase in your iCloud or Google Drive, courtesy of Fuelet's Cloud Backup. While centralized, it certainly bypasses the dangers of handling and storing seed phrases. And if you're a tech savant with an iPhone, rejoice! Fuelet Wallet is set to transform your device into a hardware wallet, locking your keys in an impenetrable fortress called the Secure Enclave.

Still, the innovation doesn't stop there. The concept of social recovery dials up security, enabling users to recover wallets without seed phrases. Think of guardians - trusted entities who can help you retrieve access. Even your iPhone can serve as a guardian! A safety net of sorts, ensuring you always have access to your precious crypto.

3 - The Road Ahead: Account Abstraction for Dapps

This technological metamorphosis isn't limited to core functions. With the flexibility account abstraction offers, developers can craft applications that blend Web2's user-friendliness with Web3's security. Atomic swaps, order book exchanges, web3auth, and gas fee payments for others are just a few wonders awaiting the decentralization era.

Conclusion: Charting New Horizons with Fuel

The future of crypto is here, and it's personalized, secure, and user-centric. With account abstraction's fine-tuned transaction capabilities and Fuelet Wallet's robust yet user-friendly security measures, we're on the cusp of a new era. An era where managing digital assets isn't just secure but also intuitively simple.

Masterchain

Acting as the backbone of the Venom blockchain, the masterchain is a layer-0 chain that facilitates communication and coordination among the workchains, shardchains, and accounts. It carries the responsibility for message routing, maintaining the network configuration, and retaining information about validators, their stakes, and election rounds.

The Masterchain is also tasked with the distribution of the current shard configuration and the latest block hashes of each corresponding shardchain. A unique set of validators, with the highest stakes, are charged with the generation of new masterchain blocks.

Workchains

Workchains represent specialized layer-1 blockchains, safeguarded by the global validators set. Their connection to the masterchain grants them access to the masterchain's security, with the masterchain validators' efforts forming a protective shield around them.

The design of workchains allows for customizability to cater to the specific needs of the applications they host. Developers have complete control over commissions and emission schemes within their workchains, establishing the Venom Blockchain as a heterogeneous platform.

Basechain

At the time of launch, the Venom blockchain consists of two networks: the Masterchain and the Basechain. The Basechain serves as the initial layer-1 workchain for end-users, hosting dApps and providing a platform for the execution of smart contracts.

Workchain's Interoperability

The interoperability of workchains within the Venom blockchain is facilitated through a native cross-chain communication protocol. This protocol enables trustless interactions between workchains, negating the need for third-party bridges or intermediaries.

Shardchain

The Venom blockchain utilizes shardchains, smaller slices of a blockchain state, to execute computations for a specific subset of accounts. Initially, all transactions are processed by one group of validators belonging to a shardchain. However, as the volume of transactions increases, the network triggers a split event that divides the shardchain into multiple shards. Conversely, if the network load decreases, a merge event can be triggered to combine the shardchains back into a single entity.

Dynamic Sharding

The Dynamic Sharding Protocol, a key feature of the Venom blockchain, enables the network to dynamically adjust the number and size of shards to accommodate the current load.

Split and Merge Events

Split events, announced several blocks in advance, trigger when the shardchain blocks are at least 90% full. The split is then propagated to the masterchain block, updating the shard configuration of the network.

On the other hand, merge events are triggered when the sum of the sizes of the two blocks of sibling shardchains does not exceed 60% of the maximal block size. The system then combines the blocks and transactions from each of the two sibling shardchains to create a new state for the merged shardchain.

With its unique architecture, the Venom blockchain ensures a robust, scalable, and secure platform that seamlessly caters to the needs of its users.

Ever wondered what makes a crypto network stand tall against data breaches and cyber-attacks? Here's your chance to deep-dive into the nuances of network security with Nillion's Information-Theoretic Security (ITS).

We live in a world where encryption isn't always enough. Hackers can potentially decrypt sensitive data by leveraging computational power. But, in a twist to the usual narrative, Nillion's ITS offers cryptanalytically unbreakable security. This means that hackers, despite their impressive computational capabilities, simply can't hack the system.

So, let's dissect this a bit further.

Embracing Unbreakable Security: The ITS Approach

With Nillion's ITS, the key is in the shares of the blinding factor. If T+1 shares can reconstruct this factor, a hacker breaking into T or fewer NMC Nodes will not have enough information to crack the secret. This shields the network against large coordinated attacks (think Sybil attacks), making hacking practically impossible at a network scale. But what about individual data? Could that still be hacked?

Countering Impersonation Attacks: The Role of Multi-Factor Authentication

Yes, an individual's data could be targeted with a front door attack, aka impersonation. A bad actor could impersonate someone else by acquiring their password. This is where Nillion steps up with Multi-Factor Authentication (MFA). A user's MFA could be a combination of a password, biometrics, geographical location, and more, making impersonation significantly more challenging. And what about backdoor attacks?

The Unlikelihood of Successful Backdoor Attacks

Backdoor attacks, while extremely unlikely, are theoretically possible. They hinge on NMC nodes gaining access to the input data. But here's the catch: this requires nodes to identify and obtain the blinding factors from all full nodes, an incredibly complex feat. Given the ITS nature of the network, it's nearly impossible for an attacker to meaningfully conduct a backdoor attack on Nillion.

Ensuring Authorized Access: The Role of Dealer Nodes

Concerned about an attacker setting up a result node to pull all private data out of the system? Fear not. The dealer nodes in Nillion have the power to authorize who can be a result node for specific data sets. An attacker not designated for certain data wouldn't have the required authorization to request the data.

Passive vs Active Adversaries: Understanding the Difference

Nillion's network must be secure against two types of adversaries: passive and active. Passive adversaries stick to the protocol while trying to uncover confidential information. Active adversaries, on the other hand, are willing to deviate from the protocol, providing inaccurate or delayed computational outputs. To combat active adversaries, Nillion employs error correction and message authentication codes (MACs), ensuring result nodes can detect any deviation.

Byzantine vs Broadcast Setup: Two Sides of Network Security

To further secure its network, Nillion has the option between a Byzantine setup, offering security even if less than a third of the nodes are bad actors, and a Broadcast setup, which provides more significant security but risks secrets not being reconstructed if too many nodes exit the network.

Can Firewall Attacks Compromise Nillion?

A firewall, designed to block unwanted traffic, could theoretically be used to prevent nodes from communicating, making information reconstruction impossible. However, Nillion's Byzantine and Broadcast setups provide robust protection against such attacks, making them highly improbable. In the ever-evolving world of cyber-security, Nillion stands as a paragon of network protection. Its ITS approach, coupled with a multi-faceted security setup, ensures the network remains impervious to both brute force attacks and sophisticated hacking attempts. Stay tuned to this space as we continue to explore and unravel the marvels of cryptography in our daily lives!

While Filecoin has made strides in public data storage, it falls short in offering data security and versatility that Nillion provides. Nillion's advanced technology enables a wide range of applications, including decentralized computation, authentication, and key management, that is not possible with Filecoin's current offerings.

When compared to Arweave, Nillion excels in providing permanent, private data storage while maintaining GDPR compliance and fast data processing based on NMC. Although Arweave's block weave technology is designed for efficient, impermanent data storage, it lacks privacy, leaving data exposed.

Qredo's decentralized custody and cross-chain interoperability, though impressive, are limited in scope compared to Nillion. Nillion's NMC technology allows users to enjoy complex transactions across chains, multi-chain wallets, private smart contracts, and many more advanced features.

Privacy-focused blockchains like ZCash and Monero offer valuable features but suffer from scalability problems and auditability concerns. Instead of competing with these blockchains, Nillion seeks to enhance them by providing improved decentralized processing with privacy as an added benefit.

Secret Network's privacy-preserving blockchain relies on trusted execution environments (TEEs), which pose trust issues and potential security flaws. Nillion, on the other hand, guarantees privacy through its Information-Theoretic Security (ITS) and offers a comprehensive range of features that make it a more reliable and versatile choice.

Lastly, Mina's lightweight blockchain is innovative, but its zk-SNARKs technology comes at a high computational cost, limiting scalability. Nillion overcomes this challenge by offering a highly secure and scalable solution through its NMC protocol.

In conclusion, Nillion's unmatched combination of security, versatility, and scalability sets it apart from competitors in the decentralized web space. Its innovative approach to addressing the limitations of other decentralized networks positions Nillion as the top choice for the future of web3 applications.

1 - Information-Theoretic Security (ITS): Unbreakable Encryption

The ITS utilized by Nillion offers cryptoanalytically unbreakable security. By distributing T+1 shares to reconstruct a blinding factor, hackers attempting to access T or less NMC Nodes will not have enough information to uncover a secret, regardless of their computational power. This practically eliminates the possibility of a large-scale coordinated attack to unveil sensitive data, making the network cryptoanalytically unbreakable.

2 - Multi-Factor Authentication (MFA): Shielding Against Impersonation

Nillion employs MFA to protect users from front door attacks, such as impersonation. Users can set various forms of MFA, including passwords, biometrics, and geographic location. The option to require multi-signature MFAs from multiple individuals further reduces the risk of impersonation, as authentication from more than one person is needed to access the data. This ensures different degrees of MFA security, depending on the sensitivity and value of the data stored in Nillion.

3 - Defending Against Passive and Active Adversaries

Nillion is designed to protect against both passive and active adversaries. Passive adversaries are malicious nodes that follow the protocol while attempting to uncover confidential data. Nillion's Information-Theoretic Secure nature prevents any individual node from having enough information to unmask or reconstruct the data it partially holds, providing security against passive adversaries.

Active adversaries, on the other hand, deviate from the protocol and provide incorrect answers to computations. Nillion combats this issue by using error correction and message authentication codes (MACs) to detect when NMC nodes become active adversaries. As a result, the network remains secure and functional as long as less than ⅓ of the nodes are malicious.

4 - Byzantine and Broadcast Setups: Balancing Security and Redundancy

Nillion offers two information security setups: Byzantine and Broadcast. The Byzantine setup provides network security with less than ⅓ of the nodes being bad actors and offers higher redundancy. The Broadcast setup, however, requires only ½ of the nodes to be hostile for a successful coordinated attack, providing a higher security level but posing a greater risk if too many nodes leave the network.

5 - Firewall Attacks: Assessing Improbability and Countermeasures

Firewall attacks, while highly improbable, could potentially prevent nodes from successfully communicating with each other. Nillion has the flexibility to choose between Byzantine and Broadcast setups to mitigate firewall attack risks. The choice depends on whether to prioritize less security but account for firewalls or opt for more security without considering firewall attacks.

As you already got, Nillion's advanced security features, such as Information-Theoretic Security, Multi-Factor Authentication, and robust defense mechanisms against passive and active adversaries, make it an ideal solution for protecting sensitive data in the digital realm. The choice between Byzantine and Broadcast setups offers the flexibility to balance security and redundancy based on specific needs. By embracing Nillion's cutting-edge security technology, users can confidently navigate the world of digital assets with peace of mind.

Compared to Partisia, a permissioned blockchain with limited block space, Nillion stands out as a permissionless network with unlimited scalability. Its computation can be done in plaintext-speed, avoiding the bottleneck issues faced by other platforms like Partisia.

When it comes to ARPA, Nillion's NMC technology is significantly faster and more widely applicable for computations, regardless of their complexity. It provides the first commercially viable MPC public network, offering a greater range of capabilities than ARPA's traditional MPC constraints.

In comparison to THORChain and Chainflip, which focus primarily on cross-chain exchanges, Nillion's NMC technology enables offerings beyond just exchanges. Nillion can facilitate private data storage with ITS, interoperability among blockchains, off-chain processing, and multi-chain wallets.

Fireblocks, on the other hand, focuses entirely on custody and uses traditional MPC primarily for asset storage. In contrast, Nillion is a public permissionless network that leverages MPC technology for both data storage and processing, enabling a greater range of applications and possibilities.

Keep and Gnosis, which offer privacy solutions for sensitive user data, are limited in their applications. Nillion, as a Meta Layer, provides decentralized data storage and processing for blockchains, enabling groundbreaking use-cases ranging from interoperability to multi-chain wallets.

Lastly, when compared to Synapse and IPFS, Nillion goes beyond just providing private key security or peer-to-peer data storage. Its secure processing layer for web3 enables a wide range of applications, from secure ITS data storage and private smart contract compute to other advanced use-cases.

In summary, Nillion's innovative NMC technology positions it as a leader in the decentralized web space, offering a secure processing layer with unprecedented speed, scalability, and versatility. By overcoming the limitations of its competitors, Nillion is poised to revolutionize the way we interact with the digital world.

The NIL Token: The Game Changer

Get ready for the NIL token, Nillion's native utility token, leveraging Ethereum's ERC-20 standard. This token is the backbone of Nillion's network governance and plays a pivotal role in accessing the network, aligning economic incentives, and ensuring node cooperation. Buckle up as we take you on a journey through the various advantages of NIL tokens, including the Node Staking Mechanics and the Node Self-Governance System.

Node Staking Mechanics: Unleashing the Power of Incentives

In the Nillion Network, staking serves as the driving force for maintaining data security and motivating nodes to commit to network excellence. Nodes are required to stake NIL tokens to participate in the network, store particles, and run calculations. The nilDAO plays a vital role in determining the minimum staking requirement for nodes, creating an ecosystem that rewards good behavior and deters bad actors.

Witness how nodes that fail to meet operational requirements face the consequences of slashing, and forfeiting their staking deposits. Nodes that don't maintain the minimum staking threshold lose the ability to participate in network functions or store network data until the minimum staking deposit is restored.

Node Self-Governance System: Shaping the Future of Decentralized Networks

The Node Self-Governance System is a groundbreaking component of the Nillion ecosystem. It ensures that nodes maintain top-notch performance and integrity within the network. Under the watchful eye of the nilDAO, this system combines on-network and off-network information to deliver a comprehensive representation of each node's contribution to network integrity and performance.

Dive into the world of Node Health Scores (NHS) and DAO Support Scores (DSS) that form the core of this system. Understand how the Node Health Factors and DAO Support Factors contribute to these scores, as clearly outlined by the nilDAO.

Node Health Factors and DAO Support Factors: The Building Blocks

Node Health Factors, such as node uptime, length of time on the network, number of successful calculations performed, error rate, slashings, and response times, play a crucial role in determining a node's NHS. Staking by node operators also contributes to a node's NHS.

DAO Support Factors, the additional criteria for Full Nodes, assess the technical diversity and external reputation of a node operator, ensuring sufficient decentralization and preventing centralized points of failure on the network.

The Nillion Token, NIL, is transforming the landscape of decentralized governance. With the power of Node Staking Mechanics and the Node Self-Governance System, the Nillion Network is well-equipped to disincentivize malicious actors and protect against attacks, providing users with a reliable, performant, and robust permissionless network.

The Basics of NMC Network

An NMC network consists of three main types of nodes:

1. Dealer Nodes: These nodes transform confidential inputs into particles and distribute them across the NMC Nodes. Dealer Nodes can be individuals using their mobile devices or corporations using company servers.

2. NMC Nodes: These nodes store the particles provided by Dealer Nodes and perform NMC computations on them.

3. Result Nodes: These nodes reconstruct the results from a finished NMC computation.

How Does NMC Work?

NMC operates in the arithmetic setting running Multi-Party Programs (MPPs). The goal is to jointly compute the result from evaluating an arithmetic function f over a set of secret input values without revealing them. To achieve this, NMC consists of four main steps:

1. Pre-Processing: NMC Nodes run a pre-processing step to generate shares of the blinding factors used by the OTM cryptographic primitive. This step can be done hours, days, or even months before the actual computations.

2. Particle Distribution: Each Dealer Node applies an ITS OTM to hide each private input using different blinding factors, creating particles. The Dealer Nodes then broadcast their particles to the network.

3. Computation: NMC Nodes perform local multiplication and addition operations on their particles as dictated by the arithmetic function that needs to be evaluated. This step requires no inter-node communication, allowing for efficient parallel processing.

4. Result Reconstruction: Each NMC Node sends its particle and blinding factor shares to one or several Result Nodes. These Result Nodes run NMC’s Reconstruction Mechanism to obtain the output of the function that was jointly evaluated without revealing the computational inputs.

The Future of Confidential Computations

NMC's innovative approach to confidential computations has the potential to revolutionize industries that require secure data processing. By leveraging the power of decentralized networks and enabling computations at plaintext speed, NMC paves the way for a new era in privacy-preserving technologies.

In our next post, we'll dive deeper into the practical applications of NMC and explore how this groundbreaking technology can be implemented in various sectors. Stay tuned!

Act One lays the groundwork, traversing the landscape of standard encryption and SMPC, and finally introducing NMC - the star of our show. Act Two delves into NMC's stellar qualities, exploring its performance, decentralization, and security attributes, brilliantly addressing the blockchain trilemma. Act Three brings it all together, showcasing NMC's exceptional processing capabilities.

1. Encryption and Information-Theoretic Security: Nillion uses Information-Theoretic Security (ITS) to ensure the strongest possible security for data processing. ITS is unbreakable even with unlimited computing resources, making it quantum-safe and superior to widely-deployed encryption and Zero-Knowledge Proof (ZKP) technologies. Unlike encryption, Nillion's data can be transferred, stored, and processed while being kept confidential and private.

2. Comparing ZKP, SMPC, and NMC: ZKP is a popular cryptographic primitive used in blockchain technology for preserving privacy. However, it can't transfer, store, or process data while preserving confidentiality. Secure Multi-Party Computation (SMPC) allows multiple parties to store and process data securely but suffers from scalability issues due to inter-node messaging. NMC solves these problems by offering a decentralized, private, performant, ITS, and the versatile public network (Table 1).

As the curtain rises on Act One, we begin by scrutinizing encryption, the backbone of security in modern systems. We then introduce Information-Theoretic Security (ITS) as a game-changing alternative, opening the door to a world of advanced cryptographic protocols. SMPC protocols, such as SPDZ or BGW, demonstrate the potential of ITS but stumble when it comes to scalability. This is where NMC shines, offering a scalable, ITS-based solution that performs on par with plaintext centralized processing.

In Act Two, we examine NMC's theoretical performance, revealing its potential to outpace SMPC by orders of magnitude. We then explore how NMC can revolutionize decentralized trustless networks, and finally, unveil the main security features that make this protocol a fortress of data protection.

Act Three culminates with a deep dive into NMC's processing capabilities, illustrating how this innovative technology can be harnessed by developers to create a new era of secure, decentralized applications.

As you embark on this journey with us, you'll discover how Nillion's NMC protocol has the power to revolutionize the way we store, process, and secure information, challenging the very foundations of current encryption-based systems. Get ready for a thrilling exploration of a technology that has the potential to shape the future of decentralized computing.

Accessing the Network

Users must pay network nodes using NIL tokens to carry out core transfer, storage, and computational functions. Once the request is processed, network participants receive rewards. The cost of using Nillion services depends on factors such as computational complexity, storage requirements, and the number of nodes involved.

Node Staking Mechanics

Nillion requires nodes to stake NIL tokens to participate in the network, store particles, and run calculations. Staking ensures that nodes have a financial incentive to behave correctly and increases the cost of an attack by malicious actors. The minimum staking requirement is determined by nilDAO, the decentralized autonomous organization (DAO) delegated authority over network governance. Full Nodes have a higher minimum staking requirement than Light Nodes because of their enhanced role in the network.

Nodes that fail to meet the minimum staking threshold or fail to meet operational requirements will be subject to slashing, the confiscation of staking deposits. Slashing is performed automatically by the network.

Node Self-Governance System

The Node Self-Governance System is a vital part of Nillion's larger network governance structure. The system is monitored by nilDAO and combines on-network and off-network information to create a holistic representation of each node's contribution to network integrity and performance. Nodes are assigned a Node Health Score (NHS) and a DAO Support Score (DSS), if applicable. All nodes receive an NHS, while only Full Nodes receive a DSS. The NHS and DSS are publicly available on the Node Leaderboard. Users can choose to use nodes with the highest NHS or select nodes with specific NHS and DSS levels.

The Node Self-Governance System creates a financial incentive for node operators to achieve a high NHS, which results in more particles being stored on the node and more participation in network functions. Over time, this increases the robustness of the Nillion Network, as nodes that do not maintain high performance are disincentivized from continuing to participate in the network. The NHS is based on Node Health Factors, while the DSS is based on DAO Support Factors. All factors and their impacts on NHS and DSS are clearly outlined for node operators by nilDAO.

Governance and Future

NIL tokens play a vital role in Nillion's governance through nilDAO, which is formed upon the public launch of the NIL token. nilDAO is delegated authority over specific aspects of network governance and will play an increasing role in governance until it becomes the only governing body of the network.

The Nillion Network comprises three main layers: the Infrastructure Layer, NMC Layer, and Service Layer. The Infrastructure Layer offers basic decentralized network and storage services. It builds on a Distributed Hash Table (DHT) and a peer-to-peer network that is decentralized, resilient, and supports secure sharing of data among nodes.

The NMC Layer is where Nillion's proprietary protocols, 2-NMC and D-NMC, are implemented. These protocols allow Multi-Party Programs to be executed without any message exchange during the computation step, enabling secure decentralized computations. The NMC Layer offers core capabilities to developers through an SDK, such as transfer, store, and compute.

The Service Layer builds on top of NMC to provide additional services to the developer community. It offers high-level programming languages such as Nada and supports other languages such as Solidity. The Service Layer provides several core services, including authentication, key management, enrollment, and decentralized voting.

The Service Layer will also be extended by the developer community to build products and applications. Future services may include machine learning, data analytics, and identity management.

Nillion is a permissionless network that supports two types of NMC Nodes: Light Nodes and Full Nodes. The network is resilient against Sybil attacks, bribery, and collusion between nodes, while remaining permissionless. Node composition prevents these attacks, and the network's security is further ensured by the NIL token. The NIL token plays a crucial role in the Nillion Network, providing node incentives, staking, network security, and decentralized governance.

In conclusion, the Nillion Network offers a secure and decentralized architecture for the transfer, storage, and computation of sensitive data. It provides a comprehensive set of services to the developer community, enabling them to build secure and decentralized applications.

So let’s talk about ZK and Nillion

Firstly you need to know what ZK is

Zero-knowledge(ZK) technology is a type of technology that allows a person (or computer system) to prove that they possess certain information, without actually revealing the information itself. This can be useful in situations where it is important to confirm that someone has certain knowledge or credentials, but where it is not necessary or desirable to reveal the details of that knowledge.

For example, imagine that Alice wants to prove to Bob that she knows the secret password to a secure website, without actually telling Bob what the password is. Alice could use zero-knowledge technology to create a “proof” that she knows the password, which Bob could verify without learning the password itself. This could be useful in situations where the password is sensitive and Alice wants to keep it confidential.

In a more technical sense, zero-knowledge technology involves using complex mathematical algorithms to create “proofs” that can be verified by other parties, without revealing the actual information being proven. This can be useful in a variety of contexts, including cryptography, cybersecurity, and other fields where the confidentiality of information is important.

What’s Nillion brings as ZK-roll up solution?

Nillion allows nodes in a decentralized network to work in a unique, non-blockchain, way.

While Nillion represents a revolutionary leap from a predecessor technology known as Secure Multi-Party Computation (SMPC), unlike SMPC, network nodes do not have to communicate with one another. Unlike blockchain, nodes do not run immutable ledgers designed to store transaction data.

Instead, new Nillion technology, called Nil Message Compute (NMC), is purpose built for decentralized secure storage and computation and thus opens up new use cases (on the Nillion native network), while also enhancing existing blockchains.

The key thing is Nillion is a NMC, so let’s talk more about it

The NMC protocol powers Nillion’s decentralized and scalable public utility for the secure and fast information processing. In this section, we go through background context and then progressively explain the different elements comprising the NMC protocol.

So basically Nillion providing us a new option to process ZK transactions

From Zero-Knowledge Proof to Secure Multi-Party Computation to Nil Message Compute

Let’s briefly compare ZKP, SMPC, and NMC(Nil Message Compute).

ZKP is currently the main cryptographic primitive providing privacy to blockchain technology, and it underpins many significant privacy tokens and private smart contract enabled protocols. ZKP allows a node (the “prover”) to prove to another node (the “verifier”) that a given statement based on the data they hold is true without sharing this data. Each cryptographic primitive is built for a different purpose and serves different goals.

SMPC is a decentralized protocol that allows multiple parties to collaboratively store and process data while guaranteeing data confidentiality. In addition, some SMPC protocols are ITS (such as BGW [14], GMW [4], and SPDZ [15]). However, the main problem with SMPC is its scalability. Processing confidential data in an SMPC network requires the nodes to exchange a large number of messages when the computation is not trivial. This can easily lead to execution times that take hours. This lack of scalability has been the main factor preventing SMPC from use in many real-world applications.

NMC is the cryptographic foundation underlying Nillion, as it is better suited than ZKP or SMPC for the decentralized storage and processing of confidential data. NMC allows for the implementation of a decentralized, private, performant, ITS, and versatile public network, enabling a range of interesting new use cases

There are a lot more nice things Nillion brings to us you can find details in the Nillion WhitePaper.

From my point of view, I can say that this project desires your attention and can be a leading project of in ZK sector for the coming years.

As a user, you can follow Twitter & Discord (links in the head of the page), watch the project, and take part in community events while waiting for Nillion to go Live

This is where zkLink comes in. zkLink is a DeFi protocol that aims to solve the problem of liquidity segregation and incompatibility between different blockchain networks. It uses cutting-edge technology, including Zero Knowledge technology and an Oracle network, to provide a secure and efficient way to move assets between different chains.

One of the key features of zkLink is its “one-click” cross-chain trading tool. This tool allows users to trade between different blockchain networks with just a single click, while still being able to benefit from liquidity pools on different chains. This makes the process of trading between different blockchain networks faster, easier, and more secure.

Behind the scenes, zkLink aggregates liquidity from other DEXs to ensure that users get the best exchange rates and the most cost-effective routes for their trades. This means that any token listed on a local DEX can be exchanged globally, without the need to exchange their source tokens to a zkLink supported token list in advance. This saves users time and money, and reduces the volatility of potential sudden price changes of the involved token pairs.

Another important aspect of zkLink is its unique withdrawal system. One of the biggest challenges for any Layer2 protocol is the trade-off between assets security and long waiting times for withdrawals from Layer2 back to Layer1. zkLink addresses this problem by introducing the concept of “brokers”. When a withdrawal request is made, the optimal broker will then initiate a transaction from its Layer1 wallet on the target chain to the trader’s, via a zkLink smart contract deployed on Layer1 for data storage. This process takes only one block interval of the target chain, meaning that traders will receive their target tokens almost immediately.

Overall, zkLink aims to improve the user experience and make it easier for users to access liquidity on different blockchain networks. With its cutting-edge technology and unique features, zkLink is a powerful tool for traders and crypto holders looking to navigate the complex and ever-changing world of cryptocurrency.
