As humans, we have been consistently evolving. weve constantly develop more accessible alternatives to make life “Easy and comfy”. We came from mailing at the post office and waiting for days to get a response, to sending electronic mail powered by the internet and many other advancements.

It takes around 3-4 days to settle a transaction between banks in the US. and  It can take up to 3-4 weeks to settle a transaction from the US to Nigeria.

But the 21st-century businessman wants an infrastructure that allows him to settle transactions as fast and as easily as possible. Peer-to-peer transactions were the trend in the past, and it looks like we might be going back to those days but this time it will happen On-Chain.

What is Bitcoin?

Bitcoin is a decentralized digital currency. It was created in 2009 by an anonymous person or group of people using the pseudonym Satoshi Nakamoto. It operates on a technology called blockchain, which is a distributed immutable ledger that records all Bitcoin transactions.

Bitcoin has gained significant attention and significance in the financial world due to its potential to revolutionize the way we make payments. It offers several advantages over traditional fiat currencies and has the potential to serve as the world’s reserve currency and best payment alternative.

Transaction settlement on the Bitcoin network

Bitcoin settles transactions through a decentralized peer-to-peer network. When a transaction is initiated, it is broadcasted to all network participants.

Nodes validate the transaction and once confirmed, it is grouped with the others into a block. Miners compete to solve a puzzle and add the block to the blockchain. Once added, the transaction is settled.

The speed of settlement depends on factors like network congestion and fees. No middlemen are involved, ensuring speedy and direct transactions.

A step-by-step approach to how Bitcoin transactions are settled:

• A user initiates a Bitcoin transaction.

• The transaction is broadcasted to the Bitcoin network.

• Miners (which are computers) compete to add the transaction to a block.

• The block is verified by the network.

• The transaction is added to the blockchain.

• The transaction is settled and the recipient receives his bitcoins.

  note that these transactions happen in a few seconds or minutes without an intermediary and cannot be stopped or censored.

Problems facing Bitcoin as a Means of payment

Price Volatility: Bitcoin is known for its extreme price volatility. The value of Bitcoin can fluctuate significantly within short periods, making it challenging to determine its precise purchasing power. This volatility poses a risk for both merchants and consumers, as the value of Bitcoin at the time of a transaction may differ greatly from its value when received or spent.

Scalability: Bitcoin's blockchain has scalability limitations, meaning it can handle only a limited number of transactions per second. During peak times, transaction confirmation times can be slow, resulting in delays and higher transaction fees. The scalability challenge hampers Bitcoin's ability to serve as a widely adopted payment system, especially during periods of high transaction volume.

Regulatory Uncertainties: The regulatory landscape for Bitcoin is complex and varies across different jurisdictions. Governments worldwide are still grappling with how to regulate cryptocurrencies, including Bitcoin. The lack of clear and consistent regulations can create uncertainties for businesses and consumers, potentially hindering the widespread adoption of Bitcoin as a means of payment.

User Experience and Technical Complexity: Bitcoin transactions can be complex for non-technical users, requiring an understanding of wallet addresses and seed phrases. The user experience of Bitcoin wallets and payment interfaces may vary, leading to potential usability challenges. The technical creates an adoption barrier for individuals less familiar with cryptocurrency technology.

Is Bitcoin sustainable as a peer-peer payment network?

Although Bitcoin has steadily gained popularity and acceptance over the years due to its ability to scale several financial challenges. The minds of the public especially none crypto users have continued to wonder;

• What could the possible future of Bitcoin be?

• What will regulators do about it?

• Will the network ever fail?

Important upgrades have to be made to further strengthen the network, make it suitable for growing demand, and clear the doubts in the minds of potential users. There has recently been a lot of innovation to help Bitcoin become the currency of the future.

Here are a few Technological Upgrades On bitcoin

Lightning Network:

One significant innovation that has increased the usage of Bitcoin globally is the Lightning Network. This layer-two scaling solution addresses the network's scalability issue by enabling faster and cheaper transactions.

By leveraging payment channels, the Lightning Network facilitates instant transactions with reduced fees, effectively increasing Bitcoin's potential for everyday use. The development and growing adoption of this technology underscore the belief that Bitcoin can become a viable medium of exchange for microtransactions and everyday purchases.

Taproot upgrade

The most significant upgrade for Bitcoin in the past four years is the recently implemented Taproot upgrade. This groundbreaking update introduces the ability to batch multiple signatures and transactions together, resulting in a more efficient and expedited verification process for transactions on the Bitcoin network.

Furthermore, Taproot incorporates a mechanism that blends transactions with both single and multiple signatures, enhancing privacy and making it considerably more challenging to identify specific transaction inputs within Bitcoin's blockchain. By streamlining transaction verification and bolstering privacy measures, Taproot holds the potential to facilitate the scalability of the Bitcoin network, by accommodating a higher volume of transactions.

Decentralized finance on Bitcoin

While Ethereum has traditionally been the dominant platform for decentralized finance (DeFi), recent innovations have brought DeFi capabilities to the Bitcoin network. Projects such as Rootstock (RSK) and the Liquid Network offer smart contract functionality on top of Bitcoin, enabling the creation of decentralized applications, that will facilitate the building and usage of Decentralized finance on Bitcoin.

The introduction of  DeFi on Bitcoin goes to show that Bitcoin's secure and robust network can be leveraged for a broader range of financial applications, like borrowing, lending, staking, and storing of data.

Early this year, the BRC20 token standard an experimental token standard on the bitcoin network became a trend, alongside ordinals which are bitcoin NFTs.

Data from Brc-20.io shows that there are currently 37,200 brc20 with a market cap of over $1 billion. Goes to show that people believe so much in the innovations on the bitcoin network and are ready to continuously support the ecosystem

Institutional and General Interest in Bitcoin

In recent years, we have witnessed a surge in institutional interest and adoption of Bitcoin. we have seen big institutional fund managers including BlackRock with over $9 trillion in assets apply to offer bitcoin spot etfs to their clients.

Renowned companies, including Tesla, MicroStrategy, and Square, have also allocated significant portions of their treasury reserves to Bitcoin, signaling confidence in its long-term value.

The interest of the general public in Bitcoin has witnessed an impressive upward trajectory, this is evident in the continuous increase in the number of active addresses.

Data from Glassnode shows that Over 44.15 million unique addresses have a non-zero Bitcoin balance. On May 13th, the number of Bitcoin wallet addresses holding one full BTC or more surpassed one million, according to Glassnode data.

This signifies that the number of people that use Bitcoin is increasing by the day. As people worldwide realize the benefits and potential of Bitcoin, they are increasingly embracing it as a viable financial instrument.

Financial Inclusion and bitcoin

Bitcoin offers accessibility to anyone with an internet connection, enabling financial inclusion for the unbanked population. This inclusive nature of Bitcoin has attracted users from all corners of the globe.

Technological Advancements have also contributed immensely to its growth and usage. User-friendly interfaces, improved security measures, and enhanced accessibility has lowered the barriers to onboarding new users.

Bitcoin Stands Tall

Bitcoin's relentless evolution and constant upgrades are testaments to its robustness and potential as the payment system of the future. With an unyielding commitment to scalability and security, Bitcoin will solidify its position as a global peer-to-peer payment network.

Additionally, the ongoing advancements in environmental sustainability, with the integration of renewable energy sources and the adoption of greener mining practices, further reinforce Bitcoin's viability as a sustainable payment system.

As it continues to evolve, Bitcoin stands poised to revolutionize the way we transact and pave the way for a more inclusive financial future

Crypto and blockchain technology has evolved from an idea to a global phenomenon. Since the introduction of Bitcoin in 2009, cryptocurrencies have gained widespread attention, fostering innovation and challenging traditional financial systems.

Although the concept of decentralization and anonymity initially appealed to early adopters, concerns about fraud, market manipulation, and consumer protection have prompted the need for regulatory measures that will a guideline for the operations of this new technology

Introduction to cryptocurrency regulation

Regulation represents the collective efforts of governments and other regulatory bodies to establish guidelines, laws, and frameworks that will govern the creation, distribution, trading, and use of cryptocurrencies.

The goal is to support and encourage innovation whilst safeguarding against potential risks such as money laundering, fraud, and market manipulation.

As cryptocurrencies revolutionize how we handle money, governments and regulators are working to create rules and frameworks to ensure their safe and responsible use.

Crypto regulation aims to strike a balance between fostering innovation and protecting against risks like fraud and money laundering. It's a global challenge that requires collaboration if we must create a friendly environment where innovation can thrive.

TYPES OF CRYPTO REGULATION

Securities Regulations: Some countries treat certain cryptocurrencies or initial coin offerings (ICOs) as securities and regulate them accordingly. This means that they must comply with securities laws, including registration requirements, disclosure obligations, and investor protections.

Anti-Money Laundering (AML) and Know Your Customer (KYC) Regulations: Many jurisdictions have implemented AML and KYC regulations to combat illicit activities such as money laundering and terrorist financing. Cryptocurrency exchanges and service providers are often required to verify the identities of their users and report suspicious transactions.

Consumer Protection Regulations: Governments have introduced consumer protection measures to safeguard cryptocurrency users. These regulations mainly focus on issues such as misleading advertisements, fraud prevention, and ensuring transparency in crypto-related transactions.

Taxation Regulations: Tax authorities in several countries have issued guidelines or regulations regarding the taxation of cryptocurrencies. This includes determining the tax treatment of cryptocurrency transactions, capital gains taxes, and reporting requirements.

Licensing and Registration Requirements: Some jurisdictions require cryptocurrency businesses, such as exchanges or wallet providers, to obtain licenses or register with relevant regulatory authorities. These requirements aim to ensure compliance with applicable laws and regulations.

Impact of Regulation on the Crypto Market

Increased investor confidence:

One of the primary benefits of cryptocurrency regulation is the potential to boost investor confidence in the market. Cryptocurrencies have often been associated with high levels of risk and uncertainty due to the lack of regulatory oversight.

By implementing clear regulations and establishing legal frameworks, regulators can provide a sense of security and protection for investors. This, in turn, can attract a broader range of participants, including institutional investors and traditional financial institutions who may have been hesitant to enter the market without proper regulatory safeguards.

Increased investor confidence can lead to greater liquidity, improved market depth, and a more stable investment environment.

Mitigating fraud and scams:

The unregulated nature of the cryptocurrency space has made it susceptible to various fraudulent activities and scams.

Regulatory measures can help mitigate these risks by imposing strict standards on market participants and enforcing compliance with anti-money laundering (AML) and Know Your Customer (KYC) requirements.

By mandating transparent practices and accountability, regulators can discourage fraudulent activities, such as Ponzi schemes, fake ICOs, and market manipulation.

Moreover, regulatory oversight can facilitate the identification and prosecution of bad actors, thus protecting investors from potential losses and fostering a more trustworthy environment for cryptocurrency transactions.

Institutional adoption and mainstream acceptance:

The establishment of clear regulatory frameworks can play a pivotal role in driving institutional adoption of cryptocurrencies.

Institutional investors, such as hedge funds, asset managers, and pension funds, often require regulatory clarity and compliance standards before engaging in any asset class.

Furthermore, regulatory oversight can enhance the perception of cryptocurrencies among the general public and traditional financial institutions, promoting mainstream acceptance and integration of digital assets into existing financial systems.

Challenges and concerns with regulations

Cryptocurrency regulation poses several challenges and concerns, which stem from the unique nature of digital assets and the evolving regulatory landscape. To illustrate these concerns, let's explore real-life analogies and cite situations where they have played out in the past:

Balancing Innovation and regulatory oversight:

Similar to the early days of the internet, cryptocurrencies and blockchain technology are disruptive innovations that have the potential to revolutionize various industries.

Over-regulation can stifle innovation and hinder the development of new technologies and business models. Striking the right balance between fostering innovation and implementing necessary regulatory oversight is crucial.

Regulatory arbitrage and jurisdictional challenges:

Cryptocurrencies operate globally, making it challenging to establish consistent regulations across jurisdictions. This can lead to regulatory arbitrage, where businesses or individuals can exploit regulatory loopholes by moving operations to more lenient jurisdictions.

This has visible from the recent wave of migration of crypto companies from the US to Bermuda who is determined to become the hub of crypto industries.

The absence of global regulatory coordination has created a fragmented landscape, raising concerns about regulatory effectiveness and unfair competition.

Compliance costs and burdens:

Compliance with regulations can be resource-intensive and burdensome, especially for smaller cryptocurrency businesses and startups.

The costs associated with compliance, such as implementing AML/KYC procedures and maintaining regulatory reporting, can disproportionately affect smaller players.

This could create barriers to entry and hinder the participation of innovative startups in the industry.

Evolving regulatory landscape and uncertainty:

The cryptocurrency regulatory landscape is still developing and evolving. Uncertainty about future regulations and their specific requirements can create challenges for businesses and investors.

Rapidly changing regulatory frameworks may necessitate continuous adaptations, causing compliance difficulties and legal uncertainties.

Country-specific Approaches to Cryptocurrency Regulation

It is important to note that different jurisdictions have adopted varying approaches to regulating cryptocurrencies, to reflect the unique legal, economic, and cultural landscapes of each country.

Here, we will explore the regulatory approaches of several notable jurisdictions.

United States:

The United States has taken a multifaceted approach to cryptocurrency regulation. Regulatory bodies such as the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) play a significant role.

The SEC has focused on determining whether certain cryptocurrencies or token offerings qualify as securities, subjecting them to registration requirements. Additionally, the Financial Crimes Enforcement Network (FinCEN) imposes AML and KYC obligations on cryptocurrency businesses.

European Union:

The European Union (EU) has been actively working on harmonizing cryptocurrency regulations across its member states. In 2019, the EU introduced the Fifth Anti-Money Laundering Directive (AMLD5), which extended AML and KYC obligations to cryptocurrency exchanges and custodian wallet providers.

Additionally, the EU is currently developing the Markets in Crypto-assets (MiCA) regulation, aiming to create a comprehensive regulatory framework for cryptocurrencies and stablecoins.

China:

China has taken a relatively strict approach to cryptocurrency regulation. In 2017, the Chinese government imposed a ban on initial coin offerings (ICOs) and prohibited cryptocurrency exchanges within its borders.

However, it is worth noting that China has continued to explore and develop its own central bank digital currency (CBDC), known as the digital yuan or DCEP (Digital Currency Electronic Payment), which is expected to be subject to its own regulatory framework.

EL SALVADOR

El Salvador has made significant strides in embracing cryptocurrencies and becoming the first country to adopt Bitcoin as legal tender. The regulatory structure in El Salvador primarily revolves around the Bitcoin Law, which was passed in June 2021.

Under the Bitcoin Law, the government of El-Salvador recognizes Bitcoin as legal currency alongside the United States dollar, which has been the country's official currency since 2001. This means that businesses are obligated to accept Bitcoin as a form of payment, although individuals have the option to use other currencies if they prefer.

Japan, South Korea, and Switzerland have distinct approaches to cryptocurrency regulation. In Japan, cryptocurrencies like Bitcoin are recognized as legal payment methods, and the Financial Services Agency (FSA) oversees cryptocurrency exchanges with licensing requirements and regular inspections.

South Korea implemented the "Real-Name System" for exchanges, emphasizing AML and KYC procedures.

Switzerland, known for its Crypto Valley, follows a principles-based regulatory framework under the Swiss Financial Market Supervisory Authority (FINMA), prioritizing AML compliance and investor protection while fostering innovation.

These countries showcase a range of approaches, from recognition and regulation to stringent AML measures and flexible frameworks that encourage crypto development.

Regulators and policymakers globally are recognizing the need for collaboration and coordination in regulating cryptocurrencies. Initiatives such as the Financial Action Task Force (FATF) and the International Organization of Securities Commissions (IOSCO) are fostering international cooperation and sharing best practices.

These collaborations aim to develop consistent regulatory standards, combat money laundering, and ensure investor protection across borders. Global regulatory coordination may reduce regulatory arbitrage and provide a more level playing field for market participants.

Recent Regulatory Developments and their impact

SEC actions and guidance in the United States:

The U.S. Securities and Exchange Commission (SEC) has been actively involved in regulating cryptocurrencies. Recent actions and guidance from the SEC have focused on clarifying the regulatory status of digital assets and initial coin offerings (ICOs).

These actions have brought more certainty to the market, allowing compliant projects to thrive while deterring fraudulent activities. The SEC's regulatory stance has influenced investor confidence and shaped the behavior of market participants in the United States.

EU's proposed MiCA regulations:

The European Union's proposed Markets in Crypto-assets (MiCA) regulations aim to establish a comprehensive regulatory framework for cryptocurrencies and stablecoins across member states.

MiCA seeks to harmonize rules regarding issuers, service providers, and custody of crypto-assets. If implemented, MiCA could provide legal clarity, enhance consumer protection, and promote market integrity within the EU.

These regulations may attract more institutional investors and foster innovation in the European crypto market.

Central bank digital currencies (CBDCs):

Several central banks worldwide have been exploring the concept of issuing their own digital currencies. CBDCs are digital representations of fiat currencies, backed by central bank reserves.

The development and potential issuance of CBDCs can have significant regulatory implications. Regulators are assessing the impact on monetary policy, financial stability, privacy, and cross-border transactions.

CBDCs could reshape the financial landscape, affecting traditional banking systems, payments, and the use of other cryptocurrencies.

Global regulatory collaborations and initiatives:

Regulators and policymakers globally are recognizing the need for collaboration and coordination in regulating cryptocurrencies. Initiatives such as the Financial Action Task Force (FATF) and the International Organization of Securities Commissions (IOSCO) are fostering international cooperation and sharing best practices.

These collaborations aim to develop consistent regulatory standards, combat money laundering, and ensure investor protection across borders.

Global regulatory coordination may reduce regulatory arbitrage and provide a more level playing field for market participants.

Effect of Regulation on Decentralization

There are arguments that regulations will remove the originality embedded in the vision of decentralization which is the absence of intermediaries, financial inclusion, and, anonymity. Diluting these elements changes so much and may stifle its development.

But the question remains thus: “To what extent does decentralization grant this financial inclusion and access?

This question owes to the fact that anybody these days can create a project to his name and run off after making some gains. This is possible because players remain anonymous and as a result cannot be held accountable for their actions as it may be difficult to prove who that bad actor was.

Right now it is quite easy to get onboard as a project owner, a validator, etc, but what will it be like after regulations? Will we see a change in things? will participants have to be licensed to be able to create?

This could limit the number of people that are willing to build on-chain, but looking on the brighter side, this may be the ‘green flag’ that attracts only people that are willing to build as opposed to '‘rug pull militants”

Regulation can have both positive and negative effects on decentralization, depending on the specific context and the nature of the regulations implemented.

What do you expect from regulations?

The complexity involved in creating and maintaining a crypto wallet on meta mask or phantom wallet has to be one of the few hurdles a new crypto user has to scale through to begin his journey.

Saving of seed phrases, The risk of losing them or exposing them to malicious actors, and the sole dependence on Ether as the only token for payment of transaction fees, has limited the use of Defi protocols to its full potential. The announcement of an Ethereum improvement plan (EIP) to create a new wallet architecture summarily called smart wallets is the game changer and a catalyst towards massive adoption.

Outline

• Background

• What is ERC-4337

• How does it work?

• What are its core features?

• Can ERC-4337 be a catalyst for adoption?

Background

The Ethereum blockchain was designed to be highly adaptable, enabling developers to build DAPPS directly on the main network. But prior to the integration of any significant new features into the Ethereum platform, a proposal must first be submitted in the form of an Ethereum Improvement Proposal (EIP). EIPs establish various standards, ranging from core protocol specifications to contract and token standards at the application level.

Once approved through on-chain governance, an EIP may be elevated to the status of an Ethereum Request for Comment (ERC). ERC-4337 is the most recent example of a standard deployed on the Ethereum mainnet. While it was originally proposed as EIP-4337 in 2021, it was not authorized to become an ERC until 2023.

What is ERC-4337

ERC-4337 merges two types of accounts, externally owned accounts and contract accounts and unifies them under a single type of account. This will enable features like Social recovery, Multi-signature, Gas abstraction, Custom logic, and interoperability

The architecture of Ethereum wallets has been simplified and made more user-friendly through the implementation of the ERC-4337 wallet standard.

How does ERC-4337 work?

ERC-4337 works through account abstraction that turns user wallets into smart contract accounts

On the Ethereum network, there are two types of accounts with their own unique functionalities. The first type is Externally Owned Accounts (EOAs), which are controlled and owned by users, while the second type is Smart Contract Accounts, which are smart contracts deployed on the network.

 However, existing crypto wallets like MetaMask, which are mostly EOAs, are constrained by the regulations set around them. For instance, private keys are the only means of accessing accounts, and all transactions must be signed. Consequently, wallet setup procedures and private key security measures are often complicated and unfriendly to users. In the event of seed phrase loss, users can lose access to their wallets.

ERC-4337 introduces an easier alternative for new users to join the decentralized world of crypto without having to learn about complicated seed phrases or wallets. Users can use social logins or other methods to create instant wallets on any EVM blockchain using their email, phone number, Google account, or Facebook account.

It also introduces an alternative memepool called "bundlers", with which transactions can be batched and processed off-chain, before being submitted to the main chain as a single transaction. This reduces the load on miners and validators and allows for faster confirmation time.

These bundlers incorporate paymasters to users interact with smart contracts on Ethereum without paying gas fees directly. This way, the user could access various DeFi services on Ethereum without needing ETH or worrying about gas prices.

Core features of ERC-4337

 Social recovery: Currently, when a user loses their private key (which is required to access their Ethereum account), there is no way to recover the account, and any funds stored within it are essentially lost forever. Social recovery aims to address this issue by allowing users to set up a "recovery committee" of trusted individuals who can collectively recover their accounts if they lose their private keys.

 Gas abstraction: Currently, when a transaction is sent on the Ethereum network, the sender must pay a fee in Ether (the network's native cryptocurrency) to cover the cost of processing the transaction. With account abstraction, however, the payment for transaction fees could be made using any token or cryptocurrency, not just Ether. This would allow for greater flexibility for users, as they could use their preferred cryptocurrency to pay for transactions.

 Custom logic: Custom logic refers to the ability for developers to define their own rules and logic for processing transactions, In traditional Ethereum transactions, the rules for processing transactions are hardcoded into the Ethereum Virtual Machine (EVM), which executes smart contracts and processes transactions on the network. However, with account abstraction, developers would be able to define their own transaction processing logic, which could include custom fee structures, validation rules, and other parameters.

Multi-signature: Multi-signature (multi-sig) refers to a type of digital signature scheme that allows multiple parties to jointly sign a transaction. This enables multiple parties to sign off on transactions, For example, a multi-sig smart contract could require two out of three parties to sign off on a transaction before it can be executed. This could be useful for situations where multiple parties need to agree on the use of funds, such as in a business partnership or investment fund.

Interoperability: Account abstraction also allows for interoperability between different blockchains and smart contracts. This enables developers to create more complex and sophisticated applications that can interact with a wider range of assets and accounts, without being limited by the technical constraints of the underlying blockchain.

Imagine a smart contract that needs to execute a function that requires a certain amount of ether to be transferred to a specific address but the account does not have sufficient eth to cover the transaction. Smart accounts or (AA accounts) can interact with any account or asset on the blockchain, and allow it to execute the transaction even if it doesn't have enough ether in its own account.

Can ERC-4337 be a Catalyst for adoption?

A key advantage of ERC-4337 is its capacity to support a range of authentication methods. Users can now use biometric authentication methods such as facial recognition or fingerprint scanning, And traditional Web2 logins such as email or social media. This eliminates the need for users to depend on a custodial service or device for accessing their funds, which enhances the overall security of the system. This innovation offers users greater flexibility in controlling their digital assets.

 According to Ethereum Foundation security researcher Yoav Weiss, 

“The next billion users are not going to write 12 words on a piece of paper. Normal people don’t do that…. We need to give them better usability, they shouldn’t need to think about cryptographic keys.”

 John Rising, the co-founder of Stackup, has opined that an added advantage of account abstraction is that projects can use plain and easily understood language to onboard new users rather than arcane technical terms.

“Because the contract handles the esoteric blockchain stuff, you don’t have to use words like ‘gas’ or ‘nonce’ to accurately describe what’s happening. This is a huge win for crypto adoption and security.”

 Some have however argued that In a few years’ time, with the continuous development of this innovation the new ERC-4337 standard will transform a crypto wallet into something with all the features of a real bank.

It will give users the same features a bank would give (with the exclusion of having to trust a third party). Where someone can always help recover your bank account even if you lose your password. Users who misplace their phone or device can use time-locked social account recovery through a group of trusted friends or even a commercial service.

Since ERC-4337 would feature smart accounts, users can automatically pay bills through their crypto wallets.

Visa's crypto research team recently published a paper discussing how smart accounts (Abstracted accounts) on StarkWare can be used to pay bills automatically from a self-custodial crypto wallet, without relying on a centralized service. Essentially, this means that you could set up your crypto wallet to automatically pay bills like your mortgage or utilities, without having to trust a third-party service.

Despite its benefits, the ERC-4337 standard's increased flexibility also brings a great risk of exploitation. This is due to its reliance on a higher-layer infrastructure, which can introduce new vulnerabilities and dependencies. Furthermore, compatibility issues may arise with existing wallets or applications that do not support the new standard. Finally, using dApps such as bundlers or other third parties may require users to place more trust in these entities with their transactions, which may pose a significant challenge for some users.

Furthermore, ERC-4337 is still an experimental standard that may have unforeseen issues or challenges. However it could be the breakthrough we've needed for ease of use, which would culminate in onboarding a million more users.

What is DEFI

Decentralized finance also called DeFi is a financial system built on blockchain technology to enable individuals to access a wide range of financial services, such as lending, borrowing, and trading, directly from their own devices.

It eliminates the need for intermediaries and empowers anyone with an internet connection to conduct transactions Peer-to-Peer and participate in the global economy.

The Emergence Of Defi

It all began with the emergence of Bitcoin after the financial crisis of 2008. Bitcoin introduced the world to a new kind of digital currency that was decentralized and could be used for secure and transparent transactions without the need for intermediaries.

However, While Bitcoin introduced the world to decentralized digital currency and inspired the development of new DeFi applications, the Bitcoin network was not really designed to support the creation of DApps. Bitcoin's scripting language is limited in functionality, which makes it difficult to build complex applications on the Bitcoin network.

This limitation led to the emergence of the Ethereum network in 2014

Ethereum, being a programmable blockchain, allows developers to create custom Decentralized Apps using smart contracts.

Ethereum has since then become the most popular blockchain platform for building decentralized applications, and it has enabled the creation of many of the most significant DeFi innovations, including decentralized exchanges, lending and borrowing platforms, stablecoins, and more.

ETH’S Contribution to DEFI

Smart Contracts: Ethereum's introduction of smart contracts has been one of its most significant contributions to the crypto and DeFi space. Smart contracts have real-life use cases like self-executing contracts of the terms of the agreement between a buyer and seller directly written into lines of code.

This innovation has also enabled the creation of decentralized applications (DApps) that has allowed financial transactions to happen autonomously without the need for an intermediary. Some popular DApps built on Ethereum include decentralized exchanges like Uniswap, lending platforms like Aave, and gaming applications like Axie Infinity.

Decentralized Autonomous Organizations (DAOs): Ethereum has also enabled the creation of decentralized autonomous organizations (DAOs). A DAO is a decentralized organization that operates through rules encoded as computer programs called smart contracts. One of the most famous DAOs is The DAO, which was launched in 2016 and raised more than $150 million in funding. While The DAO was eventually hacked, it highlighted the potential of DAOs as a new form of organization that can operate without centralized control.

Non-Fungible Tokens (NFTs): Ethereum's support for non-fungible tokens (NFTs) has been another important contribution to the DeFi space. NFTs are unique digital assets that are stored on the blockchain, and they have enabled the creation of new types of decentralized applications, including digital art marketplaces, collectibles, and gaming applications. Some popular NFT marketplaces on Ethereum include OpenSea, Rarible, and SuperRare

Proof of Stake (PoS) Consensus Mechanism: Ethereum's upcoming transition to a proof-of-stake (PoS) consensus mechanism is another significant contribution to the crypto and DeFi space. Currently, Ethereum uses a proof-of-work (PoW) consensus mechanism, which is energy-intensive and has been criticized for its environmental impact. The PoS consensus mechanism aims to address these issues by using staking instead of mining to validate transactions and secure the network.

Decentralized Oracles: Ethereum has enabled the creation of decentralized oracles, which are a crucial component of many DeFi applications. Oracles are a bridge between the blockchain and off-chain data, providing DeFi applications with access to real-world information.

Examples of real-world use cases for oracles can be seen in, Supply chain management, Energy Markets, Gaming, and Insurance payout automation, Some popular decentralized oracle networks on Ethereum include Chainlink, Band Protocol, and Tellor.

BTC VS ETH

Ethereum was not built from Bitcoin but was inspired by its existence and sought to build upon it by offering even greater utility.

Overall, while Bitcoin and Ethereum share some similarities, they are two distinct blockchain networks with different features and capabilities. While Bitcoin has been successful in becoming a widely accepted digital currency, Ethereum's advanced programming capabilities have enabled the creation of a vibrant ecosystem of decentralized applications and digital assets, expanding the possibilities of what can be achieved with blockchain technology.

DEFI on Bitcoin?

With the implementation of the Taproot upgrade on the Bitcoin network, new possibilities have been unlocked, including the ability to build decentralized applications (DApps) on the blockchain. This development is expected to improve the long-term sustainability of the Bitcoin network and accelerate the growth of the DeFi movement on the platform.

Projects like RenVM, Liquid Network, Barger DAO Stacks, and Rootstock are building DEFI infrastructures in the Bitcoin ecosystem. There has also been a recent introduction of bitcoin NFTs called ordinals

DEFI on bitcoin, However, is less approachable than on the Ethereum blockchain and other smart contract platforms.

The question is why?

There has been quite some hype around the zk-rollup innovation— which include zkSync, Scroll, and solutions from Polygon, StarkWare, and Consensys — this is believed to be the long awaited innovation that will completely solve the Ethereum scaling problem.

What are ZK-rollups

ZK rollup is a scaling solution that enables the processing of a large number of transactions off-chain and then committing them to the blockchain in a compressed form. ZK rollup uses zero-knowledge proofs to verify that the off-chain transactions are valid before committing them to the blockchain.

In a ZK rollup, users deposit funds into a smart contract on the main blockchain, which acts as a "rollup" aggregator. Then, transactions are conducted off-chain and bundled together into a single ZK-proof that is submitted to the roll-up aggregator on the main blockchain. The rollup aggregator verifies the proof and updates the state of the smart contract on the main blockchain, reflecting the bundled transactions.

ZK rollups have gained popularity in the Ethereum ecosystem, with several projects currently working on implementing the technology for their dApps.

Firstly, deploying on zk-rollups allows projects to significantly reduce transaction costs, which is a significant barrier to adoption for many users. With the high fees associated with using the Ethereum network, many users are priced out of participating in decentralized finance (DeFi) applications. By leveraging zkSync, projects can reduce transaction costs to “a fraction of a penny”

ZK rollups offer several other benefits apart from scalability and reduced gas fees, the use of ZKPs allows for increased privacy and security of transactions since the details of individual transactions are kept private within the rollup.

Our focus in this work is zkSYNC Era built by matter labs on the Ethereum network

Ethereum, according to the team, is the most decentralized blockchain, capable of bringing sovereignty to billions of people. zkSync Era scales Ethereum’s security and its values of trustlessness, permissionless access, censorship resistance, resiliency through decentralization and community ownership.

Ethereum remains the most widely used blockchain platform for building decentralized applications (dApps) and executing smart contracts. However, the Ethereum network has been facing several scalability challenges that have limited its ability to scale to meet the growing demand for its services.

The primary scalability challenge faced by Ethereum is its limited transaction processing capacity, which is currently limited to about 15 transactions per second (tps). This limitation has resulted in high gas fees and longer confirmation times, making it challenging for developers to build dApps that can scale to meet the needs of a large user base.

What is ZKsync

ZKSync, is a specific implementation of a ZK rollup that is designed to provide a high-performance, low-cost, and secure platform for building decentralized applications. ZKSync uses the same basic principle as other ZK rollups but has several unique features that distinguish it from other implementations.

Specific Features and Goals of the ZKsync Project

ZKsync applies cryptography which is the key technology protecting people’s freedom today it's the only technology that can enable a single individual to resist immensely powerful adversaries.

They also apply advanced cryptography of zero-knowledge proofs to eventually eliminate all trust assumptions from the realm of public blockchains.

zkSync is and will always remain fully open source under permissive software licenses (such as MIT/Apache 2.0), so anyone can view, audit, modify and fork the code.

zkSync Era is designed to accelerate the widespread adoption of blockchain technology by making decentralized applications more accessible and affordable.

zkSYNC will enable cheap computation and enable new types of dapps that can process significantly more data on-chain than was previously possible.

It Will also offer cheap Storage through zkPorter; and create an unlimited throughput time by introducing the concept of hyperchains; (Hyper chain are sovereign ZK-chains on Ethereum, connected with a network of cheap and fully trustless Hyperbridges).

zkSync Era's security model is the only one that can guarantee 100% of the security of Ethereum. It doesn't rely on fraud proofs or game theory. Instead it's based on fundamental mathematical and cryptographic primitives. zkSync Era publishes cryptographic proofs to Ethereum's Layer 1 (L1), along with the data needed to validate and reconstruct all transactions. This makes it impossible to spoof or corrupt the transactions state, ensuring users' funds are safe.

With the prior aim of onboarding the first billion users to web3 zkSYNC Era supports native account abstraction this will upgrade users from externally owned accounts (EOAs) to smart contract accounts (CAs)

According to Argent

“Unlike other ZK-rollups that are EVM compatible… zkSync supports Account Abstraction. Account abstraction turns every account into a smart contract with its own logic. This is huge because it enables everyone to have an account adapted to their needs, making crypto secure and easy for everyone with seamless compatibility.”

In not too long era will replace private keys and seed phrases prone to getting lost or being hacked with biometric verification and social recovery via family, friends or a selected third party.

Users will be able to sign into Ethereum with their web2 profile and customize permissions for at an individual app level.

zkSYNC Era will introduce Paying fees in any token and Eliminate the friction of funding new wallets with ETH to start transacting.

Overall, zkSYNC Era is expected to be a game-changer in the blockchain ecosystem, maintaining its core values of decentralization and security while making it more efficient and privacy-oriented
