zkSync Era launches with Uniswap and Sushi — First zkEVM on mainnet

A new Era has dawned with the launch of the first Ethereum Virtual Machine compatible ZK rollup, enabling projects like Uniswap and Sushi to easily port over for scaling.

Some of the biggest names in decentralized finance, including Uniswap, Sushi, Maker and Curve, are set to launch March 24 on zero-knowledge proof roll-up zkSync Era.

The Ethereum layer 2 scaling network has finally opened to users in alpha after four years in development, enabling faster and cheaper transactions. It is the first Ethereum Virtual Machine compatible zk-Rollup to launch on mainnet (competitor StarkWare uses a bespoke language called Cairo), allowing most Ethereum DApps to simply port over with very few changes.

Between 32 to 50 projects are expected to go live on March 24 or over the weekend, including Balancer, Pyth Network, Mute, Redstone, Graph and Argent. Banxa, Yearn Finance, Celer, Chainlink, Aragon, Woo Network and Tracer DAO are also porting to the network.

“Friday for us is the big one, it’s full launch alpha,” Anthony Rose, the head of engineering for zkSync developer Matter Labs, told Cointelegraph earlier in the week.

“But the systems are super complex and there's a million other things we want to do.”

While zkSync Era can provide scaling "orders of magnitude" greater than Ethereum’s current 10 to 12 transactions per second (TPS), Rose said it would offer “tens of TPS” initially and scale up as demand requires.

The project launched its “fair onboarding alpha” on Feb. 17, allowing projects to port over and test out security and optimizations. Matter Labs said it spent $3.8 million on security testing, seven independent security audits and a bug bounty program to reduce the risk of any incidents.

What is a zk-Rollup?

Zk-Rollups — which include zkSync, Scroll and solutions from Polygon, StarkWare and Consensys — compute transactions away from the Ethereum blockchain while providing a tiny cryptographic proof that is written as a single transaction back on Ethereum showing that a bundle of other transactions has been carried out correctly. zkSync also employs recursion, which generates a proof showing a batch of other proofs (each representing many transactions) have been carried out.

Zk-Rollups can enable virtually instant withdrawals, giving them an advantage over optimistic-rollup layer 2s such as Optimism, where withdrawals take a week. However, zkSync Era will impose a 24-hour waiting period initially as a security precaution.

“The reason being is if you have some critical bug that has somehow got through the many different audits and security mechanisms and somebody completely drains the protocol, this is obviously a disaster for everybody involved,” he said. The waiting period is likely to be reduced to an hour within weeks.

Native account abstraction

zkSync has also enabled native account abstraction, meaning every account in the network is a “smart account” that can utilize two-factor authentication (2FA), social recovery, autopay transactions and more via smart contract wallet providers like Argent.

"This was and probably still is my favorite feature,” Rose said, explaining that it’s an improvement on Ethereum’s ERC-4337 implementation and will help remove the “jankiness” for new crypto users getting into the space.

"Scalability is fine, the infrastructure needs to be there. But it needs to come with a user experience that can also scale."

Not decentralized yet

zkSync Era will not be fully decentralized on launch, so the team can implement fast fixes for any security or technical issues. However, a time lock will later be implemented so that the Security Council and community can sign off on decisions.

Like competitor StarkWare, zkSync relies on a centralized sequencer and prover, which are faster, but provide a centralized point of failure. Running a prover, however, requires the purchase of expensive hardware or renting cloud capacity at $10,000 a month, which makes decentralizing that aspect of the network tricker. Underscoring the challenge, the decentralized version of StarkWare is called StarkNet and is currently running at a paltry 0.11 TPS.

Rose said a new proof system was already being developed that substantially reduces hardware requirements and should be available on mainnet this year.

“So the idea for us is to get through this, then start talking about how we upgrade the proof system to be such that we can be meaningfully decentralized,” he said.

“There's lots of hard problems to solve to make the systems real.”

ConsenSys zkEVM set for public testnet to deliver secure settlements on Ethereum

ConsenSys will release its zkEVM rollup to its public testnet on March 28, paving the way for an eventual mainnet integration later in 2023.

ConsenSys has announced the upcoming release of its zero-knowledge Ethereum Virtual Machine (zkEVM) rollup to a public testnet on March 28, allowing for stress testing of the layer-2 scaling technology.

ConsenSys’ research and development team has been working on its zkEVM rollup over the past four years. The zkEVM is touted to offer fast finality, high throughput and security of settlements on the Ethereum blockchain.

A private beta launched in Q4 of 2022 gave early access to limited users, which processed over 350,000 transactions and onboarded various decentralized applications (DApps). The testnet allowed Solidity developers to build, test and launch DApps while testing the zkEVM at scale.

ConsenSys zkEVM is the culmination of work from teams at Infura, Truffle and MetaMask, as well as developers on Besu and Gnark. Integrations and features of the rollup were aimed to remove developer complexity, improve security and expedite onboarding times.

An announcement shared with Cointelegraph highlighted zero switching costs as a benefit to projects in the ecosystem. Developers can build on the zkEVM or migrate existing DApps without changing code or rewriting smart contracts. The zkEVM also uses Ether (ETH) for gas fees, cutting out the need for third-party code translation and other middleware solutions.

ConsenSys zkEVM integrates with MetaMask, which is aimed to expedite the onboarding of users. Infura integration also allows developers to ship DApps at scale. Developers will also be able to build, test, debug and deploy Solidity smart contracts with a variety of layer 2 developer environments powered by Truffle.

ConsenSys also aims to keep its zkEVM open-source after launch. Nicolas Liochon, head of research and development at ConsenSys, told Cointelegraph that the goal of the public beta testnet is to trial the system under the same conditions it would face on mainnet where the stakes are higher.

“Users and developers will be able to permissionlessly interact with our technology stack allowing us to stress test the system under challenging and adversarial conditions.”

Following integration with the public testnet, ConsenSys will carry out a system outgrade. This is aimed at laying the foundation for a “highly performant, trustless, and decentralized network,” according to Liochon.

The final upgrade will also start its auditing and security process to ensure the zkEVM is safe and secure before a mainnet launch earmarked to take place later in 2023.

ConsenSys is in discussions with leading players in the Ethereum ecosystem to deploy and integrate with its zkEVM testnet. Liochon highlighted the focus on making the scaling rollup EVM-equivalent a key factor in making it easy for DApps and tools to switch to its zkEVM.

Liochon also said efforts to make decentralized and trustless applications available to the public require simpler and cheaper systems. The zkEVM aims to achieve this by building a trustless, censorship-resistance, decentralized and performant execution layer that scales Ethereum.

Collaboration with the wider layer 2 ecosystems is also a focus for ConsenSys. Liochon said the organization is looking to work with innovators in the space to convene the first zkEVM “multi-prover” rollup.

This type of scaling rollup would have multiple prover implementations generating validity proofs of computation.

Polygon sets late March launch date for its zkEVM mainnet beta

The Ethereum scaling solutions provider is preparing to launch its long-awaited Ethereum Virtual Machine roll-up technology.

The long-awaited scaling upgrade from Ethereum layer-2 solution provider Polygon (MATIC) has been announced, with the beta launch of its zero-knowledge Ethereum Virtual Machine (zkEVM) mainnet slated for March 27.

In a Feb. 14 blog post, Polygon said that after three and a half months of “battle testing,” the system will be ready for the mainnet launch next month.

It's been touted as “seamless scaling for Ethereum,” and was launched as a testnet in December last year.

The development of the zk-rollup scaling technology has been ongoing for the past three years. During that time, the Polygon zkEVM system has hit several milestones noted by the team.

These include the deployment of more than 5,000 smart contracts, the generation of over 75,000 zk-proofs, more than 84,000 wallets and two public third-party audits.

The team noted that security is the highest priority and that’s the reason “why Polygon zkEVM has been run through a gauntlet of tests and audits.”

The technology uses zero-knowledge proofs — cryptographic confirmations that, in the context of scaling, enable platforms to validate mass amounts of transaction data before bundling and confirming them on Ethereum.

Polygon is not the only team working on a zkEVM solution. Scaling provider zkSync is developing similar EVM technology with its zkPorter — which puts essential transaction data off-chain.

Scroll, another scaling solutions provider, is also building a zkEVM solution in collaboration with the Privacy and Scaling Explorations group, part of the Ethereum Foundation.

The Ethereum Foundation is also funding a project called Applied ZKP, which aims to develop an EVM-compatible zk-rollup.

The team explained the significance of the technology, stating that true EVM-equivalence means Ethereum can be scaled “without resorting to half-measures.”

“The best way to scale Ethereum is to preserve the existing Ethereum ecosystem: code, tooling, and infrastructure needs to just work. And that’s what Polygon zkEVM is aiming to achieve.”

The scaling tech also enables significant transaction cost savings. Proof costs for a large batch of hundreds of transactions are down to about $0.06 and less than $0.001 for a simple transfer, the team added.

Matter Labs, the firm behind Polygon, raised $50 million in a Series B round led by Andreessen Horowitz to build EVM-compatible zk-Rollups in November 2021.

Polygon’s native token, MATIC, has reacted positively to the announcement with a 5.3% gain over the past 12 hours or so. As a result, the token was trading for $1.24 at the time of writing, according to Cointelegraph data.

Chainlink oracle, data feeds coming to StarkNet ecosystem

StarkWare is set to partner with Chainlink Labs to integrate oracle services and data feeds to the StarkNet testnet.

Blockchain scaling technology firm StarkWare is set to partner with Chainlink Labs to bring oracle services, data and price feeds to the StarkNet ecosystem.

The coalition will see StarkWare join Chainlink’s Scale program and brings Chainlink price feeds to StarkNet’s testnet. StarkNet tokens will also fund certain operating costs for Chainlink oracle nodes, giving Starket developers access to Chainlink oracle services and data feeds.

Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data sources, APIs and payment systems. It allows smart contracts to interact with real-world data and events, making it possible for them to be triggered by data from external sources.

The network features independent nodes that provide secure and reliable data to smart contracts, incentivized by payment in Chainlink’s native LINK token. Node operators verify and perform data computations, which ensures accurate and reliable data is delivered to smart contracts.

An announcement from StarWare highlights the establishment of a sustainable economic system between StarkNet and Chainlink. The integration is also expected to provide the necessary infrastructure for StarkNet developers to build “highly performant, increasingly complex, and secure smart contract applications.“

StarkWare product manager and researcher Ohad Barta told Cointelegraph that work to introduce Chainlink’s oracle services to StarkNet has been ongoing since June 2022. Various oracle services will be integrated into StarkNet, according to Barta, highlighting the benefit of diversity in smaller and larger oracles serving the network:

“Oracles are an essential component, they are relevant in many use cases. A lot of applications need to know the price of assets or NFTs. Oracles are like a complete toolkit.”

Barta also believes that the reputation of Chainlink’s services within the Ethereum ecosystem is another major reason for the integration with StarkNet:

“The main benefit is any application or startup can integrate with Chainlink price feeds and know it will be accurate and have some peace of mind when they are building their product.”

A statement from Chainlink co-founder Sergey Nazarov highlighted the partnership’s potential in Chainlink oracle networks operating at high speeds and low costs for Starknet users and developers:

“By reducing the operating costs of oracle nodes, StarkNet is able to accelerate its ecosystem’s growth and become a more attractive environment for building scalable DApps in the Web3 ecosystem.”

Chainlink data feeds are live on StarkNet’s testnet, with a mainnet integration expected in the coming months. Cointelegraph is currently covering StarkWare Sessions in Tel Aviv, Israel, where the company announced that it would make its proprietary Starknet Prover open source. The prover is the engine that StarkWare uses in its zero-knowledge roll-up technology.

Soaring growth of Ethereum layer-2 networks set to continue in 2023

Leading layer-2 networks on Ethereum have seen a surge in daily active users and fees recently.

Ethereum layer-2 networks have gone through an explosive growth phase over the past couple of months a trend that is set to continue in 2023.

According to recent data, the leading layer-2 networks have seen an increase in daily active users which has translated into a growth in fees for the respective ecosystems.

According to analytics provider Token Terminal, Polygon leads the pack with 313,457 daily active users as of Jan. 17. Additionally, the metric spiked to over 600,000 daily active users earlier in January.

It marks a 30% increase in activity since the beginning of October 2022 which has resulted in nearly $55,000 worth of daily fees for Polygon.

Optimism has seen even faster growth with a 190% gain in daily active users over the past three months. This resulted in daily network fees of $119,475, a gain of almost 140% since the beginning of the year.

Arbitrum One currently has 41,694 daily active users, an increase of around 40% over the past three months. Daily fees on the network are just over $40,000 according to the data.

Meanwhile, data from L2 ecosystem analytics platform L2beat states that Arbitrum has a market share of 52% in terms of total value locked (TVL) which is currently $2.55 billion. It has seen a 9% increase in TVL over the past week.

Optimism, the second largest L2 network, has a TVL of $1.46 billion giving it a market share of 30%. Its collateral locked has surged by 15% over the past seven days.

The two together account for more than 80% of all the collateral locked in layer-2 platforms.

There has been an increase of almost 10% in TVL for all L2s over the past week, pushing it up to $4.89 billion. However, the total figure is still down 34% since its peak level in April 2022.

Nevertheless, this decline is less than half of the retreat DeFi TVL has made since its all-time high. DeFi collateral has declined by 75% since December 2021, according to DeFiLlama, suggesting that there is greater demand and momentum for layer-2 networks at the moment.
