Cronos Labs has announced the alpha mainnet launch of the Cronos zkEVM, marking the first chain to go live using the ZKsync tech stack alongside the Era chain.



Cronos zkEVM is a result of a collaboration between Cronos Labs, Matter Labs (a contributor to ZKsync), Crypto.com and a collection of dapp partners. The network has been in testnet since December 2023.



The new chain joins the existing Cronos POS and Cronos EVM blockchains, which collectively manage over $6 billion in user assets, according to Cronos Labs.



The POS chain was the first, launched in 2021 as a <a href="https://blockworks.co/tag/cosmos">Cosmos</a> appchain developed in partnership with the Crypto.com exchange. The second was an EVM-compatible chain, which came online in 2022, also using the Cosmos SDK.&nbsp;



In launching the zkEVM, Cronos is expanding its ecosystem into the <a href="https://blockworks.co/tag/zero-knowledge-rollup">zk rollup</a> space of Ethereum layer-2 networks.

Native account abstraction capabilities allow users to pay transaction fees in a variety of tokens, and one of the novel features of the Cronos zkEVM is its use of zkCRO, a liquid-staked version of CRO, as its primary gas token.



Ken Timsit from Cronos Labs expressed the team&#8217;s commitment to advancing blockchain technology and contributing to open-source projects.



“We would like to help to realize the long term vision of Ethereum on a path towards infinite scalability and mainstream adoption,” Timsit said.



Cronos app developers, such as VVS Finance, Fulcrom Finance and Veno Finance, are committed to deploying on the new chain, and Cronos Labs says at least 20 more are on the way.



As part of the Elastic Chain, the new Cronos chain will have access to the same native Ethereum bridge as ZKsync Era.



ZKsync’s June <a href="https://blockworks.co/newsletter/research/issue/post_c70ea28f-4c2e-477e-8e01-488f1b17808a">protocol upgrade</a> made it possible for the Cronos zkEVM to join the Elastic Chain according to Anthony Rose, Matter Labs’ chief technology officer.



“‘Shared bridge’ is actually a bit of a clumsy name. This isn’t just a bridge, this is a series of smart contracts on Ethereum that supports all of the chains that will be deployed into the network,” Rose told Blockworks.



Because the assets are stored together “you can do protocol level transfers between ZK chains, without needing [a layer-1 transaction] to update balances, etc.” he said.

In an effort to bootstrap usage, Cronos is promoting zkCRO as a “triple yield” opportunity, factoring in native staking yield, plus any yields from DeFi dapps, as well as ZK token incentives allocated to the project following the <a href="https://blockworks.co/news/zksync-to-distribute-21-billion-zk-tokens">ZKsync airdrop</a>.



Cronos piggybacks on the Maker DAI Savings Rate, to offer a yield-bearing vUSD stablecoin, minted from assets bridged to the Cronos zkEVM. Unlike sDAI, which increases in value over time, vUSD will be pegged to DAI 1:1 with the yield portion claimable from the Veno Finance dapp, <a href="https://docs-zkevm.cronos.org/getting-started/about-zkcro-veth-vusd/vusd">according</a> to its documentation.

The alpha phase of Cronos zkEVM is expected to last until September 2024. Rose analogizes the new chain to the second of two computers connected on a single network.



“As more ZK chains are deployed, they’ll be joining these, which is the horizontal scalability we’ve talked about,” he said.

Cronos zkEVM on ZKsync Elastic Chain reaches mainnet

The network of Ethereum layer-2 rollups using zkSync’s ZK Stack got a new addition Thursday, with the launch of the Cronos zkEVM testnet.



Blockchain developer Cronos Labs is developing its third blockchain, which is the first to use ZK Stack hyperchain to reach a live testnet.



The first chain in the Cronos ecosystem was a Cosmos appchain developed in partnership with the Crypto.com exchange and launched in 2021. Cronos then followed up with an EVM-compatible chain, also built using the Cosmos SDK in 2022. This new effort augments, but does not replace, the prior two chains.



Cronos’ zkEVM is the result of a collaborative effort involving Cronos Labs, <a href="https://blockworks.co/tag/matter-labs">Matter Labs</a> (the team behind zkSync), and several engineering teams from stakeholders <a href="https://blockworks.co/tag/cryptocom">Crypto.com</a> and dapp developers on the existing chains.



The zkEVM testnet is built on top of the Ethereum Sepolia testnet and leverages <a href="https://blockworks.co/news/zk-rollups-vie-throughput-crown">zkSync’s new open-source prover, Boojum</a>, a STARK-based zero-knowledge proof system, notable for its low hardware requirements and low fees in the layer-2 rollup space.

Launching a native Ethereum chain was motivated by frustrations with bridging across EVM chains and between Cosmos and Ethereum, according to Ken Timsit, managing director at Cronos.



“When we started building Cronos as an EVM chain, we were, of course, already convinced that the <a href="https://blockworks.co/tag/ethereum">Ethereum</a> developer ecosystem has richness and robustness that has no comparison when it comes to building DeFi and NFT applications,” Timsit told Blockworks.



Good relations with Matter Labs and a desire to contribute to the open source development of the ZK Stack led them to take the next step.



Hyperchains share components of the ZK Stack, including a shared native bridge to the Ethereum mainnet and zkSync’s trustless bridging mechanism, in which assets remain secured by Ethereum.&nbsp;



It will also benefit from zkSync&#8217;s native account abstraction, which allows transactions fee payment in various cryptocurrencies, such as Cronos’ token (<a href="https://blockworks.co/price/cro">CRO</a>).



“When you look at legacy chains, it&#8217;s very hard to migrate Ethereum assets, for example, to account abstraction enabled wallets,” Timsit said. “And so for us, starting by default with account abstraction is a way to take advantage of what this technology offers, better than what we can do on a chain which already has an ecosystem of wallets and tokens.”



Cronos’ zkEVM is expected to progress to mainnet in the second quarter of 2024.



<h2 class="wp-block-heading">Growing hyperchains</h2>



A handful of other hyperchains are in development using the ZK Stack, notably GRVT, (pronounced “gravity”) a derivatives exchange, and Tradable, which is working on bringing private credit on-chain.



Tradable intends to have an institutional focused hyperchain, eventually forming a decentralized chain alongside other institutional partners, according to Omar Azhar, Matter Labs head of business development.



“I think what you might start seeing is app specific chains and then ecosystem specific chains,” Azhar told Blockworks.



Matter Labs sees the zkSync hyperchain as strictly a better option than app-specific chains in Cosmos, such as Cronos’ earlier efforts, said Marco Cora, senior vice president of business and operations. That’s because Cosmos chains generally must provide for their own validator set and security, and lack native token bridges to Ethereum.



“If you are an appchain developer, why are you taking on these two extra projects that you shouldn&#8217;t really focus on: building the bridge and bootstrapping the security?” Cora told Blockworks.



The ZK Stack competes with other well-funded networks building zkEVM chains, including <a href="https://blockworks.co/tag/polygon">Polygon</a>, whose Chain Development Kit (CDK) shares many of the same goals, and <a href="https://blockworks.co/tag/starkware">StarkWare’s</a> Starknet, the progenitor of <a href="https://app.blockworksresearch.com/glossary#zero-knowledge-scalable-transparent-argument-of-knowledge-zk-stark">STARK</a> prover technology which both Polygon and zkSync have iterated upon.



Hyperchains can also serve the purpose of private blockchain frameworks such as Hyperledger or Corda, Cora said, but with all the benefits of Ethereum.



“They are technically highly scalable, but they practically don&#8217;t scale. When you speak with most enterprises, they tell you this is way too expensive for what it is for me,” he said.



Aside from cost considerations, there’s the social coordination problem.



“If you&#8217;re Goldman Sachs, you don&#8217;t want to join the Morgan Stanley Chain just because it&#8217;s the Morgan Stanley Chain. If you&#8217;re Fidelity, you don&#8217;t want to join the BlackRock Chain just because it&#8217;s the BlackRock Chain and so on and so forth,” Cora said.



“But if the sponsor of the chain…forced himself to create a zero knowledge proof and to hand this proof to a third party — which is Ethereum — they now can claim a much higher degree of credible neutrality,” he added. “Now, this party cannot mess with the system.”

 </ul>
 
</div>



A&nbsp;public blockchain network supported by Crypto.com said Tuesday it has launched a $100 million accelerator program to support developers undertaking new blockchain projects.



<a href="https://cronos.org/" target="_blank" rel="noreferrer noopener">Cronos</a>, the Ethereum Virtual Machine-compatible network, announced the program is aimed at assisting projects in the advanced DeFi, Web3 gaming and infrastructure space that are looking for funding and mentorship.



Those accepted to the 10-week cohort-based program will be assigned to mentors from within the ecosystem. Between 3 to 4 cohorts will be selected each year, with an average of ten startups in each. Members will have the opportunity to attend weekly workshops that touch on topics linked to protocol-building. 



The Cronos Accelerator has a tie-up with key partners for investment, mentorship and workshops, including Mechanism Capital, Spartan Labs, IOSG Ventures, OK Blockchain Capital and AP Capital.



“Through Cronos Accelerator, we want to enhance the potential of projects that sincerely want to help grow the ecosystem by providing support in almost every area of their operations,” Ken Timsit, Cronos managing director, said in a statement.



Chosen projects will also have the chance to nab seed investments worth between $100,000 to $300,000 from Cronos Labs and other established venture capitalists. They will be given marketing support and access to Cronos’ user base via introductions through social media and AMA webinars.



Timsit told Blockworks the current market downturn is a good time for founders to think harder about user problems, while early adopter token rewards are less effective.



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">&#8220;A soft market environment can be an attractive time to start a startup accelerator, because the value proposition of an accelerator is all about iterating and fine-tuning a product idea in order to reach product market fit,&#8221; he said.</blockquote>



The announcement comes less than two weeks after Crypto.com named former Bittrex executive Kwon Park as its <a href="https://cms.blockworks.co/crypto-com-hires-to-further-web3-ambitions/" target="_blank" rel="noreferrer noopener">new managing director</a> to help drive its Web3 ambitions.



Despite a recent market downturn, it appears some crypto companies are seeking to shore up business opportunities through sizeable investments.



Rarible recently <a href="https://cms.blockworks.co/web3-watch-netflixs-nft-scavenger-hunt-and-elvis-metaverse-strategy/" target="_blank" rel="noreferrer noopener">launched</a> its own accelerator and grant program dubbed <a href="https://join.accelerari.xyz/" target="_blank" rel="noreferrer noopener">AcceleRari</a>. Using a pitching process, five non-fungible token (NFT) projects will earn support and resources from Rarible’s protocol team. The Sandbox’s parent company, Animoca Brands, announced a similar $30 million <a href="https://cms.blockworks.co/animoca-brands-and-brinc-to-invest-up-to-30m-in-play-to-earn-ecosystem/" target="_blank" rel="noreferrer noopener">Guild Accelerator Program</a> in February.
