Cronos Labs has launched the public testnet of its upcoming Cronos zkEVM Chain, which is built using zkSync’s zero-knowledge (zk) technology stack.
The new layer 2 network is a zk-rollup hyperchain currently deployed as a testnet on top of Ethereum’s Sepolia testnet. It is the first live hyperchain built on zkSync zk-stack, according to the announcement blogpost.
The novel L2 from Cronos is built using the latest Boojum STARK-based zero-knowledge proof system, which runs on minimum hardware requirements and hosts the rollup with the lowest fees possible.
It was developed with the combined efforts of Cronos Labs, VSS Finance, Fulcrum, and Veno Finance.
“We’re extremely excited to see Cronos deploying a hyperchain,’ said Marco Cora, senior vice president of business and operations at Matter Labs.
“With their extensive and diverse ecosystem of millions of users as well as the impressive financial value stored on-chain, they will be a great use case for the mass adoption of hyperchains.”
Hyperchains are zkEVM-based chains running in parallel and with a common settlement on the Ethereum network.
With the launch, Cronos Labs said that the team will look further to prepare for the mainnet launch while continuing to experiment with layer 2 technology to strengthen the Cronos ecosystem.
