Ethereum software firm ConsenSys has released a public testnet of its zero-knowledge Ethereum Virtual Machine (zkEVM), and has given it the name “Linea.”

ConsenSys launched a private testnet for its zkEVM in December. Since then it has processed over 350,000 transactions. In a blog post, the team behind Linea said that “Linea represents the next evolution of ConsenSys zkEVM, powering a new generation of dapps built on Ethereum.”

ConsenSys also tweeted that Linea would natively integrate its widely used MetaMask wallet and Truffle, its developer toolkit.

Zero-knowledge (ZK) technology is seen by many as the ultimate expansion system for blockchains by increasing the speed of transactions and reducing their fees.

A zkEVM is a type of ZK rollup that is compatible with Ethereum Virtual Machine, the software that deploys smart contracts. Having a ZK rollup that is compatible with the EVM means developers won’t need to reconfigure their applications on Ethereum and can move them over without any hiccups.

In recent days there has been a lot of activity in the zero-knowledge space in the Ethereum ecosystem. Matter Labs and Polygon both came out with their own zkEVMs, closing out the race for bringing Ethereum-compatible ZK rollups to users.
