Ethereum scaling solution Polygon has launched a public testnet of its zero-knowledge Ethereum Digital Machine (zkEVM).

In an announcement on Monday, the Polygon crew said its zkEVM was the foremost to reach public testnet with an open-source ZK proving design.

Rollups are a Layer 2 scaling design that bundles several transactions into a single one by shifting the computation off-chain. In doing so, they decrease congestion on the underlying blockchain, thereby enabling transactions to be processed extra rapidly for a fraction of the worth. Zero-knowledge rollups evaluate that these bundled transactions are exact off-chain.

ZK rollups for an EVM-identical atmosphere will indicate that builders can port their tidy contracts to Ethereum with out having to use any contemporary programming languages. The Polygon crew describes its zkEVM as “the next chapter for Ethereum” as it continues to make scalable choices for the blockchain.

“EVM-equivalence is a spectrum, and the testnet version of Polygon zkEVM is now not but all the pieces we desire it to became,” said Polygon in a blog. In its fresh suppose, Polygon’s zkEVM falls within the “Variety 3” category of protocols by manner of EVM-equivalence, as per a framework outlined by Ethereum’s Vitalik Buterin.

“Our goal is to became a Variety 2, that manner Polygon zkEVM will sooner or later ‘uncover precisely admire Ethereum “from inner,”’” said Polygon.

The Layer 2 scaling solution invited builders to launch “battle sorting out” its zkEVM testnet. Polygon claims that some large names within the DeFi dwelling, including Aave and Uniswap, will soon deploy on the testnet.
