TechFlow news — Polygon has announced the launch of the Polygon zkEVM public testnet, the first zkEVM to enter a public testnet phase using an open-source ZK proving system. This new technology will deploy the Ethereum Virtual Machine (EVM) for its ZK rollup, meaning developers won't need to learn a new programming language and can seamlessly migrate their smart contracts from Ethereum. AAVE, Uniswap, and the Web3 social platform Lens are among the first protocols to adopt this zkEVM testnet.
However, Polygon noted that the current testnet version does not yet meet its ultimate goals. It currently falls under Vitalik Buterin's framework as a "Type 3" protocol—nearly equivalent to the EVM, but with some compromises on exact equivalence in order to reduce prover time and improve developer experience. Polygon zkEVM aims to evolve into a "Type 2" solution, meaning it will eventually be internally "fully indistinguishable from Ethereum." The testnet will help accelerate progress toward full Type 2 compatibility. Additionally, the current testnet version has limited throughput capacity, indicating it is far from being the optimized scaling solution in its final form, and significant development remains ahead.Original link
