Polygon zkEVM, formerly Polygon Hermez, is a complete EVM-equivalent L2 zk-rollup Ethereum scalability solution..
Hermez zk-rollup is a layer 2 construction on top of Ethereum that solves its scalability through mass transfer processing rolled into a single transaction. The "zero-knowledge proof" (ZK) technology is used to present and publicly record the validity and correctness of the rolled transfers processed on the Ethereum blockchain. By storing just the proof and the compressed data of a batch of transfers, the efficiency and the throughput of the network is multiplied.
