zkEVM
A zero-knowledge rollup that is Ethereum Virtual Machine compatible — able to execute and prove Ethereum smart contracts using zero-knowledge proofs. zkEVMs combine the EVM's smart contract compatibility with zkRollup security and efficiency. Building a zkEVM is technically more complex than an optimistic rollup, but eliminates the 7-day challenge period, enabling faster withdrawals to Ethereum mainnet. Polygon zkEVM, zkSync Era, Scroll, and Linea are the leading zkEVM implementations.
