Linea, an Ethereum L2 network, has recently announced that its team has successfully completed the first phase of all code repository open-source activities. This initiative is aimed at ensuring that users can freely view, copy, and modify the code. One of the main goals of this phase was to achieve 100% EVM coverage in the zkEVM algorithm, which enables computation proofs for all EVM operations and precompiled code to unlock the potential for trustless execution. To further guarantee the system's security and reliability, the computation standards have been disclosed and will be subject to community audits and participation in bug bounty programs. This not only enhances user trust in the system but also provides a strong basis for future possible security enhancements.
