The OP Stack fault proof system has been launched on the OP Sepolia test network

Golden Finance reports that the OP Stack fault proof system has been launched on the OP Sepolia test network, marking an important milestone in the second phase of decentralization for the OP Stack chain. The fault proof system can perform permissionless verification and challenge and reject invalid ETH and ERC-20 token withdrawals. Currently, contributors to Optimism are focusing on developing various proof schemes and preparing a fault-tolerant system for mainnet deployment.
