ChainCatcher news, according to The Block, OP Labs has released fault proofs on the OP Mainnet, advancing decentralization to the first phase, which allows the withdrawal of ETH and ERC-20 tokens from the OP Mainnet without a trusted third party, enabling users to challenge and remove invalid withdrawals. The plan is to extend fault proofs to other chains based on the OP Stack, including Base, Metal, Mode, and Zora.It is reported that the second phase of the OP Mainnet aims to achieve complete permissionless and decentralized management solely through smart contracts.
