According to BlockBeats, Optimism announced on June 11th that an open-source, permissionless fault proof has been launched on the OP Mainnet, marking the first stage of decentralization for the OP stack. This development allows for the extraction of ETH and ERC-20 tokens from the OP Mainnet without the need for a trusted third party. There are plans to extend the fault proof to other chains based on the OP Stack, including Base, Mode, and Zora.

The second phase of the OP Mainnet aims to achieve complete decentralization and permissionless operation, managed solely through smart contracts. This represents a significant step forward in the blockchain technology, promoting a more secure and efficient system for transactions and contracts.
