Odaily Planet Daily News Optimism announced on the X platform that its open source, permissionless fault proof has been launched on OP Mainnet, and OP Stack has reached the first stage of decentralization. Soon more OP Stack Chains will be upgraded to include this feature, with the first projects being Base, Metal, Mode and Zora. Fault proof allows ETH and ERC-20 tokens to be withdrawn from OP Mainnet without the need for a trusted third party, enabling users to question and delete invalid withdrawals, and contribute to the security of Superchain. In the coming months, the official will launch more proof systems on the testnet, including Asterisc and Kona. Proving the reliability and robustness of these redundant proof schemes will help Superchain reach the second stage of decentralization, managed only by smart contracts.
