Optimism announced on X Platform that its open source, permissionless proof of failure 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.
Proof of failure allows ETH and ERC-20 tokens to be withdrawn from OP Mainnet without the need for a trusted third party, enabling users to challenge and delete invalid withdrawals, contributing to the security of the Superchain.
In the coming months, more proof systems will be launched 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.
