OP Stack failure proof system is online on OP Sepolia testnet

The OP Stack Fault Proofing System has been launched on the OP Sepolia test network, marking an important milestone in the decentralization of the OP Stack chain in its second phase. The Fault Proofing System allows for unauthorized verification and can challenge and reject invalid ETH and ERC-20 token withdrawals. Currently, contributors to Optimism are focused on developing various proofing solutions and preparing error prevention systems for deployment on the main network.
