PANews reported on October 24 that according to the official announcement of Base, the Base mainnet will introduce fault proofs on October 30, marking an important step towards decentralization. After the introduction of this mechanism, anyone can monitor and challenge invalid withdrawal transactions without permission, eliminating the need for third-party trust. The Base team said that they have been working closely with Optimism to ensure that the fault proofs are successfully launched and upgraded safely. During the upgrade, all pending withdrawal transactions will need to be re-verified.
