Ethereum Layer 2 network Base is set to implement Optimism’s fault-proof system, also known as fraud proofs, on October 30.
According to the project’s team in a recent post on X, the upgrade will allow users to independently verify withdrawals without the need for third-party involvement, enhancing transparency and trust in the network.
Fault proofs are coming to Base mainnet on October 30th, marking a key milestone on the path to decentralization
This means anyone can monitor and permissionlessly challenge invalid withdrawals, removing the need for a trusted third party

The Base team described the rollout of Optimism’s fault-proof system as a significant step in its decentralization efforts. Currently, only centralized entities can submit network state updates, but with this shift, the platform seems to want to increase community oversight and participation.
The collaboration with Optimism introduces permissionless output proposals, allowing community members to assert claims about the network’s state without depending on a central authority. Additionally, users will be able to contest fraudulent or erroneous claims through a decentralized mechanism, promoting greater community involvement in securing the network, as outlined in Base’s technical documentation.
The Base team also emphasized that any pending withdrawals on the platform the at the time the upgrade occurs will need to be re-proven
The Optimism team developed fault proofs to prevent inaccurate transaction data from being transmitted to Ethereum’s Layer 1 blockchain. The network started testing in March 2024. The feature was officially added to the OP Stack and activated on OP Mainnet in June 2024. The Optimism team claimed that they lay the foundation for a multiple-proof system that makes the network “more resilient to potential attacks and bugs in any one proof system.”
Meanwhile, this update follows other developments at Base, including the recent appointment of Jesse Pollak—the network project’s lead—to join Coinbase’s executive team to oversee Coinbase Wallet alongside his current role.
Pollak noted that this alignment helps make blockchain technology more accessible and connects users to a wide range of decentralized products. He reassured the community that Base will continue prioritizing decentralization and inclusivity, stating that the network will remain “a bridge rather than an island” and stay committed to open-source principles.
