Base is gearing up to deploy its 'fault proofs' feature on the mainnet effective October 30, providing users the ability to monitor and dispute any potentially fraudulent withdrawals.
In Brief
Starting October 30, Base will implement its 'fault proofs' mechanism, enabling users to independently track and challenge withdrawals that might be invalid, without the need for a trusted intermediary's consent.

Ethereum Layer 2 blockchain, Base The announcement regarding the implementation of 'fault proofs' on Base's mainnet starting October 30 has been made, which will facilitate independent monitoring and challenge of any invalid withdrawal interactions. Optimism These 'fault proofs' signify a pivotal advancement towards achieving decentralization in Layer 2 solutions, enabling a fairer and more democratic validation process for the state of Layer 2 networks.
In essence, fault proofs enhance decentralization through two fundamental components: open submissions for output proposals and permissionless dispute mechanisms for those proposals. Previously, only a single centralized entity could submit output roots reflecting the Layer 2 status. However, with the introduction of fault proofs, the process becomes more accessible, enhancing community engagement by allowing everyone to voice claims regarding Base's status. If any of these claims are found to be incorrect or deceptive, they can be challenged by any party.
The rollout of fault proofs on Base's mainnet on October 30th represents a significant leap forward in their journey towards a more decentralized network.
As fault proofs come into play, the withdrawal process on Base will adapt to utilize this new verification system. The existing ‘L2OutputOracle’ will be replaced by the ‘DisputeGameFactory’, which will now handle the generation of output root declarations. This shift is a vital aspect of the overall transition to a more security-focused fault-proof framework.
Withdrawals made prior to the upgrade that transfer from Layer 1 to Layer 2 will still be governed by the usual seven-day challenge period before they can be finalized. However, transactions executed during or after the fault proofs upgrade will be validated using this new system. While the usual timeline for transaction finalization sits at about a week, any challenges raised might induce additional delays.
For projects running bridges on Base Mainnet, it is advisable to keep users updated through their interface regarding the activation of fault proofs in late October. Additionally, operators managing bridges should review and potentially update their bridging protocols to align with the new Layer 1 contracts. Base Mainnet Base operates as a Layer 2 solution designed to enhance the scalability of on-chain user interactions. Initially developed within the Coinbase ecosystem, Base is committed to a long-term vision of gradual decentralization. The platform is constructed on the Bedrock framework of the OP Stack, in collaboration with key industry partners.
