Base, an Ethereum Layer 2 (L2) scaling solution, will launch fault proofs on its mainnet on October 30, 2024.
This upgrade is expected to improve network security and decentralization by allowing any party to challenge improper withdrawal transactions without relying on centralized entities. The new fault-proof system is critical in ensuring transparency and trust within the Base ecosystem.
Enhanced withdrawal process with fault proofs
As part of the upcoming changes, the base is introducing a new approach to verifying and finalizing withdrawals. The fault-proof mechanism will ensure that each transaction undergoes a verification process before completion. This added layer of security aims to safeguard users and the network against fraudulent or incorrect withdrawals.
In this new system, the existing contract that handles output proposals, the ‘L2OutputOracle,’ will be replaced by the ‘DisputeGameFactory.’ This change is designed to enhance the integrity of the state transition process. Withdrawals initiated before the upgrade will still follow the existing 7-day challenge period, while withdrawals after the upgrade will also go through the fault-proof system, maintaining the same 7-day window. If a challenge is raised, the withdrawal may be delayed until the dispute is resolved.
Cooperation with optimism for fault-proof integration
The base has collaborated closely with Optimism to ensure the seamless integration of the fault-proof mechanism into its system. This cooperation highlights the shared goals of both Layer 2 projects in improving security and decentralization within the Ethereum ecosystem. The Base development team has confirmed that the contract upgrades will occur atomically, meaning node operators will not need to take additional steps during this transition.
Bridge operators are advised to prepare
Bridge operators on the Base mainnet are urged to prepare for the upcoming changes. They are advised to review their systems and ensure compatibility with the new fault-proof logic and updated Layer 1 contracts. The Base team has recommended that operators notify their users and check for required adjustments to maintain smooth operations post-upgrade.
Launched in July 2024, Base is positioning itself as a critical player in the Layer 2 space, focusing on security, cost-efficiency, and user-friendly development tools. Adopting fault proofs is expected to increase confidence in the network, promote greater community participation, and help Base realize its vision of creating a decentralized environment for blockchain applications. By adding fault proofs, Base aims to enhance security and transparency while encouraging a more active and involved community.
