Base Layer 2 mainnet to launch fault proofs on October 30

Base, an Ethereum Layer 2 (L2) scaling solution, will introduce fault proofs to its main net on October 30th, 2024. This upgrade is expected to foster a more decentralized environment. Under the new Layer 2 Base mainnet implementation, any party can monitor and contest an improper withdrawal transaction without centralized entities’ consent for further security.

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

Base’s team enhances withdrawal processes by introducing a new upgrade

The upcoming upgrade will bring some notable changes to how withdrawals are processed. First, it is essential to note that withdrawals will involve proving and finalizing using the fault proof system.

As part of the transition, the contract handling output proposals, previously managed by the ‘L2OutputOracle,’ will be replaced by the ‘DisputeGameFactory.’ This change is designed to enhance the security and integrity of the Base’s state transition process.

Additionally, withdrawals initiated before the upgrade will still undergo a 7-day challenge period before finalization. After the fault proof upgrade, withdrawals will similarly be proven and finalized through the new system, with a standard 7-day finalization window, subject to potential delays if any challenges arise.

Base’s team has been working very closely with Optimism to ensure this fault proof mechanism is well integrated. 

Base mainnet urges bridge operators to prepare for fault proof integration

All teams that are operating bridges on Base mainnet are requested to inform their users and check their systems to make sure that they are compatible with the new L1 contracts and the fault proofing logic. All the necessary contract upgrades will be done atomically; hence, node operators will not be required to do anything more.

The Layer 2 Base mainnet was launched in July 2024. Given its newcomer status, the network has received considerable attention. Base is designed to become a critical Layer 2 player in terms of security, cost-effectiveness, and developer convenience.

The adoption of fault proofs will assist in developing trust in the network, increase community involvement, and realize Base’s long-term vision of a decentralized home for blockchain applications.
