In a move to deliver the true promise of decentralization, an Ethereum layer-2 blockchain Base has launched a new fault-proof solution. In a Thursday blog post, Base disclosed that the solution will be launched on mainnet very soon, emphasizing the mechanisms put in place to verify the correctness of a transaction.
With fault proofs coming to the layer-2 chain, users will now be able to seamlessly track and query invalid withdrawals, a development that eliminates the presence of a trusted third-party.
Base partners Optimism for smooth fault proofs mainnet launch
To ensure a hitch-free mainnet launch, Base said it has collaborated with Optimism, making the solution twice as fast as possible. Don’t forget that Optimism, like Base, also runs as an Ethereum L2. The blockchain network has also been involved in fault-proof tech development.
Late last year, Optimism launched its own fault proofs on the testnet before going on mainnet in June 2024. By bringing its technical expertise into the partnership, Optimism will ensure a smooth launch of Base’s flagship fault proofs system.
Meanwhile, the fault-proof solution introduced by Base had been available on testnet since July 2024. Through the aid of this system, users will be able to withdraw their assets from L2 chains such as Base or Optimism to the major L1 Ethereum blockchain without the involvement of any centralized authority. This strategic innovation brings a drastic change to the process of withdrawals within the ecosystem.
According to Base, every withdrawal before the upgrade will experience a seven-day challenge period before finalization. It added that those withdrawal transactions with pending statuses during the upgrade will be re-proven before they can be finalized.
Base also hinted at the possibility of completing the upgrade atomically. This means all affected L1 contracts will be upgraded through a single transaction, with no action required from node operators.
