Coinbase-backed Base to improve decentralization with fault proofs

As a seasoned crypto investor with a knack for staying abreast of the latest developments in the blockchain space, I find the upcoming mainnet launch of fault-proof systems by Base intriguing. With my past experiences of navigating the complex world of decentralized finance, I appreciate any initiative that aims to enhance security and remove the need for trusted third parties.


The Ethereum layer-2 blockchain project supported by Coinbase, known as Base, is poised for increased decentralization due to the adoption of a novel, fault-tolerant system.

On October 23, Base revealed plans for the imminent release of their mainnet, featuring robust verification systems for transactions, specifically ensuring the legitimacy of withdrawals.

Starting October 30, users will be able to oversee and contest unjustified withdrawals, thereby eliminating the necessity of a reliable intermediary, as stated by Base. This means that users can now independently verify transactions, reducing dependency on external parties.

Base to launch fault proofs twice as fast as Optimism

In order to guarantee a flawless debut for their robust system, Base is actively working hand-in-hand with Optimism, a well-known Ethereum L2 player who specializes in fault-tolerant technology advancements.

Following the successful testing of fault-proofs in October 2023, Optimism rolled out the implementation of these fault-proofs on the main network in June 2024. This transition required a period of approximately six months for the integration of the system onto the main network.

For Base, it’s planned that their fault-resistant mainnet switch will occur in half the time compared to Optimism’s, given that Base implemented fault-resistance features on their testnet in July 2024.

When error-proof verifications are enabled, users can securely transfer assets from secondary layers such as Base or Optimism back to the main Ethereum network (Layer 1) without requiring assistance from any centralized service. This new feature, though, brings about some modifications in the withdrawal process.

What’s changing to withdrawals on Base?

After implementing Base’s fault-tolerant proofs on the primary network, withdrawals will be about verifying and confirming through the fault-resistant system.

Before the update, any withdrawals will need to undergo a seven-day verification period before they can be completed. Meanwhile, transactions occurring during or after the fault-free system upgrade will be processed without issue. Typically, this process takes seven days, but if there are challenges, delays may occur. (Base)

During an upgrade, any pending withdrawals will require fresh verification or proof again. This was mentioned in the latest update on X.

As a crypto investor, I appreciate the assurance that any necessary contract upgrades will be executed seamlessly and without a hitch. In other words, if my favorite blockchain (L1) requires an update, it’ll all happen in one go – no separate transactions needed for each contract. Plus, I won’t have to lift a finger as node operators – the work will be taken care of automatically.
