Coinbaseâs Ethereum layer-2 blockchain Base stopped producing blocks for 33 minutes on Tuesday after switching to a backup sequencer that wasnât set up properly to process transactions.
The incident began at 6:07 am UTC when the active sequencer started falling behind on block production, prompting Conductor â Baseâs system for managing sequencer availability and reliability â to switch sequencers.
However, it switched to an âunhealthy mainnet sequencerâ that was still being set up and thus wasnât able to produce blocks, Base Buildâs X account said in a post on Tuesday.
Base creator Jesse Pollak said the core team responded to the issue immediately, with the network fully recovered by 6:40 am UTC. A little more time was taken to ensure a chain reorganization wasnât required, Base said in its post-mortem.
Base is still highly centralized
The incident exposes Baseâs reliance on centralized sequencers to handle transactions at scale. While multiple sequencers run, they rely entirely on Conductorâs management capabilities â creating a single point of failure that can halt the entire network.
The team behind Base, which currently secures more than $4.1 billion of total value locked, said it would update its infrastructure to ensure all sequencers in the cluster can handle block-building responsibilities if selected.
Baseâs only other major network outage occurred on Sept. 5, 2023 â shortly after its public launch â where block production was halted for 43 minutes.
Accountability taken by Base leader
Baseâs head of engineering, who goes by âaflockâ on X, said that Base takes chain uptime very seriously while adding that it canât âpower a global economy without a solid backbone of a network.â
âProud of the team for the quick response here and glad we’ve found several ways to harden our systems going forward.â
Baseâs network outage bullish, apparently
Some crypto pundits viewed Baseâs outage as bullish, including former Coinbase engineer and Save Finance founder, 0xrooter, who said: âpeople only make a fuss about downtime for chains with actual users.â
âBullish downtime,â the pseudonymous developer added.
Helius Labs CEO Mert Mumtaz compared the incident to Solana, another high-speed blockchain that has had its fair share of network outages over the years.

Despite the security challenges, Solana and Base remain among the most used blockchains for retail users, boasting the first and fourth most active addresses at 2.83 million and 1.09 million, respectively, DefiLlama data shows.
Solana is the second-largest chain by DeFi TVL at $9.6 billion, while Base sits at sixth.
