Base Blockchain Recovery After Two-Hour Outage
Coinbase's Base blockchain has resumed operations following a two-hour outage that paused block production and transaction processing, according to CoinDesk. An invalid block was identified as the trigger, and the team continues to investigate the root cause while advising node operators to restart their systems.
Coinbase's Ethereum layer-2 network, Base, resumed block production after a two-hour outage that halted transaction processing. The problem began around 16:03 UTC when Base reported that its mainnet block production was "unhealthy." By 16:52 UTC, the team identified an issue related to an invalid block and initiated remediation efforts.
The outage represents another disruption for Base, which had previously experienced downtime in August 2025. The Base team stated that internal node synchronization was restored, but they are still investigating the cause of the invalid block. It is currently unclear if the issue came from a software bug or a consensus-related fault, and updates on network stability are forthcoming.
This incident highlights the operational vulnerabilities faced by layer-2 networks, which are built to enhance scalability and transaction speed on the Ethereum blockchain. Such outages could raise concerns among users and developers about the reliability of these systems, especially as more applications migrate to layer-2 solutions for efficiency.
As Base continues its investigation, stakeholders will be watching closely for any revelations that might explain the technical failures and the measures being implemented to prevent future occurrences. Transparency in this matter is crucial for maintaining trust within the rapidly evolving crypto ecosystem.
