The Ethereum layer-2 network Base, supported by Coinbase, has resumed its functions following a disruption that lasted approximately two hours, which affected block creation and transaction processing. The development team indicated that an invalid block was the cause of the problem and is still working to identify the underlying issue, advising node operators to restart their systems to ensure proper functionality.

This incident represents yet another interruption for Base, which had previously experienced a downtime in August 2025. On Thursday, the network successfully resumed block production after the two-hour halt. According to an update from the Base team, the blockchain is operational again, and internal nodes are syncing as expected, although investigations into the root cause of the issue are ongoing. The team also urged ecosystem node operators to restart their Base nodes for synchronization.

The first sign of trouble was reported at 16:03 UTC, when Base flagged that the mainnet’s block production was ‘unhealthy.’ By 16:52 UTC, the team had pinpointed an issue and was implementing multiple corrective measures.

This disruption temporarily interrupted transaction processing on one of Ethereum’s leading layer-2 networks. Base has not yet revealed the reason behind the invalid block or whether it was due to a software error or another consensus-related issue.
