Coinbase-backed Ethereum layer-2 network Base resumed block production on Thursday after a roughly two-hour disruption that halted the blockchain.
In an update, the Base team said the chain is working again and the internal nodes were syncing correctly, although it continues to investigate the cause of the incident. The team also advised ecosystem node operators to restart their base nodes to restore synchronization.
The first public indication of problems came at 16:03 UTC, when Base reported that mainnet block production was “unhealthy”. At 16:52 UTC, the team said it had identified an issue and was undertaking multiple remediation efforts.
The incident temporarily halted transaction processing on one of Ethereum’s largest Layer-2 networks. Base has not yet disclosed what caused the invalid lock and whether the problem stemmed from a software glitch or another consensus-related error.
The network also had an outage in August 2025.
The team said it will continue to monitor network stability and provide further updates as the investigation continues.
