Coinbase’s Base investigates suspected invalid block after two-hour outage

Coinbase’s layer-2 network Base suffered an outage of about two hours on Thursday after an invalid block triggered a consensus failure that halted all transactions on the chain. The disruption began at 16:03 UTC, when Base’s status page flagged mainnet block production as “unhealthy.” Base later said operations were restored, user funds remained secure, and a full post-mortem would follow.
