Overview
- The Coinbase‑backed Layer‑2 network stopped producing blocks Thursday for roughly two hours after an invalid block was sequenced and transactions, deposits and withdrawals were temporarily stalled.
- Engineers reported they isolated a consensus problem that allowed the invalid block to be sequenced and said the root cause remains under investigation.
- Block production and transaction processing resumed after the team restored sequencing and internal nodes began syncing.
- Base advised ecosystem node operators to restart their nodes to restore synchronization and said apps and infrastructure were coming back online as nodes resynced.
- The outage happened hours before Base’s Beryl hardfork and follows prior reliability issues including May withdrawal delays and an August 2025 disruption, raising scrutiny of the network’s operational resilience.
