On June 25, Base mainnet experienced a consensus issue that caused an invalid block to be sequenced, halting all block production after block 47806542. Mainnet deposits, withdrawals, block production, and client software operations were all disrupted by the incident.
The internal sequencer and nodes have partially recovered, but full block propagation has not yet been restored. The root cause of the consensus issue remains under active investigation by the Base team, with no timeline provided for complete recovery.
