Flash: Base Pins Mainnet Halt on Consensus Fault; Sequencer, Nodes Partly Restored

Base said a consensus issue led its sequencer to produce an invalid block, halting new block production after block 47806542. The incident disrupted mainnet deposits and withdrawals, block production, and client software. Base reported its internal sequencer and nodes have seen an initial recovery. The team is working to restore block propagation and continues to investigate the root cause.
