Woofun AI reports that Base experienced a network outage today caused by a consensus bug triggered by a single invalid block. Block generation ceased after height 47806542, halting the network for nearly two hours. Because Base relies on a single sequencer architecture, the error stopped all activity with no backup producers to bypass the fault. Users could not transact, liquidate, or withdraw during the downtime. Recovery required manual restarts by node operators to resume synchronization. This follows a similar 33-minute freeze in August last year due to a sequencer switching failure, underscoring the centralization risks of single points of failure in L2 networks.
