Base mainnet down due to consensus problem with invalid block

The Base network is temporarily down due to a consensus problem that causes an invalid block to be processed. After block 47806542, new blocks stop appearing, disrupting deposits, withdrawals and overall block production on the mainnet. The team is working on a fix and investigating the root cause.

What exactly is going wrong on Base

According to an incident report on Base’s status page, the team has identified a consensus issue that causes an invalid block to be sequenced. This blocks the creation of new blocks after block number 47806542. Both deposits and withdrawals are currently disrupted, as is the block software for clients.

The internal sequencer and nodes have now been partially restored. The team is focusing on resuming block propagation to the network while continuing to isolate the exact cause of the problematic block. A full recovery has not yet been confirmed.

What users can expect now

For users of the Base network, this means transactions are temporarily not being processed. Anyone wishing to deposit or withdraw funds via Base should wait until the network is fully operational. Updates on the incident can be followed on Base’s status page.

Base is a layer 2 network built by Coinbase on the Ethereum blockchain. Outages like this once again highlight the dependency on a central sequencer. The team says it is continuing to debug and will keep the community informed of new developments.
