Coinbase's Base resumes block production after 2-hour outage

Summary

Base, Coinbase’s blockchain, went offline for nearly two hours because of a consensus problem that produced an invalid block and stopped new blocks from being created. The team first reported unhealthy block production, then isolated the issue and later said block building had recovered and ecosystem infrastructure was syncing normally. It said all funds were safe and promised a full post-mortem. The outage was rare for a major chain and came just before a scheduled Base upgrade, Beryl, which aimed to speed withdrawals and add support for new token standards for real-world assets and stablecoins.
