Base's mainnet halted block production today, just hours before the activation of its second major network upgrade, Beryl. Block building has since been restored, Beryl has commenced, and Base the team confirmed no funds were at risk throughout the incident.
• The stall: Block production on Base went awry starting around 16:03 UTC, with the chain ceasing to produce new blocks after block 47,806,542. The Base team identified a consensus problem in which an invalid block was sequenced, preventing ensuing blocks from being built atop it.
• The recovery: Block sequencing resumed by 17:51 UTC, and by 17:58 UTC the team confirmed everything had returned to normal and that a full post-mortem report on the incident was planned pending an investigation.
• Beryl on schedule: As the dust settled, Base successfully kicked off the Beryl hardfork, which activated at 18:00 UTC today as planned. Notably, Beryl brings with it a series of headline changes, including B20, a new native token standard built directly into Base nodes.
• Zooming out: A short stall with no funds risked and transparent communication throughout is a clean, applaudable resolution. We'll have to wait and see whether the post-mortem surfaces any connection to Beryl's activation prep, but for now the two events appear purely coincidental.
