Base's mainnet [halted block production](https://x.com/buildonbase/status/2070182021746294932) today, just hours before the activation of its second major network upgrade, [Beryl](https://blog.base.dev/introducing-base-beryl). Block building has [since been restored](https://x.com/buildonbase/status/2070203623854772355), Beryl has commenced, and Base the team confirmed no funds were at risk throughout the incident.

### **What's the Scoop?**
- **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.
