With Solana’s Alpenglow upgrade expected on October 21, 2026, 151 validators holding 20.3% of the network’s stake have been flagged as unprepared for the transition.

The upgrade aims to cut finality time from 12.8 seconds to approximately 150 milliseconds by replacing the TowerBFT mechanism with an aggregated BLS signature system. This 20.3% figure actually reflects progress compared to the earlier 45% of stake that was failing readiness checks.
