Key Takeaways Alpenglow consensus takes over about 5,000 slots, roughly 18 minutes, after the epoch starts. Votor targets finality of around 150 milliseconds, down from roughly 12.8 seconds under TowerBFT. Vote transactions will leave blocks, requiring transaction-count and TPS dashboards to set new baselines. October 21 starts the rollout, not the instant switch Solana Foundation’s Alpenglow documentation places the start of epoch 1064 at approximately 15:00 UTC on October 21, 2026. Because epoch timing can drift, that clock time is an estimate rather than a fixed activation moment.
