Solana sets Oct. 21 for Alpenglow upgrade targeting 150-millisecond finality
Solana has scheduled the 'Alpenglow' network upgrade for October 21, aiming to achieve transaction finality in approximately 150 milliseconds. The update replaces the existing TowerBFT system and moves validator votes off-chain, which may result in a significant drop in reported transaction counts.
Why it matters
This technical upgrade is designed to improve network efficiency and reliability for merchants and bridges, though it complicates how transaction volume is measured.

Alpenglow will replace TowerBFT and move validator votes off-chain, which could sharply reduce Solana’s reported transaction count without reflecting a decline in user activity. Validators must use Agave 4.3.0 for the migration, while Firedancer and Frankendancer operators will need to switch software temporarily. Solana has scheduled Oct. 21 for Alpenglow, a major upgrade aimed at making transactions irreversible in roughly 150 milliseconds by changing how the computers running the network agree on payments.
