Solana's Alpenglow consensus upgrade activates October 21, replacing TowerBFT with Votor to achieve ~150ms transaction finality.
Tech & Launches ·
Solana's Alpenglow consensus upgrade is scheduled to activate on mainnet on October 21, replacing the TowerBFT consensus mechanism with Votor and targeting transaction finality of roughly 150 milliseconds. The upgrade will alter how validator votes are recorded on-chain, moving them outside the standard transaction pipeline. As a result, reported transaction counts may decline following activation without indicating an actual decrease in network usage. Faster finality could enhance Solana's appeal for applications sensitive to latency, though the change in how transactions are counted means on-chain metrics will require careful interpretation in the upgrade's aftermath.
