Solana’s Alpenglow upgrade targets October 21 for 150ms finality

Alpenglow, Solana ’s most significant consensus upgrade, is scheduled to launch on the mainnet on October 21, aiming for a substantial reduction in transaction finality time to 150 milliseconds. This upgrade, announced via social media, seeks to replace the existing TowerBFT voting layer with direct validator votes and aggregate certificates. Although this announcement marks a major milestone for Solana, official documentation has yet to confirm the October 21 activation date. The anticipated upgrade is expected to enhance network performance significantly, potentially impacting Solana’s competitive position.
