Solana is preparing to activate Alpenglow, aiming for transaction finality of 150 milliseconds. Solana is scheduled to activate the Alpenglow upgrade at 13:20 UTC today, equivalent to 20:20 Vietnam Time on October 21. Alpenglow is expected to significantly enhance Solana’s consensus mechanism, targeting a reduction in transaction finality time to approximately 150 milliseconds, down from the previous 12.8 seconds. If achieved, this goal could substantially improve transaction confirmation speeds, enhance user experience, and strengthen Solana’s competitiveness in areas such as cryptocurrency trading, DeFi, and on-chain payments. However, the 150-millisecond target is a performance goal and does not guarantee that all transactions will consistently achieve this finality time under real-world operating conditions. The actual effectiveness of Alpenglow will need to be further evaluated after the upgrade is deployed.
