Solana’s Alpenglow launches on mainnet, targets 99% faster finality

Solana activated the Alpenglow network upgrade on its mainnet on Wednesday, October 21. This major consensus overhaul represents one of the most significant updates in the blockchain's history. By replacing the existing consensus mechanism, Alpenglow targets a 99% reduction in transaction finality times. This improvement seeks to provide users with near-immediate transaction settlement and more responsive applications, marking a substantial step forward in the overall performance and efficiency of the Solana network infrastructure.
