Alpenglow Solana upgrade begins activation, targeting 150ms transaction finality

Solana’s Alpenglow upgrade entered its mainnet activation process on October 21, with the Solana Foundation listing its activation switch as active. The change introduces a new way for the computers running the network to agree that transactions are final. For users, the goal is to have a shorter wait before a payment is settled. Alpenglow wants about 150 milliseconds, or 0.15 seconds, this is instead of the 12.8 seconds that the previous system has. What faster finality means for users A transaction appearing in a wallet does not mean it has become final.
