Solana launches Alpenglow upgrade public beta, aims to shorten transaction finality to 150 milliseconds

According to CoinDesk, Solana has been testing the Alpenglow upgrade on its public testnet, aiming to reduce transaction finality from approximately 12.8 seconds to 150 milliseconds. The upgrade will replace TowerBFT with the Votor voting protocol, enabling validators to confirm blocks through one to two rounds of direct voting. Currently, testing only supports the Agave 4.3 client developed by Anza, while Firedancer and Frankendancer under Jump Crypto have not yet been integrated. A mainnet launch date has not yet been confirmed.
