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

TechFlow reports: On September 23, according to CoinDesk, Solana has tested the Alpenglow upgrade on its public testnet, aiming to reduce transaction finality from approximately 12.8 seconds to 150 milliseconds. This upgrade will replace TowerBFT with the Votor voting protocol, enabling validators to confirm blocks through one or two rounds of direct voting. The current test only supports the Agave 4.3 client developed by Anza, with Firedancer and Frankendancer under Jump Crypto not yet integrated; the mainnet launch date remains undetermined.
