Solana’s Alpenglow upgrade went live on mainnet-beta on Oct. 21, cutting transaction finality from 12.8 seconds to 150 milliseconds in its largest change. Solana completed its largest consensus overhaul since the network’s March 2020 launch when core engineering firm Anza activated the Alpenglow protocol on mainnet-beta at slot 459,653,000 around 14:00 UTC on Wednesday, Oct. 21, according to a statement shared with The Block and Anza’s own announcement. The upgrade retires TowerBFT, the consensus mechanism Solana has used since genesis, and reduces the time for a transaction to become irreversible from about 12.8 seconds to roughly 150 milliseconds.
