Solana has activated Alpenglow consensus upgrade on the mainnet, replacing the original TowerBFT with Voter and the Turbine block propagation protocol with Rotor. After upgrading, the final block confirmation time has been shortened from about 12.8 seconds to about 150 milliseconds, directly reducing the waiting time for transaction confirmation; The transaction execution and SVM remain unchanged, with changes focused on the validator voting method, consensus mechanism, and the way consensus information is transmitted to downstream infrastructure.
