Historic Day for Solana (SOL): Alpenglow Network Can Speed Up by Up to 40 Times! Here Are the Details

Described as Solana's biggest technical change since 2020, Alpenglow aims to reduce transaction completion time from six seconds to approximately 150 milliseconds. Solana is preparing to activate the Alpenglow update on the mainnet on October 21st, an update that significantly changes how the network reaches consensus among validators. If the update is successful, transaction finalization time could drop from approximately six seconds to as little as 150 milliseconds. In the current system, validators' votes are written directly to the blockchain like other transactions. A sufficient number of votes must accumulate on the chain for a transaction to be considered irreversible.
