Solana sets Oct. 21 for Alpenglow upgrade targeting 150-millisecond.
The switch will replace Solana’s existing validator voting system, remove vote transactions from blocks and could sharply change headline transaction counts even if user activity stays flat. Solana has scheduled Oct. 21 for Alpenglow, a major upgrade aimed at making transactions irreversible in roughly 150 milliseconds by changing how the computers running the network agree on payments. The updated timetable published by the Solana Foundation sets a date for replacing.
