Anza Puts Solana’s Alpenglow Consensus Switch on the Mainnet Calendar for Oct. 21

Solana's developer Anza announced that the Alpenglow consensus protocol will launch on mainnet-beta on Oct. 21 at 14:50 UTC, replacing TowerBFT. Alpenglow, which reduces finality time to ~150ms, has been tested on testnet and devnet. The migration involves a 5,000-slot countdown and validator votes moving off-chain. Solana validators approved Alpenglow in September 2025, with over 98% in favor.
