Solana's Alpenglow Upgrade Goes Live Oct. 21 With Finality Cut to 150ms
- —Alpenglow is scheduled to activate on mainnet-beta on Oct. 21, 2026, at ~14:50 UTC
- —Finality drops from 12.8 seconds to roughly 150 milliseconds, a ~99% improvement
- —Votor replaces onchain validator voting with direct validator-to-validator consensus
- —The switch to Votor requires 82% of staked SOL; Rotor has no activation date yet
Why it matters: Faster finality strengthens Solana's case in payments and DeFi, though SOL trades near $106, about 64% below its all-time high.
