IT'S LIVE TODAY: Solana Activates Alpenglow - Biggest Upgrade Since 2020! 🚀
History is happening now. At Epoch 1064 today Oct 21 ∼14:50 UTC, Solana activates Alpenglow, replacing TowerBFT voting that has run since genesis.
What changes? Transaction finality drops from 12.8 seconds to just 150 milliseconds — 85x faster, nearly instant. Votor protocol replaces heavy vote transactions (∼500KB per slot) with off-chain aggregated BLS signatures (∼1,000 bytes).
Why it matters: Built by Anza, this unlocks real-time DeFi, payments, and gaming. No more waiting for finality. But risk remains — 151 validators holding 20.3% stake flagged as unprepared yesterday, and Firedancer clients not supported during migration.
SOL price at $106.7 up 1.95% on the news. After 6 testnet restarts, mainnet is ready.
Is Solana now the fastest L1 ever? Are you bullish?
