Solana delays Alpenglow upgrade to October, aiming for 150ms finality from 12.8s today

Solana plans to replace its TowerBFT consensus with Alpenglow, targeting a finality time of about 150 milliseconds, significantly faster than the current 12.8 seconds. The upgrade, initially expected in September 2026, is now scheduled for October 2026 with the Agave 4.3 release. Alpenglow aims to improve transaction finality, which is crucial for exchanges and payments, by providing stronger certainty that transactions cannot be reversed. Testing and security reviews are ongoing, including a bug bounty program offering up to 50,000 SOL to ensure readiness before mainnet deployment.
