What is Solana Alpenglow?
Solana Alpenglow is a major consensus protocol upgrade (SIMD-0326) designed to reduce confirmation latency and increase resilience. The upgrade rearchitects consensus to deliver near-instant confirmations (~100–200ms) and improve throughput, aiming to bring Solana closer to traditional financial infrastructure speeds.
How did validators vote on SIMD-0326?
The proposal passed decisively: 98.27% Yes, 1.05% No, 0.69% Abstain, with roughly 52% of stake participating. Network validators completed governance voting on Tuesday, formally approving the Alpenglow implementation for staged rollout.

Alpenglow reduces optimistic confirmation times from around 1 second to ~150–200ms, according to Anza Lead Economist Max Resnick (quoted in industry reporting). That makes user experiences snappier and lets exchanges credit deposits faster than the current 12.8 second finality window.
Developers expect Alpenglow on testnet by the Solana Breakpoint conference in December, with a mainnet rollout planned for Q1 2026. These timelines come from the Solana research and Anza teams involved in the proposal.
Alpenglow reconfigures consensus to prioritize low-latency confirmations and resilience. Early statements and test runs indicate a target finality of 100–150ms, and internal developer tests have shown Solana reaching more than 100,000 transactions per second in controlled conditions.
