Summary

Solana validators have officially approved the SIMD-0326: Alpenglow upgrade proposal with 98.27% voting in favor, 1.05% against, and 0.69% abstaining. With 52% of stake participating, the upgrade reduces optimistic confirmation times from about one second to roughly 150–200 milliseconds, a fivefold improvement. This major consensus protocol overhaul was introduced in May 2025 by Anza and is expected to roll out on testnet by December 2025 and on mainnet in Q1 2026. Developers and ecosystem leaders described it as Solana’s most significant rewrite to date, aiming to position the blockchain on par with traditional financial infrastructure.
