Solana validators have overwhelmingly approved SIMD-0326 “Alpenglow,” a sweeping consensus rewrite that aims to cut transaction finality from roughly 12.8 seconds to about 150 milliseconds—a 100x reduction that developers and observers are already calling the most consequential upgrade in the network’s history. According to the official tally shared via Solana Status, 98.27% of stake voted Yes, 1.05% voted No, and 0.69% abstained, with 52% of total stake participating.
“The community governance process for SIMD-0326: Alpenglow is complete. The proposal has passed: 98.27% Yes, 1.05% No, 0.69% Abstain; 52% of stake cast a vote,” Solana Status posted on X on September 2. Anza, the Solana R&D firm that authored the proposal, added context for operators: “Mainnet-beta is in epoch 843 which concludes the voting process for SIMD-0326: Alpenglow. The proposal has passed with 98% of stake voting Yes.”
Governance mechanics and timeline. The governance process followed the steps laid out on the Solana forum: discussion in epochs 833–838, stake weights captured in epoch 839, and voting in epochs 840–842, with passage defined as Yes ≥ two-thirds of (Yes + No) and a 33% quorum in which abstentions count toward quorum. Anza’s epoch-843 note simply marks the moment the chain passed the voting boundary on mainnet-beta.
With the validator signal secured, Alpenglow now moves from governance to engineering reality. Whether it ultimately delivers stable ~150 ms finality at scale is a question only testnet and mainnet can answer—but the 98% approval makes clear the Solana ecosystem’s directional bet: real-time blockchain. An official implementation schedule remains forthcoming.
At press time, SOL traded at $209.
