Solana Alpenglow vote passes with 98% approval
Solana stakers have overwhelmingly approved the proposed Alpenglow upgrade, clearing a major governance milestone and setting the network on a path toward a consensus overhaul. The SIMD-0326 proposal passed with 98.27% voting in favor, 1.05% against and 0.69% abstaining, with roughly 52% of stake participating, according to the network status report published on September 2, 2025. The result marks broad community support for a technically ambitious upgrade.
Alpenglow is a consensus-focused upgrade designed to radically speed up transaction finality. If implemented, the change aims to reduce finality times from about 12 seconds to roughly 150 milliseconds — a roughly 100x improvement — by replacing two core components of Solana’s current stack. The proposal introduces Votor, which will supplant Tower Byzantine Fault Tolerance to accelerate validator agreement, and Rotor, which will replace Proof-of-History’s timestamping with a new data dissemination model to cut the time nodes need to agree on network state.
Key facts:
- Proposal: SIMD-0326
- Vote result: 98.27% for, 1.05% against, 0.69% abstain
- Participation: ~52% of stake
- Target finality improvement: ~12s → ~150ms (~100x)
The upgrade has attracted bullish sentiment across the ecosystem given its potential to boost throughput and responsiveness for DeFi, NFTs and other on-chain applications. At the same time, the scale of the consensus changes means implementation will require careful coordination, extensive testing and validator upgrades to avoid disruption.
With the governance vote complete, the network now moves into the next phase toward enactment and testing.
Developers, validators and projects building on Solana will be watching closely as the team works to translate the community’s mandate into a secure, production-ready upgrade that can deliver the promised gains in speed and scalability.
