Solana’s Alpenglow Proposal Set to Slash Finality Time
Solana’s Alpenglow proposal aims to cut block finality time to 150ms, promising faster transactions and improved user experience.

- Alpenglow proposes reducing Solana’s finality time to 150ms
- Strong community backing despite 62.6% votes uncast
- Voting ends on Sept 2, marking a key shift in Solana’s performance
The Solana Alpenglow Proposal (SIMD-0326) is poised to bring a major transformation to the Solana blockchain. Designed to drastically cut block finality time from 12.8 seconds to just 150 milliseconds, this proposal is a leap forward in network performance and user experience.
Currently marked as passed, Alpenglow is in the voting phase that spans Epochs 840 to 842. Although over 62% of votes are yet to be cast, the strong wave of early support from validators and developers suggests the proposal will hold through the end of the voting period, scheduled for September 2 at 1:40 PM UTC.
What Alpenglow Means for Solana
The goal of Alpenglow is clear: reduce finality time and boost network responsiveness. Finality is the point at which a transaction is considered irreversible. Bringing this down to just 150 milliseconds would make Solana one of the fastest blockchains in terms of transaction finality.
This has several implications:
- Improved User Experience: Faster confirmations mean smoother dApp performance, particularly in DeFi and gaming.
- Greater Network Efficiency: With lower latency, the network can handle real-time applications more effectively.
- Competitive Advantage: These changes position Solana more favorably against competitors like Ethereum and Avalanche.
Community Support and Future Outlook
Despite a significant number of uncast votes, the proposal’s current status and widespread support reflect the community’s confidence in Alpenglow. The proposal is part of Solana’s ongoing push to improve scalability and performance without compromising on decentralization or security.
If the final vote confirms its passage, users and developers can expect rapid deployment and testing phases soon after. Alpenglow may well mark a turning point in Solana’s mission to become the go-to blockchain for high-speed decentralized applications.
