- Solana’s Alpenglow aims for 150ms block finality
- Governance voting starts in about 16 days
- SIMD 326 upgrade brings major consensus changes
Solana has launched the community governance process for its latest proposal — SIMD 326, also known as Alpenglow. This significant upgrade aims to reduce block finality time to just 150 milliseconds, a massive leap that could set a new benchmark for high-performance blockchains.
Alpenglow is designed to make Solana even faster and more reliable. Block finality is the point at which a transaction is permanently recorded on the blockchain and cannot be changed. With this proposal, Solana is moving closer to real-time blockchain confirmations, which could dramatically improve user experience across decentralized applications, DeFi, and gaming.
What Alpenglow Brings to Solana
The SIMD 326 proposal introduces changes to the consensus mechanism that optimize how validators reach agreement on new blocks. According to Solana developers, these improvements will help the network finalize transactions in just 150 milliseconds, compared to the already fast speeds Solana is known for.
This upgrade also reflects Solana’s continuous push for scalability and efficiency, making it more attractive to developers and enterprises needing high-throughput infrastructure.
Community Involvement and the Road Ahead
The proposal has now entered its community governance phase, where validators, stakeholders, and developers can discuss and provide feedback. A formal vote is expected in approximately 16 days, which will determine whether the network adopts Alpenglow.
This move highlights Solana’s commitment to decentralization, allowing the community to shape the protocol’s future. If approved, the Alpenglow upgrade could roll out shortly after, putting Solana at the forefront of blockchain speed and performance.
