- Alpenglow upgrade receives 98% support in governance vote.
- Transaction finality to be cut to 150 milliseconds, rivaling Web2 responsiveness.
On September 2, 2025, the Solana community approved the Alpenglow consensus protocol upgrade with overwhelming support, according to reports from TradingView, CryptoSlate, and Blockworks. The proposal garnered 98% approval, with 52% of total staked tokens participating in the vote.
This upgrade marks a significant milestone for Solana, positioning it as one of the fastest blockchain networks in existence. The Alpenglow upgrade will slash transaction finality from over 12 seconds to a lightning-fast 150 milliseconds, a change that aims to deliver seamless user experiences and attract broader adoption for high-performance applications.
The upgrade introduces two major architectural changes. First, a revolutionary consensus algorithm named “Votor” will replace Solana’s current TowerBFT mechanism to achieve ultra-fast transaction confirmation. Second, “Rotor” will replace the existing proof-of-history system, a change that streamlines validator communication and reduces data transfer times. Together, these innovations promise to enhance network efficiency while maintaining robust security and scalability.
