Solana’s Alpenglow launches on mainnet, targets 99% faster finality

Solana’s first major consensus upgrade, Alpenglow, went live on mainnet around 1:54 pm UTC on Wednesday, according to the Solana Foundation’s Alpenglow dashboard.

Alpenglow seeks to reduce transaction finality by 99%, to roughly 150 milliseconds from about 12.8 seconds, according to the Solana Foundation’s July announcement.

The upgrade’s first phase, Votor, replaces the existing voting and finalization mechanism with direct validator voting and a certificate-based system designed to cut transaction finality to roughly 150 milliseconds. A later phase will introduce Rotor, a new block data-distribution protocol intended to replace Turbine.

Alpenglow is Solana’s first major consensus upgrade, replacing its current consensus model, TowerBFT. The upgrade’s 150-millisecond finality target seeks to introduce near-immediate transaction finality for users, which could mean faster payments, trade settlements and more responsive applications. 

Cointelegraph has approached the Solana Foundation for comment on Alpenglow’s finality measurements in testnet environments and its expected performance in real-world applications.

At press time, the Solana mainnet showed a 6.6-second transaction finality and a throughput of 4,721 transactions per second, according to the Alpenglow dashboard.
