Solana’s Alpenglow launches on mainnet, targets 99% faster finality
Summary
Solana’s Alpenglow consensus upgrade went live on mainnet Wednesday at about 1:54 pm UTC. Its first phase, Votor, replaces the existing voting and finalization system with direct validator voting and certificates, targeting transaction finality of roughly 150 milliseconds instead of about 12.8 seconds. A later phase is expected to add Rotor, a new data-distribution protocol. At the time reported, the dashboard showed 6.6-second finality and throughput of 4,721 transactions per second. The upgrade is intended to improve responsiveness for payments, trading and applications; its real-world performance remains to be assessed.
