Solana Tests Upgrade Cutting Finality From 12.8 Seconds to 150 Milliseconds

Solana $SOL is testing an upgrade called Alpenglow that could reduce transaction finality from 12.8 seconds to 150 milliseconds, enabling exchanges, bridges and merchants to treat payments as irreversible almost immediately. The enhancement addresses a key competitive disadvantage versus traditional payment rails and Ethereum Layer 2 solutions.

This performance leap could unlock real-time settlement applications for decentralized trading and merchant payments, potentially attracting institutional capital into Solana's ecosystem.
