Solana starts testing upgrade that could cut finality from 12.8 seconds to 150 milliseconds

Why now

Thesis: Solana targets payment-grade speed to widen real usage

Catalyst to watch: Upgrade test results and mainnet rollout timing

Main risk: Upgrade may stall or fail in testing

Why it matters

Faster finality makes Solana payments and bridging more practical, potentially increasing on-chain usage and demand for SOL.

Details

Alpenglow would let exchanges, bridges and merchants treat payments as irreversible almost immediately.
