Overview
Solana’s Alpenglow upgrade has reached public testing, where application teams can evaluate a design targeting a reduction in transaction finality from about 12.8 seconds to roughly 150 milliseconds before any live-network switch.

Why now
- Alpenglow has reached public developer testing, with reports saying it is running on both public test networks.
- The milestone gives developers a current environment to assess application compatibility.
Why it matters
- The reported target would materially shorten Solana transaction finality if implemented on the live blockchain.
- Application teams can test software against the upgrade before a live-network switch.
Evidence assessment
Recurring claims
- Alpenglow is active on public test networks and targets roughly 150-millisecond transaction finality.
How sources frame it
