Solana prepares for Alpenglow upgrade targeting 150 ms transaction finality
Image: Crypto.newsSolana has set October 21 for its Alpenglow consensus upgrade. The upgrade aims for roughly 150‑millisecond transaction finality, though actual times may vary. It replaces the current voting and finality logic with a design from Anza. Validators must run updated software and fund accounts before the change. RPC nodes may receive finality data later than consensus participants. The code has undergone public security review and a bug bounty.
Key points
- Solana's Alpenglow upgrade is scheduled for October 21.
- The upgrade targets transaction finality of roughly 150 milliseconds as an engineering objective.
- It replaces the existing consensus and voting mechanism with a new design developed by Anza.
- Validators need to adopt compatible software and manage the network transition.
Why it matters
A faster finality target could reduce confirmation times for users, while the consensus change may affect how transaction metrics are reported. Successful implementation depends on validator readiness and network stability.
What's unclear
Actual finality times on mainnet after the upgrade remain unknown.
The exact timing of RPC node finality updates relative to validators is not confirmed.
