Summary
- Solana’s Alpenglow upgrade, which aims to cut transaction settlement time to about 150 milliseconds from 12.8 seconds, is now active on its devnet and testnet.
- The upgrade changes how validators reach agreement and will remove validator votes from blocks, reducing reported transaction totals even if user activity remains unchanged.
- Alpenglow’s mainnet launch has not been scheduled, and its speed target has yet to be sustained under live-market conditions.
