Odaily Planet Daily: Solana's Alpenglow upgrade has been deployed on the devnet and testnet. The goal is to reduce transaction finality/settlement time from 12.8 seconds to about 150 milliseconds.

The upgrade changes how validators reach consensus and moves validator voting out of the block; even if user activity remains unchanged, the reported total transaction volume will decrease. The mainnet rollout time has not yet been determined, and the 150-millisecond target has not been consistently achieved in real-time market environments. (CoinDesk)
