Solana Activates Alpenglow Upgrade
Solana has activated its Alpenglow consensus upgrade on mainnet, reducing transaction finality from 12.8 seconds to approximately 150 milliseconds. This upgrade was completed by the core engineering team Anza on October 21, replacing TowerBFT with a faster protocol. The change could enhance Solana's appeal for payment providers, trading platforms, and financial institutions requiring faster transaction guarantees.
