TechFlame News, according to CoinDesk, Solana core development team Anza has announced that a major consensus mechanism upgrade, codenamed Alpenglow, is now live on the community testnet. Validators can switch from the current Proof-of-Stake + Proof-of-History + TowerBFT architecture to the new consensus framework within the test cluster. The upgrade aims to significantly reduce transaction finality time and improve network responsiveness by restructuring validator communication and block confirmation processes. This testing marks the first time validators can execute the "Alpenswitch" migration in a real-world environment. Solana co-founder Anatoly Yakovenko previously stated that if testing goes smoothly, Alpenglow could be deployed to the mainnet as early as next quarter.
