Solana's largest consensus upgrade Alpenglow has entered the community testing phase

According to CoinDesk, the Solana core development team Anza announced that a major consensus mechanism upgrade codenamed Alpenglow has gone live on the community test network, allowing validators to switch from the current Proof-of-Stake + Proof-of-History + TowerBFT architecture to the new consensus framework in the test cluster.

The upgrade aims to significantly shorten transaction finality time and improve network response efficiency by restructuring the validator communication and block confirmation process. This test marks that validators can now perform the "Alpenswitch" migration operation in a real environment. Solana co-founder Anatoly Yakovenko previously stated that if the testing goes smoothly, Alpenglow is expected to be deployed to the mainnet as early as next quarter.
