TechFlow News: On May 11, according to CoinDesk, Solana core developer Anza announced that the Alpenglow consensus upgrade has officially gone live on the community testnet cluster, enabling validators to begin testing the migration transition—from the existing Proof-of-History and TowerBFT mechanisms—to the new architecture (i.e., “Alpenswitch”). The new mechanism aims to significantly improve block confirmation efficiency, reducing transaction finality time from several seconds to near real-time. Anatoly Yakovenko, co-founder of Solana, previously stated at Consensus Miami 2026 that, if testing proceeds smoothly, Alpenglow could be deployed to the mainnet as early as next quarter.
