Anza has launched the Alpenglow consensus upgrade on the Solana community testnet, expanding on the earlier reported Alpenswitch milestone. The new framework allows validators to switch from Solana’s current Proof-of-Stake, Proof-of-History and TowerBFT architecture to Alpenglow on the testnet. Anatoly Yakovenko said mainnet deployment could come as early as next quarter if testing goes well, adding a potential rollout timeline to the upgrade effort.
