Solana has started testing its proposed Alpenglow consensus protocol upgrade on a community test cluster. The move marks a key step toward a potential mainnet rollout later this year.
Solana developer Anza announced on May 11 that Alpenglow is now live on the community test cluster. The upgrade allows validators to test a transition from the current Proof-of-History and TowerBFT system to a new architecture designed for faster block confirmation.
