Solana begins testing 'Alpenglow,' its largest-ever upgrade

Solana has officially begun testing its 'Alpenglow' upgrade, described as the largest consensus algorithm overhaul in the network's history, CoinDesk reported. Anza, one of Solana's core development teams, announced on X today that "Alpenglow is now live on the community test cluster." The move allows validator operators to test Solana's latest consensus system, which combines the existing Proof-of-Stake (PoS) mechanism with TowerBFT and Proof-of-History. According to CoinDesk, the upgrade focuses on replacing major components of the Solana blockchain with a redesigned framework. This is intended to enable validators to communicate and scale blocks more quickly and efficiently, with the ultimate goal of reducing transaction finality times from several seconds to near real-time.
