Solana's proposed Alpenglow upgrade, developed by Anza, aims to overhaul its consensus protocol with Votor and Rotor, potentially reducing block finalisation time to 150 milliseconds.
The upgrade targets Web2-level speeds but does not address Solana's network outage issues tied to its reliance on a single validator client, Agave.
Anza's Alpenglow introduces Votor for block finalization and Rotor for data propagation, replacing TowerBFT and Proof-of-History systems to enhance performance.
Despite the performance improvements, Alpenglow will not resolve Solana's downtime risks caused by a single client dependency, with the network still vulnerable until the launch of a second client, Firedancer.
