Online reports that Anza, a development studio spun out of Solana Labs, announced what they called "the biggest change in the history of Solana's core protocol." According to the announcement, this high-throughput Layer1 blockchain will usher in a newly designed underlying architecture called Alpenglow. Anza's Quentin Kniep, Kobi Sliwinski and Roger Wattenhofer wrote in a white paper released Monday: "We believe the release of Alpenglow will be a turning point for Solana. Alpenglow is not only a new consensus agreement, but also the biggest change in Solana's core agreement ever." The upgrade will replace Solana's existing TowerBFT proof-of-stake consensus mechanism and historical proof-of-stake timestamp system with new components called Votor and Rotor.
