According to Foresight News, on May 19, Anza, a developer studio spun off from Solana Labs, introduced a new consensus layer protocol for Solana named Alpenglow. This protocol modifies the existing TowerBFT and PoH consensus mechanisms by incorporating new components, Votor and Rotor, to handle voting and block finality, and to enhance Solana's current block propagation protocol. Built on Turbine, Solana's version of sharding, it optimizes bandwidth usage through a single-layer relay node based on stake.


Roger Wattenhover, Anza's Head of Research, stated at Solana Accelerate that the new consensus mechanism will significantly reduce transaction finality time from the current 12.8 seconds to 150 milliseconds. Alpenglow has completed prototype testing and is expected to deploy on the testnet by mid-2025, with mainnet deployment anticipated later in the year following approval through Solana Improvement Documents (SIMD). Compared to the current Solana mainnet, Alpenglow simplifies architecture and optimizes data propagation efficiency, making it suitable for high-frequency trading and real-time payments.
