Planning to "revolutionize" the Solana consensus mechanism, what is the origin of Anza?

On May 20, 2025, Anza, a company founded by Solana Labs executives and core engineers, announced a plan hailed as the "biggest transformation in Solana's core protocol history" - Alpenglow. This entirely new architecture will replace the existing TowerBFT consensus mechanism and historical proof timestamp system with Votor and Rotor components, aiming to make Solana faster, more stable, and competitive with internet infrastructure as a high-throughput Layer-1 blockchain. The two most important points of this Solana transformation are as follows: • Votor Consensus Mechanism Innovation: Votor replaces TowerBFT, adopting a more efficient direct communication mode with a parallel voting mechanism to accelerate block confirmation. When 80% of staked nodes agree, blocks can be confirmed in one round; when the staking ratio is 60%, two rounds of confirmation are needed. This design reduces block processing time to 100-150 milliseconds, significantly improving transaction speed and network scalability. • Rotor Block Propagation Optimization: Rotor improves the Turbine system by using single-layer relay nodes and stake-based bandwidth optimization to enhance block propagation efficiency. Combined with erasure coding technology, Rotor ensures block data can be quickly distributed and reconstructed from partial data fragments, further enhancing Solana network's performance and stability. [The rest of the translation follows the same professional and accurate approach, maintaining the original structure and technical nuances.]
