Solana's Alpenglow Upgrade Introduces Rotor Protocol for Enhanced Network Efficiency

According to Foresight News, Anza, a company focused on Solana's development, announced the introduction of a new block propagation protocol called Rotor as part of the Solana Alpenglow upgrade. This single-layer repeater system replaces the multi-hop Turbine protocol, aiming to accelerate and unify network block delivery. Rotor enhances the network by fragmenting blocks, encoding them into shards, and broadcasting them globally through repeaters. This process ensures that blocks can be reconstructed with just half of the shards, reducing latency and balancing bandwidth usage. The protocol significantly decreases propagation time and variability, allowing nearly all validators to receive blocks simultaneously, which improves throughput and reduces the risk of forks caused by slow delivery or network delays. For developers, Rotor facilitates smoother real-time decentralized application (DApp) operations. For validators, it minimizes missed slots, reduces bandwidth waste, and makes network load more predictable. Previously, Foresight News reported that Anza released a white paper introducing the Alpenglow protocol. This protocol aims to replace Solana's TowerBFT consensus mechanism and historical proof timestamp system with the Votor and Rotor components.
