Solana Alpenglow Upgrade Enters Second Public Testnet

TechFlow reports that on September 26, according to CoinDesk, the Solana core consensus upgrade project Alpenglow has officially advanced to its second public testnet phase.

This upgrade aims to significantly reduce the existing network's transaction settlement latency from approximately 12.8 seconds to 150 milliseconds, achieving near-real-time transaction finality.

This update will replace the original TowerBFT consensus flow, introducing a completely new Votor voting mechanism to optimize block confirmation speed. Core developer Anza described this version as "the largest consensus architecture adjustment in Solana's history" in a technical note, while developers are currently utilizing the testnet for performance verification.

Official sources indicated that this node upgrade primarily caters to the settlement speed requirements for high-frequency trading and payment scenarios. Subsequent testing will continue to collect network data in preparation for the upcoming mainnet hard fork deployment.
