Overview

• Solana Status reported the final tally on Sept. 2: 98.27% Yes, 1.05% No, 0.36% Abstain, with 52% of total stake participating, confirming SIMD-0326 passed.
• Alpenglow replaces Proof-of-History and TowerBFT with two new components, Votor and Rotor, marking a fundamental redesign of the protocol’s consensus and data flow.
• Votor targets block finality in roughly 100–150 milliseconds, a sharp improvement from today’s ~12.8 seconds, using direct validator voting for near-instant confirmations.
• Rotor is slated for a later phase to minimize inter-validator data transfers and reduce gossip traffic, aiming to boost performance for high-demand uses like DeFi and gaming.
• Implementation planning is underway for validator software upgrades, testing, and activation timelines, with the design outlining a “20+20” resilience model and moving validator voting off-chain with new fee mechanics.
