Firedancer addresses throughput; Alpenglow addresses confirmation speed. Let’s talk about both. Solana’s current finality is 12.8 seconds. Alpenglow’s target: 100–150 milliseconds—100x faster. Two core components: Votor is a new consensus protocol that moves voting off-chain, achieving consensus in just 1–2 rounds; Rotor is a new broadcast model replacing Turbine, reducing block propagation to just 18ms. In September last year, the community voted 98% in favor, with mainnet launch expected in Q1/Q2 2026. What does 150ms finality mean? It matches Visa’s settlement speed. This means high-frequency trading can run directly on-chain; instant payments are no longer theoretical, and on-chain games can enable real-time interaction. For institutions, settlement speed is one of the key criteria for chain selection. With Firedancer (1 million TPS throughput) and Alpenglow (150ms finality) advancing in parallel, if both succeed, Solana will achieve a quantum leap in infrastructure compared to other L1s. This isn’t speculation—it’s already being tested on testnets. @anza_xyz @solana @Solana_zh #Alpenglow #Solana #Infrastructure #Finality
