Solana’s Alpenglow Hits Second Testnet, 100ms Finality in Sight

Solana's Alpenglow upgrade activated on testnet Sept. 24 and devnet Sept. 25, replacing TowerBFT with Votor and targeting transaction finality of 100-150 milliseconds. Co-founder Anatoly Yakovenko said, 'You are not ready for this.' However, those speeds remain unproven under full mainnet conditions.
