The Alpenglow mainnet launch for Solana, a consensus protocol overhaul aiming to reduce finality to 150 milliseconds, is not happening on the rumored date of September 28, 2026. Key Solana figures including co-founder Anatoly Yakovenko and Anza research head Roger Wattenhofer confirmed the protocol is still in public testing and not ready for activation.
This Wire brief sits within Fusion42's coverage of Crypto & Web3.
◆ ◆ The Wire takeaway
You cannot count on Solana's protocol upgrade happening soon, and any plans relying on faster finality need more patience. Your timelines for leveraging Solana’s speed improvements should be pushed back until the network is fully tested and stable.
