🏎️ Solana Cuts Finality From 12.8 Seconds to 150 Milliseconds
Next Wednesday, Solana rips out the engine and drops in a new one while the car is doing 70 on the highway.
On October 21, around 15:00 UTC, Solana activates Alpenglow on mainnet, retiring the consensus mechanism it has run on since launch. Finality drops from roughly 12.8 seconds to a target of about 150 milliseconds – 85 times faster. Anza, the core dev shop behind it, called it “18 months of work for a migration that happens in one slot.”
