What Happened
Solana announced that the Alpenglow upgrade will go live at the start of epoch 1064 on Wednesday, October 21, around 15:00 UTC, replacing the TowerBFT consensus with a faster voting protocol.
Why It Matters
The new protocol targets transaction finality of ~150 ms versus the current ~12.8 s, dramatically speeding up confirmations for payments, DeFi, and trading. On‑chain vote transactions will move off‑chain, so headline TPS numbers will drop even though real activity stays the same. Faster finality improves user experience and could boost capital inflows and positive sentiment toward SOL.
Trader takeaway: Prepare for a short‑term dip in reported TPS on Oct 21, but expect stronger long‑term demand for SOL as finality improves.
