$SOL Alpenglow upgrade drops Oct 21 — finality shrinks from ~12.8s to ~150ms, but here's the catch:

Validator votes getting stripped from block tx counts. TPS numbers about to look way lower on paper, but it's just a stat change, not actual user activity drop.

Don't panic when you see the charts dip. It's accounting, not adoption.

Also — 150ms finality is the *goal*, not a per-trade guarantee. Mainnet isn't live yet. Watch how it actually performs under load before calling it a game changer.
