Bitchat Demo: Calle
summary
Bluetooth mesh chat that sends messages peer‑to‑peer via Bluetooth and moves Bitcoin value using Cashu Chaumian e‑cash (and Lightning where available); demo shows an Android→iOS transfer over Bluetooth that is instant, near‑free and sometimes fully offline, with one device online suffices and cross‑platform (Android/iOS) support. App has real‑world spikes in unrest (Nepal, Jamaica where it hit #2 in app stores), claims untraceable like cash, and requires trusting a mint for e‑cash issuance.
