日本のデモでsignal使われ始めたみたいだけど、現場でbitchatも試してほしいな。
ネパールのデモで活躍した、Bluetoothでインターネットを使わずに通信するチャットアプリ。暗号化されててテレメトリもない。
イランでネット遮断があったときにも流行ったみたい。

Bitchat (permissionlesstech/bitchat), pero pocos entienden el tremendo impacto de esa red alternativa y solo depende de cada uno de nosotros (citadinos, principalmente).

@Issamsaed90 التطبيق مبني على شبكة بلوتوث «mesh» بين الأجهزة القريبة، وهيك بيشتغل بدون إنترنت ولا شبكة موبايل 📡 فكرة ذكية خصوصًا وقت انقطاع الشبكات، والكود منشور على GitHub لأي حدا حابب يتعمق.

bitchat: bluetooth mesh chat, IRC vibes (36k stars)
What it does
All text below is quoted directly from the project README.
>A decentralized peer-to-peer messaging app with dual transport architecture: local Bluetooth mesh networks for offline communication and internet-based Nostr protocol for global reach. No accounts, no phone numbers, no central servers. It's the side-groupchat.
Features:
- Dual Transport Architecture: Bluetooth mesh for offline + Nostr protocol for internet-based messaging
- Location-Based Channels: Geographic chat rooms using geohash coordinates over global Nostr relays
- Intelligent Message Routing: Automatically chooses best transport (Bluetooth → Nostr fallback)
- Decentralized Mesh Network: Automatic peer discovery and multi-hop message relay over Bluetooth LE
- Private Message End-to-End Encryption: Noise Protocol for mesh, BitChat private envelopes for Nostr fallback
- IRC-Style Commands: Familiar /slap, /msg, /who style interface
- Universal App: Native support for iOS and macOS
- Emergency Wipe: Triple-tap to instantly clear all data
- Performance Optimizations: LZ4 message compression, adaptive battery modes, and optimized networking
Bluetooth Mesh Network (Offline):
- Multi-hop Relay: Messages route through nearby devices (max 7 hops)
- No Internet Required: Works completely offline in disaster scenarios
>This project is released into the public domain.
