## bitchat
|
||||
|

A decentralized peer-to-peer messaging app that works over Bluetooth mesh networks. No internet required, no servers, no phone numbers. It's the side-groupchat.
|
||||
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
|
||||
- **Privacy First**: No accounts, no phone numbers, no persistent identifiers
|
||||
- **Private Message End-to-End Encryption**: [Noise Protocol](http://noiseprotocol.org)
|
||||
- **Private Message End-to-End Encryption**: [Noise Protocol](http://noiseprotocol.org) for mesh, NIP-17 for Nostr
|
||||
- **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
|
||||
|
||||
|
||||
## [Technical Architecture](https://deepwiki.com/permissionlesstech/bitchat)
|
||||
|
||||
### Binary Protocol
|
||||
bitchat uses an efficient binary protocol optimized for Bluetooth LE:
|
||||
- Compact packet format with 1-byte type field
|
||||
- TTL-based message routing (max 7 hops)
|
||||
- Automatic fragmentation for large messages
|
||||
- Message deduplication via unique IDs
|
||||
BitChat uses a **hybrid messaging architecture** with two complementary transport layers:
|
||||
|
||||
### Mesh Networking
|
||||
- Each device acts as both client and peripheral
|
||||
- Automatic peer discovery and connection management
|
||||
- Adaptive duty cycling for battery optimization
|
||||
### Bluetooth Mesh Network (Offline)
|
||||
|
||||
- **Local Communication**: Direct peer-to-peer within Bluetooth range
|
||||
- **Multi-hop Relay**: Messages route through nearby devices (max 7 hops)
|
||||
- **No Internet Required**: Works completely offline in disaster scenarios
|
||||
- **Noise Protocol Encryption**: End-to-end encryption with forward secrecy
|
||||
- **Binary Protocol**: Compact packet format optimized for Bluetooth LE constraints
|
||||
- **Automatic Discovery**: Peer discovery and connection management
|
||||
- **Adaptive Power**: Battery-optimized duty cycling
|
||||
|
||||
### Nostr Protocol (Internet)
|
||||
|
||||
- **Global Reach**: Connect with users worldwide via internet relays
|
||||
- **Location Channels**: Geographic chat rooms using geohash coordinates
|
||||
- **290+ Relay Network**: Distributed across the globe for reliability
|
||||
- **NIP-17 Encryption**: Gift-wrapped private messages for internet privacy
|
||||
- **Ephemeral Keys**: Fresh cryptographic identity per geohash area
|
||||
|
||||
### Channel Types
|
||||
|
||||
#### `mesh #bluetooth`
|
||||
|
||||
- **Transport**: Bluetooth Low Energy mesh network
|
||||
- **Scope**: Local devices within multi-hop range
|
||||
- **Internet**: Not required
|
||||
- **Use Case**: Offline communication, protests, disasters, remote areas
|
||||
|
||||
#### Location Channels (`block #dr5rsj7`, `neighborhood #dr5rs`, `country #dr`)
|
||||
|
||||
- **Transport**: Nostr protocol over internet
|
||||
- **Scope**: Geographic areas defined by geohash precision
|
||||
- `block` (7 chars): City block level
|
||||
- `neighborhood` (6 chars): District/neighborhood
|
||||
- `city` (5 chars): City level
|
||||
- `province` (4 chars): State/province
|
||||
- `region` (2 chars): Country/large region
|
||||
- **Internet**: Required (connects to Nostr relays)
|
||||
- **Use Case**: Location-based community chat, local events, regional discussions
|
||||
|
||||
### Direct Message Routing
|
||||
|
||||
Private messages use **intelligent transport selection**:
|
||||
|
||||
1. **Bluetooth First** (preferred when available)
|
||||
|
||||
- Direct connection with established Noise session
|
||||
- Fastest and most private option
|
||||
|
||||
2. **Nostr Fallback** (when Bluetooth unavailable)
|
||||
|
||||
- Uses recipient's Nostr public key
|
||||
- NIP-17 gift-wrapping for privacy
|
||||
- Routes through global relay network
|
||||
|
||||
3. **Smart Queuing** (when neither available)
|
||||
- Messages queued until transport becomes available
|
||||
- Automatic delivery when connection established
|
||||
|
||||
