## bitchat
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.

## License

## 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) for mesh, NIP-17 for Nostr
- **Private Message End-to-End Encryption**: [Noise Protocol](http://noiseprotocol.org)
- **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)
BitChat uses a **hybrid messaging architecture** with two complementary transport layers:
### 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
### 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
### Mesh Networking
- Each device acts as both client and peripheral
- Automatic peer discovery and connection management
- Adaptive duty cycling for battery optimization

## Setup
### Option 1: Using XcodeGen (Recommended)
1. Install XcodeGen if you haven't already:
```bash
brew install xcodegen
```
2. Generate the Xcode project:
```bash
cd bitchat
xcodegen generate
