 ## 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.

 ## 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)
+### Mesh Networking
-
+- Each device acts as both client and peripheral
-- **Local Communication**: Direct peer-to-peer within Bluetooth range
+- Automatic peer discovery and connection management
-- **Multi-hop Relay**: Messages route through nearby devices (max 7 hops)
+- Adaptive duty cycling for battery optimization
-- **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
