MetaMesh

A high-performance, cross-platform cryptographic identity management system with post-quantum security using Dilithium signatures, deterministic key generation, and mesh networking capabilities.

Features

• Post-Quantum Cryptography - Dilithium2 signatures for quantum-resistant security
• Hardware Entropy Collection - Physical sensors (accelerometer, microphone, timing jitter) for true randomness
• Deterministic Key Generation - Reproducible keys from mnemonic phrases
• Cross-Platform Daemon - gRPC service for all platforms including microcontrollers
• Mesh Transport Layer - BLE, WiFi Direct, and LoRa support with automatic failover
• Multi-Target Support - CLI, mobile, embedded, and node implementations
• Human-Readable Mnemonics - Natural language seed phrases for key recovery

Transport Layer

MetaMesh automatically detects and uses available transport mediums:

• BLE (Bluetooth Low Energy) - Cross-platform mesh networking
• WiFi Direct - High-bandwidth peer-to-peer (planned)
• LoRa - Long-range, low-power communication (planned)

The daemon monitors transport availability and automatically switches between mediums:
