Post-Quantum Crypto
ML-KEM-1024 (key encapsulation), ML-DSA-87 (signatures), SHA3-512 (hashing), AES-256-GCM (symmetric). NIST Category 5 — all crypto runs in C, never in managed code.

DNA Library
The post-quantum C engine powering every DNA Protocol product. Modular, cross-platform, and built for security-critical applications.
Overview
One library, every platform
DNA Library (libdna) is a native C library that handles all cryptography, messaging, DHT operations, and local storage. Flutter, Android, and CLI tools connect through FFI bindings.
Modular Engine
Async task queue with domain modules: messaging & social (chats, groups, channels, wall), identity & security (keys, signing, wallet), network (DHT, presence, backup).
Cross-Platform
Compiles for Linux, Windows, Android. Flutter connects via dart:ffi, Android via JNI, CLI for automation. Same C code on every platform — zero per-platform forks.
Architecture
Domain-driven module design
Every operation goes through an async task queue. Modules register handlers for their domain. The thread pool executes concurrently, results arrive via callbacks — keeping the UI responsive.
Communication
E2E encrypted messaging with offline delivery and retry. Group chats with rotating GEK keys. Public channels and personal wall posts. Contact management with request/block flows.
Identity & Wallet
BIP-39 seed-based identity creation. Dilithium5 signing for all DHT operations. Multi-chain wallet (Cellframe, Ethereum, Solana, TRON) with DEX integration and in-chat transfers.
Network & Infrastructure
Nodus client SDK for DHT operations with connection pooling. Server-side presence system. DHT backup and sync. Background thread pool and lifecycle management (pause/resume on mobile).
Integration
Crypto stack & platform bindings
Post-Quantum Crypto Stack
All cryptographic operations use NIST-standardized algorithms. Classical algorithms are used only for blockchain compatibility.
- Key encapsulation: ML-KEM-1024 / Kyber1024 (FIPS 203)
- Signatures: ML-DSA-87 / Dilithium5 (FIPS 204)
- Hashing: SHA3-512 (FIPS 202)
- Encryption: AES-256-GCM + BIP-39 seed management
- Blockchain: secp256k1 (ETH/TRON), Ed25519 (Solana)
Platform Bindings
DNA Library compiles to a shared library (libdna.so / dna.dll). All business logic lives in C — platform layers are thin wrappers.
- Flutter: dart:ffi — async callbacks bridged to Futures and Streams
- Android: JNI bindings — engine in native thread, UI via callbacks
- CLI: Standalone binary for testing and automation
- Nodus SDK: Embedded DHT client with connection pooling and reconnection
