DNA-Messenger
Post-Quantum Secure Communication

DNA-Messenger is the communication layer of the CPUNK protocol: a post-quantum messenger that uses DNA identities instead of phone numbers. All messages are E2E encrypted and transported via the post-quantum DHT network.

Most privacy preserving communication app in the world. Clients: Android, Linux, Windows (Beta) · iOS planned
Overview

What DNA-Messenger is designed to solve

Most messengers depend on central servers and classical cryptography. DNA-Messenger focuses on three things: identity, quantum safety, and E2E encrypted DHT transport.

Core concept

Identity-first, post-quantum messenger

DNA-Messenger uses your DNA identity (generated from your seed/keys, used across all your wallets) as the addressing layer. Messages are end-to-end encrypted using NIST-selected post-quantum algorithms and transported via the post-quantum DHT network (Nodus), with support for offline delivery via distributed storage.

  • No phone numbers or email addresses required.
  • No central servers – fully decentralized architecture.
  • Built for long-term security against future quantum attacks.
Security

NIST Category 5 encryption stack

DNA-Messenger uses Kyber1024 + Dilithium5 (NIST Category 5 – maximum quantum resistance), AES-256-GCM, and SHA3-512 to protect session keys, message contents, and identities. Uses only 20 bytes header (metadata) and collects no personal information.

Topology

DHT transport with offline delivery

All messages are transported via the post-quantum DHT network (Nodus). Messages are stored in distributed mailboxes with 7-day TTL so they can be retrieved later – fully decentralized, no central servers.

Architecture

How DNA-Messenger works

High-level workflow

DNA-Messenger is fully decentralized – no central servers. All communication flows through the post-quantum DHT network (Nodus).

  • Address contacts by DNA identity – no phone numbers or emails needed.
  • Your client locates the recipient via the DHT network and establishes session keys using post-quantum key exchange (Kyber1024).
  • Messages are E2E encrypted (AES-256-GCM) and transported through the DHT. Only 20 bytes of header metadata – no personal data collected.
  • Offline messages are stored in distributed mailboxes across DHT nodes with 7-day TTL.
  • When the recipient comes online, their client retrieves and decrypts messages locally.

Modern messaging convenience with NIST Category 5 post-quantum security – built for a world where quantum computers exist.

Usage

Who DNA-Messenger is for

DNA-Messenger is for privacy maximalists and communities who want secure communication without compromise. We can't collect anything even if we wanted to – there are no central servers, no accounts, nothing to store. Your identity and messages stay yours — protected for the future.

Technical users & builders

Developers who want to integrate post-quantum messaging into their own apps, tools, or bots using DNA identities as the addressing layer.

Communities & DAOs

Groups that need communication channels which are not tied to Big Tech accounts and are resistant to large-scale surveillance or deplatforming.

High-sensitivity environments

Users and organizations that want to stay ahead of the curve on quantum-era threats and avoid harvesting of encrypted traffic today that could be decrypted tomorrow.

Clients
