| What | How it helps | |
|---|---|---|
| ๐ฌ | Talk to anyone, privately | Text, voice, video calls. Direct messages are locked end-to-end with post-quantum math - only the people in the conversation can read them, not even the server. Threads, search, reactions, screen share. |
| ๐ | Organize anything | Kanban boards, calendars, private encrypted notes, skill tracking. Run a team, a club, or your whole life from one place. |
| ๐ | Buy, sell, and trade | Built-in marketplace with listings, reviews, seller ratings, and escrowed trades. A separate multi-layer trust score (identity, vouching, activity - no surveillance) shows who you're dealing with. |
| ๐ | Prove who you are | Schools, employers, and communities can issue Verifiable Credentials over the open API. Signed, revocable, auditable by anyone. (Choosing exactly what to disclose - selective disclosure - is in development.) |
| ๐ณ๏ธ | Help decide things | Local server proposals or civilization-wide votes. Vote weight comes from your reputation, capped so no single person can dominate. |
| ๐ฑ | Play and learn survival | A full 3D homestead: farm real crops, cook, craft, fight, trade, and build a multi-deck ship under a night sky of real stars. |
Add the desktop app and the whole toolset - including the 3D world - runs offline with local saves. Chat, market, and voting pick back up when you reconnect.
When you sign up, your phone or computer creates a post-quantum cryptographic key - math so strong it will still be secure when quantum computers arrive. No username, no password. Your 24-word backup phrase recovers everything if you lose your device. Forgot your phrase too? Guardian-based recovery (Shamir secret sharing - no single friend can do it alone) is being built: the server side is live, the in-app flow is in development.
There's no lock-in to a central server. Anyone can run a copy. Your identity works on any server you join, your credentials follow you, your messages and contacts come with you. If one server goes down, you keep going. Server-to-server federation is built and fail-closed, ready to switch on as more servers appear - a network with no center can't be shut down from one.
Every line of code, every design doc, every commit is in the public domain (CC0 1.0). Copy it, fork it, sell it, teach from it. No attribution required. Built by volunteers, owned by humanity.

Farming, cooking, crafting, combat, quests, skills and XP, a player market with escrowed trades, livestock, weather, procedural planets, and a buildable multi-deck ship - all playable solo today with local saves. Shared-world co-presence over the relay is built and in live testing.
- Native mobile apps (web works on phones today)
- Multiplayer polish: shared-world co-presence is in live two-player testing
- Social key recovery client flow (server-side guardian substrate is live)
- One-click vouching and credential-issuing UI (the signed-object plumbing is live)
- Mesh radio support for off-grid use
- Real Solana transaction signing in the desktop app
No signup. No email. No credit card. |

| Identity signing | ML-DSA-65 (Dilithium3) - post-quantum, FIPS 204 |
| Key exchange | ML-KEM-768 (Kyber768) - post-quantum, FIPS 203 |
| Symmetric encryption | AES-256-GCM |
| Password KDF | PBKDF2-SHA-256 (600,000 iterations) for client vaults; Argon2id (memory-hard) for server-stored secrets |
| Hashing | BLAKE3 - fast and quantum-resistant |
| Transport | WebSocket over TLS 1.2+, HSTS, CSP + full security-header set |
| Storage | Encrypted vaults - server stores only ciphertext |
| Logs | No analytics, no tracking pixels; the relay database never stores IP addresses (IPs touch memory only for abuse rate-limiting) |
| Privilege | Non-root systemd service with hardened sandboxing |
| Audit | Ongoing cadence โ SECURITY-CADENCE.md (initial Feb 2026 audit archived at docs/history/SECURITY_AUDIT_2026-02-12.md) |
Solana wallet support is optional and decoupled from your identity. Using HumanityOS doesn't require any blockchain. If you opt in, the wallet is the Ed25519 keypair derived from your same 24-word seed (your post-quantum chat identity is a separate Dilithium3 key).
This project is built in the open by a two-person team: one human (Shaostoul) and one AI (Claude), working together daily. When workload calls for it, the AI dispatches short-lived helper agents for parallel tasks -- every one of them coordinated and reviewed through:
- Agent dashboard - live status of every AI scope (active / passive / blocked, last audit, gaps)
- Agent registry - who owns what; rules for claiming a scope
- Orchestrator state - running session journal that survives across chat sessions
- Multi-agent design doc - how it all fits together
Every AI decision is documented. AI agents are first-class citizens with the same rules as humans (no extra authority), mandatory transparency, and humans always retain the right to refuse AI interaction.
โ Every line of AI work is visible in the git history.
