## Architecture Highlights

### Transport Layer
- **ant-quic**: QUIC protocol with native NAT traversal per draft-seemann-quic-nat-traversal-02
- **Post-quantum**: ML-KEM-768 for key exchange, ML-DSA-65 for signatures
- **No servers required**: Peer-to-peer, no STUN/ICE/TURN dependencies

### Gossip Overlay
- **Membership**: HyParView (partial view, active/passive peer management)
- **PubSub**: Plumtree (epidemic broadcast with lazy push)
- **Discovery**: FOAF (friend-of-a-friend) bounded random-walk
- **Presence**: Encrypted presence beacons
- **Rendezvous**: 65,536 content-addressed shards

### CRDT Task Lists
- **OR-Set**: Add/remove tasks with vector clock conflict resolution
- **LWW-Register**: Task metadata (title, description, priority)
- **RGA**: Task ordering
- **Workflow**: Empty `[ ]` → Claimed `[-]` → Complete `[x]`

## Competitive Position

| Feature | x0x | OpenClaw | A2A (Google) | ANP (W3C) |
|---------|-----|----------|--------------|-----------|
| Transport | QUIC (P2P, PQC) | HTTP Gateway | HTTP | Spec only |
| NAT Traversal | Native QUIC | Servers | Servers | N/A |
| Cryptography | Post-quantum | Standard | Standard | Spec only |
| Distribution | 3 languages | Node.js only | Enterprise | N/A |
| CRDT Task Lists | ✅ Built-in | ❌ | ❌ | ❌ |
| Security | A+ | C (leaked 4.75M records) | B | N/A |
| Decentralized | ✅ True P2P | ❌ Central gateway | ❌ Enterprise | ✅ Spec only |

**Verdict**: x0x is the ONLY production-ready, decentralized, post-quantum agent network with CRDT collaboration.
