> Post-quantum cryptography, consensus, identity, and blockchain integration

This section covers advanced ZAP features including post-quantum cryptography, distributed consensus, decentralized identity, and blockchain integration.

- [Post-Quantum Cryptography](https://docs.hanzo.ai/docs/zap/advanced/post-quantum): ML-KEM, ML-DSA, and hybrid handshakes
- [Corona Consensus](https://docs.hanzo.ai/docs/zap/advanced/corona): Threshold lattice-based signing
- [Agent Consensus](https://docs.hanzo.ai/docs/zap/advanced/agent-consensus): Voting-based response aggregation
- [W3C DID Support](https://docs.hanzo.ai/docs/zap/advanced/did): Decentralized identity integration
- [Lux Integration](https://docs.hanzo.ai/docs/zap/advanced/lux): Blockchain anchoring and staking

## Security Architecture

ZAP implements defense-in-depth security:

1. **Transport Layer**: Post-quantum hybrid TLS (X25519 + ML-KEM-768)
2. **Message Layer**: ML-DSA-65 signatures for authentication
3. **Identity Layer**: W3C DIDs with on-chain verification
4. **Consensus Layer**: Corona threshold signing
