Owner: CrownThrive, LLC Date: 2025-08-08 Classification: Internal — Decentralized Licensing Marketplace Data & Governance Framework
1. Purpose
The LEX Data Architecture & Governance Specification defines how all licensing, compliance, and transaction data is structured, stored, governed, and secured. It ensures regulatory compliance, privacy preservation, and operational efficiency while enabling scalable integration with AI/ML-driven fraud detection, ZKP verification, and DAO governance.
2. Data Sources & Schemas
- On-Chain Data: License NFTs/SFTs, transaction logs, DAO proposals, dispute resolutions.
- Off-Chain Data: Metadata (IPFS), audit logs (Arweave), compliance proofs, AI/ML model outputs.
- External Data: KYC/AML provider responses, sanctions lists, regulatory API feeds.
Schema standards:
- License Record:
- Transaction Log:
- AI/ML Result:
3. Data Lineage Map
- Issuance: Originates from issuer, validated by ZKP engine, stored on-chain.
- Transfer: Updates both on-chain registry and off-chain metadata.
- Compliance Check: Off-chain service logs proofs to Arweave and hashes to blockchain.
- Audit Trail: Immutable storage ensures traceability across all lifecycle events.
4. Retention & Archival Policies
- On-Chain Data: Permanent.
- Off-Chain Metadata: Minimum 10 years in IPFS pinning nodes.
- AI/ML Logs: Rolling 5-year retention for model retraining.
- Compliance Proofs: Permanent archival in Arweave.
5. Privacy Classifications
- Public: License ID, issuance date, status.
- Protected: Holder identity (encrypted), jurisdictional metadata.
- Restricted: KYC/AML raw data, accessible only to authorized compliance nodes.
6. ZKP Boundaries
- Proof Generation: Off-chain verifier produces zk-SNARK/zk-STARK proofs.
- Verification: On-chain smart contract validates without exposing sensitive data.
- Boundaries: No raw KYC data is stored on-chain; only proof hashes and validity flags.
7. Dataset Entitlement & Access Matrix
| Dataset | Public | DAO | Issuer | Regulator | AI/ML Service |
| License Registry | R | RW | RW | R | R |
| Compliance Proofs | R | RW | RW | RW | R |
| Fraud Scores | - | RW | R | R | RW |
R: Read, RW: Read/Write
8. API & Integration Governance
- Authentication: OAuth2 + mTLS.
- Access Control: Role-based, token-scoped permissions.
- Data Standards: JSON-LD for interoperability; IPFS CIDs for immutable references.
9. Compliance Alignment
- GDPR/CCPA: Right to erasure handled via metadata encryption key revocation.
- FINRA/SEC: Licensing transaction logs meet retention and audit standards.
- FATF: Adheres to Travel Rule for cross-border transfers.
10. Developer Build Notes
- Backend: Rust for blockchain layer, Python for AI/ML ingestion pipelines.
- Data Storage: IPFS cluster for active metadata, Arweave for permanent archives, PostgreSQL for operational data.
- Security: AES-256-GCM encryption for sensitive data, TLS 1.3 for transport.
- Monitoring: ELK stack for log aggregation, Prometheus for performance metrics.
This Data Architecture & Governance specification ensures LEX operates under strict compliance and governance principles, enabling secure, scalable, and auditable license exchanges across industries.
