Owner: CrownThrive, LLC Date: 2025-08-08 Classification: Internal — Decentralized Licensing Marketplace Design & Build Guide
1. Purpose & Scope
The CHLOM License Exchange (LEX) is a decentralized marketplace for buying, selling, sublicensing, and transferring digital licenses, built on the CHLOM compliance and governance infrastructure. This document provides high-level design, development, and operational guidelines to take LEX from concept through deployment.
Goals:
- Enable secure, verifiable, and transferable digital licenses as NFTs/SFTs.
- Integrate with CHLOM’s TLaaS, CaaS, and ZKP verification layers.
- Provide a transparent, compliance-first environment for license transactions.
- Operate as a core revenue and governance participation driver for the DAO.
2. Recommended Phase Start
LEX should start in Phase 3 (core marketplace development) to be ready for Phase 4 integration with DAO governance, smart treasury, and tokenomics.
3. Architecture Overview
Core Components:
- Smart Contracts: NFT/SFT license token schema, escrow, and transfer logic.
- ZKP Verifier: Validates compliance conditions before transactions execute.
- On-Chain Registry: Immutable license records with metadata and history.
- Off-Chain Services: API gateway, search index, fraud detection AI.
- Governance Hooks: DAO-controlled parameters for fees, dispute resolution, and listing rules.
High-Level Flow:
- Seller mints or lists an existing license token.
- Buyer initiates purchase or sublicense request.
- ZKP compliance checks run.
- Funds and token transfer through atomic escrow.
- On-chain registry updates license ownership.
4. Data Architecture
- License Metadata Schema:
- issuer_id, license_scope, jurisdiction, expiry_date, zk_refs, compliance_status.
- Search & Discovery Index:
- Indexed by license type, jurisdiction, industry sector.
- Transaction Logs:
- Immutable audit trails for all license events.
5. API & Integration Points
- Public API: License search, verification requests, and metadata queries.
- Partner API: Direct integration for corporate license issuers.
- DAO Governance API: Update fee rates, listing categories, dispute procedures.
- CaaS & TLaaS Integration: Automatic compliance scoring and validation.
6. Security & Trust Boundaries
- mTLS + OAuth2 for API access.
- ZKP proofs for compliance verification without exposing sensitive data.
- Circuit & Contract Audits before each major release.
- Role-Based Access Control (RBAC) for administrative functions.
7. Marketplace Economics
- Fee Structure: % of sale + listing fees, adjustable via DAO vote.
- Staking Mechanism: Sellers stake CHLOM tokens for priority listings.
- Penalty Mechanisms: Fraudulent listings result in stake slashing.
8. Development Plan
Phase 3:
- Smart contract development.
- Core ZKP circuit implementation.
- License metadata schema finalization.
- API gateway MVP.
Phase 4:
- DAO integration for governance.
- Tokenomics linkage (CHM/CHLOM utility).
- Smart treasury revenue routing.
- Full marketplace launch.
9. Build Guidelines for Developers
- Language Stack: Rust (smart contracts), TypeScript/Node.js (APIs), Python (AI/fraud detection), Solidity (bridges if EVM-compatible).
- Frameworks: Substrate for chain logic, gRPC for service communication.
- Testing: Unit, integration, property-based, and adversarial.
- Deployment: Canary releases with rollback hooks.
10. Future Extensions
- Cross-Chain Licensing: Bridge support for licenses on multiple blockchains.
- Secondary Market Analytics: AI insights for license valuation.
- NFT Fractionalization: Shared ownership models.
Summary: LEX is the commercial engine of CHLOM’s decentralized licensing ecosystem, designed to integrate seamlessly with DAO governance, AI-driven compliance, and advanced tokenomics, ensuring scalability, security, and global adoption.
