CHLOM License Exchange (LEX) — End-to-End Technical & Development Master Plan (Phase 3→4)

Owner: CrownThrive, LLC Date: 2025-08-08 Classification: Internal — Decentralized Licensing Marketplace Full Build Guide

1. Purpose & Scope

The CHLOM License Exchange (LEX) is a decentralized, compliance-driven marketplace for issuing, buying, selling, sublicensing, and transferring digital licenses as NFTs/SFTs. This master plan outlines all technical, governance, and operational layers required from concept to production, ensuring maximum detail so development teams can execute without ambiguity.

Key Objectives:

  • Deliver a fully functioning marketplace with DAO governance hooks.
  • Ensure ZKP-based compliance checks for every license transaction.
  • Enable on-chain and cross-chain interoperability.
  • Serve as a revenue and governance participation engine for CHLOM DAO.

2. Recommended Phase Placement

LEX should be initiated in Phase 3 for base infrastructure and MVP, with full DAO integration, smart treasury connectivity, and tokenomics alignment in Phase 4.

3. Architecture Overview

Core On-Chain Components:

  • NFT/SFT License Contracts: ERC-721/ERC-1155 style but optimized for compliance metadata.
  • Atomic Escrow Engine: Locks assets until ZKP verification passes.
  • ZKP Verifier Contracts: Integrated with CHLOM ZK circuits.
  • On-Chain License Registry: Immutable ownership and metadata history.

Core Off-Chain Components:

  • API Gateway: REST + gRPC for marketplace operations.
  • Search & Discovery Engine: Indexed license metadata with advanced filters.
  • Fraud Detection AI: Runs graph-based anomaly detection on listings and transactions.
  • Admin Console: DAO-controlled policy updates, fee changes, and dispute resolution.

High-Level Transaction Flow:

  1. License issuer lists NFT/SFT with metadata and compliance references.
  2. Buyer selects license and commits funds.
  3. ZKP compliance check is executed.
  4. If passed, escrow releases NFT/SFT to buyer.
  5. Registry updates with transaction hash and new owner.

4. Data Architecture

  • License Metadata Fields: issuer_id, license_scope, jurisdiction, expiry_date, zk_refs, compliance_status, dispute_status.
  • Transaction Audit Log: Immutable, signed JSON events stored on IPFS/Arweave.
  • Search Index Fields: License category, jurisdiction, compliance rating, industry sector.

5. API & Integration Points

  • Public API: Browse/search licenses, verify proof, view metadata.
  • Partner API: Direct minting and listing for corporate issuers.
  • Governance API: Adjust DAO parameters such as fee rates and listing rules.
  • CaaS & TLaaS Hooks: Automated scoring and license validation.

6. Security & Trust Boundaries

  • Authentication: mTLS + OAuth2 for APIs.
  • Zero-Knowledge Proofs: Compliance validation without revealing sensitive data.
  • RBAC & Multi-Sig: For admin and DAO treasury actions.
  • Pen-Testing & Audits: Every major release undergoes 3rd-party review.

7. Marketplace Economics & Tokenomics

  • Fee Models: Flat % of sale, listing fee tiers, DAO-set discounts.
  • Staking Incentives: CHLOM token staking for boosted listings.
  • Penalty Escrow: Fraud results in stake slashing.
  • Revenue Routing: Automated distribution to smart treasury, liquidity pools, and community funds.

8. Full Development Roadmap

Phase 3 (MVP Build):

  • Smart contract core build.
  • Metadata schema & registry deployment.
  • ZKP verifier integration.
  • API gateway MVP.
  • Search index prototype.

Phase 4 (Full Integration):

  • DAO-controlled marketplace parameters.
  • Smart treasury integration.
  • Advanced tokenomics and staking.
  • Dispute resolution via on-chain arbitration.

Phase 5 (Global Expansion):

  • Cross-chain licensing bridges.
  • Secondary market analytics.
  • License fractionalization.

9. Build Guidelines for Developers

  • Languages: Rust (chain logic), Solidity (EVM bridges), TypeScript/Node.js (API), Python (fraud AI).
  • Frameworks: Substrate, gRPC, OpenAPI.
  • Testing: Unit, property-based, integration, fuzzing, adversarial ML.
  • Deployment: Canary + rollback systems.

10. Future Extensions

  • Cross-Industry Licensing Models: Media rights, software, patents.
  • Global Regulatory Compliance Modules: Regional rulesets.
  • Automated License Valuation Engine: AI-powered pricing.

Summary: LEX is the backbone of CHLOM’s licensing economy, engineered for compliance, scalability, and interoperability, delivering a robust and DAO-governed marketplace from day one.
