Document Version: 1.0 Date: August 8, 2025 Author: CrownThrive, LLC — [email protected] Project: CHLOM™ — Compliance Hybrid Licensing & Ownership Model
1. Objective
Provide an extremely high-level API reference for developers building integrations with the Decentralized Licensing Authority (DLA) smart contracts under the TLAAS protocol. This guide defines all callable functions, input/output structures, event formats, and security considerations.
2. API Design Principles
- Modularity — Functions should be composable and reusable.
- Security — All functions protected by role-based access control (RBAC).
- Gas Efficiency — Optimize for minimal cost without sacrificing security.
- Interoperability — Designed to integrate seamlessly with DAL, LEX, Compliance AI, and CHLOM Ledger.
3. Core API Endpoints (On-Chain Functions)
License Management
- issueLicense(address _owner, string memory _metadataHash)
- Purpose: Create a new license linked to a DID and Fingerprint ID.
- Returns:
- renewLicense(string memory _licenseId)
- Purpose: Extend license validity period.
- transferLicense(string memory _licenseId, address _newOwner)
- Purpose: Transfer ownership after compliance verification.
Compliance Enforcement
- enforceCompliance(string memory _licenseId)
- Purpose: Trigger compliance checks and enforcement.
- suspendLicense(string memory _licenseId)
- Purpose: Temporarily halt license privileges.
- revokeLicense(string memory _licenseId)
- Purpose: Permanently remove license rights.
Governance Hooks
- proposeEnforcement(string memory _licenseId, string memory _action)
- Purpose: Create a DAO proposal for enforcement action.
- executeEnforcement(uint _proposalId)
- Purpose: Carry out DAO-approved enforcement.
Identity Binding
- bindIdentity(string memory _licenseId, bytes32 _fingerprintHash, string memory _ownerDID)
- Purpose: Associate a license with biometric and DID identifiers.
4. Events
- LicenseIssued(string licenseId, address owner, uint timestamp)
- LicenseTransferred(string licenseId, address from, address to, uint timestamp)
- ComplianceViolation(string licenseId, uint timestamp, string reason)
- GovernanceProposalCreated(uint proposalId, string licenseId, string action)
- GovernanceActionExecuted(uint proposalId, string action, uint timestamp)
5. Example Contract Snippet
function issueLicense(address _owner, string memory _metadataHash) public onlyLicensingOfficer returns (string memory) {
string memory licenseId = generateLicenseId(_owner, _metadataHash);
licenses[licenseId] = LicenseData({owner: _owner, metadataHash: _metadataHash, status: "Active"});
emit LicenseIssued(licenseId, _owner, block.timestamp);
return licenseId;
}
6. Security Considerations for Developers
- All mutating functions require RBAC role checks.
- Input sanitization for all strings to prevent injection attacks.
- Immutable event logging for all state changes.
- DAO multi-sig approval for irreversible actions.
7. Phase Roadmap for Development
- Phase 0 — Define API functions, events, and security constraints.
- Phase 1 — Implement and unit test all functions.
- Phase 2 — Integrate API with Compliance AI and DAL.
- Phase 3 — Conduct full penetration testing.
- Phase 4 — Deploy to mainnet with DAO oversight.
- Phase 5 — Expand API for multi-chain compatibility.
Next Developer Task: Proceed to Automation Runbooks for DLA (Phase 0) — define recurring jobs, enforcement triggers, and operational procedures for maintaining compliance and license integrity.
