CHLOM Metaprotocol — Policy & Compliance Registry — Architecture, Data Model, and Enforcement Framework

This document defines the Policy & Compliance Registry (PCR) within the CHLOM Metaprotocol. The PCR is the authoritative, blockchain-anchored repository for all governance policies, compliance rules, licensing terms, and jurisdictional constraints that must be enforced across the CHLOM ecosystem. It integrates deeply with the DID layer, biometric multi-sig mechanisms, and TLAAS/DLA components to ensure tamper-proof, auditable policy enforcement.

1. Purpose & Scope

The PCR provides:

• A decentralized, immutable source of compliance and licensing rules.
• Machine-readable policy definitions for automated verification.
• Integration with governance workflows, licensing exchanges, and cross-chain execution.
• Real-time updates via policy event streams.
• Patent-protected compliance enforcement logic.

2. Architecture Overview

• Policy Registry Smart Contract: On-chain storage of hashed policy documents with metadata.
• Off-Chain Policy Store: IPFS/Arweave-based full policy content storage.
• Compliance Engine: Validates transactions and governance proposals against registered policies.
• Event Bus: Publishes policy changes to all CHLOM components.
• Access Controller: Ensures only authorized entities (via DID + fingerprint multi-sig) can modify policies.

3. Data Model (JSON Schema)

{
  "policyId": "string",
  "version": "string",
  "jurisdiction": "string",
  "hash": "sha256-hex",
  "effectiveDate": "YYYY-MM-DD",
  "expiryDate": "YYYY-MM-DD",
  "enforcementLevel": "mandatory|advisory",
  "associatedLicenses": ["licenseId1", "licenseId2"]
}

4. Solidity Policy Registry Contract Example

// SPDX-License-Identifier: BUSL-1.1
pragma solidity ^0.8.24;

contract PolicyRegistry {
    struct Policy {
        string version;
        string jurisdiction;
        string hash;
        uint256 effectiveDate;
        uint256 expiryDate;
        bool mandatory;
    }

    mapping(string => Policy) public policies;

    event PolicyRegistered(string policyId, string version, string hash);

    function registerPolicy(
        string calldata policyId,
        string calldata version,
        string calldata jurisdiction,
        string calldata hash,
        uint256 effectiveDate,
        uint256 expiryDate,
        bool mandatory
    ) external {
        // DID + biometric multi-sig check here
        policies[policyId] = Policy(version, jurisdiction, hash, effectiveDate, expiryDate, mandatory);
        emit PolicyRegistered(policyId, version, hash);
    }
}

5. Enforcement Workflow

1. Transaction/Proposal Submitted
2. Compliance Engine Queries PCR
3. Policy Hash Match & Date Validation
4. Decision: Approve / Reject / Flag for Review

6. Integration Points

• Governance Proposal Lifecycle (pre-execution validation)
• Licensing Exchange (license issuance checks)
• Cross-Chain Governance Router (execution blocking on policy breach)

7. Security & Audit

• SHA-256 hashing for immutability.
• Multi-sig authentication for policy updates.
• Event logs stored in the CHLOM Audit Layer.

8. Patent & Licensing Protections

This Policy & Compliance Registry architecture is patent-pending and includes protections for automated, blockchain-anchored compliance enforcement across multi-chain and Web2/Web3 integrated environments. Any usage requires licensing via crownthrive.com.
