1. Purpose

To provide a privacy-preserving, cryptographically secure identity layer for the CrownThrive™ ecosystem that:

• Uniquely identifies users, validators, and licensed entities.
• Allows compliance verification without revealing raw personal data.
• Embeds biometric fingerprint matching into a decentralized identity lifecycle.
• Enables cross-chain license portability and verification.

2. Core Components

A. DID (Decentralized Identifiers)

• Definition: Globally unique IDs anchored on a blockchain or distributed ledger, not tied to any central authority.
• Role in CHLOM™:
• Serves as the primary identity anchor across all CrownThrive platforms.
• Links to verifiable credentials (licenses, certifications, permissions) stored off-chain but cryptographically referenced.
• Portable between CHLOM sub-networks and compliant external blockchains.

B. Fingerprint ID

• Definition: Biometric match data derived from a fingerprint scan, processed into a non-reconstructable template.
• Role in CHLOM™:
• Binds a DID to its rightful human or authorized device.
• Stores only hashed biometric templates as cryptographic commitments.
• Enforces one-human-one-vote and prevents Sybil attacks.

C. ZKP (Zero-Knowledge Proofs)

• Definition: Cryptographic proofs allowing verification without revealing underlying data.
• Role in CHLOM™:
• Proves biometric match without exposing the fingerprint template.
• Allows DID holders to prove license validity without revealing personal details.
• Enables compliance checks at consensus without leaking private data.

3. Operational Flow

Step 1 — Enrollment

1. User scans fingerprint on approved biometric device.
2. Device generates a secure template → hashes it → creates a biometric commitment.
3. DID is generated or linked, storing:
4. Verifiable credentials (e.g., KYC, license) issued via TLaaS and bound to the DID.

Step 2 — Authentication & Compliance Check

1. User attempts an action (vote, transaction, license execution).
2. Provides ZKPs proving:
3. Validators confirm proofs without accessing raw data.

Step 3 — Cross-Platform Operation

• DID recognized in:
• CHLOM Layer-1.
• DLA governance.
• DAL/ADE settlement flows.
• Fingerprint binding prevents unauthorized DID transfer.
• ZKPs enable interoperability with other blockchains and Web2 systems.

4. Security & Privacy Advantages

• No central database of biometric images.
• Public ledger safe — only proofs are shared.
• Prevents identity fraud in governance and licensing.
• GDPR/HIPAA-compliant identity verification.

5. Strategic Importance

• Compliance Moat: Institutions trust licenses tied to verified humans.
• Regulatory Advantage: Aligns with legal identity requirements.
• Governance Integrity: Strengthens DLA operations.
• Interoperability: Extends identity standards across multiple chains.
