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.
- Uses Soulbound Tokens (SBTs) for non-transferable credentials and reputation.
- 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.
D. SBTs (Soulbound Tokens)
- Definition: Non-transferable tokens permanently bound to a DID, representing identity attributes, credentials, or achievements.
- Role in CHLOM™:
- Store and signal reputation, licenses, and governance rights.
- Prevent credential transfer or sale, ensuring authenticity.
- Allow TLaaS and governance layers to instantly validate a participant’s standing.
3. Operational Flow
Step 1 — Enrollment
- User scans fingerprint on approved biometric device.
- Device generates a secure template → hashes it → creates a biometric commitment.
- DID is generated or linked, storing:
- Verifiable credentials issued via TLaaS and bound to the DID.
- Relevant credentials minted as SBTs, permanently linked to the DID.
Step 2 — Authentication & Compliance Check
- User attempts an action (vote, transaction, license execution).
- Provides ZKPs proving:
- Validators confirm proofs without accessing raw data.
Step 3 — Cross-Platform Operation
- DID and SBTs recognized in:
- CHLOM Layer-1.
- DLA governance.
- DAL/ADE settlement flows.
- Fingerprint binding prevents unauthorized DID transfer.
- ZKPs enable secure interoperability with other blockchains and Web2 systems.
4. Security & Privacy Advantages
- No central database of biometric images.
- Public ledger safe — only proofs and SBT metadata are shared.
- Prevents identity fraud in governance and licensing.
- GDPR/HIPAA-compliant identity verification.
- SBTs ensure credentials remain authentic and non-transferable.
5. Strategic Importance
- Compliance Moat: Institutions trust licenses tied to verified humans with immutable credentials.
- Regulatory Advantage: Aligns with legal identity requirements.
- Governance Integrity: Strengthens DLA operations.
- Reputation Moat: SBTs create a permanent, verifiable track record.
- Interoperability: Extends identity and credential standards across multiple chains.
