# Masque ID

**Masque ID** is the decentralized protocol that manages on-chain identities for compliant digital assets. It integrates on-chain identity verification with off-chain document storage to satisfy KYC requirements while preserving user privacy.

**Key Features**

* **Hybrid Storage** sensitive documents (passports, PAN, Aadhaar) live with trusted KYC providers; only encrypted proofs and tamper-proof attestations appear on-chain
* **Cryptographic Validation** claims are signed by the registered claim issuer (`ZodorClaimIssuer`) and verifiable on-chain without revealing the underlying data
* **Claims-Based Access** seven claim topics (`KYC_INDIA`, `KYC_GLOBAL`, `ACCREDITED`, `JURISDICTION`, `AML_CLEAR`, `RISK_SCORE`, `ESG_VERIFIED`) gate every transfer through `ZodorComplianceModule`
* **Dynamic Risk Scoring** risk assessments update continuously based on user behavior, jurisdiction, and provider data
* **One ID, all verticals** the same Masque ID grants access to Capital, Infra, Energy, and Infinity according to which claims it carries

**Core Workflow**

1. **Creation** user submits documents to a KYC provider (Sumsub or Digitap); provider issues an encrypted proof
2. **Anchoring** `ZKKYCGate.verifyAndMark()` checks the Groth16 proof, records the nullifier, and triggers `ZodorClaimIssuer.issueClaimFromGate()`  issuing `KYC_INDIA(1)` for jurisdiction code 356 or `KYC_GLOBAL(2)` otherwise
3. **Validation** the compliance module checks Identity and Claim Registries on every transfer
4. **Maintenance** non-compliant identities and expired claims are revoked or updated; root history is preserved so previously-generated proofs continue to verify
