# ZK-CBDC Validation Framework
|
|||
|
|
|
|||
|
|
## Overview
|
|||
|
|
|
|||
|
|
Zero-Knowledge CBDC Validation ensures privacy-preserving compliance by enabling:
|
|||
|
|
- Balance verification without revealing balances
|
|||
|
|
- Transaction compliance without revealing transaction history
|
|||
|
|
- ZK-enabled AML and sanctions screening
|
|||
|
|
|
|||
|
|
## ZK Validation Modes
|
|||
|
|
|
|||
|
|
### Mode 1 – ZK-Balance Proofs (zkBP)
|
|||
|
|
|
|||
|
|
Proves wallet has sufficient funds **without revealing amount**.
|
|||
|
|
|
|||
|
|
**Service**: `zk-balance-proof.service.ts`
|
|||
|
|
|
|||
|
|
**API Endpoint**: `POST /api/v1/zk-cbdc/balance-proof`
|
|||
|
|
|
|||
|
|
### Mode 2 – ZK-Compliance Proofs (zkCP)
|
|||
|
|
|
|||
|
|
Ensures:
|
|||
|
|
- AML rules satisfied
|
|||
|
|
- Sanctions clear
|
|||
|
|
- Transaction within policy limits
|
|||
|
|
|
|||
|
|
**Service**: `zk-compliance-proof.service.ts`
|
|||
|
|
|
|||
|
|
**API Endpoint**: `POST /api/v1/zk-cbdc/compliance-proof`
|
|||
|
|
|
|||
|
|
### Mode 3 – ZK-Identity Proofs (zkIP)
|
|||
|
|
|
|||
|
|
Provides confirmation that:
|
|||
|
|
- A wallet belongs to a verified entity
|
|||
|
|
- Without disclosing identity attributes
|
|||
|
|
|
|||
|
|
**Service**: `zk-identity-proof.service.ts`
|
|||
|
|
|
|||
|
|
**API Endpoint**: `POST /api/v1/zk-cbdc/identity-proof`
|
|||
|
|
|
|||
|
|
## Smart Contract Verification
|
|||
|
|
|
|||
|
|
Smart contracts validate:
|
|||
|
|
```
|
|||
|
|
if zkBP && zkCP && zkIP:
|
|||
|
|
execute_CBDC_transfer()
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**Service**: `zk-verification.service.ts`
|
|||
|
|
|
|||
|
|
**API Endpoint**: `POST /api/v1/zk-cbdc/verify`
|
|||
|
|
|
|||
|
|
## Database Models
|
|||
|
|
|
|||
|
|
- `ZkProof` - ZK proof records
|
|||
|
|
- `ZkVerification` - Verification results
|
|||
|
|
|
|||
|
|
## Integration Points
|
|||
|
|
|
|||
|
|
- CBDC transaction service (existing)
|
|||
|
|
- GBIG identity graph (Volume V)
|
|||
|
|
- AML engine (existing)
|
|||
|
|
|
|||
|
|
## Note
|
|||
|
|
|
|||
|
|
ZK proof library integration required (e.g., circom, snarkjs, or similar). Current implementation uses placeholder proofs for structure.
