Decentralized verifiable credentials architecture combining Hyperledger Fabric, IPFS, and zero-knowledge proofs for privacy-preserving degree verification. Issuers submit degree data anchored as DIDs and encrypted payloads on IPFS, while holders generate zk-SNARKs locally in under 4 seconds for off-chain verification. Verifiers query revocation status against the Fabric StateDB without exposing credential details, enabling employers to validate academic credentials with minimal trust assumptions. Fork this diagram to customize credential schemas, adjust proof generation parameters, or integrate additional blockchain networks for multi-issuer scenarios.
