What is UNTP?
The United Nations Transparency Protocol (UNTP) is a standard developed for secure and verifiable sharing of digital product information in international trade. This protocol enables seamless data exchange between different countries and systems.
Verifiable Credentials
The Verifiable Credentials standard developed by W3C ensures digital identity information has:
- Cryptographic security: Protection with digital signatures
- Immutability: Guaranteed data integrity
- Instant verification: Control without need for central authority
- Interoperability: Compatibility with different systems
DID:web Protocol
DigiPilPass uses the DID:web (Decentralized Identifier) protocol to:
- Provide decentralized identity verification
- Offer security without requiring blockchain
- Work with standard web infrastructure
- Support easy key management and rotation
JWT-VC Format
JSON Web Token Verifiable Credential format offers these advantages:
- Compact and URL-safe structure
- Easy sharing via QR code
- ECDSA P-256 digital signature support
- Compatibility with common JWT libraries
- 2-year validity period
Status List Mechanism
DigiPilPass uses the Bitstring Status List standard to check credential revocation status:
- Privacy-preserving revocation checks
- Scalable bitstring compression
- Real-time status updates
- Minimal bandwidth usage
Battery Passport Verification Process
Battery passport verification steps with DigiPilPass:
- Access the passport by scanning QR code or direct link
- Download the JWT token
- Resolve did:web:digipilpass.com to get the public key
- Verify digital signature with ES256 algorithm
- Result is displayed instantly
Programmatic Verification
Independent verification for developers:
- Verification with did-jwt-vc library
- DIF (Decentralized Identity Foundation) standard library
- Node.js and browser support
- Verification without central system dependency
DigiPilPass and UNTP Compliance
DigiPilPass platform creates battery passports fully compliant with the UNTP standard. This enables data sharing in internationally accepted format, independent verification, and global supply chain integration.
