Terminology and Concepts

Self-Sovereign Identity (SSI): A user-centric approach to digital identity, allowing individuals and organizations to control their identifiers and credentials without centralized authorities.

Decentralized Identifier (DID): A globally unique identifier resolvable via the EMPE Blockchain. A DID Document includes public keys and endpoints for trust and verification.

Verifiable Credentials (VCs): A cryptographically signed credential that attests to certain attributes of an entity. VCs follow W3C standards, ensuring integrity and authenticity.

Credential Schema: A JSON-based template defining the structure, properties, and required fields of a credential type. Ensures consistency and interoperability.

EMPE Blockchain: The ledger where DIDs are anchored, providing a trust layer that wallets and verifiers rely on for DID resolution and verification.

One-Click Deployment Portal: A provisioning tool that automates deployment, DID registration, and initial configuration of the Issuer Service.

Targeted Offering vs. Open Offering:

• Targeted Offering: Restricted to a specific recipient DID.

• Open Offering: Accessible to any wallet scanning the offering’s QR code or link.

Authorization Code Flow (Wallet Flow): A process where the wallet authenticates and proves DID ownership, exchanging authorization codes for access tokens and, ultimately, retrieving the credential.

These concepts form the foundation for understanding the Issuer Service’s APIs, credential flows, and integration with other ecosystem components.
