Introduction to Verifiable Credentials
summary
Overview of Verifiable Credentials with a hands‑on Quarkus demo that issues, stores and verifies credentials using Keycloak for OpenID Connect, an issuer (Software Credentials Academy), a wallet emulator and a verifier service. Demonstrates both issuer‑initiated and verifier‑initiated flows, shows SD‑JWT selective disclosures where the wallet reveals only title and name, and verifies presentations successfully. Covers key binding, zero‑knowledge proofs and BBS signatures, notes post‑quantum risks and that the demo flow works end‑to‑end.
