Introduction to Verifiable Credentials
summary
Covers verifiable credential basics and concrete formats: SD‑JWT for selective disclosures, embedded proofs, and BBS+ suites enabling unlinkable proofs; uses DIDs, W3C VC data model, OAuth2/OIDC flows (wallet‑initiated and issuer‑initiated) and key‑binding with JWKS. Demo issues an academy credential into a wallet, uses transaction codes and selective disclosure to a verifier; presentations are verifiable though occasional transaction timeouts appear. Predicts mainstream replacement of bearer tokens in about 5–10 years.
