Part 3 — Building Blocks

Part 3 takes each component of the OID4VC stack and explains it in a self-contained chapter. You can read these in order or jump to the one you need.

Each chapter answers: what problem does this piece solve, how does it work, and what does it look like in practice?

  • Chapter 7 — did:web: how issuers publish their public keys without a blockchain
  • Chapter 8 — SD-JWT: how credentials support selective disclosure
  • Chapter 9 — OID4VCI: how a wallet receives a signed credential from an issuer
  • Chapter 10 — OID4VP: how a wallet presents a credential to a verifier

Coming soon.
