Main Identity WG
- Meeting Notes: 2021-02-17
  - Kaliya "Identity Woman" Young presents her new paper on VC Flavors.
    - The first part of the paper elaborates on the following three data formats of VCs by walking through a credential lifecycle:
      - JSON-LD family with LD Signatures or with BBS+ Signatures that enable Zero Knowledge Proofs (ZKP or ZKPs)
      - JSON with JSON Web Signatures, precisely in the form of a JSON Web Token (JWT)
      - ZKP with Camenisch-Lysyanskaya Signatures (ZKP-CL)
    - The second part discusses at length the differences between JSON and JSON-LD and the differences between the two different ways to express ZKPs, namely ZKP-CL and the newest flavor JSON-LD ZKP with BBS+.
