Main Event:

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+.
