Four documents, the same five questions.
No throughput league table and no yield. The cells are what this library is willing to say about the text.
| Question | BBS+ Signatures and Selective Disclosure |
|---|---|
| What the text proposes | A BBS-family signature can be proved in zero knowledge so a holder reveals only some messages and produces an unlinkable presentation. |
| Who may write | Jan Camenisch, Manu Drijvers and Anja Lehmann |
| What is settled | The issuer signs a vector of messages. |
| Load-bearing assumption | The paper's scheme is not every library that says BBS. |
| What this library says afterwards | A reading of the public document. Not a copy of it, and not a claim about a later network that reused the name. |
| Rights | Official external source only |
