We consider the problem of creating, or issuing, zero-knowledge proofs obliviously. In this setting, a prover interacts with a verifier to produce a proof, known only to the verifier. The resulting proof is transferable and can be verified non-interactively by anyone. Crucially, the actual proof cannot be linked back to the interaction that produced it.


This notion generalizes common approaches to designing blind signatures, which can …
