Just as a 3rd case next to RSA and CS.
Additional InformationWould be good to have sometime in Q4'2025 ;-).

The referenced paper requires interactive proofs (e.g. the signature cannot be "unblinded" as is expected in the API). It is unclear if that is actually required by the taler protocol, but the scheme is classical (interactive) ZKP

I think this could be done actually looking at the code (if it compiles) rather easily.
