non_blind_sign performs a non-blind signature, which can be verified with the same method than a blind-signature.
Blind signatures over elliptic curve implementation (native & r1cs constraints) using arkworks.
Blind signature over elliptic curves, based on "New Blind Signature Schemes Based on the (Elliptic Curve) Discrete Logarithm Problem" paper by Hamid Mala & Nafiseh Nezhadansari.
Warning: experimental code, do not use in production.
Target: Groth16 over Bn254 (for Ethereum), ed-on-bn254 (BabyJubJub) for the signatures.
