Expand description

Pedersen VRF proof.

Zero-knowledge proof with key-hiding properties:

  • pk_com: Commitment to the public key (Y_b = x·G + b·B)
  • r: Nonce commitment for the generator (R = k·G + k_b·B)
  • ok: Nonce commitment for the input point (O_k = k·I)
  • s: Response scalar for the secret key
  • sb: Response scalar for the blinding factor
