Zero-knowledge proof (ZKP) functions based on DLP construction.
Functions
prove_equality_relationship_proof | Proves two commitments satisfying an equality relationship, i.e. the values embedded in c1_point and c2_point satisfying c1_value = c2_value, where c1_point = c1_value * basepoint1, c2_point = c2_value * basepoint2. It returns a proof for the above equality relationship. |
prove_product_relationship | Proves three commitments satisfying a product relationship, i.e. the values embedded in them satisfying c1_value * c2_value = c3_value. c3_value is not in the argument list, and will be directly computed from c1_value * c2_value. c?_blinding are random blinding values used in the commitments. The commitments (c?_valuevalue_basepoint+c?_blindingblinding_basepoint) are not in the argument list, as they are not directly used by the proof generation. It returns a proof for the above product relationship. |
prove_sum_relationship | Proves three commitments satisfying a sum relationship, i.e. the values embedded in them satisfying c1_value + c2_value = c3_value. c3_value is not in the argument list, and will be directly computed from c1_value + c2_value. c?_blinding are random blinding values used in the commitments. The commitments (c?_valuevalue_basepoint+c?_blindingblinding_basepoint) are not in the argument list, as they are not directly used by the proof generation. It returns a proof for the above sum relationship. |
verify_equality_relationship_proof | Verifies two commitments satisfying an equality relationship, i.e. the values embedded in c1_point, c2_point satisfying c1_value = c2_value, where c1_point = c1_value * basepoint1, c2_point = c2_value * basepoint2. |
verify_equality_relationship_proof_in_batch | Verifies all commitment pairs satisfying equality relationships, where each commitment pair contains two commitment points, c1_point = c1_point_list[i], c2_point = c2_point_list[i], and the values embedded in c1_point, c2_point satisfying c1_value = c2_value. |
verify_product_relationship | Verifies three commitments satisfying a product relationship, i.e. the values embedded in c1_point, c2_point, c3_point satisfying c1_value * c2_value = c3_value. |
verify_product_relationship_in_batch | Verifies all commitment tuples satisfying product relationships, where each commitment tuple contains three commitment points, c1_point = c1_point_list[i], c2_point = c2_point_list[i], c3_point = c3_point_list[i], and the values embedded in c1_point, c2_point, c3_point satisfying c1_value * c2_value = c3_value. |
verify_sum_relationship | Verifies three commitments satisfying a sum relationship, i.e. the values embedded in c1_point, c2_point, c3_point satisfying c1_value + c2_value = c3_value. |
verify_sum_relationship_in_batch | Verifies all commitment tuples satisfying sum relationships, where each commitment tuple contains three commitment points, c1_point = c1_point_list[i], c2_point = c2_point_list[i], c3_point = c3_point_list[i], and the values embedded in c1_point, c2_point, c3_point satisfying c1_value + c2_value = c3_value. |
