Pedersen Commitment Division #281

Closed arthurgreef closed 5 years ago

arthurgreef commented 5 years ago

Hi - the following link is a protocol for sealed bid auctions. The protocol divides one pedersen commitment by another. It is not obvious to me if the pedersen commitment API supports this division operator. Am I missing something? Thanks.

Hi,

The article uses multiplicative notation when dividing B_i by B_j, division of two points can be seen as subtraction using additive notation
