Detailed Description

Constraints for addition of two points on the Grumpkin curve.

EcAdd constraints have 10 components:

  • input1_x: x-coordinate of the first input point
  • input1_y: y-coordinate of the first input point
  • input1_infinite: flag indicating if the first input point is the point at infinity
  • input2_x: x-coordinate of the second input point
  • input2_y: y-coordinate of the second input point
  • input2_infinite: flag indicating if the second input point is the point at infinity
  • predicate: flag indicating whether the constraint is active
  • result_x: witness index for the x-coordinate of the resulting point
  • result_y: witness index for the y-coordinate of the resulting point
  • result_infinite: witness index for the flag indicating if the result is the point at infinity

The data related to input1 and input2 can either be given by witnesses or constants. However, x and y coordinates pertaining to the same input must be either all witnesses or all constants.
