🎯Representing a point
Point-compression: To reduce the storage size for a curve point, one can also store a sign and thex
coordinate. It is then possible to reconstruct the y
by calculating sign * sqrt(x^3+a*x+b).

We call a Point
an element of the elliptic curve group, which we can represent with its coordinates. Let's define a Point
class to encapsulate the and coordinates in the generalised curve equation of .
