Parameters:

• #x (Num): the position on the x-axis.
• #y (Num): the position on the y-axis.

Provides a public point in the two-dimensional space on the given Secp256k1 elliptic curve by passing a random number (private key). Note, that the private key will be consumed by this constructor and should only be used to retrieve a public key. To manage keypairs, use the Key type instead.

Parameters:

• priv (Num): the random number giving access to the point.
