Scalar

class blsct.Scalar(value: Any = None)

Represents an element of the finite field \(\mathbb{F}_r\), where \(r\) is the order of the generator point of the BLS12-381 G1 group.

A wrapper of MclScalar in navio-core.

Instantiating a Scalar without a parameter is equivalent to calling Scalar.random().
