Functions

func PairingCheck

func PairingCheck(a []*G1, b []*G2) bool

PairingCheck calculates the Optimal Ate pairing for a set of points.

Types

type G1

type G1 struct {
	bn256.G1
}

G1 is an abstract cyclic group. The zero value is suitable for use as the output of an operation, but cannot be used as an input.

func (*G1) Add

func (e *G1) Add(a, b *G1) *G1

Add sets e to a+b and then returns e.

func (*G1) ScalarMult

func (e *G1) ScalarMult(a *G1, k *big.Int) *G1

ScalarMult sets e to a*k and then returns e.

type G2

type G2 struct {
	bn256.G2
}

G2 is an abstract cyclic group. The zero value is suitable for use as the output of an operation, but cannot be used as an input.
