func NewClassGroupFromBytesDiscriminant ¶
func NewClassGroupFromBytesDiscriminant(buf []byte, discriminant *big.Int) (*ClassGroup, bool)
func (*ClassGroup) BigPow ¶
func (group *ClassGroup) BigPow(n *big.Int) *ClassGroup
func (*ClassGroup) Discriminant ¶
func (group *ClassGroup) Discriminant() *big.Int
func (*ClassGroup) Equal ¶
func (group *ClassGroup) Equal(other *ClassGroup) bool
func (*ClassGroup) Multiply ¶
func (group *ClassGroup) Multiply(other *ClassGroup) *ClassGroup
func (*ClassGroup) Normalized ¶
func (group *ClassGroup) Normalized() *ClassGroup

func (group *ClassGroup) Pow(n int64) *ClassGroup
func (*ClassGroup) Reduced ¶
func (group *ClassGroup) Reduced() *ClassGroup
func (*ClassGroup) Serialize ¶
func (group *ClassGroup) Serialize() []byte
Serialize encodes a, b based on discriminant's size using one more byte for sign if nessesary
func (*ClassGroup) Square ¶
func (group *ClassGroup) Square() *ClassGroup
func (*ClassGroup) SquareUsingMultiply ¶
func (group *ClassGroup) SquareUsingMultiply() *ClassGroup
type VDF ¶
type VDF struct {
// contains filtered or unexported fields
}
VDF is the struct holding necessary state for a hash chain delay function.
func (*VDF) Execute ¶
func (vdf *VDF) Execute()
Execute runs the VDF until it's finished and put the result into output channel. currently on i7-6700K, it takes about 14 seconds when iteration is set to 10000
func (*VDF) GetOutput ¶
GetOutput returns the vdf output, which can be bytes of 0s is the vdf is not finished.
func (*VDF) GetOutputChannel ¶
GetOutputChannel returns the vdf output channel. VDF output consists of 258 bytes of serialized Y and 258 bytes of serialized Proof
func (*VDF) IsFinished ¶
IsFinished returns whether the vdf execution is finished or not.
