Types

type VDF

type VDF struct {
	// contains filtered or unexported fields
}

VDF is the struct holding necessary state for a hash chain delay function.

func New

func New(difficulty int, input [32]byte) *VDF

New create a new instance of VDF.

func (*VDF) Execute

func (vdf *VDF) Execute()

Execute runs the VDF until it's finished and put the result into output channel.

func (*VDF) GetOutput

func (vdf *VDF) GetOutput() [32]byte

GetOutput returns the vdf output, which can be bytes of 0s is the vdf is not finished.

func (*VDF) GetOutputChannel

func (vdf *VDF) GetOutputChannel() chan [32]byte

GetOutputChannel returns the vdf output channel.

func (*VDF) IsFinished

func (vdf *VDF) IsFinished() bool

IsFinished returns whether the vdf execution is finished or not.
