Types

type Cuckoo

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

Cuckoo is struct for cuckoo miner.

func NewCuckoo

func NewCuckoo() *Cuckoo

NewCuckoo returns Cuckoo struct to do PoW.

func (*Cuckoo) PoW

func (c *Cuckoo) PoW(siphashKey []byte) ([]uint32, bool)

PoW does PoW with hash, which is the key for siphash.
