Types

type Forward

type Forward struct {
	Kv    kv.DB
	Cache *cache.Cache
}

Forward heuristic

func (*Forward) ChangeOutput

func (h *Forward) ChangeOutput(transaction *tx.Tx) (c []uint32, err error)

ChangeOutput returns the index of the output which appears both in inputs and in outputs based on address reuse heuristic

func (*Forward) Vulnerable

func (h *Forward) Vulnerable(transaction *tx.Tx) bool

Vulnerable returns true if the transaction has a privacy vulnerability due to optimal change heuristic
