Overview

Package backward heuristic It checks the transactions that come before the one in which we want to find the change address.

Types

type Backward

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

Backward heuristic

func (*Backward) ChangeOutput

func (h *Backward) 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 (*Backward) Vulnerable

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

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