Documentation

Overview

Package reuse heuristic This heuristic just checks if an address that appears in the input set, appears also in the output set, we just need to count the number of transactions in which this condition is satisfied. This happens when a user uses the same address to pay and to recollect the exceeding amount of a transaction.

Types

type AddressReuse

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

AddressReuse heuristic

func (*AddressReuse) ChangeOutput

func (h *AddressReuse) 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 (*AddressReuse) Vulnerable

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

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

type Worker

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

Worker struct implementing workers pool

func (*Worker) Work

func (w *Worker) Work() (err error)

Work executed in the workers pool
