Overview

Package optimal change heuristic It tries to locate in the output set of a transaction an address that receives an amount which is smaller or equal than all inputs values. We count the transactions in which this condition is satisfied.

Types

type Optimal

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

Optimal heuristic

func (*Optimal) ChangeOutput

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

ChangeOutput returns the index of the output which value is less than any inputs value, if there is any

func (*Optimal) Vulnerable

func (h *Optimal) 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
