NAPADI VEZANI ZA REDOSLED I TEMPIRANJE NA L2 BLOCKCHAIN MREŽAMA
Ključne reči:
blokčejn, problem skalabilnost, bezbednost
Apstrakt
U ovom radu će biti predstavljene L2 blockchain mreže, napadi vezani za redosled transakcija, redosled instrukcija u transakciji, te napadi vezani za tempiranje na pomenutim mrežama. Rad uključuje i implementaciju jednostavnog pametnog ugovora za bolji prikaz efekata nekih od navedenih napada. Na kraju, dati su načini odbrambenih mehanizama za potpunu zaštitu ili smanjivanje efektivnosti napada.
