Abstract

Primjena blockchain tehnologija u elektroničkom glasovanju je rad čiji je glavni cilj bio čitatelju pružiti uvid u koncept blockchaina, što je točno taj izraz, koje su potencijalne prednosti i nedostatci ovih tehnologija te budućeg potencijala ove grane IT industrije. Obrađeni su pojmovi kao što su kriptovalute, proof-of-work, proof-of-stake, pametni ugovori, algoritmi poput SHA-256 te ECDSA. Osim toga, pokazane su primjene blockchain tehnologija u kontekstu velikih korporacija, ali i na razini individualnog korisnika interneta. Osim primjena, obrađeni su i rizici korištenja ovakvih tehnologija te podložnost prevarama i ilegalnim radnjama. Praktični dio rada je obradio programski jezik za pametne ugovore kao što je Solidity te knjižnice, pakete poput HardHata i MetaMask ekstenzije za web preglednik. Ostvarena je aplikacija za elektronsko glasanje u kojoj se može putem blockchain mreže verificirati vjerodostojnost jednostavnih izbora u kojima korisnik bira jednu od nekoliko ponuđenih opcija.

Abstract (english)

The application of blockchain technologies in electronic voting is a masters thesis whose main goal was to provide the reader with an insight into the concept of blockchain, meaning of that term, what are the potential advantages and disadvantages of these technologies and the future potential of this branch of IT industry. Terms such as cryptocurrencies, proof-of-work, proof-of-stake, smart contracts, algorithms such as SHA-256 and ECDSA, are covered. In addition, the applications of blockchain technologies is described in the context of large corporations, but also at the level of individual Internet users, are shown. In addition to implementation of blockchain, the risks of using such technologies and susceptibility to fraud and illegal activities are also addressed. The practical part of the paper dealt with a programming language for smart contracts called Solidity, libraries and packages such as HardHat and MetaMask extensions for the web browser. An electronic voting application has been created in which the authenticity of simple choices in which the user chooses one of several offered options can be verified via a blockchain network.
