A design for blockchain-based digital voting system
(Springer, 2019) Al-Rawy, Mahmood; Elçi, Atilla
In recent years, blockchain technology has affected to a large extent all aspects of life, however, until now paper-based elections have been practiced. It is time to upgrade the election scenario using modern technology such as blockchain and advanced cryptography methods. Actually, both of Estonia and New South Wales have been using i-voting systems, but after developing an example software of their systems for the purpose of analysis, it is discovered that it has weaknesses against many kinds of attacks, such as malwares, network attacks, and servers attacks. The fact that the blockchain technology has demonstrated infinite immutability and resistance against hacking, so it is possible to use it to secure election results from fraud by saving every single piece of data, record or transaction with unchangeable history. By abandoning the traditional database and compensating it with two blockchains instead of one ensures voter/vote privacy, as well as, safeguards the results from manipulation. Also, using blockchain’s distributed network reduces the load on the network. Finally, solutions to problems of impersonation and vote selling are suggested. The technology behind the digital voting system design is explained in terms of the processes involved, such as ID creation, authentication, voting, and vote tallying. © Springer Nature Switzerland AG 2019.
