E-voting system using blockchain technology

Abstract

In recent years, cryptocurrencies have revolutionised the financial world with the introduction of Bitcoin. The Bitcoin operates in a decentralised network, where everyone is an owner, and no central server exists. This decentralised network is called a blockchain, and since its conception has evolved beyond its primary use. The idea of decentralised applications gave birth to new and innovative ways of designing applications. This idea continued growing with the introduction of smart contracts on another the Ethereum blockchain, giving new possibilities to developers. This dissertation provides one such application of blockchain technology, which area is blockchain based electronic voting. This application is analysed in the context of Malta and is aimed at replacing the currently used paper-based vote casting system. The system is designed under the constraint that the users have to be physically present at the polling booths The voting system is finally evaluated in terms of security and efficiency.
