Survey on blockchain-based electronic voting

Abstract

With the progress of society and the improvement of people’s democratic consciousness, voting, as a channel to fully develop democracy, is playing an increasingly important part in many application scenarios. In the era of Internet, electronic voting has replaced the traditional paper voting with the advantages of low cost, high efficiency and few mistakes. The fact that the data of electronic voting system is stored in the central database gives rise to the following problems: the voting data is not open and transparent enough, and it is easy to be tampered with and forged; the users’ private information faces the risk of being leaked; voters can not verify the voting results. Fortunately blockchain technology can make up for the shortcomings of the current voting system, making the voting process open and transparent, preventing fraudulent votes, enhancing the security of voting data and verifying the voting results. The application of blockchain electronic voting system has very important significance and prospects. In this paper, we first introduce the development process of electronic voting system at home and abroad, then introduce the development status of blockchain-based electronic voting system, finally we compare and summarize several typical blockchain-based electronic voting schemes.
