Electronic Voting System Using Blockchain

Blockchain technology is one of the innovations brought about by the rise of the digital age that has transformed how people live and how easily jobs can be completed. Blockchain is opening up new avenues for the development and exploration of various virtual services that may be applied to our everyday activities like voting, maintaining files, etc. Today, the government uses electronic voting technologies instead of the traditional voting process to cast ballots. As technology advances, voting practices also alter. Today, we vote online, and this practice is on the rise in modern society due to its many benefits, including a reduction in administrative costs and an increase in the number of voters. Additionally, it does away with the outdated idea of polling places and voting machines. It introduces new concepts and helps voters to cast votes whenever and from wherever there is an internet connection the voters want according to their preferences. Despite their number of benefits online voting systems have a number of cautions, because they bring new threats. A single exposure can result in a large vote; therefore, online voting must be safe and legal when used in elections. The introduction of blockchain technology in online voting systems can lead to the reduction of these issues and offers decentralized nodes for electronic voting which help in end-to-end verification advantages. This technology is a stunning replacement for traditional electronic voting solutions with more privacy for the voters and security. The following paper provides an overview of electronic voting based on blockchain technology and aims to review the current literature on blockchain-based electronic voting systems and look forward to improving the future. The blockchain-based technology is secure, reliable, efficient, anonymous, and faster and helps to increase the number of voters and people's confidence in the democracy of our country but on the other hand; it faces issues related to safety traits, privacy protection, and transaction speed. For proper development of this technology, it should be secure and its transaction speed must be fast.
