Study on E-Voting Systems: A Blockchain Based Approach

The traditional voting system has many flaws such as election manipulation, security breaches, transparency and privacy issues. These issues occur as the votes can be changed by a central authority in favor of one party when they are being counted manually or there can be human error while counting votes. This system puts a lot of trust in the central authority. Also, there is an economical issue due to the cost of security, human and ballot resources. Many of these issues are solved using the E-Voting system which has been successful in countries like Estonia that have implemented this system of voting. There is still an issue of universal verifiability of votes even in the Estonian E-Voting system. This paper conducts a study of various e-voting systems. From among the various existing methods, an effective blockchain based solution to solve the existing issues of E-voting has been explained. The blockchain is a database, distributed among all users on the network which will help in the verification of all votes cast without the need to put complete trust on a third-party system.
