Classification of Blockchain based Voting: Challenges and Solutions

Voting is a significant procedure for people to settle on their own leader for the government. The issue of preventing fraud and establishing democracy has always been a major challenge in all countries. In the Digital age, the conventional paper votes have been replaced by the benefits of low costs, high performance and little errors. The simple truth that electronic voting processes have been preserved in the central database causes issues: voting data isn’t accessible and clear enough, and they are easy to hack and to falsify, the users experience a risk of leakage and the voting outcomes can not be checked by voters. Blockchain is the infrastructure that will help us reduce the identity uncertainty and provide accountability, transparency in voting systems. Many researchers have proposed several solutions inheriting the diverse features of the Blockchain. Understanding the features and their importance in Blockchain Voting is an important topic. Therefore, this paper focuses on a systematic review by several authors of different forms of blockchain-based voting to identify challenges and solutions of blockchain for using in voting and help researchers to make a proper voting framework in the perspective of their country.
