Blockchain Based Electronic Voting System

In today’s digital environment, the voting system has moved from paper based to a digital system. A digital e-voting system has many properties such as transparency, decentralization, irreversibility, and non-repudiation. The growth in the digital e-voting system raises many security and transparency issues. In this paper, we used the blockchain technology in the digital electronic voting system to solve the security issues and ful?ll the system requirements. It offers new opportunities to deploy a secure e-voting system in any organization or country. The solution is far better as compared to other solutions because it is a decentralized system, containing the results in the form of bit-coins, having different locations. We will also analyze the security of our proposed voting system, which shows our protocol is more secure as compared to other solutions. The paper proposes a novel electronic voting system based on block chain that addresses some of the limitations in existing systems and evaluates some of the popular blockchain frameworks for the purpose of constructing a blockchain based e-voting system. In particular, we evaluate the potential of distributed ledger technologies through the description of a case study namely, the process of an election, and the implementation of a blockchain based application, which improves the security and decreases the cost of hosting a nation wide election.
