A decentralized and trustless e-voting system based on blockchain technology

Abstract

Voting is essential for any modern society. E-voting has been grabbed remarkable attention in recent years as it reduces the cost of the process and increases transparency. Blockchain technology opened the door to a new approach to evoting. Some studies were conducted to design e-voting schemes utilizing blockchain as a public bulletin board, providing the ability for verifiability and self-tallying. In this paper, we propose a novel trustless e-voting scheme based on blockchain technology that minimizes the intervention of authorities in the process, and voters can vote remotely using their own mobile devices. This scheme prevents voters from selling their votes, and anyone can cast his/her vote for free. In addition, everyone in the network can tally the final result and verify the correctness of the votes.
