Votereum: An Ethereum-Based E-Voting System

Blockchain, which is the underlying technology of the first cryptocurrency Bitcoin, has drawn a lot of global attention in recent years. Its notable characteristics of the distributed ledger, trustless system, and immutability not only makes it a disruptive innovation in the electronic payment industry but also potential solutions for other areas that require trust establishment. Electronic voting (E-voting) scheme is a use-case where all attributes of blockchain can offer a mechanism for an open, fair and universally verifiable electoral process. In this paper, we review the requirements and then propose Votereum, an E-voting system that utilizes the blockchain technology. The proposed system is empowered by Ethereum platform, including one server manages the entire system and the other handles all blockchain-related requests. The implementation is also deployed to Rinkeby testing network for evaluation on the feasibility and discussion on some security concerns, which are mentioned in the conclusion of this paper.
