A Proposal of Blockchain-Based Electronic Voting System

Abstract

The Estonian electronic voting system which is a leading electronic voting system still suffers from universal verifiability issues and may need improvement of its availability. To solve the problems, in this paper we propose a blockchain-based electronic voting system. A blockchain is a distributed database, where the complete data is shared among all participants in the network. A blockchain system by its nature has several advantages that suit an electronic voting system. Its distributed architecture provides high availability to the system because it does not rely on a centralized server. As all participants have complete data, the protocol allows them to verify each block that is appended to the chain. We try to combine the double envelope encryption technique and blockchain technology for our proposed electronic voting system.
