An Efficient and Secure Voting Mechanism Build on Blockchain

Elections are a vital aspect of democratic states, and their integrity is a fundamental element in guaranteeing the democratic process’s equity. Since the development of the blockchain technology, potential solutions to secure, transparent voting has emerged. Alternate voting systems offered by previous public blockchain voting systems however suffer scalability, privacy and access problems. In this paper, we propose a hybrid blockchain voting system that utilizes the strengths of public and private blockchains. We make our scheme scalable, secure and transparent, with the privacy and availability of voters being preserved. In order to ensure the security and scalability of the system, a hybrid consensus mechanism based on proof of work and proof of stake is adopted. In addition, we use an original zero-knowledge proof technique to ensure voter privacy, whilst maintaining security in the voting. Additionally, we provide two user-friendly interfaces to facilitate the accessibility and participation of voters and two One Time Passwords, one for voter login and one for vote verification. The recommended system could reshape voting and be a model for secure and reliable democratic voting operations.
