Abstract

In this paper, we propose a secure blockchain-based electronic voting (e-voting) system with distributed authorities. Specifically, we employ threshold blind signature to distribute trust for registration; and threshold ElGamal decryption to distribute trust in ballots tallying. Combining these techniques with decentralized blockchain technology, our system can achieve verifiability, eligibility, fairness and anonymity with reduced trust. We also analyze the efficiency of our system by implementing the proposed e-voting system on a typical laptop for performance evaluation. Our system is efficient enough to be employed in practice based on the experiment results.
