Design and Analysis of Blockchain-based E-voting Protocols

Abstract

Voting is the most fundamental cornerstone in the context of representative democracy. With the advent of the internet technologies, various types of e-voting mechanisms have emerged. Building an e-voting system capable of performing as good as a traditional voting system is a very challenging task. On the positive side blockchain technology inherently provides critical security properties to design secure e-voting protocols. In this work, we have studied decentralized boardroom scale e-voting protocols designed by McCorry et al. in 2017. We have extended their work in multiple directions. Our protocol supports (A) arbitrary number of candidates1 ; (B)majority-base countings; (C) voting absentation (D) we also did a theoritical analysis of all the protocols.
