Introduction

I. INTRODUCTION

Electronic voting (e-voting) systems have the potential to revolutionize the way we conduct elections by making the process more efficient, transparent, and accessible to a wider range of voters. However, the use of traditional e-voting systems has been marred by concerns over security, privacy, and transparency. In recent years, blockchain technology has emerged as a promising solution to these issues by providing a secure, decentralized, and transparent platform for e-voting.

Several studies have examined the potential of blockchain technology for e-voting systems. For instance, in their paper "A Blockchain Based Voting System",[1] Böhme et al. (2015) proposed a blockchain-based e-voting system that provides end-to-end encryption and a decentralized verification mechanism to ensure the integrity of the voting process. Similarly, in their paper "E-Voting using Blockchain Technology",[2] Kshetri and Voas (2018) argue that blockchain technology can enhance the security, privacy, and transparency of e-voting systems by using cryptographic techniques to ensure the anonymity and integrity of the voting process.

While these studies provide valuable insights into the potential of blockchain technology for e-voting systems, there is still a need for a comprehensive survey of the current trends and future prospects of using blockchain technology for e-voting. In this survey report, we aim to fill this gap by providing a comprehensive overview of the key features, benefits, challenges, and future prospects of using blockchain technology for e-voting systems.
