Voting has been a fundamental part of the democratic system as it allows individuals to voice their opinions. Over the past few years, voting turnout has diminished as concerns regarding security, privacy, accessibility and integrity have been escalated. In order to address these issues, e-voting was introduced; however, only a few countries managed to use the application due to cost and central authority approvals. Hence, blockchain technology is an emerging platform as it allows decentralization through the use of distributed technology, expanding industries and processes. In this chapter, the researchers will discuss the significance of blockchain e-voting applications as well as provide details of the issues faced by current blockchain technologies. A comparative analysis of existing mechanisms is also provided in order to understand and mitigate the gaps before fully adopting blockchain technologies for e-voting applications. Thus, this chapter will be a kind of roadmap for blockchain-based e-voting applications to improve the current voting practices and processes.
