Towards a Blockchain Voting Roadmap

Recent concerns about election integrity provide motivation for more secure voting. Electronic voting has been projected for some time but still not widely adopted. Blockchain features like transaction authentication, block integrity, consensus mechanism has some potential to form part of a solution. Voting systems have disparate requirements, especially in terms of off-chain processes (e.g., voter authentication and non-coercion processes). Contributions of this article include classification of voting applications by governance and decisional context, 4W's framework for analysis of normal operations, technology roadmap considerations for blockchain voting, and identification of areas for further study.
