Nir Kshetri, a professor of management at the University of North Carolina, recently stated that there are some important issues that must be resolved before the blockchain voting technology is widely adopted. The report points out that voting systems like this need to verify the identity of the voters, usually through facial recognition software to analyze avatar photos or videos. The voting system using blockchain technology is anonymous. Even experts have no way to identify every violation that may exist in online voting. Paper-based voting is well understood and easy to verify and audit.
