Implementing a Mobile Voting System Utilizing Blockchain Technology and Two-Factor Authentication in Nigeria Temidayo Peter Abayomi-Zannu, Isaac Odun-Ayo, Barka Fori Tatama and Sanjay Misra Abstract The voting system in Nigeria has always been filled with different forms of manipulation, and m-voting was suggested as the solution but has a major problem which is securely storing the casted votes. Blockchain was proposed to mitigate this problem and with the utilization of two-factor authentication to prevent illegible voters from casting their votes. The objective of this paper is to develop a mobile voting system that utilizes two-factor authentication to authenticate the voters and blockchain technology to securely store the votes. The system was then evaluated using the ISO 9241-11 usability model, and the results showed that the proposed system had a good usability rating which implies that it can be utilized in a voting procedure.
