Review on blockchain-based e-voting systems

A democratic society is built on the concept of voting. The majority of nations need voters to physically attend elections and cast paper ballots. That aforementioned constraint, among others, incurred rising administrative costs and declining voting turnout. Due to that, e-voting emerged as a mechanism that uses technology to let citizens cast votes for candidates or participate in group decision-making. The e-voting technology provides faster results, lessens human error, and more ease for persons with disabilities. Due to the process's lower cost and greater openness, e-voting has attracted a lot of interest lately. Some research has been done to create electronic voting systems that use the blockchain as a public polling system, enabling verifiability and self-tallying. The following study aims to provide using Systematic Literature Review (SLR) a thorough examination of several e-voting systems, to recognize, evaluate, and analyze prior research results in order to guide future work and to bear in mind all the needs, benefits, and downsides of the proposed solutions.
