E-Voting Application Development Utilizing Blockchain Technology: Evaluation of Blockchain's Usage to Solve E-Voting Data Security Problem

E-Voting is an important role in voting decisionmaking. However, E-Voting has many weaknesses such as lack of data transparency and security in the application, which can reduce public trust. Therefore, the author intends to apply blockchain technology as a method that can solve this problem. The author proposes a solution by utilizing blockchain technology on the Ethereum network and utilizing smart contract technology. By implementing blockchain technology, every voice transaction will be recorded in a decentralized manner, ensuring data integrity and security without the possibility of manipulation. The research methods used are literature review, needs survey, design, development, comparison and evaluation. The result achieved was an evoting application based on a website platform by implementing blockchain technology that can ensure data security.
