A Survey on Decentralized Voting System Using Blockchain Technology

Abstract: A decentralized voting system utilizing blockchain technology offers a transformative approach to traditional election processes. This innovative method addresses several challenges, including low voter turnout, security vulnerabilities, lack of transparency, potential vote tampering, and delays in result processing. This paper focuses on the design and development of a smart contract-based online voting system, leveraging the Ethereum blockchain as its foundation. The proposed system eliminates the necessity for intermediaries by utilizing blockchain's immutable and distributed ledger, thereby securing votes and facilitating a fully auditable voting process. Smart contracts are employed to automate voter registration, ballot generation, and vote counting, which helps minimize errors and enhance operational efficiency. Furthermore, the Ethereum network enforces a one-vote-per-voter policy through the Gas token mechanism, effectively preventing duplicate voting and ensuring the integrity of elections. A proof-of-concept application is presented and tested with simulated voting data, demonstrating the system's capability to maintain anonymity while ensuring the integrity of the voting process. This research highlights the potential of blockchain technology to bolster voter confidence, increase participation, and reduce election costs.
