Electronic Voting System Using Blockchain Technology

The election of a country holds significant importance, as it plays a pivotal role in the advancement and growth of a nation. Ensuring the safety and integrity of an election is a concern closely tied to national security. Electoral mechanisms in Sri Lanka and many other regions remain conventional and vulnerable. Despite the evolution of democracy, voting processes continue to rely on manual methods using paper ballots and pens. Although e-voting machines have emerged, these systems carry a substantial risk of manipulation and are susceptible to issues such as malfunction and breakdown, as well as unauthorized breaches. Addressing these challenges can be achieved by embracing cutting-edge technology, specifically blockchain, to establish a voting procedure that is both dependable and transparent. This paper presents a voting platform built upon the principles of blockchain with the aim of digitalizing the voting process while ensuring dependability, security, and user-friendly functionality. The ballots submitted by voters are recorded on the blockchain, making them immutable and safeguarded against possible manipulation. The system's capacity can be expanded to suit the needs of any election. Participants can access the system using biometric authentication methods, which will make the voting process more secure. Therefore, this system illustrates the potential of utilizing blockchain technology, including distributed systems, Ethereum, and smart contracts, to provide a secure, trustworthy, and transparent voting system for contemporary elections.
