Next-Gen Voting: A Blockchain-Based e-Voting System for Fast and Secure Digital Elections

The electronic voting system has garnered much interest in ensuring vote election processes that are secure, transparent, and efficient. Most conventional voting systems have problems of security, privacy, and verification issues involving the integrity of votes and authentication of voters. The paper proposes the development of an e-voting blockchain system enhanced with biometric authentication, ensuring verification of the identity of voters, and asymmetric encryption combined with digital signatures to ensure vote integrity. The consensus algorithm used in this research is a proof-of-work algorithm that has a moderate difficulty level of 3. Validators are in competition to create a hash suitable for the block. This concept ensures the immutability of data. This paper is designed so that each block will handle 100 transactions-in other words, votes-added after verification by a digital signature. Experimental results prove the resource efficiency of the system: optimal CPU and GPU usage, validation speed, and even power consumption scale linearly with block counts such as, the average validation time has remained constant at 0.03-0.04 seconds, with about no CPU and GPU utilization, even when the blocks increased up to 1000. The proposed system offers a promising solution to the security and efficiency challenges inherent in electronic voting, demonstrating potential as a reliable and scalable option for contemporary electoral processes. This approach underscores the viability of integrating blockchain and biometric technologies to strengthen the integrity and transparency of voting systems.
