Secure Voting System Using Blockchain Technology: A Decentralized Approach to Enhance Electoral Integrity

The conventional electronic voting machines often have problems like, centralized vulnerabilities, lack of transparency, prone to single-point-of-failure attacks, as well as high administrative overhead for voter verification. This paper presents a solution: A Decentralized e-voting framework created on the Ethereum Virtual Machine (EVM) that tackles these issues through the integration of blockchain immutability and mobile-native biometric authentication. With the medium this project, we propose a system that implements Solidity smart contracts to manage election lifecycles and a React Native frontend for User friendly UI and cross-platform accessibility. The key innovations such as a cycle-based state management mechanism for optimizing the contract reusability and a cryptographic credential-hashing protocol that safeguards voter identity without the need for high-cost third-party verification services.
