Abstract: MatdaanX is a decentralized hybrid voting architecture designed to deliver secure, transparent, and reliable election processes through the integration of blockchain technology, biometrics, and IoT-based offline modules. MatdaanX is a secure and transparent electronic voting platform developed to make the election process more dependable and user friendly. The online module authenticates voters through multiple layers of verification, including facial recognition based on MTCNN, OTP verification, and digital signatures. This ensures that each vote is genuine and securely encrypted before being submitted. In regions with poor or unstable internet connectivity, the system offers an offline setup that operates using an Arduino Uno microcontroller integrated with a fingerprint sensor, keypad, and LCD display. This allows voters to cast their ballots effortlessly without relying on continuous network access, ensuring inclusive participation in all areas. Both online and offline votes in MatdaanX are securely recorded in a private blockchain network that employs SHA-256 hashing along with a Proof- of-Authority(POA) consensus model. This approach guarantees data integrity, transparency, and resistance to any form of tampering or unauthorized modification By integrating biometric verification, blockchain-based recordkeeping, and dual online-offline connectivity, MatdaanX effectively tackles major electoral challenges such as voter fraud, duplicate entries, ballot manipulation, limited accessibility, and delays in result compilation. Overall, it offers a transparent, verifiable, and inclusive framework for conducting elections in a modern democratic environment.
