Design and Simulation of a Blockchain-Based Voting System Using Python

Blockchain technology has gained significant attention for its ability to provide transparency, immutability, and security in digital systems. This study aims to design and simulate a secure, tamper-resistant voting system using blockchain principles implemented in Python. The system leverages core blockchain components such as cryptographic hashing, block chaining, and decentralized record-keeping to prevent electoral fraud and ensure voter anonymity. A proof-of-concept model is developed using Python libraries such as hashlib, Flask, and pycryptodome to simulate voting, validate voter identity, and record votes as immutable blocks. The proposed system incorporates a lightweight consensus mechanism and voter ID encryption to demonstrate the integrity and security of the election process. Preliminary simulations suggest that such blockchain-based systems can significantly improve trust in digital elections, reduce human intervention, and resist tampering. This paper contributes to the field by providing a practical, educational-level Python-based model suitable for academic, civic, or institutional adaptation.
