Privacy-Preserving Decentralized Voting System Using Hyperledger Fabric and IOTA

Abstract

Elections are the base for a democratic society, but there are problems like fraud tampering, slow result processing in the current voting systems. To solve these problems, this project introduces a Blockchain-Based Voting System as a scalable solution. This system uses IOTA's Tangle (a Directed Acyclic Graph model) to provide fast, scalable, and feeless transactions, making it suitable for large-scale voting. The personal details are kept secret by using Zero-Knowledge Proofs (ZKPs). A Hybrid Cloud Model is used, where sensitive data is stored securely on private servers, while the public network ensures transparency. Multi-Factor Authentication (MFA) adds an extra layer of security by blocking unauthorized access. By combining these technologies, the system makes voting tamper-proof, keeps voters anonymous, allows real-time result announcements, and protects against frauds. Overall, this solution shows how blockchain can improve the trust, fairness, and accessibility of democratic participation.
