Cross-Chain Blockchain Voting System with NFT-Based Authentication

Abstract

Traditional voting systems face numerous challenges, including security vulnerabilities, transparency issues, and operational inefficiencies, which undermine public confidence in electoral processes.Blockchain technology offers a promising solution with its immutable, decentralized, and cryptographically secure framework, addressing these critical issues.This paper presents a blockchainbased voting system implemented across multiple Ethereum Virtual Machine (EVM) platforms, including Binance Smart Chain, Fantom, Polygon, and Celo.The system leverages smart contracts for secure vote management and Non-Fungible Tokens (NFTs) for voter authentication, ensuring the uniqueness and authenticity of each vote.Our research includes a comprehensive evaluation of the system's performance, focusing on transaction costs, processing speed, and scalability.The findings demonstrate the potential of blockchain technology to efficiently handle large volumes of electoral data while maintaining security and integrity, thereby enhancing the reliability and transparency of voting systems.
