A Secure E-Voting System Using Blockchain Ethereum Technology and Smart Contracts

Abstract: Ensuring free and fair elections is the foundation of democratic nations, but conventional voting systems are still susceptible to manipulation, fraud, and inefficiencies. With the advancement of digital infrastructure, electronic voting (evoting) has become a reality, but usually at the expense of transparency and security because of centralized control. Blockchain technology, and specifically Ethereum with its smart contract feature, provides a chance to transform voting systems through decentralization, immutability, and end-to-end verifiability. This suggests a next-generation e-voting system on the Ethereum blockchain with secure voter authentication, transparent vote casting, and smart contract-based automated result counting. Experimental results confirm the system's fraud resistance, scalability for medium-sized elections, and capability to present realtime, tamper-proof election results.
