Authors - K Devi Priya, P Saranya Durga, Y Sony, D Varun Sai Abstract - This paper presents a comprehensive implementation and evaluation of a secure electronic voting system built on the Ethereum blockchain platform. Proposing on Ethereum smart contracts, Proof of Stake consensus, and modern Web3 technologies and implemented the project. The implementation deals with key e-voting issues like voter authentication, ballot privacy, vote immutability and transparent auditability.We examine security threats, offer Layer2 scaling design, introduce concepts of zero-knowledge proofs in order to achieve higher privacy levels, and measure the economic benefit of deployment on different scales. In our results, we have shown that Ethereum has a significant basis to support decentralized voting systems, but scalability and cost reduction remain an important challenge to large-scale elections. The paper ends with a set of practical recommendations on the deployment of production and the main directions on the further research in the field of blockchain-based democratic systems.
