E-Voting using Ethereum Blockchain

Abstract

The revolutionary concept of blockchain has given a rise to multiple facets of secure, accountable, online services. We witness the rise of E-voting as a critical topic related to online services. Blockchain with smart contracts emerges as a good candidate to use in the development of safer, cheaper, more secure, more transparent, and easier to use e-voting systems. Ethereum and its network are one of the most viable candidates for the implementation of an e-voting system using blockchain, due to their consistency, widespread use, and provision of smart contracts logic. An e-voting system must be secure, as it should prevent duplication of votes while being fully transparent and protecting the privacy of the voters involved. In this work, we have implemented and tested a sample voting web - application as a smart contract for the Ethereum network using the Ethereum wallets and the Solidity language. Eventually, when elections are held, the Ethereum blockchain will store votes and voting results. Users can connect their Ethereum wallet and vote for the candidate they want to, and these transaction requests are processed by the consensus of each Ethereum node. These agreements create a transparent voting environment.
