Blockchain-Based Online Voting System

Abstract

Digital voting is the use of electronic device, such as voting machines or an internet browser to cast vote. It has disadvantages like security of data and potential attacks such as DoS and DDoS attack. One way to solve these security credentials problems is through the blockchain technology. Blockchain technology embraces a decentralized system and the entire database is owned by many users that overcome the disadvantage of centralized system. The existing system has many security, confidentiality, and anonymity issues. These issues can be resolved by using blockchain technology. Here in the proposed system Ethereum blockchain is used, which enables smart contracts. Smart contracts can be written with solidity, which is object oriented programming language. The outcome of the project is it provides privacy by keeping individual’s vote secret by providing a unique transaction id to each voter. Eligibility is made once to vote and the transaction will be highly secure and encrypted.
