Election Voting Blockchain

Abstract

1. Introduction

Elections and voting are the basic mechanisms of a democratic system. There have been various attempts to make modern elections more flexible by using digital technologies. Basic characteristics of free and fair elections are intractability, immutable, transparency and the privacy of the involved actors. This corresponds to a few of the many features of blockchain-like decentralized ownership, the immutability of chain, anonymity and distributed ledger. My problem statement is “To create a robust blockchain based election mechanism that will not only be reliable and secure but also flexible according to the current needs”. The main aim of this proposal is to present a robust blockchain-based election mechanism that not only will be reliable but also flexible according to present needs.

A secured online voting system built using mongoDB, ExpressJS, ReactJS, NodeJS (MERN), Solidity (Smart Contracts), and web3JS. In this application, the admin can start elections, add candidate, manage users and end elections. The user will able to vote and see all the results of the election held till now.

npm i at the root folder. npm i in the frontend folder. Go to backend/config/ and make a file 'config.env'

2. Objective

A secured online voting system built using mongoDB, ExpressJS, ReactJS, NodeJS (MERN), Solidity (Smart Contracts), and web3JS. In this application, the admin can start elections, add candidate, manage users and end elections. The user will able to vote and see all the results of the election held till now.

This project demonstrates how JavaScript can be applied to a real-world Full Stack Web Development problem.
