Decentralized Voting System

Abstract

1. Introduction

A decentralized voting system using Ethereum blockchain for secure and transparent elections, with features like user authentication and real-time result tracking.

2. Objective

A decentralized voting system using Ethereum blockchain for secure and transparent elections, with features like user authentication and real-time result tracking.

This project demonstrates how JavaScript, Ethereum can be applied to a real-world Blockchain & Cloud Computing problem.

3. Key Features / Modules

• Implements JWT for secure voter authentication and authorization.
• Utilizes Ethereum blockchain for tamper-proof and transparent voting records.
• Removes the need for intermediaries, ensuring a trustless voting process.
• Admin panel to manage candidates, set voting dates, and monitor results.
• Intuitive UI for voters to cast votes and view candidate information.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Node.js (LTS) and npm
• A modern web browser
• VS Code or any code editor
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/Krish-Depani/Decentralized-Voting-System.git
cd Decentralized-Voting-System

1. Open a terminal.
2. Clone the repository by using the command
3. Download and install Ganache.
4. Create a workspace named developement, in the truffle projects section add truffle-config.js by clicking ADD PROJECT button.
5. Download Metamask extension for the browser.
6. Now create wallet (if you don't have one), then import accounts from ganache.
7. Add network to the metamask. ( Network name - Localhost 7575, RPC URl - http://localhost:7545, Chain ID - 1337, Currency symbol - ETH)
8. Open MySQL and create database named voter_db. (DON'T USE XAMPP)

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a CI/CD pipeline with GitHub Actions
• Deploy to a public test network or cloud free tier
• Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
