Abstract

Blockchain Voting System is an open-source Blockchain & Cloud Computing project. A Blockchain based secure voting system with delegation support. It is built using Java, Solidity. Key capabilities include: Clean Interface for both Election Chairperson and Voters; Support for delegation. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building a Blockchain & Cloud Computing mini project or final-year project.

1. Introduction

A Blockchain based secure voting system with delegation support.

2. Objective

A Blockchain based secure voting system with delegation support

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

3. Key Features / Modules

  • Clean Interface for both Election Chairperson and Voters.
  • Support for delegation.

4. Technology Stack

JavaSolidity
  • Web3j - Java and Android library for integration with Ethereum clients
  • Solidity compiler
  • Web3j command line client
  • NetBeans 12.2 IDE
  • Remix IDE

5. System Requirements

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

  • JDK 11 or later
  • Maven / Gradle
  • IntelliJ IDEA, Eclipse or Android Studio
  • Node.js and npm
  • Hardhat / Truffle / Remix IDE
  • MetaMask wallet with a test network
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/nisiddharth/Blockchain-Voting-System.git
cd Blockchain-Voting-System

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?
