Blockchain-Based Voting Systems: Enhancing Security and Transparency in Digital Voting Systems

Description

This project provides an innovative solution for conducting transparent and secure elections leveraging blockchain technology. It's an Ethereum-based voting system that ensures the integrity and reliability of the voting process.

Voters are provided a unique PIN at the voting point after manual verification by an officer. Upon entering the PIN in the kiosk, voters are presented with a list of candidates. Post selection, the system acknowledges the vote with a success message and resets for the next voter.

Key features include:

• Commissioner Access: Allows creating elections, adding candidates, starting & ending elections, and viewing results.
• Admin Access: Grants rights to enable the voting process.
• Secure PIN-Based Voting: Ensures that only authorized voters can cast their vote.

Tech Stack

• Blockchain: Ethereum network, with smart contracts developed using Solidity.
• Frontend: React.js for a dynamic and responsive user interface.
• Backend: Node.js with Express.js framework.
• Database: MongoDB, primarily for user authentication and login functionalities.

Prerequisites

Before you begin, ensure you have the following installed:

• Node.js
• npm
• Ganache CLI
• Truffle

3. Install the necessary dependencies:

   npm install

Running the Application

Follow the steps below to run the application:

1. Start the server

cd server
npm run start-watch

2. Start Ganache CLI

In a new terminal:

ganache-cli -chainId 1337

3. Compile and Migrate the Contracts
