Decentralized Voting System Using Blockchain Technology

📌 About the Project

The Decentralized Voting System Using Blockchain Technology is a blockchain-based voting application developed as an academic project.

The main purpose of this project is to demonstrate how blockchain and smart contracts can be used to make voting more secure, transparent, and tamper-resistant.

The system uses Ethereum blockchain technology and allows users to connect their wallet using MetaMask and cast their votes through a web interface.

🔗 Network Configuration

Sepolia Test Network

The project can be tested on the Ethereum Sepolia test network using test ETH.

Ganache Local Network

For local testing:

RPC URL: http://localhost:7545
Chain ID: 1337
Currency: ETH

🦊 MetaMask

MetaMask is used to connect the user's blockchain wallet with the voting application.

The user can:

1. Open MetaMask.
2. Connect the wallet to the required network.
3. Open the voting application.
4. Connect the wallet.
5. Select a candidate.
6. Confirm the transaction in MetaMask.

Never share or upload your MetaMask private key or recovery phrase.

📜 Smart Contract

The voting logic is implemented using a Solidity smart contract.

The smart contract manages the voting process and records voting-related information on the blockchain.

The contract can be developed and deployed using Remix IDE.

---

🗄️ Database

The project also uses MySQL for supporting application data.

Database name:

voter_db

XAMPP is not required for this project. MySQL can be used directly.
