Blockchain-Based Certificate Verification System

🚀 Project Overview

This project leverages the power of blockchain technology to revolutionize the way graduation certificates and other legal documents are verified. The primary goal is to create a secure, transparent, and decentralized platform where colleges publish certificates on the blockchain, allowing companies to verify their authenticity seamlessly.

---

🌟 Key Features

• Certificate Publishing: Colleges can upload certificates to the blockchain, ensuring they are tamper-proof and publicly verifiable.
• Instant Verification: Companies can validate the authenticity of certificates without relying on intermediaries.
• Enhanced Security: The blockchain ensures that all records are immutable and protected against fraud.
• Decentralized: Eliminates centralized points of failure, ensuring reliability and transparency.

🛠️ Tech Stack

Frontend

• React: Interactive and dynamic user interface for seamless user experience.
• JavaScript: Core functionality for user interactions and logic.

Backend

• Node.js: Handles server-side logic and API integration.
• MongoDB: NoSQL database to manage user and certificate metadata.

Blockchain Tools

• Truffle Framework: For writing, testing, and deploying smart contracts.
• Ganache: Local Ethereum blockchain network for development and testing.
• Web3.js: JavaScript library for interacting with the blockchain from the frontend.

---

📜 Workflow

1. Certificate Upload: Colleges upload certificates to the system.
2. Blockchain Integration: The certificate details are hashed and stored on the blockchain using smart contracts.
3. Verification: Companies can search for a certificate's hash to verify its authenticity instantly.
4. Immutable Records: Once published, certificates cannot be altered or deleted.
