# 🎓 Online Learning Platform with NFT Certificate Verification
A full-stack application that enables learners to join online courses and receive NFT-based certificates stored and verified on the Ethereum Sepolia testnet. This project was built as part of a graduation thesis at the University of Sciences, Hue University.
---
## 📚 Overview
The platform aims to provide a reliable and interactive online learning experience, combining:
* Course management system for learners and instructors.
* NFT-based certification with verification on-chain.
* Use of blockchain (Sepolia), IPFS, and AI Assistant.
* Real-time updates and decentralized storage for integrity and transparency.
---
## ✨ Features
### Learners:
* Register & login securely
* Browse, enroll in courses
* Track learning progress
* Receive NFT certificates
* Validate certificate authenticity on-chain
### Instructors:
* Apply to become an instructor
* Create, update, and publish courses & lessons
### Admin:
* Manage users, courses, categories
* Review instructor applications
* View platform analytics
### NFT Certification:
* Issued as ERC-721 tokens
* Metadata stored on IPFS
* Soulbound (non-transferable)
* Verifiable on the Sepolia blockchain

## 🏠 System Architecture
---
## 🚀 Quick Start
### 🌐 Local Development
```bash
docker-compose up --build
```
### 🔋 Deploy Smart Contracts
```bash
npx hardhat run scripts/deploy.js --network sepolia
```
---
## 🖊️ Smart Contracts
### Features:
* ERC-721 standard
* Metadata stored on IPFS
* Hash verification for integrity
### Example:
```solidity
function verifyMetadataHash(bytes32 hash) external view returns (bool) {
return _usedHashes[hash];
}
```
---
## 📅 Certificate Lifecycle
1. Learner completes course
2. System generates metadata + image
3. Uploads to IPFS via Pinata
4. Mints NFT using `mint()` in smart contract
5. Metadata hash stored on-chain
6. Learner receives certificate in wallet
7. Verifier hashes metadata & checks on-chain
