## 🏗 Architecture Overview

```
Frontend (Next.js + React) → Backend (Flask + Python) → MongoDB Database
                          ↓
                    Web3 Layer (Ethereum)
                          ↓
              Smart Contracts (Solidity) → IPFS Storage
```

**Key Components:**
- **Frontend**: Next.js 14, TypeScript, TailwindCSS, MetaMask integration
- **Backend**: Flask, TensorFlow, Web3.py, JWT authentication
- **Blockchain**: Solidity smart contracts, ERC-721 NFTs, Foundry toolkit
- **Database**: MongoDB, Redis cache
- **Storage**: IPFS for decentralized metadata
