## 🎓 Learning Path

### Beginner: Just want to see it running
```
1. ./test-docker.sh
2. Open http://localhost:5173
3. Login and explore
```

### Intermediate: Want to understand the code
```
1. Read BLOCKCHAIN_IMPLEMENTATION.md
2. Review backend/app/blockchain/
3. Review frontend/src/blockchain/
4. Run ./verify-integration.sh
```

### Advanced: Want to customize or deploy
```
1. Study smart contract pseudocode
2. Understand oracle system
3. Review all service implementations
4. Read production deployment notes
5. Plan Web3 provider integration
```

## 🔑 Key Concepts

### Hybrid Architecture
- **On-Chain**: Escrow, settlement (trustless)
- **Off-Chain**: User data, search, notifications (fast UX)
- **Sync**: Event indexer keeps database updated

### Oracle Network
- 5 independent nodes
- 3 of 5 consensus threshold
- Fetches results from external APIs
- Cryptographic signature verification

### Transaction Flow
