## 🎯 Why Antigravity?
| Challenge | Our Solution |
|-----------|--------------|
| ❌ AI models lack **data provenance** | ✅ L8 blockchain-verified ownership (IPFS + Numbers Protocol) |
| ❌ Training data has **no standard format** | ✅ L0-L8 universal annotation schema |
| ❌ Data value is **hard to quantify** | ✅ **💰 Value Scoring Engine** - Auto USD pricing based on L5/L7 metrics |
| ❌ No **commercial licensing** metadata | ✅ L6 embedded licensing & royalty tracking |
| ❌ Manual labeling is **slow & expensive** | ✅ Gemini-powered auto-annotation |
