 ### Data Flow
+
 1. User financial data is collected (with permission) from various sources
 2. Data is processed, anonymized, and stored on the blockchain
 3. AI models analyze the data to generate credit scores and risk assessments
 4. Users can view their scores and control access to their data
 5. Lenders can request access to scores for lending decisions
 
 ### AI Models
-* **Machine Learning Algorithms**: Random Forest, XGBoost, and neural networks for credit scoring
-* **Natural Language Processing**: Sentiment analysis of financial communications
-* **Time Series Analysis**: Prediction of future financial behavior
-* **Quantitative Finance Models**: Risk analysis (Value at Risk, Sharpe Ratio)
