Xora: ZKML Credit Score

Xora ZKML Credit Score is a project conceived with the vision of enabling credit lending in the blockchain realm. Presently, the majority of blockchain-based loan products are collateral-based. However, we believe in a future where unsecured credit lending will become a reality.

Xora Credit Score leverages ZKML to compute credit scores, utilizing:

• An ML model employing the XGBoost Regression Model.
• ZKML Circuit design in the Noir language.
• Execution of ZK Circuit and retrieval of prediction results through the Sindri API.
• Subgraph for indexing Credit Score Reqeust Logs

Key features include:

• Users can review their credit score calculation history on the website.
• Third-party dApps can verify a specific user's credit score through smart contracts.
• Subgraph indexing credit score history
