PANews reported on March 19 that according to CoinDesk, Untangled Finance and Moody's Ratings have completed a proof of concept to transfer credit ratings to the chain by testing a system that allows decentralized access to Moody's financial data. The proof of concept conducted on the Polygon Amoy testnet integrated Moody's ratings into Untangled Finance's risk oracle Credio. The system uses zero-knowledge proof (ZKP) technology to allow credit ratings to be securely published, updated, and withdrawn on the chain while protecting proprietary information. This development can make risk assessment more transparent and efficient, allowing DeFi protocols and other blockchain-based applications to integrate real-time credit data without relying on centralized intermediaries.
