We present a secure approach for maintaining and reporting credit history records on the Blockchain. Our approach removes third-parties such as credit reporting agencies from the lending process and replaces them with smart contracts. This allows customers to interact directly with the lenders or banks while ensuring the integrity, unmalleability and privacy of their credit data. Additionally, each customer has full control over complete or selective disclosure of her credit records, eliminating the risk of privacy violations or data breaches. Moreover, our approach provides strong guarantees for the lenders as well. A lender can check both correctness and completeness of the credit data disclosed to her. This is the first approach that can perform all credit reporting tasks without a central authority or changing the financial mechanisms.
