Inventor: WU SIJIN
IPC: G06Q40/06
Filed: 2017-07-27
Abstract: Provided is a block chain credit loan matching system. A fund demanding party submits loan application data on a block chain and then a registered credit evaluation mechanism performs evaluation and listing on the loan applicant and the application content; a bank, a factoring company and other fund supplying parties provide a corresponding loan interest rate and a loan amount quotation on the block chain with respect to the evaluation and listing information provided by the credit evaluation mechanism; and the fund demanding party selects one or more fund supplying parties on the block chain within a specific time period so as to form a credit loan contract to obtain a fund. The loan application listing information and the credit loan matching information are written in an intelligent contract by using block chain technology, so that the financing demand of the fund demanding party can be transferred to the fund supplying parties in the largest range within the shortest time period. The fund demanding party and the fund supplying parties are enabled to exert the production efficiency of the capital to the greatest extent by means of biding, so that the information loss and the time cost caused by a conventional information transfer method can be reduced.
