Credit asset block chain construction method and system

The invention discloses a credit asset block chain construction method and system. The implementation method comprises the following steps: based on a Web system, establishing a block chain underlyingplatform, designing an operation and maintenance management system, deploying a service intelligent contract, setting a front sdk based on the service content of the service intelligent contract, andproviding APIs called by a block chain for Web services of a Web server and other node-free access parties and other interfaces. Based on the method provided by the invention, a set of credit asset block chain system for realizing the method provided by the invention can be constructed, a block chain platform is accessed in a special line mode to carry out service operation, a Web application system, a service intelligent contract and a front sdk are added, a block chain basic platform is transformed, and a block chain operation and maintenance management platform is optimized. 本发明公开了一种信贷资产区块链构建方法及系统，实现包括：基于Web系统，搭建区块
