PANews reported on November 23 that according to the official website of the China Securities Regulatory Commission, the China Securities Regulatory Commission issued eight financial industry standards, including the "Communication Guidelines for the General Infrastructure of Blockchain in Regional Equity Markets". The "Communication Guidelines for the General Infrastructure of Blockchain in Regional Equity Markets" financial industry standard stipulates the communication guidelines between the general financial infrastructure based on the "chain of supervision-local business chain" two-layer architecture and the existing systems of the regional equity market, and clarifies the systems, main data objects, business scenarios and operation instructions involved in the six types of communication protocols, including user registration agreement, asset registration agreement, fund mapping agreement, asset mapping agreement, transfer management agreement, and settlement management agreement. The formulation and implementation of the standard is conducive to giving full play to the supporting role of the "chain of supervision-local business chain" two-layer blockchain architecture for existing business systems and promoting the transformation and docking of existing business systems.
