According to ChainCatcher news, the China Securities Regulatory Commission (CSRC) has released 8 financial industry standards, including the "Communication Guidelines for General Blockchain Infrastructure in Regional Equity Markets." The financial industry standard "Communication Guidelines for General Blockchain Infrastructure in Regional Equity Markets" specifies the communication guidelines between the general financial infrastructure based on the "Regulatory Chain - Local Business Chain" dual-layer architecture and the existing systems of regional equity markets. It clarifies the systems, main data objects, business scenarios, and operational instructions involved in 6 types of communication agreements: user registration agreement, asset registration agreement, fund mapping agreement, asset mapping agreement, transfer management agreement, and settlement management agreement. The implementation of these standards is beneficial for fully leveraging the supporting role of the "Regulatory Chain - Local Business Chain" dual-layer blockchain architecture for existing business systems and promoting the transformation and integration of these systems.
