With country’s attention on the development of “digital new infrastructure”

the use of urban substation resources to build“multi-station integration”scenarios and operation models has been initially explored and used due to the advantages of high land utilization and resource intensification. However

there are problems such as ownership

information asymmetry

privacy leakage

and high trust cost in the transaction process of multi-station transaction entities. The solutions to these problems are highly compatible with the technical characteristics of the Fabric blockchain. Therefore

aiming at the key business requirements of“multi-site integration”

based on the Fabric blockchain technology

a transaction platform architecture including multiple transaction entities participating in mutual assistance and sharing is constructed

and the back-end interaction subsystem

blockchain subsystem

and green power traceability core modules are designed to realize“Three Streams in One”of resource flow

information flow and business flow. Through the nearby integration of resources and the coordination and complementation of operation

the cost of construction and operation and the trust of transaction entities is reduced.
