Abstract

The invention relates to a method and system for a manufacturing department to cooperatively maintain reliable data storage based on an alliance block chain. The method comprises the following steps: S1, taking a plurality of protocol nodes as a center, and employing a distributed database and a Raft consensus technology to form an alliance block chain network; wherein each protocol node corresponds to at least one department and one distributed account book, and digital identity certificate management and data link management are carried out on the department by utilizing the protocol nodes; wherein the departments comprise a service department and a management department; s2, the management department manages application, verification, updating and revocation of the digital identity credentials of all the service departments; and S3, each service department logs in the corresponding protocol node by using the digital identity certificate, and performs data uplink and data query operation. According to the method provided by the invention, an alliance block chain technology is taken as a technical framework, and a new mode of data chaining, interaction and identity recognition management among departments is designed.
