Data isolation access control method and system based on alliance chain and related equipment

The invention discloses a data isolation access control method and system based on an alliance chain and related equipment. The method comprises the following steps: receiving a processing operation request of a user for target alliance chain data; when the user needs to process the data of the alliance chain, permission verification can be performed on the user, and it is determined that the user has the permission to process the data. Specifically, authority data of a user can be determined, and then authority verification is performed on a processing operation request of the user based on the authority data. And when the permission verification is passed, indicating that the target alliance chain data can be processed based on the processing operation request. Through the method provided by the embodiment of the invention, different processing permissions of the users to the alliance chain data can be determined for different users, isolated access of the data is realized, an operation and maintenance end
