  • Publication number: 20210297242
    Abstract: The present disclosure includes a method for processing distributed data. In the method, the distributed data of a first main body is obtained. The distributed data has a transfer identifier. The distributed data is transferred, in response to a second main body different from the first main body, to a management address based on the transfer identifier when the distributed data meets a first condition. The first condition is that the distributed data includes abnormal information. The distributed data transferred to the management address freezes transfer of the distributed data by the first main body.
