Wherein, the file transmission request is formulated by the executing miner node 31 according to the user information of the user node 2 sent by the server 1. The executing miner node 31 is any one of the N miner nodes 3 screened by the server 1.
Step S15, if the query result is that the execution file is only stored internally, the user node 2 establishes a data communication connection with the executing mineworker node 31, and sends the execution file to the executing mineworker node 31 after the connection is successful, otherwise, sends the node information of the backup mineworker node 32 in which the execution file is stored to the executing mineworker node 31, and sends the verification information corresponding to the executing mineworker node 31 to the backup mineworker node 32.
