Method, system, computer system and storage medium of uploading blockchain data

A computer system comprising a sub-institution node group and a master institution node of a master institution corresponding to the sub-institution;

• the sub-institution node group comprises a plurality of nodes, the plurality of nodes comprises a first memory and one or more first processors, the first memory has computer-readable instructions stored therein which, when executed by the one or more first processors, cause the one or more first processors to perform:
• receiving a data upload request sent by a sub-institution;
• looking up a node in an idle state in the sub-institution node group according to the data upload request;
• and
• receiving data uploaded by the sub-institution through the node in the idle state and then uploading the received data to a blockchain temporary storage area;
• the master institution node of the master institution corresponding to the sub-institution comprises a second memory and one or more second processors, the second memory has computer-readable instructions stored therein which, when executed by the one or more second processors, cause the one or more second processors to perform:
• downloading the data uploaded by the sub-institution from the temporary storage area, and then uploading the downloaded data to a blockchain data storage area.

One or more non-transitory computer-readable storage medium having computer-readable instructions stored therein which, when executed by one or more first processors, causing the one or more first processors to perform:

• receiving a data upload request sent by a sub-institution;
• looking up a node in an idle state in the sub-institution node group according to the data upload request;
• and
• receiving data uploaded by the sub-institution through the node in the idle state and then uploading the received data to a blockchain temporary storage area;
• when executed by one or more second processors, the computer-readable instructions cause the one or more second processors to provide:
• downloading the data uploaded by the sub-institution from the temporary storage area, and then uploading the downloaded data to a blockchain data storage area.
