Claim 13:
14. The leader accounting node according to claim 12, wherein each of the plurality of branch blockchains has a sequence number, and
the first branch blockchain selection code comprises:
determination subcode configured to cause at least one of the at least one processor to determine, from the first branch blockchains, first branch blockchains of which sequence numbers are greater than a sequence number of a second branch blockchain, the second branch blockchain being a branch blockchain that records a previous data block of the target data block;
first selection subcode configured to cause at least one of the at least one processor to select a branch blockchain having a smallest sequence number from the first branch blockchains, determined by the determination subcode, as the branch blockchain for recording the target data block; and
second selection subcode configured to cause at least one of the at least one processor to, based on all of the first branch blockchains having a sequence number smaller than the sequence number of the second branch blockchain, select, from the first branch blockchains, a first branch blockchain having a smallest sequence number as the branch blockchain for recording the target data block.
