Claim 2:
3. The method according to claim 1, wherein each of the plurality of branch blockchains has a sequence number, and
the selecting the branch blockchain for recording the target data block comprises:
determining, 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;
selecting a branch blockchain having a smallest sequence number from the determined first branch blockchains as the branch blockchain for recording the target data block; and
based on all of the first branch blockchains having a sequence number smaller than the sequence number of the second branch blockchain, selecting, from the first branch blockchains, a first branch blockchain having a smallest sequence number as the branch blockchain for recording the target data block.
