Abstract: The disclosure provides example block generation methods. One example method includes that when a first blockchain node is a leader, packing, by the first blockchain node, a leader-elected transaction in a transaction pool into a first block, where the leader-elected transaction records a leader proof of the first blockchain node. The leader proof records a voting state in which each of the plurality of second blockchain nodes votes on the first blockchain node, and the voting state indicates whether a vote is a positive vote or a negative vote. Sends the first block to the plurality of second blockchain nodes, so that the first blockchain node and/or the second blockchain nodes perform fork processing based on the leader proof.
