Abstract: A blockchain consensus method includes: an accounting node generating a block and broadcasting verification information of the accounting node to other accounting nodes among N accounting nodes; receiving and verifying acknowledgement information broadcast by the other accounting nodes; and adding the block to a blockchain when the received acknowledgement information satisfies a second set condition. The N accounting nodes are determined according to coin age information carried in election requests broadcast by M election nodes. The acknowledgement information broadcast by the other accounting nodes is generated and broadcast by a first accounting node when received preparation information of a second accounting node meets a first set condition; the preparation information of the second accounting node is generated and broadcast by the second accounting node when validating the verification information; and each of the first accounting node and the second accounting node is any one of the other accounting nodes.
