摘要： The present application provides a blockchain consensus method, apparatus and device, and the method includes: dividing (S201) transaction information in a transaction pool into N transaction information sets, where N is a natural number greater than 1; performing (S202) consensus on the N transaction information sets in parallel, to obtain a first consensus result corresponding to each transaction information set; and determining (S203), according to a first consensus result corresponding to a first i transaction information set, a second consensus result corresponding to an i-th transaction information set, where i takes 1, 2, ..., N-1 and N in sequence. Since the second consensus result corresponding to the i-th transaction information set is determined according to the first consensus result corresponding to the first i transaction information set, the accuracy of the consensus results thus can be ensured. Moreover, under the premise of ensuring the accuracy of the consensus results, performing consensus on the N transaction information sets in the transaction pool in parallel is realized, consensus efficiency is increased, and thereby an overall performance of a blockchain network can be improved.
