Abstract
A consensus method for a blockchain based on a Byzantine fault tolerance algorithm, includes: initiating, by a first consensus node of a consortium blockchain, a consensus proposal comprising a first proposal digest generated based on a first last block hash maintained by the first consensus node; in response to the consensus proposal, generating, by a second consensus node of the consortium blockchain, a second proposal digest based on a second last block hash maintained by the second consensus node; and not participating in, by the second consensus node, a consensus on the consensus proposal if it is detected that the first proposal digest does not match the second proposal digest.
