Abstract
This specification discloses a method and a system. The method includes: obtaining a Merkle root of one or more proposals initiated by one or more nodes associated with a blockchain; signing the Merkle root of the one or more proposals to obtain a digital signature of the one or more proposals; transmitting the digital signature of the one or more proposals to one or more nodes associated with the blockchain; receiving one or more digital signatures of the one or more proposals from one or more nodes associated with the blockchain respectively; determining that a quantity of the received one or more digital signatures is at least 2 f+1, wherein f is a maximum quantity of abnormal nodes permitted by the blockchain; and generating a proof of consensus for the one or more proposals based on the received one or more digital signatures.
