Title:
CONSENSUS METHOD AND APPARATUS, AND BLOCKCHAIN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/040364
Kind Code:
A1
Abstract:
Provided in the embodiments of the present disclosure are a consensus method and apparatus, and a blockchain system. A primary directly broadcasts, in a system, a transaction hash list that comprises a hash value of at least one unverified transaction, so that a backup and the primary synchronously verify the at least one unverified transaction, and the backup saves a first verification result that is obtained by means of verification and a first hash value of the at least one unverified transaction. After completing verification, the primary carries an obtained second verification result and a second hash value of the at least one unverified transaction in a pre-prepare message and broadcasts same, so that the backup searches for the first verification result on the basis of the second hash value, and broadcasts a prepare message when the second verification result is the same as the found first verification result, so as to enter a subsequent consensus stage and complete consensus processing. In this way, the primary and the backup can synchronously verify a transaction that needs to be on-chained in the present round of consensus, thereby facilitating the acceleration of a consensus procedure and improving the consensus efficiency.
