Abstract

The invention relates to the technical field of block chains, and particularly discloses a block chain data consensus method and device in a Byzantine scene, and the device comprises a block producer queue management module, a block production module, a block pre-submission module, a block submission module, a block synchronization module, a block chain bifurcation processing module, and a block irreversible processing module. According to the consensus method, different modules are endowed with different functions; according to the invention, distributed data consensus in a traditional Byzantine scene is asynchronized, and a two-stage synchronous confirmation mode is converted into a two-stage asynchronous confirmation mode, so that on one hand, the network bandwidth pressure when a block chain distributed system carries out data consensus can be reduced, and on the other hand, the processor time slice can be fully utilized; transaction and block processing can be performed at each moment, so that the overall throughput of the block chain network is improved.

Description

technical field [0001] The present invention relates to the field of block chain technology, and more specifically, to a block chain data consensus method and device in a Byzantine scene. Background technique [0002] The blockchain network is composed of distributed blockchain nodes, which exchange data through an open network, and usually run service mirrors independently by the participants. It is a distributed system in a typical Byzantine scenario. [0003] The distributed system data consensus in the Byzantine scenario usually uses the BFT consensus algorithm and its variant consensus algorithm to achieve data transmission and data consensus, which is generally divided into two stages of Prepare-Commit. [0004] The traditional BFT consensus algorithm requires more network data interaction, and the speed of reaching consensus will be affected by network delays. During this period, the blockchain nodes based on this consensus algorithm will not be able to perform subseq...
