Embodiment Construction

[0048] like Image 6 As shown in the figure, this scheme focuses on solving the bifurcation problem in the PPoV algorithm, and adopts the technical problems of synchronizing its own height and delaying block drop.

[0049] When the PPoV algorithm performs transaction processing and packaging, it is responsible for the rotating billing node elected by the verification nodes. There is only one rotating billing node in each period of time, and the rotating billing node rotation also requires the current It is easy to cause a problem that if the rotating accounting node is down, the process of calculating the serial number of the next rotating accounting node cannot be continued, and the PPoV system will be paralyzed. like figure 2 shown. In addition, when the following two partitions occur in the network, there will also be downtime problems: ① Most of the verification nodes and rotating accounting nodes are isolated in one partition, and a few other nodes are isolated in anot...

Abstract

The invention is suitable for the field of block chain technology improvement, and provides a method and system for eliminating a bifurcation problem in a parallel voting proof consensus algorithm, and the method comprises the steps: S1, judging whether a network generates a partition or not before a block group is submitted by an alternate accounting node of a parallel voting proof consensus; s2, after the network is recovered, judging whether the height a of the last state block group of the node is higher than the height of another legal block group or not; and S3, the minority node requests information of the block group with the height of a from the majority node, the check is passed, the block group with the height of a is rewritten, and the network is recovered to be normal. The bifurcation problem of the PPoV consensus algorithm caused by network partition is improved by delaying block falling and timing synchronization block group height, and the availability of the PPoV consensus algorithm is improved. In an actual application scene, the improvement can well avoid the problems of transaction data chaos and the like caused by chain bifurcation.

Description

technical field [0001] The invention belongs to the field of block chain technology improvement, and in particular relates to a method and a system for eliminating the bifurcation problem in the parallel voting proof consensus algorithm. Background technique [0002] In recent years, with the acceleration of industrial informatization, digitization, and networking and the popularization of intelligent terminals, the Internet has become one of the driving forces for the development of human society and is closely linked to people's lives. In 2018, the total number of Internet users in China reached 800 million, the number of Internet users worldwide exceeded 4 billion, and the amount of data generated on the Internet exceeded 5 trillion bytes every day. The anonymity and low threshold of the Internet not only facilitate people's life, but also provide a breeding ground for malicious programs such as Trojans and viruses. In order to resist various attack methods, more and mor...
