Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0028] Before explaining in detail the method for determining the consensus node of the blockchain provided by the embodiment of the present application, the implementation environment provided by the embodiment of the present application is firstly introduced.

[0029] See figure 1 , figure 1 It is a schematic diagram of an implementation environment shown according to an exemplary embodiment. The implementation environment includes a block chain system, the block chain system can include multiple nodes, the multiple nodes can be divided into consensus nodes 101 and candidate nodes 102, the consensus nodes can be used to generate blocks, and the candidate nodes are A node that has staked its rights and interests in the blockch...

Abstract

The invention discloses a consensus node determination method and device of a block chain, equipment and a storage medium, and belongs to the technical field of block chains. The method comprises thefollowing steps: receiving node signatures which are sent by the plurality of candidate nodes and comprise each candidate node, random numbers generated by each candidate node based on the random number seeds, and transaction data of random number verification data, verifying the node signature of each selected node; and verifying the random number generated by each selected node based on the random verification data generated by each selected node, and when the check is passed, determining the selection probability of each selected node according to the random number and the mortgage right and interest value generated by each selected node, and determining a consensus node of the next round from the plurality of selected nodes based on the selection probability. Thus, the selection probability of each selected node is determined according to the random number and the mortgage right value of each selected node, the randomness of the result is ensured, and the problem that the same nodeis selected as a consensus node is avoided.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a method, device, equipment and storage medium for determining a consensus node of blockchain. Background technique [0002] A blockchain system generally includes a plurality of nodes, and the plurality of nodes includes a consensus node, which can be used to generate blocks and broadcast blocks in the blockchain system. In the implementation, if a fixed node is always used as the consensus node, the consensus node may be maliciously attacked, thus bringing security risks to the blockchain system. Therefore, every once in a while, it is necessary to re-determine the next round of consensus nodes from the candidate nodes of the blockchain system, where the candidate nodes refer to nodes that have mortgaged their rights and interests in the blockchain system. [0003] In related technologies, a random number can be generated by the current round of consensus node...
