Abstract

The present invention designs a lottery method. First, a certain amount of assets is frozen to obtain the qualification of a random number corresponding to the amount of assets; secondly, a random number is generated according to the public information of the previous block; and then according to the held random number and the pre-configured difficulty value to judge whether the current node is selected as a member of the consensus committee; finally, broadcast the random number held by other nodes, and receive the random number broadcast by other nodes, and compare the random number held with the random number broadcast by other nodes After sorting, according to the pre-configured rules, the members of the consensus committee corresponding to each random number in the sorting result are divided into bookkeeping nodes and consensus nodes, so that in each round of consensus, the members of the consensus committee are composed of different nodes. Solved the problem that members of the consensus committee colluded to gain benefits and harmed the interests of other nodes.

Description

technical field [0001] The invention relates to the technical field of blockchain, and relates to a lottery method, a consensus method, equipment and a storage medium. Background technique [0002] In the existing blockchain network, due to the large number of nodes, each block can only package less transaction information. In order to improve the performance of the number of packaged transactions per second in the blockchain network, the existing solution is to select a fixed number of super nodes with strong credibility to form a consensus committee. As a member of the consensus committee, the super node conducts consensus on transaction information, generates blocks and other operations. Since supernodes are fixed, theoretically, no one can guarantee that supernodes will not collude for profit and harm the interests of other nodes. [0003] To sum up, it is currently necessary to provide a method that can successfully prevent the members of the consensus committee from ...
