Embodiment Construction
[0027] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.
[0028] figure 1 It is a schematic diagram of a lottery scene in an embodiment of the present invention. Such as figure 1 As shown, in this embodiment, every time the accounting node generates a block, it will generate N second random numbers sorted, and broadcast N second random numbers to the blockchain...

The invention designs a drawing method. The drawing method comprises the steps of: freezing a certain amount of assets at first, so that the qualification of obtaining first random numbers, the numberof which corresponds to the number of the assets, is obtained; secondly, generating seed information according to several second random numbers of previous N blocks, wherein N is a positive integer;generating the first random numbers according to the seed information; then, judging whether a current node is selected as a consensus committee member or not according to the held first random numbers and a pre-configured difficulty value; and finally, broadcasting the held first random numbers, furthermore, receiving the first random numbers broadcasted by other nodes, and, after sorting the held first random numbers and the first random numbers broadcasted by other nodes, dividing consensus committee members corresponding to various first random numbers in the sorting result into accountingnodes and consensus nodes according to a pre-configured rule. Thereby, when consensus in each round is carried out, the consensus committee members are composed of different nodes; and thus, the problem that benefits of other nodes are damaged due to the fact that the consensus committee members plot together for obtaining the benefits can be solved.
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 ...
