The present invention designs a lottery method. First, a certain amount of assets is frozen to obtain the qualification of the first random number corresponding to the amount of assets; secondly, seed information is generated according to a number of second random numbers of the first N blocks, wherein, N is a positive integer; then generate the first random number according to the seed information; then judge whether the current node is selected as a member of the consensus committee according to the held first random number and the pre-configured difficulty value; finally, broadcast the held first random number A random number, and receive the first random number broadcast by other nodes, after sorting the first random number held by the held first random number and the first random number broadcast by other nodes, according to the pre-configured rules, each first random number in the sorting result The corresponding consensus committee members are divided into bookkeeping nodes and consensus nodes, so that each round of consensus, the consensus committee members are composed of different nodes, which solves the problem that the consensus committee members collude to obtain benefits and harm the interests of other nodes The problem.
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 ...
