The present invention designs a lottery method. Firstly, a certain amount of assets is frozen to obtain the qualification of the first random number corresponding to the amount of assets; secondly, when becoming the accounting node of the current block, according to the Some second random numbers held by the bookkeeping node and some second random numbers held by the current node generate seed information; then generate the first random number according to the seed information; then according to the first random number held and the predetermined The configured difficulty value judges whether the current node is selected as a member of the consensus committee; finally, it broadcasts the first random number it holds, and receives the first random number broadcast by other nodes, and compares the first random number it holds with other nodes After the broadcasted first random numbers are sorted, according to the pre-configured rules, the members of the consensus committee corresponding to the first random numbers in the sorting results are divided into bookkeeping nodes and consensus nodes, so that in each round of consensus, the members of the consensus committee It is composed of different nodes, which solves the problem that members of the consensus committee collude in order to obtain benefits and harm 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 ...
