Abstract

The invention designs a draw method. The draw method comprises the following steps: firstly, freezing a certain number of assets to obtain the qualification of first random numbers in a quantity corresponding to the assets; secondly, when a node becomes an accounting node of a current block, generating seed information according to a plurality of second random numbers held by the accounting nodesof previous N blocks and second random numbers held by a plurality of current nodes; thirdly, generating first random numbers according to the seed information; fourthly, judging whether the current nodes are selected as consensus committee members or not according to the first random numbers held and a pre-configured difficulty value; and finally, broadcasting the first random numbers held, receiving the first random numbers broadcast by other nodes, sorting the first random numbers held and the first random numbers broadcast by the other nodes, and dividing the consensus committee members corresponding to the first random numbers in a sorting result into accounting nodes and consensus nodes according to a preconfigured rule. Through adoption of the draw method, the consensus committee members all consist of different nodes in each round of consensus, thereby solving the problem that the consensus committee members collude to gain benefits but 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 ...
