Abstract

One or more embodiments of the present specification provide a block chain based random object selection method and apparatus, The method comprises: receiving a plurality of selected object nodes publishing a selected transaction to a distributed database of the block chain in a first period of time, the selected transaction being generated based on an object reference number determined by the selected object nodes; and receiving a selected transaction from a plurality of selected object nodes. According to the preset calculation rules, calculating values corresponding to a plurality of selected object nodes based on the eigenvalues of the specified events and the object reference numbers corresponding to the selected transactions, wherein an eigenvalue of the specified event is a eigenvalue calculated for a specified event occurring after the first period according to a preset mapping algorithm, the eigenvalue of the specified event being unpredictable before the specified event occurs; According to the preset selection rule, the selected object nodes are selected based on the values corresponding to the plurality of selected object nodes.

Description

technical field [0001] This specification relates to the technical field of data processing, and in particular to a method and device for selecting random objects based on blockchain. Background technique [0002] Random object selection is often used in computer random allocation of resources, random assignment of tasks, or any other required business scenarios. The random object selection method based on a computer or server is difficult to ensure the fairness and verifiability of the random selection process, because a The selection methods implemented by computers or servers are extremely easy to be manipulated by humans, and it is difficult to achieve true "random" selection, and it is difficult for the outside world to monitor and verify whether the selection methods implemented by them are not manipulated during and after the event. Contents of the invention [0003] In view of this, one or more embodiments of this specification provide a block chain-based random ob...
