Abstract

The embodiment of the invention provides a method and apparatus for determining a random number in a blockchain, an electronic device, and a storage medium. The method includes the following steps that: whether a new action record is generated is detected regularly, wherein the action record is action information that is recorded when a user performs an action in the blockchain; if so, a random number seed is determined; and according to the random number seed, a random number corresponding to the new action record is determined. The electronic device detects whether a new action record is generated regularly and a phenomenon that the random number is determined immediately when the user performs the action is avoided; and thus because the regular detection cycle is unknown and can be changed, the determined random number result can not be predicted conveniently, so that the safety is improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, device, electronic equipment and storage medium for determining random numbers in block chains. Background technique [0002] In recent years, blockchain technology has risen rapidly. In transactions in blockchain and various decentralized applications based on blockchain technology, random numbers are an indispensable part, and random numbers directly affect the results of various operations. . The random number is generally determined according to the random number seed and the preset algorithm, so the random number seed determines the determined random number result. [0003] In the blockchain, after the user performs an operation, a random number will be determined immediately. The current way is to use the information of the current block as the random number seed. However, since the generation speed of blocks in the blockchain is fixed, the random ...
