Problems solved by technology

The development of the Internet has made people more and more dependent on the centralized system for the use of random numbers. However, most of the centralized systems generate pseudo-random numbers, and there is a risk of cheating. For example, in quiz applications, When there is a huge interest temptation, the centralized system may cheat and benefit from it

Abstract

The embodiment of the invention provides a random number generation method and device based on a block chain. The method comprises the following steps: receiving a seed display value issued to the block chain by each participant of an event in a first time period after the event occurs; wherein the seed display value is a value obtained by operating a seed selected by the participant through an encryption algorithm; receiving seeds issued to the block chain by each participant of the event in a second time period after the event occurs; respectively detecting whether seeds corresponding to seed display values published by each participant of the event in the first time period are consistent with seeds published in the second time period or not through the encryption algorithm, so as to verify each participant of the event; and calculating seeds published by all verified participants of the event in the second time period by using a random algorithm to obtain a random number. Through the embodiment of the invention, the fairness of the generated random number can be ensured.

Description

technical field [0001] The present invention belongs to the technical field of blockchain, and in particular relates to a random number generation method, device, terminal equipment and computer-readable medium based on blockchain. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is essentially a decentralized database, which is a series of data blocks associated with cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting ) and generate the next block. In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain tec...
