Problems solved by technology

[0005] The previous random number generation process cannot allow the operator of the process to effectively prove to the random number user that the process is not manipulated, so even if the generation process applies a physical-level random source, the generated random number is passed to the It cannot be recognized as a credible random number when the user

Embodiment Construction

[0009] Use the random number that can be generated in the latest block (or the latest few blocks) information of other blockchain systems (such as the Bitcoin system) as the random source. If there are multiple random sources, run a transparent and public first A deterministic algorithm is used to synthesize a source of randomness.

[0010] Using the aforementioned random source as input, a selection algorithm is applied to pick out the initial set of random number producers from all nodes.

[0011] Each random number producer generates a random number seed, which may be manually participated or automatically generated by node computing equipment. The hash value of the generated random number seed is notified to other blockchain network nodes, among which Attach signature information to prove that it is indeed the information released by the selected random number producer. When the preset random number time interval threshold has passed, all producers who have notified the h...

Abstract

The invention discloses a method for generating trusted random numbers by applying block chains. According to the method, a number, with certain randomness, generated by another block chain system canbe taken as input, or a random number generated in the last round can be taken as the input; a set of random number generators is selected from all the nodes of a block chain through a transparent and open certainty algorithm; the generators respectively generate respective random number seeds; all the random number seeds are used, or the random number input is used with the random number seeds to serve as parameters; and a new trusted random number is generated by applying the transparent and open certainty algorithm.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and a related device for generating credible random numbers using block chains. 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. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. [0003] Using the consensus mechanism, non-trusting subjects can cooperate in a transparent and credible way to complete some tasks that originally required mutual trust. [0004] Credible random number generation refers to the generation of random numbers in a transparent and credible way, and the subjects involved in the generation process cannot cheat to make the final random numbers have the non-random characteristi...
