Problems solved by technology

Although these activities will announce some lottery / sorting rules in advance, because the event organizer is a centralized operation and maintenance platform, it will invest huge manpower and material resources. On the other hand, its fairness is difficult to guarantee. Organizations or individuals will engage in fraud and self-stealing during the entire activity, and third-party hackers also covet the benefits of these resources, invade the system platform, destroy and modify the lottery / sorting rules

Embodiment Construction

[0025] In order to make the objects, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clear and complete, and it is apparent that the described embodiments are part of the embodiments of the present invention, rather than All embodiments; Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention without all other embodiments obtained by creative labor.

[0026] Since the technical species of the block chain is more, some important details are described in order to facilitate understanding of the implementation of the present invention.

[0027] In the block chain network, the data is permanently recorded in the form of a file, called block. Once the new block is on the chain, you can no longer change or delete. Each block records all events that occur for a period of time it is created. The parameter infor...

Abstract

The invention relates to the technical field of block chains, and provides a drawing / sorting method based on a block chain technology. The method comprises the steps of specifying the block height ofa public chain in advance to determine each block generating a drawing / sorting result, and calculating a drawing / sorting number by using a random number in the head of the drawing / sorting block. The method is suitable for various situations taking a digital number as the drawing / sorting result. Based on the recording disclosure and tamper-proofing characteristics of the block chain technology, themethod provided by the invention cannot enable the random number in the block to be equal to one or some specific values in advance, and cannot predict or set the lottery drawing / sorting result in advance, so that the possibility of lottery drawing / sorting cheating is eliminated technically.

Description

Technical field [0001] The present invention relates to the field of block chains, and more particularly to a lottery / sorting method based on block chain techniques. Background technique [0002] In modern society, limited resources are ordered, effective, fairly, and is a topic that is related to everyone's personal interests. Among them, lottery and sorting (queuing) are two common methods in the process of resource allocation, and there is a lot in real life.
