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

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.
