Problems solved by technology

The same principle is also used in the traditional lottery system. When the algorithm is known, test the random results of input parameters in advance, maybe just replace the order of a name participating in the lottery to hit the expected result. In the actual operation It is also executed according to the input parameters of this sort, so that the expected result of winning the lottery is obtained, and it is completely impossible to find that there is cheating in the middle

Abstract

The embodiment of the invention provides a data processing method, blockchain node equipment, electronic equipment and a computer program, whichrelate to the field of blockchains. The method comprisesthe steps that an encryption value generated by at least one notarization party terminal is acquired, and the encryption value is linked; after the encryption value is linked, user information of atleast one candidate user is obtained, and the user information of the at least one candidate user is linked; after the user information is linked, a random number generated by at least one notarization party terminal is obtained, and the random number is linked; a random number seed is obtained according to the random number on the blockchain, the encryption value and the user information of the candidate user; and according to the random number seed, user information of the target user is obtained through a preset random algorithm in the smart contract. According to the embodiment of the invention, the possibility that the random number seeds are not predicted in advance is realized, and the reliability of screening the target users is ensured.

Description

technical field [0001] The present application relates to the technical field of block chain, specifically, the present application relates to a data processing method, block chain node equipment, electronic equipment and computer programs. Background technique [0002] When it comes to resource allocation, lottery is a common technical means, such as license plate lottery, new real estate lottery and so on. In the traditional lottery mode, in order to ensure fairness, notarization and openness, on-site lottery, notary lottery or random lottery may be used to provide the public with credible lottery. [0003] The current random algorithms are actually pseudo-random, that is to say, as long as the seeds of the random algorithm (that is, the input parameters of the program) are the same, the results must be the same, so some hackers can control the input parameters to achieve A random result hits its intended target result. The same principle is also used in the traditional ...
