Problems solved by technology

The significance of the lottery itself is to attract traffic, strengthen publicity, and increase fun. If the fairness of the lottery itself is questioned, the results of the event often fail to meet expectations, and it is easy to cause adverse reactions. The result is not worth the candle
Therefore, there is a need to provide a fair, just and transparent activity management method to solve the trust crisis of Internet lottery activities

Embodiment 1

[0047] Please refer to figure 1 as well as figure 2 , this embodiment provides a method for managing lottery activities based on blockchain, which can ensure the fairness, justice and credibility of lottery results.

[0048] S1: At all lottery nodes ( figure 1 Two nodes are randomly selected from the lottery node 1, lottery node 2, lottery node 3 to lottery node n) to serve as the first production node and the second production node respectively. Obviously, corresponding to figure 1 The frame of composition, the lottery node 2 and the lottery node n are selected as the first production node and the second production node respectively.

[0049] This step is performed by the blockchain system to ensure the fairness of random selection. It can be simply understood that the lottery nodes are the people who participate in the lottery, and the first production node and the second production node are the lottery supervisors. Therefore, this step corresponds to randomly selectin...

Embodiment 2

[0076] This embodiment is further expanded on the basis of the first embodiment, and the fairness of the lottery result is improved by processing the initial lottery list.

[0077] In step S4 of Embodiment 1, after the second production node and the third production node receive the lottery information, they will generate the corresponding lottery list accordingly. Below, the process of obtaining the lottery list by the second production node will be described as an example. The third production node generates the corresponding lottery list in exactly the same way.

[0078] Specifically include:

[0079] First, the second production node generates an initial lottery draw list based on the information sending time recorded in all the lottery draw information received. That is to say, the initial lottery list is obtained by sorting the lottery identifiers corresponding to the lottery nodes in descending order or ascending order according to the information sending time.

[008...

Embodiment 3

[0088] This embodiment is further expanded on the basis of the second embodiment, which can realize multi-bet prize betting and increase the interest of the lottery drawing. That is, in a lottery event, support the lottery nodes to invest in multiple bets. Referring to the lottery’s winning mechanism, a person can purchase multiple bets of the same group of numbers to increase the probability of winning.

[0089] In this embodiment, the lottery information sent by each lottery node also includes the number of bets, and one bet corresponds to one lottery quota. For example, if you put in three bets, you can occupy three places in the lottery list.

[0090] In this embodiment, the processing of a currently received piece of lottery information by the second production node and the third production node is taken as an example for description. Can include:

[0091] The second production node and the third production node write a corresponding number of lottery identifications in ...

Abstract

The invention provides an activity management method based on a block chain. The method comprises the following steps that: a first production node and a second production node are selected randomly from lottery nodes; the first production node and a third production node receive lottery drawing mode selection information of a lottery drawing algorithm selected by the lottery drawing node at the same time, and determine corresponding lottery drawing modes respectively; the second production node and the third production node simultaneously receive lottery drawing information sent by the lottery drawing node and respectively generate corresponding lottery drawing lists; the first production node packages all lottery drawing mode selection information and lottery drawing modes into a first block through a first public key, and broadcasts the first block to the lottery drawing node; the second production node packages all the lottery drawing information and the lottery drawing list into a second block through a second public key, and broadcasts the second block to each lottery drawing node; and the third production node sends a lottery result and verification information to each lottery node. The method can ensure that the lottery drawing process is public, transparent, credible, searchable and supervised by the public, and the lottery drawing result has credibility.

Description

technical field [0001] The invention relates to the application field of block chains, in particular to an activity management method based on 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 blockchain is essentially a decentralized shared database. The data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance" . Since the data stored in each block in the blockchain is related to the data stored in the previous block, it is impossible to cheat by tampering with the data on the block, and it can ensure that the data on any block is open and transparent And cannot be tampered with. [0003] With the rapid development of Internet technology, the demand for Internet lottery business ...
