Embodiment Construction

[0021] The present invention will be further described below in conjunction with examples.

[0022] This embodiment provides a blockchain-based fair lottery lottery drawing method, comprising the following steps:

[0023] Step 1. Specify the lottery time. The lottery time for Shuangseqiu is 21:15 every Tuesday, Thursday, and Sunday. The lottery sales will be stopped at least one hour before the lottery. , after the notary staff seals up the sales data, and under their supervision, the lottery number is determined through the lottery device; when the lottery is drawn, 6 red ball numbers are drawn out first, and then 1 blue ball number is drawn out; the red ball number area is composed of 1-33 consists of a total of 33 numbers, and the blue ball number area consists of a total of 16 numbers from 1-16;

[0024] Step 2. Take the hash value of the latest confirmed block at the lottery time as input, and set the hash value of the latest confirmed block as of the lottery time to Bha...

Abstract

The invention discloses a blockchain-based fair lottery lottery drawing method, belonging to the technical field of data processing. The invention mainly includes the following steps: specifying the lottery time; performing six hash calculations to obtain the intermediate value; calculating the intermediate value to obtain six red ball numbers; performing one hash calculation to obtain the blue ball number. The present invention is based on blockchain technology and is completely transparent to consumers. Anyone can calculate the winning result according to the hash value of the block; based on blockchain technology, it is decentralized and does not require any investment in lottery equipment; The results are calculated based on unknown blocks, and are guaranteed by the computing power of Bitcoin. Any link participating in the lottery cannot cheat. Even the lottery issuer cannot predict or set the result of the lottery. The lottery lottery process is completely open, which is convenient for users to monitor ;The results of the lottery are completely randomized, and the probability of each number is the same, which avoids the disadvantages of physical equipment that cannot be exactly the same.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a blockchain-based fair lottery lottery drawing method. Background technique [0002] The blockchain consists of a group of nodes based on a point-to-point network. Each node maintains data consistency by implementing a consensus mechanism. The blockchain uses the hash value of the block to connect the data blocks to form a block chain structure, so that the data in the block has the characteristics of non-tampering, order preservation, and traceability. The blockchain generates, updates and stores data through a distributed node consensus algorithm, which can achieve the function of decentralization. The blockchain declares and transfers digital assets through digital signatures to ensure the security of data transmission and access. [0003] Bitcoin is a typical representative of blockchain. A Bitcoin block contains a block header and some Bitcoin transac...
