Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] figure 1 It shows that an embodiment of the present invention provides a lottery method based on the Ethereum block chain, including:

[0029] S11. Set a preset lottery program on the Ethereum blockchain;

[0030] S12. When the lottery program is executed in the Ethereum, the input list of objects to be drawn, lottery conditions and lottery seed are received, and the lottery seed is the hash value of the latest block;

[0031] S13. Execute a lottery program according to the list of objects to be drawn, lottery conditions and lottery seeds, obtain and display a lottery result.

[0032] With regard to the above step S11-step S13, it should be noted that in the embo...

Abstract

The invention provides a method and a device for drawing lots based on an Ethereum block chain. The method comprises the following steps: setting a preset drawing procedure on the Ethereum block chain, and receiving input drawn object list and drawing conditions when the drawing procedure is performed on the Ethereum block chain, performing the drawing procedure by taking the Hash value of the newest block as a drawing seed, and acquiring and displaying drawing results. The open drawing procedure can be realized, the drawing is performed on the Ethereum block chain, and the Hash value of the newest block on the Ethereum block chain is taken as a drawing random number, so that the fairness of the random number is guaranteed.

Description

technical field [0001] The present invention relates to the field of ethernet application technology, in particular to a lottery method and device based on the ethereum block chain. Background technique [0002] Lottery plays an important role in daily life and some systems, such as welfare lottery, license plate lottery, public rental housing lottery, and self-housing lottery. There are generally two types of current lottery systems: physical and software. Large-scale lottery systems are generally software systems, and software lottery systems are generally centralized lottery systems. Most systems are a black box for users participating in the lottery, and the fairness of the program needs to rely heavily on Opaque system design. In order to improve fairness, software systems may generate random numbers with the help of physical equipment, such as two-color balls, and broadcast live when generating random numbers. [0003] However, ensuring that the random seed of the l...
