Problems solved by technology

[0002] In the construction of the structural framework of mobile games and applications, the central server occupies a very important position. It not only handles a large number of calculations, but also must store a large amount of game and application-related data. However, once the official server is attacked and cracked, the official data will be destroyed. Tampering will bring a devastating blow to the entire game and application network

example 1

[0039] Assuming that according to Mercator's law, we will divide the grade n=17, take the real longitude and latitude coordinates A, B, C three points, A (106.553027, 29.575564), B (106.55432, 29.575359), C (106.295878, 29.611985)

[0040] Calculated by the division formula:

[0041]

[0042] Customize the land number through the results of tileX and tileY (assuming that the result is "rounded" to define):

[0043]

[0044]

[0045] From this, it can be concluded that points A and B are divided into the same small virtual plot, while point C is divided into different lower virtual plots. ( figure 2 )

[0046] 3. The blockchain management method of small virtual plots:

[0047] 1. Based on tileX and tileY, round them up and make a custom number to make it a small rectangular virtual plot on the virtual surface, and store it in the "virtual title deed". Users can conduct point-to-point transmission, storage and recording of the small virtual land they hold through ...

[0097] Assume that because the block will be generated periodically, but the time for each node to record the block (original) is uncertain, so when it is recorded on the main chain, the recorded block may already have multiple branch chains, so when encountering When the node obtains the right to record blocks at the same time, the branch chain with the most blocks and the transaction content of the block will be truly recognized as "valid", and the shorter branch chain and the transaction content of the block will be directly recognized. Treat it as "unconfirmed" and wait for reconfirmation to prevent blockchain forks. ( Figure 7 ).

Abstract

The invention discloses a virtual parcel block chain data management method based on Mercator projection. The method comprises the steps of projecting an earth surface to a plane-coordinate system asrequired through a Mercator projection law, and dividing the projection into a plurality of rectangular small virtual parcels, and positioning the earth surface projection to the belonged small virtual parcel through any real latitude / longitude coordinate; the projection of the earth surface is managed by using the block chain, so that the centralization feature of the transaction data managementof the virtual parcel of the earth surface project is removed, and all nodes can possess effective accurate data and reach a consensus; even if the center server is subjected to the attack, the tampering and like devastating blow, the transaction data can be quickly retrieved; and the problem that the various data concurrency is increased since each node is connected with the server is greatly reduced.

Description

technical field [0001] The invention relates to a digital virtual surface management method. Background technique [0002] In the construction of the structural framework of mobile games and applications, the central server occupies a very important position. It not only handles a large number of calculations, but also must store a large amount of game and application-related data. However, once the official server is attacked and cracked, the official data will be destroyed. Tampering will bring a devastating blow to the entire game and application network. Contents of the invention [0003] The purpose of the present invention is to provide a virtual plot division and block chain data management method based on Mercator projection [0004] In order to achieve the above purpose, the following technical solutions are adopted: [0005] A method for managing virtual plot block chain data based on Mercator projection, characterized in that: the method includes projecting th...
