Virtual Earth apk blockchain

Step 1: get the data file that stores the private key

we have two ways to get the data file that stores the private key:

the white paper on the security of encrypted digital currency wallet issued by cheetah mobile. On the one hand, it enables users to have a better understanding of the security problems of digital currency wallet and enhance their vigilance; On the other hand, the security standard of digital currency wallet is proposed to promote the security upgrade of similar procts in the instry and jointly protect the security of users' assets. We believe that both bitcoin wallet and Jaxx blockchain wallet proct teams can repair the vulnerability in a short time. However, because the private key has been exposed, users of these two procts should switch to other secure encrypted digital wallet applications immediately before the developer completes the vulnerability repair and upgrade, For example, cheetah Mobile released SafeWallet, and re created a new wallet address, through the transfer of assets from the old address to the new address, and finally void the old address. Only in this way can the security of digital assets be ensured

Just when everyone thought there would be no miracle, Google launched Google Earth, which shocked everyone. Not only because it has achieved such a grand goal, but also its browsing speed, efficiency and accuracy are highly praised. The whole earth has become a toy ball in Google's hands, which can be rotated and scaled at will. It's more like an intelligent globe. It only takes one second to reach the other side of the ocean to see the real world, and the previous illusions come true. Google has tens of thousands of servers every day for each update service of Google Earth client, and e to the large amount of data, distributed storage of data, and ensure that at least one backup server is on standby at any time in case of failure. According to reports, Google uses its own file operating system to make data storage, reading and processing more efficient. Google is the world's largest search service provider
Bill Gates provides MSN Virtual Earth services
corresponding to Google is Microsoft Virtual Earth, in addition to NASA world wind of NASA and sea of Tusheng company in China. As the oldest and largest software company, Microsoft is not only limited to software, but also involved in hardware and other aspects. Similarly, Microsoft also wants a share in the popular virtual earth. Bill Gates announced in 2005 to provide MSN Virtual Earth service:
satellite images with 45 degree building view
cover the block layer on the satellite image
it can overlay data layers, such as local business, restaurants and other geographical markers. In fact, they are basically the same as Google Earth's services. They also cut the data into regular small pieces, just like a square grid. It's only possible that the size of the grid may be different, and the accuracy and number of layers of different grid data are also different. On the one hand, they are affected by the data source, and on the other hand, they are under the pressure of the regional government. However, the difference is that Google provides its own browser client, Ms directly embeds vital earth into IE browser, which has many defects and restrictions. There is a big difference in efficiency between the two, and in a practical sense, Google Earth is more like a virtual earth, because it is dynamic, three-dimensional visualization, and practical to meet the requirements of users A virtual earth model similar to Google Earth is also provided in the Web Book developed by Microsoft, but the type and accuracy of its data can not meet the requirements at all, and the data is installed locally. One is the trouble of data dynamic update, and the other is the large amount of data, Recently, Microsoft also plans to combine virtual earth with local search. At present, it is only trial run in Seattle and San Franco of the United States.
Microsoft's virtual earth project includes real-time provision of local information, and its query results are expressed in geographic description language, Including maps and local real-time information. Microsoft Virtual Earth is committed to building a series of intelligent network services to make users more convenient and effective access to local information. Tusheng Virtual Earth searth is the first 3D simulated earth developed by a domestic company. Like Google Earth, you can see the earth we live on, suspended in the vast starry sky; You can play with the earth in your computer; You can use searth to browse any satellite map and electronic map all over the world; You can freely add your own tags and data on the earth to organize your enterprise's global 3D information system. Unlike Google Earth, you will be free to deploy your global and national 3D GIS applications without the restrictions of Google Earth
searth is essentially a 3D GIS development platform for the earth. Searth provides three-dimensional earth model and various roaming operation functions, as well as map browsing and geographic information calibration functions. Searth's solutions are as follows:
(1) popular 3D Earth Information System Applications
(2) internal 3D Earth Information System Application of large enterprises or cross regional business organizations
advantages of searth
(1) searth focuses on helping users quickly deploy global geographic information system applications. Simple and practical earth and map rendering engine and 3D geographic information system functions are important features of this proct
(2) automatic switching between satellite map and electronic map: when it is too close to the earth, the high-resolution satellite map information will interfere with the effective geographic data information. Searth provides automatic switch between electronic map and satellite map. Firstly, the satellite map is displayed. When approaching the earth to a certain height, the satellite map automatically switches to electronic map mode to help users focus on displaying and using GIS applications
(3) searth is a proct developed by Tusheng company from the bottom of digital earth display engine, so it has arbitrary customization function. With the development of searth, you don't have to worry about developing the earth API Application as a program plug-in
application scope
the application scope of searth can be divided into the following categories:
(1) develop a general three-dimensional earth information integration platform for the public, such as Google Earth, to build the Chinese people's own digital earth
(2) large enterprises or cross regional business organizations should build their own global or regional 3D GIS application platform
(3) using searth to build a distributed three-dimensional spatial information system of large-scale interpersonal community
