1. The proction of virtual currency needs a professional team, but if you make a direct currency, there is no wallet, there is no maintenance, and it's just a pure number, it's much simpler, the cost is very low, and a trading platform is thousands of yuan. However, there are serious loopholes in this platform and it is easy to be attacked
if you want to create a virtual currency like bitcoin, Ruitai coin and Qianjin card, you need to make some efforts. First of all, these coins need card method and a downloadable wallet. The application scenarios of this kind of currency have been determined. At the same time, you need to create a secure and reliable trading platform.
2. Mine pool register an account, create a miner set password, download a cgminr run OK
3. The n-card with strong general computing performance of AMD graphics card stands by the side
the mainstream is hd7970 hd7950 hd7850 hd7990 r9-290x R9 280x
the other worst configuration can be used to mine is multi card (a-card) crossfire
4. The computing power of home PC is too low, and the money earned in a month is not enough for electricity charges, so mining machines are needed
mining is a technical activity, which tests the performance of CPU and GPU. Now on the market, the machine specially optimized for the calculation algorithm of the generation of bitcoin is the miner. At present, it takes about 16000 to buy a state-of-the-art S9 miner on 58btc. There are also special management services, which can save all kinds of troubles. If the owner wants to buy a miner on a certain treasure and do it by himself, he is advised not to dig. You know the reason.
5.

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

6. It's impossible to mine with an ordinary computer<

robots or excavators equipped with computers and related programs can use different tools according to different geological environments.
such intelligent equipment system can mine.
7.

Preparation for Mining:

Step 1: you need a pick ~

pick types are: Wood pick, stone pick, iron pick, gold pick, diamond pick

efficiency comparison: Gold pick (limited excavation! Mining in hell works wonders. Mining is the fastest!)& gt; Diamond pick & gt; Pick & gt; Stone pick & gt; Wood pick

rability comparison: diamond pick & gt; Pick & gt; Stone pick & gt; Wooden pick & gt; Golden pick

damage comparison: diamond pick 5 & gt; Pick 4 & gt; Stone pick 3 & gt; The attack speed of wooden pick / golden pick 2 is 1.2

(recommended by novices): for the first mining, because wooden pick is used, you can dig 11 stones first, then make a furnace, and then make a stone pick. You can throw the wooden pick into the furnace, burn an iron ingot, and then throw it away. If you are particularly economical! Then use it up!)

Step 2: you need to know what you are going to dig! What pick can be used?

coal is the only mineral that wood pick can dig, and coal is the only mineral that gold pick can dig. Coal, iron ingot and Lapis Lazuli are the minerals that stone pick can dig. Coal, iron ingot, gold ingot, lapis lazuli, ruby, emerald and diamond are the minerals that iron pick can dig. Coal, iron ingot, gold ingot, lapis lazuli, ruby, emerald and diamond are the minerals that diamond pick can dig Diamonds Diamond pick can also dig a hard block, which can make Obsidian of hell gate)

additional knowledge: construction method of hell gate (standing on the ground): first, build a Obsidian with height of 5 and width of 4

and then use a flint to make a fire on the two obsidians under the middle hole. Congratulations on your journey to the lower world of hell. Of course, if you want to save materials, it's OK Wool is used to identify height and width)

2! There may be a lot of minerals exposed. There is a very small chance of the following. Of course, there are good things in the box. The biggest danger of abandoned mines is

cave spider! But the cage can be raised later! If torches are inserted around, spiders will not be generated

because monsters can no longer be born, what torches inserted in the brush cage will seal that the brush cage is fake

3 the underground Canyon

can also be seen, but it's OK to pass by and see what you don't want. Of course, there may be magma pool

4. Dungeon

ngeon will have boxes and brush strange cage, lucky box two, bad luck may not have a box! If you're lucky, you can see the sand sinking in the desert, and the ngeon is below. The principle of the brush monster cage is the same. It can brush monsters in the dark. Generally, the brush monster cage is divided into zombies, spiders and skeletons. If you want to do it, you can make a simple brush monster tower. If you don't know how to do it, I will send a tutorial in the future. You can also search other people's ~

5, It will fly to the direction of the fortress ~

it's better to try its principle in an open place! The eye of the shadow flies into the air, and it has a chance to fall down or break up in the air. The fortress is the enemy who can go to the land of the shadow, that is, the enemy who can fight the shadow dragon. This fortress is a lot of good things! There are boxes everywhere, but it's very easy to get lost! Lu Chi pays special attention to finding someone who is not Lu Chi to carry or make some small marks

and my favorite library. Generally, there are 1-2 libraries in a fortress. There is no shortage of books! Gather 12 eyes of the final shadow and you can go to fight the dragon. Are you excited

Luo Ji: generally 20 eyes of the last shadow can find a fortress! There are only four fortresses in one world! You heard me right! If you are playing with the server, you can go back to the main city and use the eye of the final shadow first. How do I find the fortress!? With a final eye. And run in that direction! You think it's long enough, you can use another one! If you go back, run back half

and then use it again. If you don't, keep running in that direction! Do you find that it no longer flies to the sky, but falls to the ground? Congratulations. Dig down. The fortress is below

8. First make an assembly rod, then right-click the mining machine with the assembly rod, and he will build it automatically, provided the backpack has materials
9. Major introction: Capital Normal University is one of the earliest universities in China to offer undergraate major of e-commerce. This major aims to cultivate compound high-quality talents who can skillfully use the basic theories of management and economics, master computer and big data related technology, e-commerce professional knowledge and skills, and have pioneering and innovative spirit and practical innovation ability. The teaching and research team has the characteristics of high ecation background, rich experience and internationalization. At present, the professional "progressive" e-commerce talent training mode under the background of big data "has been mature and applied, and the teaching achievement won the first prize of Beijing Higher Ecation Teaching Achievement Award in 2018. Professional infrastructure construction is complete, with advanced e-commerce and big data teaching and research experimental center. There are various professional training modes to improve students' professional quality and practical ability through practice teaching, subject competition, subject research, lectures and social practice
core courses: e-commerce logistics management, e-commerce system analysis and design, network marketing, data analysis and mining, mobile Internet application development, business and economic statistics, multimedia technology and application, website design and practice, principles of management, management information system, principles of accounting, consumer behavior, principles of economics, etc
professional features: facing the needs of the rapid development of national economy and Society for e-commerce talents, under the background of big data era, e-commerce curriculum group and hierarchical practice teaching system are constructed. Combining practice teaching, scientific research projects and subject competitions, we can promote subject research by practice teaching, and then improve the performance of subject competitions, so as to effectively improve students' practical innovation ability. The mobile Internet, business intelligence, blockchain and other new technologies are integrated into the curriculum construction and teaching practice to cultivate e-commerce talents with big data technology skills
employment direction: graates are widely employed in well-known e-commerce enterprise platforms, Internet enterprises and institutions, such as Jingdong group, Internet company, Amazon company, China Unicom, instrial and Commercial Bank of China, etc. Many graates serve various types of e-commerce enterprises in the capital, and take important positions to grow into responsible persons or business backbones. Graates can apply for master's degree in economics, management, information technology and other fields of well-known universities at home and abroad. Among the graates of the last three years, more than 30% of them went to higher ecation in China and studied abroad.
10. First of all, this paper summarizes the causes of such problems as "application failed to start e to incorrect application configuration":
after Windows XP SP2, windows introced the concept of side by side execution, which was originally proposed by. Net, but later windows integrated this concept into the operating system. We should all know the problem of DLL hell. In order to solve the problem of DLL hell, side by side proposes that different versions of DLL files can exist in the same system at the same time, and applications that depend on different versions of DLL can use the originally compiled DLL when they run. For example:
1. Suppose you write a C + + program a, which uses MFC 8.0 (this version is released with Visual Studio 2005)
2. Later, the machine upgraded the version of visual studio, and the MFC library upgraded from 2005 to 2008 was version 9.0. At this time, two versions of MFC, 8.0 and 9.0, were installed in the operating system
3. Write another C + + program B with Visual Studio 2008, which depends on MFC 9.0
4. If you run program a, the operating system will load MFC 8.0 into the process of A
5. If program B is running at the same time, the operating system will load MFC 9.0 into the process of B. This is the concept of side by side execution
the reason why the operating system can do this is that before loading programs a and B, it will view the manifest files of a and B in addition to the DLL information that a and B depend on in PE format. The manifest file stores the environment setting information of windows executable files (including exe and DLL files) to run. The file name is usually the full name of the executable file plus. Manifest. For example, the manifest file of notepad.exe should be notepad.exe.manifest. In addition, some programs embed the manifest file directly into the resources of the executable file, which is why sometimes you can't see the manifest file of the program. Generally speaking, the content of a manifest file is as follows:

& lt;? xml version=' 1.0' encoding=' UTF-8' standalone=' yes'?& gt;< br />< assembly xmlns=' urn:schemas-microsoft-com :asm.v1' manifestVersion=' 1.0'& gt;< br />< trustInfo xmlns=" urn:schemas-microsoft-com :asm.v3"& gt;< br />< security>< br />< requestedPrivileges>< br />< requestedExecutionLevel level=' asInvoker' uiAccess=' false' /& gt;< br /></ requestedPrivileges>< br /></ security>< br /></ trustInfo>< br />< dependency>< br />< dependentAssembly>< br />< assemblyIdentity type=' win32' name=' Microsoft.VC90.DebugCRT' version=' 9.0.21022.8'< br />processorArchitecture=' x86' publicKeyToken=' 1fc8b3b9a1e18e3b' /& gt;< br /></ dependentAssembly>< br /></ dependency>< br /></ assembly>

in the above example, it shows that this program depends on CRT 9.0 and is a debug version. The CPU architecture is a 32-bit CPU. For programs that embed manifest files into resource files, there is also a way to see manifest information
1. One is to use mt.exe (manifest handler of Visual Studio):
MT - input tresource:test.exe;# 1 / out:test.manifest
2. Another method is to use mpbin program to print the contents of the entire exe to a file, then open it with a text editor, and search assem string style to find the manifest information
