Short time mining
how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.
Mining is the use of bitcoin mining machine, which is used to earn bitcoin
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
< H2 > extended data:
bitcoin mining process:
1. To find the ore pool
to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm
2. Download bitcoin miner (software)
in fact, there are many kinds of this miner, you can go to the official website to download
3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before
4, bitcoin mining start
when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver
"Transaction is mining" is a typical platform operation mode. Users mine through transactions. Some platforms will issue their own tokens as rewards for users' trading behavior
Relevant introction:in June 2018, the cryptocurrency exchange fcoin put forward the concept of "trading is mining", and in a short period of time, the daily trading volume rose to the first in the world, triggering a war between exchanges
"transaction is mining" is actually a return mechanism of personal transaction fees based on platform currency. Strictly speaking, there were similar playing methods before the establishment of fcoin. For example, bibox had a mechanism to return a certain proportion of fee income to platform currency holders
extended data
fcoin's "transaction is mining" is repackaged. Following the allocation rules of bitcoin mining, 51% of platform currency ft is taken as the mining reward pool. Through "mining (trading on fcoin)", FT is graally unlocked. Once 51% of FT is fully fed back, "mining" is automatically terminated
in terms of specific implementation, fcoin trading means mining starts at 0 o'clock every day (GMT + 8), and the transaction fees generated by users will be converted into ft for accumulation every hour. The conversion price is calculated according to the average price of FT in that hour (the average price is calculated as total transaction amount / total trading volume)
2. Look at programming in Objective-C 2.0, not Objective-C 2.0 programming
3. Watch cocoa design patterns and cocoa programming developer; Don't ignore them just because they are difficult and we are beginners
4. Yes, you need a Mac if you really want to learn Objective-C and cocoa
5. Don't let go of any small programming problems that seem very simple - they are often not so simple, or can lead to a lot of knowledge points
6. Being able to use Objective-C doesn't mean that you can program with cocoa
7. It's not difficult to learn grammar, and so is foundation, AppKit, UIKit, core data and core animation
8. Please always remember that to write a good app, interface design and program functions are equally important - in fact, you can always remember that MAC / IOS user interface protocol is also a must read document
9. You can't learn Objective-C well without reading C language books
10. It's easy for impetuous people to say: XX language can't work, you should learn YY—— You can't do it yourself
11. Impetuous people are easy to ask: what should I learn—— Don't ask, just learn
12. Impetuous people are easy to ask: is XX rich—— I suggest you rob the bank
13. It's easy for impetuous people to say: I want the Chinese version! I can't speak English—— no way? Learn
14. Impetuous people are easy to ask: which is better, XX or YY—— Let me tell you, all right - as long as you learn
15. There are two kinds of impetuous people: a) people who just wait and see but don't learn; b) People who only study but don't insist
16. Cocoa is the framework of Objective-C, mainly including foundation, AppKit and core data. Cocoa touch is the IOS version of cocoa, mainly including foundation, UIKit and core data
17. Objective-C not only adds a class for C, but also the runtime environment
18. One of the best ways to learn programming is to read the document and source code. Please make good use of the source code of the program instance in the Xcode document
19. Remember, Objective-C is a dynamic language
20. Please read Objective-C 2.0 programming language and other documents - official documents are always the most authoritative and complete reference books
21. If you can understand the book, please read it carefully; If you don't understand a book, please read it
22. Don't expect to remember and master anything by reading the first time - please read the second and third time
23. Please remember that IOS and MAC development are essentially the same, but the differences should also be paid attention to
24. Don't stay at the Xcode level. Mastering the use of GCC, GDB, GIT and other tools through the command line will double your efficiency
25. Discuss meaningful knowledge about Objective-C and cocoa with others, instead of arguing about whether cocoa is OK or whether Objective-C is better than C + +
26. Don't be confused by "technology" terms such as core XXX, which are just the frameworks (Libraries) of C and Objective-C
27. If you have learned C + +, please forget to use. (DOT) call method. Objective-C uses square brackets, and the more accurate name is "message passing"
28. Objective-C is a strict superset of C language, which is closely related to C language. C language is a part of Objective-C
29. Please don't think that there is no problem in learning Objective-C after learning C + + - you are just learning a brand new language
30; I will decide whether I have learned Objective-C in the future< The secret of learning programming is: programming, programming, reprogramming
32. Please pay attention to the following books: cocoa programming developer & 39; s HandbookCocoa Design PatterniOS 4 Advaced ProgrammingCocoa Programming A Quick-Start Guide for Developers
33. Don't forget open source just because Apple is a commercial company. Personally, open source is giving, but you get more. Don't forget, apple itself uses a lot of open source technology
34. Please input the program examples in the book to the computer for practice, even if the source code is in the CD-ROM
35. In your spare time, you can turn your idea into code and put it on GitHub, or turn it into a software in the app store
36. Please pay attention to Objective-C runtime environment programming and apply it to your own programs
37. Review the programs you have written before and try to rewrite them to apply the new knowledge you have learned
38. Don't miss any of the exercises in the book - please finish them all and write down your ideas for solving them
39. Objective-C, cocoa and Xcode should learn and master the integrated development environment at the same time
40. Since you have decided to learn Objective-C, please keep learning, because the purpose of learning programming language is to master programming technology, which is cross language
41. If you want to do a good job, you must first sharpen your tools. To develop Objective-C and cocoa well, please make good use of Xcode
42. Please don't stop when you find that your method is poor in the middle of writing cocoa program; Please finish the rest as soon as possible to ensure the integrity of the design, and then analyze your own mistakes and redesign and write (see 43)
43. Don't worry, it's not easy to design Objective-C classes; The class in our program and our class design level are improved and developed in the continuous programming practice
44. Never follow some rules you are not familiar with just because the program is "small" -- good habits are cultivated, not memorized at once
45. When you learn a difficult point of Objective-C, try to explain it to others and let them understand it
46. Record the knowledge points you find you ignore or don't understand when communicating with others
47. Please constantly put forward higher requirements for your own programs, even if your program version number will become version 100.xx
48. Save all the programs you've written - GitHub is your best code hosting tool
49. Please don't be impetuous
50. Please love Objective-C!
