How to shield the ore pool

1.

After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites

in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution

as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners

extended data:

handling charge:

bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)

because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction

at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress

however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain

in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

2. It's not so easy to close. I used to use the fish pond all the time, but the fish pond didn't welcome me as a small miner. Later, I turned to ha Yu miner, and the calculation power of the mine pond was not low
the biggest advantage of using hayu mining pool is that as long as you connect to the mining pool, you can use the mobile app to monitor the mining machine, withdraw cash every day, and the number of users has been increasing, and there are online customer services to answer any questions you have!

3. The difficulty of bitcoin block is abnormal. Let's forget it. It's impossible to mine without connecting to the mine pool

5. How to choose mine pool

ore pool cost

at present, the allocation modes of ore pool mainly include PPS, PPS +, FPPS, PPLNs and solo mode

in the corresponding allocation method, the mine pool charges part of the income of the miners at a certain rate as the mine pool fee

PPS: the income is stable. As long as the mining machine works normally, there will be income. The income is related to the submitted workload, and has nothing to do with the lucky value of the ore pool and the transaction fee

PPS + (pay per share plus) settlement method is an improvement on the traditional PPS settlement method. Based on the traditional PPS settlement method, the distribution of miners' fees is increased

FPPS: full PPS, which allocates all block income including transaction fees. Compared with the traditional PPS settlement mode (no transaction fee allocation), it can increase the income by 10% - 20%

under the PPLNs (pay per last n shares) settlement mode, every effective block found in the ore pool is allocated according to the proportion of user computing power in the pool computing power in the past n difficulty cycles. In this way, the income of miners is related to the output of ore pool. The income of miners is unstable, but the long-term average income is higher

in solo settlement mode, all the income is distributed to the miners who dig out the block, and other miners do not participate in the distribution. The mine pool charges very little handling charge, which is used for the operation and maintenance of the mine pool< How to choose a mine pool:

1< Secondly, choose your distribution mode, pursue stability or high income. It is generally recommended to choose PPS or PPLNs of large ore pool< Finally, according to the distribution mode, select the supported ore pool, and choose the one with fast connection speed and good income

4. In addition, 1-2 spare ore pools are selected for emergency use.

7. The timeout of the Ping pool request indicates that the link to the pool may be blocked or closed. You may choose to try it through an agent or other pools. Now that the country has begun to control bitcoin, there is no money left for mining.

8. Babbitt has a post: using bitcoin and eloipool (supporting stratum) to set up bitcoin mine pool. Eloipool is a mine pool server program based on Python 3 (supporting stratum)

9. Verify that the server computer has a working network connection. First, use the basic network and hardware troubleshooting steps to check whether the relevant client hardware (cables and network adapters) is working properly on the client

if the server hardware is ready and working properly, use the ping command to check the network connectivity between other in use and available computers or routers (such as its default gateway) on the same network as the affected DNS server

many users like to use two screens, especially programmers, game players, video procers and so on. It can be said that the two screens display and the game work together. So what's the use of setting up al screen display or multi screen display? How to set up al or multi screen display? Here is a brief introction to its function and specific operation method

What are the advantages of al screen display (computer)

1. Large screen splicing

(splicing computer graphics, splicing dynamic video) projection wall; Command and dispatch systems for public security, military, railway, transportation, aerospace, posts and telecommunications, satellite launching, etc; Graphics and image editing, 3D animation, multimedia design; Process control in instrial field; Information display of securities trading, futures and banks; CAD / CAM design, typesetting editing system, video image editing

2. File editing:

when making planning documents, you should also refer to and search for relevant network information, so as to avoid data confusion caused by switching windows

3. Drawing editing:

when using the drawing software to design a case, the reference document window can be opened at the same time, and the desktop can also be extended to facilitate the processing of large-scale design draft proction, which does not overlap with the proofreading window

4. Film and television entertainment:

(1) watch Internet TV and browse the program introction of other channels at the same time, so that you can not miss the wonderful programs

(2) when playing online games, you can synchronously compare the secret skills of the game strategy< 5. Office:

(1) view large tables (such as Excel charts) across more than two screens

(2) to open multiple programs on the extended desktop space at the same time, there is no need to switch the windows frequently

(3) read the email and open the attachment file on other screens at the same time

6. Program design:

when writing a complex program, another window can view the program execution result screen at the same time to facilitate updating and modification

these are the advantages of al screen computers. Do you know something about al screen computers now? See small make up for everybody to enumerate is the advantage of double screen computer is a little bit excited? Let's take a look at how to set it<

1. Hardware requirements (take win10 system as an example)

1. The computer host must have any two-way output independent graphics interface of VGA / DVI / HDMI (generally supported by entry-level graphics card), as shown in the figure below:

2. Prepare any two VGA / DVI / HDMI cables, and the appearance diagram of the corresponding connection cable of the display output interface is as follows:

3. Two monitors, Support any two interfaces of VGA / DVI / HDMI (otherwise VGA converter connector is needed)
