Mine pool network setting

1.

Mine pool refers to:

as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network

after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"

extended data:

the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in

but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:

the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network

2.

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

3. Because indivial mining is difficult to meet the demand, the global computing power is increasing, and it is difficult for a single device or a small amount of computing power to dig bitcoin again. It is also a combination of a large number of mining machines to form a mine pool. The computing power of the mine pool is very powerful, and it can also ensure that virtual currency can be g more quickly. So how can the mine pool dig? Let's have a look
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.

4. It's one of the baskets with BTC;

5. The relationship between network speed and router is still very big
if your wireless network or network speed through router can not reach broadband speed, then it is likely that it is the problem of router
it is recommended to replace a better router or use al band router to get better service, WiFi language

6. When p2pool establishes a client, it will set an address to accept bitcoin in the p2pool network. In other words, when you connect to other people's p2pool on the Internet, the profits are all other people's. You can open your own p2pool client to mine. Here is a detailed tutorial.

7. According to the operation principle of the miner, the miner will continue to accept the tasks assigned by the mine pool, and return the calculation results to the mine pool. However, there is a delay in the communication between the mine machine and the mine pool network, and the invalid submission caused by the network delay is called the rejection rate.

8. Joining the pool alliance has two advantages for miners: one is that miners can get stable mining income; the other is that miners only need to be responsible for hash operation, and other things are handled by the pool, which improves the mining efficiency. In other words, by adding a large proportion of computing power in the mine pool collection network, it is far more likely and less risky for miners to obtain block rewards alone.

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:
