Pool cannot be changed
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
you may have to dig for 5 years to get a block. Team mining is that once anyone in the team gets a block, they will divide the currency in the block according to their performance, so that they can get bitcoin quickly.
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items[ 1-2]
PPS means that the gold you dig is stored in the mine pool, and then transferred to your wallet after a certain amount. The handling charge is relatively high. PPLNs is generally more common in p2pool. When you dig the mine, it is directly stored in your wallet, and there is no handling charge. At present, the more popular is p2pool, which is relatively safe at present, and it is also highly praised by foreign heroes
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)
2. Operation steps of al screen
1. First, connect the external display and computer graphics card interface through any two cables of VGA / DVI / HDMI
2. After the connection is successful, enter the desktop of the computer system, right-click the blank space of the desktop, and select display settings
3. If the connection is successful, you can see that there are two displays
4. In the display interface, select expand these displays under multi display settings, and then the two displays can be displayed normally
5. If the line detection is OK and still can't be displayed, right-click the desktop and select NVIDIA control panel
6. Find [set multiple monitors], and then check the monitor we want to use<
3. Multi screen display method
hardware requirements:
in addition to supporting al screen hardware conditions, some computers need to enter BIOS settings to find relevant options. If it cannot be found, it means that the motherboard does not support it, please refer to the following operation
steps to enter BIOS:
1. Turn on the computer to enter BIOS, find the options of [devices] - VIDEO setup], and click enter
2. Select the select active video option and set it to IgD mode, and set the multi monitor support option to enabled mode
3. After setting, click F10 and select Yes to save
4. After restarting the operating system, right-click in the blank space of the desktop, find the integrated graphics card console program from the menu, and set the multi screen display.
