What does the difficulty of mining represent

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. At present, with the increase in the number of people mining in various currencies, the difficulty is also increasing. If you mine with a single computer, the possibility of digging out a block is relatively small. Take BTC for example, it is very likely that you will find one in half a year; If you connect your own miner to the mine pool, you can ensure that you have a basic income every day, which is relatively stable for miners. The premise is to select a suitable ore pool according to different currencies. Generally speaking, the current mining pools: ant mining pool, fish mining pool, coin printing mining pool, viabtc, flypool are all pretty good

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.

5.

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

6.

Mining is a process of increasing the bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledger

in the past, ordinary computers could be used to mine, but now it is basically impossible. Because the operation mechanism of bitcoin is becoming more and more difficult, the performance of ordinary computers at home is limited, and it is difficult to decrypt bitcoin. Now there are new machines on the market, professional coin digging machines, called mining machines

Mining precautions:

if you want to invest in virtual currency mining, in addition to the need to buy mining machines, you also need a suitable site and a special person to take care of and maintain it. Of course, the appropriate electricity price is also essential. However, the general investors will encounter a series of difficult problems from the beginning of purchasing mining machines

trusteeship, in a simple sense, is to put the purchased mining machines in the professional mines of trusteeship enterprises, and then the trusteeship enterprises provide you with ore pools and special personnel to maintain them. Of course, the electricity prices that these trusteeship enterprises can get are very low, and there is no need to worry about the legitimacy of these enterprises. They must all meet the national standards

7. Most businessmen and speculators are always interested in things that can be turned into money immediately. Bitcoin is one of them. The specialization of ASIC chips leads to the market separation between bitcoin mining and other Shanzhai coin mining
when the vast majority of video card mining machines and CPU mining machines are in a mine disaster, bitcoin mining with ASIC mining machines will not be affected. As the first big man in the virtual currency circle, bitcoin has become a deep-rooted belief in the coin circle. The total number of 21 million bitcoins also determines the transaction type and value-added of bitcoin
although bitcoin has begun to be recognized by most people, it has not really replaced the world's currency to fulfill its original intention, but it has become a collection beyond gold. The inflation of money, the rection of the total amount of mining and the increasing difficulty of mining all determine its future market prospects. The value-added has been firmly established, so people will rush to dig for mines, Because the bitcoin is actually worth more than gold

8. Before trench excavation, use measuring instruments to measure the average elevation within the excavation area. At this time, carry out plane positioning first, and then calculate the average elevation. After the preparatory work is finished, you can use the design drawings to calculate. Generally, as long as you calculate the original landform elevation, you can calculate the excavation height well. Here are two elevations: the original ground elevation, the design elevation, and the design elevation, The former is obtained through actual calculation, while the latter is expressed clearly in drawings

9. Look at the situation of the exchange, whether all the trading time limit or small exchange running

10. There is still a big difference, because it is more difficult to mine cryptocurrency, which means that the effect of mining is not as fast as in the past, which will prolong the mining cycle.
