Mining difficulty and ore pool

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

Mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion

bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."

Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation before

since miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners

further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining

but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China

whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem

3. 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

4. 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. The difficulty of mining will become more and more difficult with the decrease of quantity and the passage of time. For example, Gehua chain routing bar has sold 3000 reservation codes in advance, and only those who get the reservation codes can buy them. The mining pool started on March 31, and only 3000 people scrambled for those coins. The more difficult it is to dig the later coins, the higher the price of Gehua coins, so the more people who come first earn.

6. The computing power and block output of the whole network can reach taobit http://www.taobtc.net/ See
1. First of all, as a node mine pool, the mine pool construction itself needs to add node files, showing the number of connections below the bitcoin wallet. After adding nodes, the number of connections can reach dozens or even more, depending on how many nodes you add, effectively recing invalid shares
2. How to fix the calculation difficulty of mining equipment for miners? Set it in your mining equipment startup bat
for example, if your single mining equipment is 10g, you can add / 1000 + 10 after the user name (wallet address) in the bat file. For example, in my bat - / 1000 + 10-p1, what does that mean? This means that your equipment is 10g computing power, and you use a fixed difficulty of 10g in p2pool mining. If you are a 1g device, write / 1000 + 1 at the back, so the difficulty is fixed and the efficiency of the device is effectively improved.

7. Data difference is determined by a variety of reasons, including display delay and data error. And it could be the pool. China's bitcoin mine pool and coin net mine pool are both emerging bitcoin mine pools, and the rate should be the first. As for accuracy, I don't know. I don't mine.

8. 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

9. 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

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.
