What's the difference between mining in a pit

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. The main reason is that the distribution mode of bitcoin is different: according to the operation mode, the common bitcoin pools are as follows: PPLNs, PPS, DGM, P2P ool, etc.

PPLNs: (the purest Group Mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)

in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income

PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks

in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day

do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck

175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks

bitcoin home has a detailed introction.

4. Because it's not the ore that can't be mined

5. Mining is actually competing for the right to pack in the block
as tens of thousands of miners compete for the right to pack, the probability of a single miner seizing the right to pack is very small, and the output is very unstable. It is possible to grab the right once an hour or not once a year
in order to stabilize the mining output, miners often choose to join the mining pool. The mining pool integrates the computing power of a large number of miners and occupies a certain share in the total computing power of the whole network, so as to obtain a more stable mining output. After charging 2% ~ 4% of the pool handling charge, the output is distributed to the miners according to the miners' computing power
it's just like that it's hard for one person to win the lottery, so the mine pool organizes many people to buy the lottery together, and after winning the lottery, they are distributed to everyone according to the amount of contribution.

6. The mine pool is a team mining server. Corresponding mine pool address and server address. Bitcoin generates a block every 10 minutes, and there will be tens of millions of people competing. In the end, only one person owns the block, and no one else receives anything
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.

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

8. The coin'an mine pool is an existence worthy of many miners' choice. As one of the fastest-growing head exchanges, coin'an mine pool is an indispensable part in the ecological layout of the blockchain. For the development of coin'an's ecological strategy, coin'an mine pool will go online sooner or later, which is a very attractive choice for new people in the coin circle
the coin'an mine pool is similar to the coin'an exchange account, which makes it convenient for most miners to trade on the platform or make other distribution after they get income. It is safe and convenient in the long run.

9. I understand that this belongs to two modes. Self built cluster is much better than access to the mine pool. It has its own independent property rights and nodes, and the cost is relatively low. However, access to the mine pool is different. The property rights of mining machinery and nodes are controlled by the mine pool side, and the operating costs are high, so we earn less, Another point is that the rate of return of self built cluster is much higher than that of access to the mine pool, so it is not necessary to access the mine pool if self built cluster can be used.

10. There is no essential difference. It mainly depends on what kind of money you dig, how much difference you make in electricity charges and prices. Everything else is the same. You join the mine to dig
