What's the meaning of mine pool calculation
mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K
now the basic unit is GH / s, and several hundred g mining machines are very common
[bitcoin mining machine]
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
Mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it
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
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.
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
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
