Calculation ability of white card miner B

1. If you buy a miner, you can go to digyi mining to have a look. I bought one a few days ago, which has high calculation power.

2. From the user's point of view, bitcoin is a mobile application or computer program, which can provide a personal bitcoin wallet with which users can pay and receive bitcoin. This is how bitcoin works for most users

behind the scenes, the entire bitcoin network shares a public ledger called "blockchain.". This general ledger contains every transaction processed, so that the user's computer can verify the validity of each transaction. The authenticity of each transaction is protected by the electronic signature corresponding to the sending address, which enables users to have complete control over the bitcoin transferred out from their own bitcoin address. In addition, anyone can use the computing power of specialized hardware to process transactions and get a bitcoin reward for it. This service is often referred to as "mining."

bitcoin mining has gone through three stages of development. When bitcoin was just born, the price of bitcoin was very low. People just took bitcoin as a game and used their ordinary computers to mine. However, in 2012, with the rise of bitcoin price, people found that the mining speed of graphics cards was fast, so, People began to buy a large number of graphics cards and assemble them for mining, commonly known as "burning graphics cards"; The third stage is the well-known ASIC miner mining. Since Avalon proced the world's first ASIC bitcoin miner, bitcoin mining has been completely subverted, and mining has become a special professional thing.

3. In the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions a mining machine can do per second is the representative of its "computing power", and the unit is written as hash / s, This is the so-called proof of work mechanism (POW)
recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the soaring computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race. This is the meaning of computing power. I would like to know more about it Please accept)

4. Because the mining algorithm is special, the mining efficiency of the graphics card has nothing to do with the interface bandwidth, and has nothing to do with whether there is a fire (several cards can be of different models). The computing power depends on the ability of each card. If six cards of a machine are of the same model, even if all pcielx ports are in the mode of 6X1, of course, the graphics card has the function of high temperature automatic frequency rection, and multi card should pay attention to heat dissipation.

5. Digital currency mining, we often mention a word is mining machine computing power, such as: Maya D2 Ethernet cloud computing power, Maya X1 bit cloud computing power. In fact, the meaning of computing power is very simple. It represents the measurement of the computing power and performance of the mining machine. Specifically, it represents the number of operations of the overall hash algorithm of the mining machine per second.

6. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.

8. I did. Oh, I didn't lie to you

9. There is no doubt that it can be surpassed. Although tianhe-2 has super computing power, it is not specially used for bitcoin mining. Bitcoin ASIC miner is specially designed for bitcoin algorithm, with strong computing power. Some netizens calculated a sum of money, and converted the computing power of tianhe-2 into mining efficiency. About two to three bitcoins can be g out in an hour, which is 15000 yuan. That's 360000 yuan a day. Mayor Chen Jianhua said that tianhe-2's daily electricity bill is 300000 yuan, which seems to make a little money. However, if labor costs, depreciation of machinery and other costs are taken into account, "mining" will not make much money. This is the result of last year's calculation. According to the current difficulty of mining, the profit is much less than this

at present, bitcoin mining is a very professional business, which has graally developed into an intensive large mine. The upgrading of bitcoin miner is very fast. Take Avalon miner, the mainstream miner in the market, as an example. At present, three generations of chips have been upgraded, and the fourth generation is expected to come out soon. In the future, it can be predicted that mining will graally move towards concentration, retail investors will graally disappear, and mining will have a large-scale effect.

10. The mining capacity of CPU is insignificant in front of GPU. You see which supercomputer is piled up by CPU. And mining is not graphics. Strictly speaking, it's a computing card.
