Bitcoin miner computer
At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip
the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system
extended data:
mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction
any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power
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 are considerable expenses in mining
in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive
Bitcoin miner is the equipment for bitcoin mining. The miner can be used as an ordinary computer
bitcoin miner can be USB miner or professional ASIC miner. It's true that bitcoin can be mined with ordinary computer CPU, but it's difficult for indivials to find bitcoin with ordinary computer
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin
special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below
this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high
so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers
if you want to mine through the new route generation 2 or 3, you need to connect an external mobile hard disk with a capacity of at least 64GB, and the higher the capacity is, the faster the interface speed is, and the easier it is to generate high revenue
Answer first, it will not be ended, but will be better P>
Central Bank launched DCEP instead of paper money, that is, to promote electronic payment, DCEP positioning is similar to RMB, but DCEP is just ordinary electronic payment, while WeChat and Alipay have other services. WeChat is the largest social platform in China, and Alipay has the largest domestic e-commerce platform. DCEP is only second or third choice. For the time being, DCEP can not end the era of WeChat and Alipay. At present, the era of Internet BAT p>
has gone too far to the TA era. It is the era of Tencent and Alibaba. As one of the top enterprises in the country, it will not be easily terminated. After all, it is the leader of private enterprises. However, considering the interest relationship between them, WeChat and Alipay's electronic payment platform may be nationalized, which is more concive to the development of enterprises. Not long ago, Mu Changchun, deputy director general of the payment and Settlement Department of the central bank, made a public speech, saying that it is not far away for the people's Bank of China to launch its own digital currency. This means that electronic payment is the trend of the future, and it is also the result of the central bank's compliance with the times. Electronic payment is one of the four new inventions in China, and domestic comprehensive electronic payment will lead the world< br />

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
1. In a narrow sense, blockchain is a chained data structure composed of data blocks connected in sequence according to the time sequence, which is a distributed account book that can not be tampered with and forged by cryptography
2. Broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code.
