Requirements of bitcoin transaction for computers

1.

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

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

3. Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. Under normal circumstances, an ordinary home computer can bear up to 1000h / s of computing power. According to the hash collision data of bitcoin 3 million times per second, if it is just an ordinary home computer, even if it is mining 24 hours a day, it can dig up to 0.0018 bitcoins a day. It takes at least 556 days to dig out a complete bitcoin. If it is not lucky in the middle of the way, it will be difficult to dig out a complete bitcoin, It may take more time

4. This should not have too many requirements, generally not less than 4 megabytes

the founder of bitcoin, Tsung Nakamoto, left the bitcoin project in 2010 and became one of the most mysterious figures in the coin circle. Bitcoin is made by mining. Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.

Beijing, November 13 (reporter Wei Xi) - the people's Bank of China publicly responded to market rumors on the 13th that it has not issued legal digital currency, nor authorized any asset trading platform to trade

recently, it is reported that the people's Bank of China has issued legal digital currency, and some institutions falsely use the name of the people's Bank of China to trade relevant digital procts under the title of "DC / EP" or "DCEP" on the digital asset trading platform

in this regard, the Central Bank of China has made it clear that legal digital currency has been studied since 2014 and is still in the process of research and testing. Neither "DC / EP" nor "DCEP" traded in the market is legal digital currency, and the launch time of legal digital currency transmitted through Internet is inaccurate information

extended information:

the people's Bank of China reminded that the current online dissemination of the so-called legal digital currency issue, as well as the behavior of indivial institutions trading on the asset trading platform by using the name of the people's Bank of China to launch "DC / EP" or "DCEP", may involve fraud and pyramid selling. Please raise the public's risk awareness and do not believe it, Prevent the interests from being damaged

To this end, Mu Changchun, director of the digital currency Research Institute of the Central Bank of China, also launched a seven lecture open class to solve the doubts and doubts of the outside world. Mu Changchun said frankly in the open class: the functions and properties of the central bank's digital currency are exactly the same as paper money, but its form is digital

"our definition of it translates into 'digital payment instrument with value characteristics'". The digital currency of the people's Bank of China should adopt a two-tier operation system, that is, one is the central bank to the commercial banks, the other is the commercial banks or commercial institutions to the ordinary people End)

6. Four 290 graphics cards are selected in the configuration list. This is mainly because the 7990 graphics cards on the market are out of stock, and the performance of 290 is much higher than that of 280x. The official quotation is more than 3k, but it is not impossible to get the goods at the price of 2700-2800 in the actual market, so 290 graphics cards are selected. The purchase of the chassis is particularly important. The game fierce tiger shark chassis with the whole tower structure has good heat dissipation, and the 10 expansion slots are enough to control 4 graphics cards. The power supply is the cool all-in-one water-cooled radiator, and the effect with the 4th generation CPU is quite good. The price is also quite appropriate.

7. The demand for CPU is not particularly high, mainly for graphics card. You have to use the top level of a card to brush the block
just a game card, no need for a professional card. It's usually hd7990. Install multiple blocks for crossfire.

8. Bitsend (BSD) is a cryptocurrency or a digital asset. Today's price of BSD is US $0.01006654, with 24-hour trading volume of US $192.05 One is to move bricks on the floor, that is, to buy and sell different virtual currency trading pairs on the same exchange, and make use of the price changes of different virtual currencies reflected by these trading pairs to earn the price difference of currency trading. The whole process is like "moving bricks" back and forth between different currencies. The price difference of moving bricks in the field is relatively small. Usually, the robot is used to move bricks automatically. In fact, the threshold is not small

at present, it is popular to move bricks outside the market, buy virtual currency in exchange a with low price, and then sell it from exchange B with high price to earn the price difference between buying low and selling high

the real pursuit of moving bricks arbitrage is to carry out trading operations between different platforms when there is a large price difference, and carry out risk-free arbitrage. But "no risk" is not equal to "no cost". Such operations consume a lot of time and capital costs. Before arbitrage opportunities to cover handling charges appear, we need to wait patiently. At the same time, it also means that we need to bear the risk of currency price rise and fall

What's more, it seems that moving bricks outside the field is easy to operate and the threshold is not high, so there are many routines. On the mainstream exchange platform, a usdt costs 6.55 yuan. Some people say that its exchange can sell for 6.85 yuan. Do you find "business opportunities" right away? I bought usdt at 6.55 and sold it on this exchange with a premium. Isn't it unprofitable? So, you may have made an attempt with 1000 RMB carefully, and found that the platform can indeed sell at this price. You pondered "it seems that this is true", but did not know that this is called "invite the emperor into the Urn". Then you boldly invested tens of thousands, or even hundreds of thousands, and slowly found that the platform has various means to make your transaction and currency withdrawal difficult, until one day the platform ran away

last year, we introced an "Iranian exchange scam" in the name of Iran's regional exchanges, which often have bitcoin premium. We cheated them in a few months
