Super computer grabs bitcoin

1. I tell you, the computing power of home PC is too low. According to the difficulty of more than 900 million computing and programming, the computing power of a home PC is generally between 100 m and 600 m. if you dig, the money you earn in a month is not even one tenth of the electricity bill, so you need a mining machine. Now on the market, the machine specially optimized for the calculation algorithm of the generation of bitcoin is the miner. A miner can process 600ghash data operations per second. Without interruption, it can generate a bitcoin in about 10 days, which requires high computer configuration

it's not impossible that you can dig 100 in a day. To be exact, it doesn't take a day. It only takes less than a few seconds to win. The premise is that you can win "Tianhe No.2" which ranks first in the world.

2. It refers to the online wallet. Users who use bitcoin hot wallet generally do not hold the private key of bitcoin wallet directly. Even if they hold the private key, it is also the private key stored on the network. Therefore, it has the risk of being broken and stolen by hackers. But correspondingly, because bitcoin hot wallet is always connected to the network, it can provide users with bitcoin access service at a faster speed.

In fact, the mining calculation of bitcoin is to do math problems together. The problem stem is the transaction that needs to be recorded. By doing the problem, everyone grabs the bookkeeping right, and the miners can get system rewards and transaction fees. The feature of sha256 algorithm used in bitcoin is that it is easy to verify the known answers correctly, but it is very troublesome to get the answers, and it needs to try one by one. The miner who got the answer first was recognized by everyone as having snatched the right to keep accounts, and the reward was given to him. Let's continue to grab the bookkeeping right of the next question. In short, the significance of these calculations is only to ensure the stability and safety of the whole system, and there is no more significance

it is not comprehensive to regard bitcoin as a by-proct of computing. The generation and issuance of bitcoin, all the transactions and circulation in the bitcoin chain, and the stability of the bitcoin system are the purpose of computing and are integrated. Of course, in addition to maintaining the system, it does not proce other value and procts. This is also a black spot where bitcoin is accused of not being environmentally friendly and wasting resources. In general, bitcoin, as a milestone blockchain digital currency, is e to the huge value of a large amount of computing power investment and user trust. There is no doubt about that

4. Hehe, the idea is naive. The problem is very simple. At present, the network speed of bitcoin is 1861 petaflops. Tianhe two is 33 PETA flops
less than 2%<

the output of the whole network is about 150 per hour, and Tianhe can dig about 2 BTCs per hour, which is about $200
its power consumption is 24kw. Fifty cents per hour of electricity is 12000 yuan, or two thousand dollars

spend $2000 to generate $200. That's the effect The actual depreciation cost is probably higher than the electricity charge)

5. The overall principle is that the stronger the computing power is, the larger the proportion of bitcoin can be allocated. However, the speed of bitcoin generation is graally decreasing

technically speaking, it is completely feasible, because the algorithm is not complex and can be transplanted to the mainframe with a little modification. If it can be optimized for parallel computing, it will be more efficient
but in terms of cost, supercomputers are not cheap to use. Only a medium-sized and large-scale computer consumes tens of thousands of power every day, not counting the loss of the whole machine. As for supercomputers like Tianhe-1 and tianhe-2, the research and development costs and rental costs are still relatively high. Whether the excavated bitcoin can recover the cost still needs to be carefully considered.

6. January 13) is a milestone for cryptocurrency. 16.8 million bitcoins, or 80% of the total bitcoin supply, have now been mined. This means that the mining of bitcoin miners has become more and more difficult. What's more, governments of many countries have taken the opportunity to strengthen the crackdown on bitcoin "mines"
the total number of bitcoins is 21 million. As of January 13, 2018, 16.8 million bitcoins have been mined in the world, with 20% left, that is, 4.2 million bitcoins are waiting for everyone to excavate, facing the situation of "more than enough"
in November 2012, the new issue speed of bitcoin was reced to 25 bitcoins per block
bitcoin mining relies on the use of computer chips to calculate specific encryption algorithms. With the increasing scarcity of remaining bitcoin resources, the mining cost of a single bitcoin is also increasing. As long as the function of supercomputer is completely based on a specific encryption mathematical algorithm. Changes in bitcoin are soon over. And the time is very short.

7. Of course, I lost

in the past, a guy from the United States used his position to dig with a supercomputer, but it was found that...

it is said that the money he got was so little, even one tenth of the electricity bill was not enough!

8. Ask the experts

9. Brother, I advise you not to come. I'm an intern in the futures company now. It's very miserable. I'm a research assistant. I've been training for a week, but I haven't learned anything. My daily work is similar to that of a clerk.
