1. bitcoin is hyping. It has nothing to do with hackers
2. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of money circulation
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
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 will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
< H2 > extended data
users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold diggers by repeatedly solving riddles to provide the required numbers for bitcoin network. If the user's computer successfully creates a set of numbers
bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

3. Stars emit light and heat by fusing lighter elements into heavier ones. All kinds of nuclear fusion reactions take place in stars all the time, the most important of which is the reaction of hydrogen fusion to helium
in stars with different mass, the reaction path of hydrogen fusion to helium is also different. In smaller stars, the fusion reaction of hydrogen nuclei takes place through proton proton chain reaction. The process is shown in the figure below
whether it is to split the iron core (fission), or to continue to increase the weight of the iron core (fusion), we need to increase the energy of the iron core. Inside a star, however, there's not enough energy. In this way, the energy generation of the star will stop, and the radiation pressure used to resist gravity will disappear. The star will continue to contract, and the speed of contraction will be faster and faster. Finally, the speed of external matter falling to the iron dominated stellar core will exceed 100000 km / s, but when it reaches the iron core, it will hit an extremely hard "wall", and the speed will instantly drop to zero. The huge kinetic energy will be instantly converted into heat energy, heating the iron core to billions of degrees. The outer layer of the iron core will explode at a very high temperature, exploding the falling material in the outer layer. This process is called "core catastrophe". This is a supernova explosion
at the same time of explosion, under the action of huge energy, a part of iron in the outer layer of iron core will absorb energy and form elements heavier than iron, from 27 element cobalt to 92 element uranium. The iron inside the iron core will press the electrons outside the iron nucleus into the nucleus under the pressure of implosion, and combine with the protons in the nucleus to proce neutrons. All the iron inside is converted into neutrons. When the outer shell is blasted and dissipated into space, the center of the star is exposed and becomes a neutron star with huge mass and small scale
after the stellar matter from hydrogen to uranium dissipates into space, it will mix with the original interstellar matter in space to form interstellar cloud, and form new stars and planets around stars under the gravitational disturbance. This is how our sun and earth came into being. That's how everything on earth except hydrogen and helium comes from
This is the case with nuclear fusion reactions on stars
we are all the ashes of a supernova that erupted billions of years ago
4. As far as I know, more than 180 MCN organizations and nearly 3000 KOLs have settled in the brushing platform. Even my favorite "Chen Xiang 6:30" has settled in the brushing platform for a long time
since I used brush treasure for more than half a year, I found that there are original and fresh videos on brush treasure every day, and compared with other platforms, the proction is more elaborate, and funny videos can make you laugh more
in addition, you can also get Yuanbao by brushing the video on brushing treasure. Yuanbao will be converted into the balance, and the system will also give brushing diamond at random. The Yuanbao you get can be used to reward the comments you are interested in or write well
Yuanbao, yu'e and brush diamond can be used to buy gifts for the anchor when we watch the live broadcast. This kind of playing method is not available on other similar platforms. It should belong to the original playing method of brush treasure, which is one of the reasons why I always use brush treasure. Of course, the content on brush treasure is also the reason why I insist on using brush treasure

Because I have been trading here for some time, people in the circle know that the trading depth of fire coin is relatively large.
6. Q. As a hardware DIY based official microblog, why do you pay no attention to bitcoin? A: Bitcoin first came into contact with video card evaluation. Two years ago, bitcoin mining, as a very important general-purpose computing application of GPU, entered our field of vision, and has been listed as an important test project of video card in addition to games. That is to say, a few bitcoins that I accidentally g up when I was doing the video card evaluation in those years are now worth more than ten thousand... Related evaluation: can I make money even if I hang up? Teach you how to use graphics card to mine and earn US $2011-07-29q. What's the principle of mining? It's a waste of electricity. It's not environmentally friendly! A. Who owns the newly issued US dollars and RMB? As we all know, it certainly does not belong to you. Not only can you not get it, but the newly issued currency will dilute the purchasing power of your existing currency. The design idea of bitcoin is similar to that of gold, the king of money a hundred years ago. The newly issued currency is mined by miners and owned by miners or factories. Depending on the
computing power of your device, the amount of money you dig varies, but anyone has a chance to get a new issue of bitcoin. Even if you don't mine, you don't have to worry about the devaluation of bitcoin in your hand because others have g a lot of bitcoin, because the issuing speed of bitcoin is determined by a fixed algorithm, and the total amount will infinitely increase to a constant value over time. Bitcoin has no central bank. All the transactions and foreign exchange settlement operations are done on the miners' computers. In return, some new bitcoins will be awarded to miners according to the amount of computation. However, the calculation of currency transactions on miners' computers is only a small part, and most of the time is spent on data encryption, decryption and packaging, but this is also a necessary step, otherwise no one can guarantee the security of bitcoin. Because of this, many people say that bitcoin mining is not environmentally friendly and does boring and meaningless operations. Q. How to mine with graphics card? How to convert bitcoin into RMB? A. See bitcoin boom! Making bitcoin with graphics card mining tutorial 2013-03-28q. What is a mining machine? Is it reliable? A: Two years ago, the graphics card was the fastest mining equipment to obtain bitcoin (the performance of a card can reach dozens of times of the top CPU). Nowadays, many organizations and organizations have developed special processors for the sha256 hash encryption algorithm of bitcoin. The performance is dozens of times of the top graphics card today, and the power consumption is very low. In fact, the principle is easy to understand. CPU and GPU are general-purpose processors, on which various programs can be run, but the speed is not the fastest. Processors specially designed for a certain kind of application, such as hardware CODEC / decoder (commonly known as hard solution) built in graphics card, are much faster than CPU / GPU soft solution. Nowadays, mining machines are very popular, but most of them are in the scheled state rather than in stock, and there are very few related evaluations. Naturally, we are very interested in them, and we want to know how much faster they can be than graphics cards? Is it reliable? What are the benefits? We take the risk to book, and we will make evaluation and share it with you as soon as we get it. Q. What is the difference between bitcoin and qcoin? A: Q currency is not a virtual currency strictly. It is equivalent to a kind of voucher or supermarket shopping card. It will not appreciate or depreciate. Its value is strictly equivalent to RMB. At most, it can give you some discount when recharging. Bitcoin is a new kind of electronic virtual currency, which does not depend on any government or any legal currency. Due to its characteristics of going to the central bank and distributed computing, no one can intervene and monitor the transaction of bitcoin, and the currency circulation is strictly implemented according to the original algorithm. So theoretically, there will be no inflation. To put it bluntly, paper money is worthless, but the government says that if it can buy something, it can. Money is based on credit. If you trust it, it's worth nothing. If you blindly abuse it, your purchasing power will naturally decline. When your own currency is not trustworthy (think about the paper money that was issued indiscriminately before the KMT's defeat in Taiwan is not easy to use as toilet paper), people will choose to accept the relatively reliable currency of other countries or gold. As countries around the world are competing to start the banknote printing machine, bitcoin will continue to appreciate compared with other countries' banknotes. With the improvement of bitcoin's influence, bitcoin will appreciate significantly. Imagine how many US dollars, RMB and bitcoin are in circulation around the world? In the past, some people used to say that bitcoin should not only be converted into hundreds of dollars, but also hundreds of thousands or even millions of dollars. Now, it's not impossible to calculate by the total circulation. It can be said that bitcoin will have a bright future in the long run unless there are problems in its own system, or it is suppressed by the U.S. government (because letting bitcoin develop may threaten the status of the U.S. dollar as a global currency). Q. Invest in bitcoin? A. Like stocks, gold and foreign exchange, bitcoin investment is inevitably risky. However, only when there are risks can there be returns. Bitcoin doesn't have to look at the face of the government and there is no inside information. Therefore, I think investing in bitcoin is more reliable than investing in stocks and foreign exchange. If you want to know more about the mechanism and principle of bitcoin, you can search online + Google by yourself. Although the author and some colleagues think that it is like special currency very much, we still hold a neutral attitude towards the emerging virtual currency existing in the network. We hope that we can weigh the risks by ourselves and do not blindly listen to other people's opinions and act according to our ability. ■
