BBC virtual currency master's impressions

1. The concept of bitcoin was first proposed by Nakamoto in 2009. It is a kind of P2P digital currency. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
it is this scarcity that makes the price of bitcoin soar all the way in the near future. However, there are different voices about the future development trend of bitcoin and whether it is worth investing
[bitcoin investment is the most risky investment you can make at present]
bitcoin.com is one of the largest bitcoin websites in the world. Due to the soaring price of bitcoin, the website has achieved great development this year. But Emil Oldenburg, its co-founder and chief technology officer, is skeptical about the future of bitcoin
in an interview with breakit, a Swedish technology website, he said: "I would like to say that bitcoin investment is the most risky investment you can make at present. There are extremely high risks in it." "In fact, I recently sold all of my bitcoin in exchange for bitcoin cash," he said Bitcoin cash, a derivative separated from bitcoin in August this year, has recently overtaken Ethernet as the world's second largest cryptocurrency“ When people figure out how bitcoin works, they start selling bitcoin. " Oldenburg once again stressed doubts about the future of the bitcoin“ He doesn't believe that bitcoin will become the kind of everyday currency that the world has always wanted
[if people invest in bitcoin, they are ready to "lose all their money"]
on December 19, according to foreign media reports, the head of a major British financial regulatory agency warned that if people invest in bitcoin, they are ready to "lose all their money". It also shows the opposition of the British financial regulator to the bitcoin. Andrew Bailey, director of the financial market conct authority, told the BBC that neither the central bank nor the government supports "money", so it is not a safe investment
buying bitcoin is similar to gambling and has the same level of risk, he said. "It's not a currency, it's not actually managed in the form of bitcoin," Bailey told Newsnight“ In terms of pricing, it's a very volatile commodity. If you look at what happened this year, I would remind people that we know very little about the price of the bitcoin. This is a strange commodity because the stock is fixed. If you want to invest in bitcoin, you should be prepared to lose money, which will be my serious warning. "
[next year we will see central banks start to hold digital currencies for the first time]
Peter Smith, founder and CEO of blockchain, a cryptocurrency wallet, said that it is expected that central banks around the world will start to hold digital currencies as reserve assets next year, and some central banks may start to issue their own "digital assets"
in an interview with CNBC, Smith said: "I think next year we will see, for the first time, central banks starting to hold digital currencies as part of their balance sheets." Mr Smith said central banks would be likely to buy bitcoin and Ethernet as reserve assets. Central banks now hold gold and foreign exchange reserves to allow them to act in the event of any market shock. The appreciation of bitcoin as an asset may mean that some monetary authorities will have to start holding the digital currency. "Bitcoin is already one of the top 30 currencies in supply, and as prices rise, this trend and the pressure to hold digital currencies as reserve assets will only rise," Smith said This view shows its optimistic attitude towards bitcoin and other digital currencies
as for whether bitcoin is worth investing, we can only say that every investor has his own vision and judgment.
2. "I don't want money, I don't want fame, I don't want people's worship, I just want not to be disturbed by the outside world."—— Craig Steven Wright, the self styled founder of bitcoin, told the BBC

who is Craig Steven Wright< Craig Wright, a 45 year old Australian born in 1970, has many different identities: he has a doctorate in theology, worked as a guest lecturer and researcher in computer science at Charlotte University, wrote many books, and is the CEO and founder of many companies, Most of these companies are in the field of virtual currency or computer network security

now, he has a new label for himself: the father of bitcoin<

looking for the father of bitcoin

the father of bitcoin is a god like existence. He is the first to publish the white paper of bitcoin and write the earliest version of bitcoin. Countless people admire his exquisite design ideas and neat code structure, but no one has ever seen him in reality

what people know is only a character with the pseudonym of Satoshi Nakamoto. He created bitcoin, but he hides his identity on the Internet and only communicates with the outside world through electronic means. No one ever knows who he is. In 2011, he said that he had a new project, and since then, he has faded out of the daily maintenance and development of bitcoin. Later maintainers even contributed more code than him in the project. However, since the emergence of bitcoin in 2009, people have never given up looking for the real identity of the father of bitcoin

the conjecture has never been interrupted. In view of the fact that there are very few traces of Satoshi Nakamoto, people can only find his existence from the only traces. Some people speculate that he is British, because there are English expressions like "bloody hard" in his words. Others speculate that he lives in the eastern time zone of the United States according to the timestamps of his few emails. Others speculate that he is a socialist in the Netherlands and a mathematician in Japan according to his ideas and pseudonyms, It's Irish students... Among all the suspects, Nick Szabo and Hal Finney are the two most widely suspected, and even appeared in new Yorker and Newsweek. However, the former denies that the latter is no longer alive. Even some people think that bitcoin's exquisite design must have come from a team. Satoshi Nakamoto is a group of people, not a person

ring this period, countless people jumped out and claimed to be the father of bitcoin, and were found to be pranks or scams countless times. This time, Craig Wright took the initiative to show his identity to the BBC, the economist and GQ. Will he end the mystery< This is not the first time Craig Wright has been associated with Satoshi Nakamoto, the father of bitcoin. At the end of last year, someone anonymously reported to wired and Gizmodo that Craig Wright was most likely the father of bitcoin. They provided Craig Wright with many emails, phone calls, financial records and so on. All kinds of signs show that Craig Wright and bitcoin are inextricably linked<

however, shortly after the report was published, wire overturned this conclusion based on some back tone situations: they found that Craig Wright's claim on LinkedIn that his degree did not match the facts, and his company claimed to have purchased supercomputers from SGI, which was also denied by the latter. Since then, the search for the father of bitcoin has been temporarily deadlocked. What's more, almost at the same time as the news, the Australian tax authorities launched a surprise investigation into Craig Wright and his company, but no one ever knew the specific reasons and results of the investigation. Craig Wright remained silent throughout the incident, but left Australia to work in his London office

until today, six months later, on May 2, 2016, he took the initiative to stand up and claimed on his blog that he was Satoshi Nakamoto, the father of bitcoin

why now

Craig Wright told the economist that he didn't disclose his identity for the sake of fame, but just to correct the public misunderstanding of him. According to him, in the months of silence, all kinds of public unfounded suspicions not only affected him and his work, but also his family, employees and everything. In addition, he also wants to break people's negative views and misunderstandings about bitcoin

if he is really Satoshi Nakamoto, his wealth is amazing. At present, the value of bitcoin in circulation is about US $7 billion, and Satoshi Nakamoto, as the earliest prospector of bitcoin, is estimated to hold as much as US $450 million in bitcoin on hand, although with the disappearance of Satoshi Nakamoto, the money seems to be covered with st and has never been transferred. Craig Wright said that with his comeback, without affecting the exchange rate of bitcoin, he will slowly turn this money into cash for his research projects

Why did you think of using the pseudonym Satoshi Nakamoto at that time? Craig Wright says the name comes from a 17th century Japanese philosopher and businessman, Tominaga Nakamoto, who started a critical movement against rules and supported free trade. As for why Satoshi, Craig Wright didn't give a positive answer, but told reporters that he wanted to keep this part mysterious

however, since you have chosen the bright identity, how much mystery can you keep<

uncover the mystery

in view of all kinds of doubts that Craig Wright suffered at the end of 2015, it is obvious that more strict examination is needed to prove that he is the father of bitcoin this time. The economist tries to find out whether what he said is true through four questions:

does Craig Wright have evidence to prove that he is Satoshi Nakamoto? For example, only Satoshi Nakamoto has the key
What's the explanation for the queries and loopholes we encountered last time

as the father of bitcoin, is it true that it has the matching technology and strength background
do you believe the people in the circle who have had contact with Satoshi Nakamoto online

it's easy and difficult for Craig Wright to proce evidence that only Satoshi Nakamoto himself can have. Here I want to mention the basic composition of bitcoin. Just like a bank account, everyone can have multiple bitcoin accounts, and each independent bitcoin account has two key components: 1) a string of bitcoin addresses composed of 27-34 letters or numbers; 2) A private key for encryption and authentication; The holder of bitcoin can generate a digital signature by encrypting information with his private key. In addition, bitcoin as a kind of currency, in order to achieve incremental, it must rely on mining, and the ability of mining comes from your computer computing power. They are the banknote printing machines in the bitcoin world. Every new mine will be bound with its corresponding bitcoin address. As the first miner, Satoshi Nakamoto should have these private keys. In addition, Satoshi Nakamoto was the first person to trade bitcoin. In that year, he transferred the bitcoin g up in block 9 to Hal Finney, who was also suspected to be the father of bitcoin and is no longer alive

therefore, according to the strength of the evidence, Craig Wright should basically have the private key of jiukuang, and it would be better if he could provide earlier mining areas. And if he can transfer another account, it will be more credible

in the process of verification, Craig Wright encrypted a segment of Jean Paul Sartre's speech in 1964 when he refused to accept the Nobel Prize for literature with the private key of jiukuang, and published the process on his blog. At the same time, he showed the economist the verification process of Yikuang in private, and there were two witnesses in the whole process: Jon matonis and Gavin Andresen, both members of the bitcoin foundation, who once served as the chief developer of the whole bitcoin community after Satoshi Nakamoto faded out

but the problem is that the encrypted text is prepared in advance, which does not mean Craig Wright really has a corresponding private key, but may have been generated in advance. In addition, Craig Wright did not make a real transfer. According to him, the bitcoin in his name is currently in the name of a trust, and he can't use it directly. In this case, the Economist asked whether they could provide a piece of encrypted information, but Craig Wright refused. To sum up, he meant: I've demonstrated so much, believe it or not

in addition, with regard to previous resumes, Craig Wright said that some of the resumes previously written on LinkedIn were not true, but his purpose was not to disclose too much personal information and deliberately create smoke bombs. According to his latest resume, he does have three master's degrees at Charlotte University, a doctoral dissertation in computer science is under review, and he is also studying for a master's degree in finance at the University of London. These qualifications and work experience have been basically confirmed<

as for whether they actually bought supercomputers, Craig Wright provided an explanation from the SGI agency in Australia. Although SGI headquarters far away in Silicon Valley denied the existence of the transaction, they did not deny it. It may also be a grey transaction through informal channels, and they did not comment on it

as for the tax department, Craig Wright directly denied all conspiracy theories and said that he was not involved in any financial crimes or tax evasion. The Australian authorities only discussed with him about the tax laws of bitcoin on some projects he carried out, such as bitcoin bank. He left Australia for the UK only because London is better suited to run a technology finance company< However, it seems that things are not so simple

Craig Wright is a text lover with nearly 100 conference reports, articles and books. In addition to most of the short stories related to computer security, other words cover a wide range of fields: economy, terrorism, risk management and so on. He said that he had several papers on bitcoin under review, and the economist had read some of them. In their original words, although not extraordinary, it was OK

based on Craig Wright's large amount of words, Juola & Associates, a stylistic analysis company, compares Craig Wright's words with the bitcoin white paper published on the Internet by Satoshi Nakamoto
3. It seems that I have heard before that its founder had a record of engaging in MLM
Vicat China has internally confirmed that Vicat is "direct selling", but it has not obtained the domestic license. In the list of 61 direct selling enterprises published by the Ministry of Commerce, the reporter did not find the name of Vicat
bitcoin and other virtual currencies are open source programs, and the parameters and methods of their total amount limit are displayed in the open source code, so as to show the operation mechanism of the currency system openly and transparently. However, Vicat does not disclose its source code, which in itself violates the basic principles of virtual currency. " In addition, bitcoin and other virtual currencies are scattered transactions spontaneously formed in the market, and after the scale is formed, the third party graally establishes an exchange to complete the transaction. The Vicat is issued by itself and traded on its own platform. The so-called cooperation with the bank is nothing. Vicat currency, which has problems in basic properties, has high investment risk, so investors need to be cautious Netease News)
in the coin circle, bitcoin home and many mass media have also exposed the pyramid scheme of Vicat under the guise of bitcoin
economists point out that Vicat is a virtual currency with the nature of multi-level pyramid selling, and its investment risk is extremely high, so participants should be cautious Official website of Ministry of Commerce of China)
4. Careful friends should find that in the past, every issue of Finance and economics Lang Yan had to write the impressions of both literature and martial arts, but he didn't write the impressions of the episode "private banks are coming" on January 20, 2014. The reason is that such
topics are too boring for people like me. I feel that this kind of program is totally deceiving the fans. So after watching it, I didn't write my impressions to express my disdain for bad programs. The episode
on January 27 was broadcast before the festival, just ring the Spring Festival holiday, my laptop broke down. Back home, I didn't have to surf the Internet, so I didn't have time to watch this issue of Finance and economics until I came back from work on February 8, 2014. At the moment when I was almost desperate for Caijing Langyan, whose program quality was getting worse and worse at the end of 2013, the bitcoin truth of Caijing Langyan on January 27, 2014 really brightened my eyes<

a rare and good-looking episode of Caijing Lang Yan

there are many highlights in this episode, including the fierce quarrel between Lang Xianping and the CEO of bitcoin. Lang Xianping, a well-known man, had a quarrel with a sluggard and swearing woman in the program, and the audience of the program had a good time seeing the letter. It doesn't matter what Lang Xianping said. The important thing is that there are such passages in such a national broadcast. I believe in Taiwan, this program has become a variety show

the hanging wires from those two bitcoin websites are well prepared. Lang Xianping was obviously prepared and had investigated both of them. Ice suck is also very well prepared. Unlike the past, when the cold feeling always comes to the program, speech is always not felt enough.

it is the trend of human development that virtual currency replaces physical currency

you just need to think about how much cash you have in your family and what is the ratio of these cash to the total funds of your family. We can see that our property has been digitized. Our savings become the numbers on the savings book and bank card. Our wealth is stored in the form of digital hard disk, in the form of binary coding through the computer network wealth data

the reason why we have introced computer technology in managing wealth is that it greatly facilitates us to manage the wealth of indivials and housekeepers. Just like the continuous simplification of money, virtual money will eventually replace physical money, which is the inevitable trend of human development. Because from any point of view, virtual money is more than physical money

bitcoin is not the trend of virtual currency

but bitcoin is not the trend of virtual currency. The reason is that bitcoin is not issued by any government. If bitcoin was issued by the people's Bank of China, he would not have any arguments
however, he is a mischief of non-governmental organizations, so it is doomed that he will not come to a good end. The central banks of the world's major countries, including the people's Bank of China, are likely to fake a bitcoin at any time, rather than let bitcoin have the function of currency


no matter how good bitcoin is, it will not have a good result. Because issuing currency is the super privilege of the government, he moved the cheese of the government. How can the relevant departments tolerate this? Although Lang Xianping didn't make too many mistakes in his speech, I agree with him, but his speech is really a little angry. Because I feel that he is flattering the relevant departments again, not that his own view is wrong<

I won't buy bitcoin unless you give it to me

no one wants to admit it, but bitcoin is really a proct of computer games. He can't generate any value unless someone more stupid than you is willing to buy him. So, I'm not going to buy bitcoin unless you give it to me< Not long ago, I met a top student from Peking University. I used to study computer software development and Android. This guy is very interested in bitcoin. He talks to me all day about how awesome bitcoin is. At that time, I was dismissive of what he said, and I felt that this person was a little different. Facts have proved that his investment is really not good, and he is even worse than me. Bitcoin didn't last long, and soon became impotent

Lang Xianping said that he would not give bitcoin to him. I think he is lying. I would like to make a serious statement here, who wants to send me bitcoin, I still want it. Of course, if you don't want me to return the gift. Ha ha. Finally, I wish you a happy new year. This is the first diary written by Wenwushuangquan after the Spring Festival in 2013.
5. After watching the video of MMM's financial pyramid, I felt a lot. First of all, I felt Mr. mavroji's great financial ideas and ideas, and admired Mr. mavroji's wit and courage. Looking back on the hard course of MMM company, we deeply realize the influence of politics on the market economy and the influence and destruction of politics on the new economic concept. In the 1990s, Mr. mavroji was one of the most influential figures in Russia. His brother Anton and other three people set up MMM company, which achieved crazy results. The final stock benefited more than 40 billion rubles per day. However, with the intervention of the government, he soon went bankrupt and was sentenced to four years and six months (I have an impression of that in my mind). After the incident, mavroji vowed not to touch money with a finger. However, mafroji is disgusted with the unfair financial system in the world today! He believes that in this world of money, the vast majority of people have become slaves of money, which is inhumane, unfair and unfair. In order to break the monopoly and exploitation of the financial system, he is determined to build
6. The prices of bitcoin and Ethernet continued to decline sharply. According to the offer of coindesk, a trading platform, bitcoin was as low as US $7559 today and the latest was US $7670, down 191 US dollars or 2.44%, with a market value of US $130 billion. Ethereum, another virtual currency, recently reported US $521, down 31 US dollars or 5.72%, with a market value of US $51.19 billion
it is worth mentioning that the global market value of digital cryptocurrency was about US $372.9 billion last Wednesday, and it was US $310.4 billion on Thursday. The overall market value of digital cryptocurrency shrank by US $60 billion in 24 hours.
7. It's not hard to explain. It's almost the same as the prices of commodities, futures, gold and silver, and foreign exchange trading platforms. The price may vary a little, but it won't be too big. If it is too big, it will lead to moving bricks. There is a big difference between the domestic and foreign bitcoin prices in 2013. Basically, domestic bitcoin prices are higher than foreign ones. Therefore, many people move bricks to earn a price difference, that is, they buy bitcoin from abroad and sell it on the domestic trading platform.
8. BBCT is a financial trading platform. Generally, many financial institutions trade on it.
