recently, the identity of Satoshi Nakamoto, the father of bitcoin, was accidentally exposed, which made bitcoin, which had graally faded out of the public's view, hot again. However, Craig, an Australian businessman with low-key and simple daily behavior, is still in the market; It took only five days for Craig Wright to admit that he had no courage to give up and prove that he was Nakamoto
not surprisingly, the mystery of "Nakamoto Tsung" will continue
"the twists and turns of Zhongben Cong's identity have not brought significant impact on the bitcoin market," Li Qiyuan, President of bitcoin China (BTCC), said in an interview with the first Financial Daily yesterday (May 9). As an innovative thing, bitcoin has been able to survive and grow steadily in the past few years, marking a kind of success. Liu Shengjun, executive vice president of China Europe Lujiazui Institute of international finance, is worried about the development prospect of bitcoin. "At present, no government is willing to give up its management power and accept bitcoin to replace legal tender."< On November 1, 2008, Nakamoto published a research report in a secret cryptography discussion group, in which the concept of bitcoin was first proposed. In 2009, the world's first bitcoin algorithm software appeared. In just four years after that, the price of bitcoin increased by hundreds or even thousands of times, which eclipsed other investment targets
as the creator of bitcoin, "Nakamoto Tsung" not only grasps the most core technology, but also increases people's curiosity and speculation about his real identity because of its huge wealth brought by about 1 million bitcoins (the current price of one bitcoin is about 2970 yuan)< On May 2, Wright publicly told several major overseas media that he was the so-called "Nakamoto Tsung", the founder of bitcoin, which aroused heated discussion in the market<
(the price trend of bitcoin in the past year)
Wright, 46, is a computer scientist and an entrepreneur. When he introced himself at the 2015 bitcoin investor conference, he said that he was a scholar, engaged in business research, and had a doctor of law and a master's degree in statistics
according to foreign mainstream media, Wright confirmed his identity as "Nakamoto Tsung" from a technical point of view by using the bitcoin owned by the founder of bitcoin. Wright also said publicly that it was not easy to make a decision to disclose his identity, and the reason for his clarification was his love and concern for his work, which he "hoped to eliminate the false legends and worries surrounding bitcoin"
as the Internet world continues to argue about Wright's real identity, the plot takes a major turn< On May 6, Wright suddenly published an open letter entitled "I'm sorry", saying that he "has no courage" to continue to prove his identity as "Nakamoto Tsung"
"I believed that I could end the years of hiding and hiding. However, with the events of the past week fermenting, I was going to publish the evidence that I had the initial block, but I couldn't stand it. I don't have the courage. I can't do it. " Wright said<
Wright once said in his public identity that he did not want money, nor did he want to be famous, nor did he want to be worshipped, but only wanted to be alone. Li Qiyuan told China Business Daily that if he really wanted to live his own life, why did he suddenly choose to expose his identity
obviously, the emergence of Wright has not completely ended the mystery of "Nakamoto" and investors are more concerned about the impact of "Nakamoto" on the price of bitcoin
Gong Ming, the founder of blockchain pencil, told the first financial daily that the identity of "Zhongben cong" will not have a substantial impact on the market, but is more symbolic. Unless "Nakamoto Tsung" sells a lot of bitcoin, it will not have an impact on the price of bitcoin. "From 2009 to now," Nakamoto Tsung "is not a person who has a strong desire for money and will not buy or sell bitcoin because of the high or low value of the currency."< Recently, Zug, a small Swiss town, announced that from July 1 this year, buyers will be allowed to pay for its public services with bitcoin as the payment method. Although there are still great limitations in the scope and amount of this payment method, the small progress is enough to cheer bitcoin's staunch admirers
from the beginning, virtual goods can only be purchased on the Internet, to now, bitcoin can be converted into multi-national currencies, and there are many twists and turns along the way
in February 2014, Mt. GOx, the world's largest bitcoin trading platform at that time, said that bitcoin was stolen e to large-scale hacker attacks, with a total loss of $470 million, and the platform declared bankruptcy. Affected by this, the price of bitcoin plummeted from more than $600 to $102 in just a few seconds, a drop of 83%
in January 2015, bitstamp, one of the most reliable bitcoin trading platforms in the world, was attacked by hackers, resulting in the theft of at least US $5 million of bitcoin, causing panic among some cryptocurrency holders. The openness and security of bitcoin cause instry concern. When the negative news came out, bitcoin was finally recognized by the regulatory authorities
in September 2015, the US Commodity Futures Trading Commission (CFTC) confirmed for the first time that bitcoin and other virtual currencies are defined as commodities, which means that bitcoin is classified as commodities like gold and oil, and trading behavior will comply with all commodity derivatives market rules; In October of the same year, the European Court of justice formally ruled that bitcoin and other virtual currencies in Europe should be exempt from VAT just like traditional currencies. Because according to the relevant provisions of the EU, "currencies, bank bills and coins used as legal tender" do not need to pay VAT. Bitcoin has taken a solid step towards legalization
nevertheless, the market is still worried about whether bitcoin, which reached a historical peak of more than 8000 yuan in 2013, can return to its former glory
at present, the price of bitcoin is hovering around 2900 yuan, which is much more stable than the previous ups and downs, and the trading volume of bitcoin has also dropped significantly
"I don't think bitcoin has changed from hot to cold. Compared with the sharp rise and overheating in 2013, I think it is now the normal price of bitcoin. In 2013, bitcoin rose from tens of dollars in January to thousands of dollars in less than a year, overdrawing the later increase, so it has been falling back after 2013." Gong Ming told the first financial daily
how much is bitcoin worth? It is estimated that bitcoin players, exchanges, mining machine manufacturers and even bitcoin creators can not give an accurate answer
although the value of bitcoin cannot be determined, one thing is certain that the number of bitcoins is certain. Because the "issuance" of bitcoin depends on complex calculation, it is essentially different from the "printing" mode of traditional currency issuance. The total amount of bitcoin graally increases according to the design predetermined rate, and the increase rate graally slows down, and finally reaches the limit of 21 million in 2140. The instry estimates that the total amount has reached 15.5 million
Li Qiyuan believes that the limited number of bitcoin is in sharp contrast to the inflation and the decline in the purchasing power of fiat money caused by the massive printing of money by central banks“ The goal of bitcoin is not to replace the existing currency, but to become a universal digital asset in the world and provide convenience for people's lives. "
it is generally expected that with the departure of short-term speculators, the continuous development of bitcoin related applications and the improvement of infrastructure, the digital currency represented by bitcoin will be in a benign development stage
in addition to bitcoin, there are also outstanding digital currencies such as lightcoin, Ethereum, dogcoin and Ruitai coin.

One of the biggest characteristics of bitcoin is that it cannot be forged< you can make money in the bitcoin market by investing time and money 
when you spend time on websites, you can visit these websites every few minutes to get a small amount of bitcoin. Therefore, we can do this if we have time. If you want to earn more, you should invest money in the early stage. Bitcoin also has a special casino, so you can earn more by luck
in October 2013, bitcoin Bank of Australia was attacked by hackers, with a loss value of more than US $1 million. This incident has aroused the concern of bitcoin security in Australia.

usually, an attacker uses a stolen account to install the DDoS master program on a computer. At a set time, the master program will communicate with a large number of agents, which have been installed on many computers on the network. When an agent receives an instruction, it launches an attack. Using client / server technology, the main control program can activate hundreds of agents in a few seconds
All statistical data show that the average cost of DDoS attack activities will continue to decline in the near future, while its frequency will continue to increase. It is necessary to learn little knowledge of network security to avoid being attacked
extended data:
precautions for DDoS attack:
1. Require assistance and cooperation with ISPs: it is very important to obtain assistance and cooperation from major Internet service providers (ISPs). Distributed denial of service (DDoS) attacks mainly consume bandwidth, and self-management network alone can not deal with these attacks. Negotiate with ISP to ensure that the other party agrees to help users implement correct routing access control policies to protect bandwidth and internal network
2. Optimize the host of open access: users optimize all possible target hosts. All unnecessary services are prohibited. In addition, multiple IP hosts will increase the difficulty of attackers. It is recommended to use multi IP address technology in multiple hosts, and the home page of these hosts will only automatically turn to the real web server
3. It is very important for users to block attack packets as quickly as possible. At the same time, if they find that these packets come from some ISPs, they should contact each other as soon as possible
