In the morning of March 9, 2014 Beijing time, Jared Cohen, creative director of Google, said at the Sxsw conference this week that digital cryptocurrency similar to bitcoin will exist for a long time. Cohen and Eric Schmidt, Google's chairman, promoted their co-author book the new digital age at the conference
in the past few months, bitcoin prices have fluctuated significantly. At the same time, this digital currency is strongly supported by the hacker community and is closely related to some black markets. Cohen believes that bitcoin has its value, but it will bring risks if it is not regulated
mt.gox lost $400 million worth of bitcoin, which shakes the confidence of the outside world in bitcoin. Some critics even point out that "bitcoin is dead". However, Cohen's statement is a strong support for cryptocurrency technologies such as bitcoin
bitcoin can exist only because both sides of the transaction recognize its transaction value, so anyone can independently design a virtual currency. Ars technica, for example, announced this week that it would create its own cryptocurrency, arscoin
Cohen believes that the main threat to digital cryptocurrency is how to keep it safely, and the loss of mt.gox bitcoin once again highlights this problem. Recently, the US Congress has also launched a debate on digital cryptocurrency. Some members believe that the supervision of the bitcoin should be strengthened to avoid risks. Another congressman, Jared polis, believes that the US dollar has similar defects to bitcoin, so if bitcoin is banned, then the US dollar note should also be banned
digital currency has a short history in the world, but it develops rapidly. Many countries are trying to sum up experiences and lessons through official or non-governmental efforts
take Europe as an example. In 2015, the transaction volume of digital currency in relevant European countries and regions exceeded 1 billion euro. Although the total amount is not large, it is fierce
it was reported on January 2, 2016 that the Bank of England is also considering whether to issue digital currency by the central bank, and the research work is still in the initial stage. Andy Haldane, chief economist of the Bank of England, said that switching to digital currency would be "a great technological leap forward"
DNB, Norway's largest bank, has already cancelled the cash counter service. The bank called on the government to stop using paper money completely. According to the data, only 6% of Norwegians still use cash every day, most of them the elderly. The social cost of cash payment is twice that of electronic money payment. In one day's life, the payment of bus, shopping, payment, refueling, and even parking is completed by swiping the card. Only when the children's school holds a charity sale can the banknotes be used
compared with paper money, digital currency has obvious advantages, which can not only save the cost of issuance and circulation, but also improve the efficiency of transaction or investment, and enhance the convenience and transparency of economic transaction activities. The issue of digital currency by the central bank also ensures the continuity of financial policy and the integrity of monetary policy, and also ensures the security of monetary transactions
although the issuing method of digital currency is still under study, paper currency has been regarded as "the currency of the previous generation" by some professionals, and it is the general trend to be replaced by new technologies and procts. Due to China's large population and volume, the timetable for issuing digital currency is still uncertain. It is predicted that digital currency and cash will be in parallel and graally replaced for quite a long time. When the era of digital currency really comes, people will carry less and less cash, travel more and more safe, poverty alleviation more and more accurate, corruption more and more difficult to escape, and thieves more and more difficult
historical background
bitcoin is one of the first currencies to realize the concept of "cryptocurrency". In 1998, Wei Dai first expounded the concept of "cryptocurrency" in cypherpunks mailing list. Based on the basic concept of money, which is used to pay for goods, services and debt or any form of records in a given country or economy, bitcoin is a new form of money. Its original design is to integrate the idea of not relying on the central authority, using the principle of cryptography to control the issuance and transaction of money
in 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto claimed that he had transferred to other affairs and left the project. The creator of bitcoin never revealed his true identity, but left his invention to the world. Today, the origin and motivation of the invention of bitcoin is still a mysterious story
since 2010, many developers have devoted themselves to this project, and the bitcoin community has grown rapidly. Between June and July 2011, bitcoin suddenly gained media attention, leading to large-scale buying. The resulting bubble led to the continued decline in the price of bitcoin in the second half of 2011. After that, the price of bitcoin graally rose to the height of 2011
in order to regulate, protect and promote the development of bitcoin, the bitcoin foundation was established on September 27, 2012. Nowadays, with the increasing number of bitcoin users, bitcoin economy is developing rapidly

economic rules
the whole bitcoin network jointly implements the following rules:
the total amount of bitcoin issued is about 21 million

statistics
bitcoin network has been running continuously for more than 48 months. In the past year, bitcoin's security features have attracted attention and developed significantly. As of April 2013:

Many people think that bitcoin is the first digital cryptocurrency in the world, but it is not
In 1982, cryptographer and computer scientist David Chaum proposed a creative scheme blind signature: on a piece of paper, I choose a serial number that only you know, and then I sign it. Because I don't know the serial number, I can't it to another person. This idea forms the first real e-money scheme, which makes anonymous transaction possible
at present, China is experimenting with digital currency, which is legal currency with national credit as guarantee, just like paper money. In the environment of legal digital currency, it will be possible for the economic system to decide the money supply spontaneously and endogenously, issue and recover money automatically through preset and reliable program algorithm rules and on the premise of ensuring the stability of currency value. The role of the central bank may not only be the decision maker of money circulation, but also the designer of the rules of money circulation algorithm
in fact, digital currency is just a form of electronic payment to replace traditional paper money, and the specific application scenario is mobile wallet payment. Digital money is not a virtual currency that can be generated by underground mining and easy to form investment bubbles. Investment in bitcoin and other virtual currencies and electronic money is a Ponzi scheme in a strict sense. The ordinary people need to be careful to avoid leeks. p>
