Bitcoin, the time traveler

1.

It was officially born on January 3, 2009

since 2015, the future of bitcoin has become more and more uncertain. On the one hand, bitcoin fell as much as 55.55% against RMB last year; In 2015, bitcoin fell by more than 30% against the RMB in the first half of January alone

bitcoin's "falling" reflects the "self-healing" of its value after "fanaticism" to a certain extent. According to statistics, in 2013, bitcoin rose from 1 ∶ 13.59 to 1 ∶ 731, with an annual increase of 5300%. This speculative driven inflation has affected the virtual currency property on which bitcoin relies

on the one hand, no country has defined it as a legal currency. On the other hand, in 2014, the US dollar rose significantly, and the prices of oil and bulk commodities fell correspondingly. The price trend of bitcoin is the same as that of the latter, becoming part of the asset allocation of some speculators, which highlights that its asset attribute is far greater than the monetary attribute

extended data

Security and credit risk have also become the reasons for the decline of investor confidence. Mt. GOx, once the world's largest bitcoin exchange, claimed in March last year that it had lost all its assets e to hacker attacks. Recently, it was revealed that its lost bitcoin was probably e to internal system manipulation

the regulatory environment of bitcoin is not optimistic, and Russia, Thailand and other countries have begun to implement strict control on it. In addition, the global stock market performed well last year, resulting in the diversion of bitcoin investment funds, and the crazy "mining" activities also rapidly increased the supply of bitcoin, which may lead to a trend of oversupply in the short term, leading to a sharp drop in the price of bitcoin

2. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system.

Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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 currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. 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

4. Vpay wallet, or Vpay, is a fully open network payment platform. It is almost the same as Alipay or WeChat. The difference is that Vpay is developed on the basis of block chaining technology. It can smoothly achieve point to point cross border transfer without any fee. Mark & Chen, founder of vpay digital assets; Milo Marc Mino, a former technology executive at Google, was born in the United States in 1976 and graated from California State University of technology with a bachelor's degree in physics. From April 2008 to October 2011, I was in charge of Google x Department of Google. From January 2013 to may 2016, I worked as a manager in project ara Department of Google. In 2009, he was awarded the top ten outstanding young people in the United States. In 2012, he won the IEE "outstanding technical achievement award". In 2014, he won the 13th Steve Award for American business. In 2015, he published a research report on cryptography in time, the most authoritative magazine in the United States, which made outstanding contributions to international enterprises and carried out confidentiality work for the U.S. military. In 2016, vpay labs was founded. The technical team carried out optimization on the basis of reborn coin opencoin algorithm, and successfully developed vpay digital assets mining with circulation computing power. In 2017, vpay app was launched to create a new fast, safe and borderless payment tool.

- I specifies the packet capture network card
- s specifies the packet capture length, and only the packet header is captured by default
- W saves the packet capture content, and then it is more convenient to use software such as Wireshark. If you want to scroll through the screen, ignore this option
