What studio is bitcoin
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
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. 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 currency circulation
extended data:
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
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
the bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
the P2P network structure adopted by bitcoin is not just the choice of topology. Bitcoin is designed as a point-to-point digital cash system, and its network architecture is the reflection and cornerstone of this core feature. Decentralized control is the core principle of design, which can only be achieved by maintaining a flat and decentralized P2P consensus network
each node in bitcoin P2P network is peer-to-peer, but according to the different functions provided, the division of labor of each node is not the same. Each bitcoin node is a functional set of routing, blockchain database, mining and wallet services. A bitcoin network node includes four functions: wallet, miner, complete blockchain and network routing node
some nodes keep a complete and up-to-date of the blockchain, which is called "all nodes". The whole node can independently verify all transactions without any external reference. In addition, some nodes only retain part of the blockchain, and they complete transaction verification through a method called "simple payment verification (SPV)". Such a node is called "SPV node", also known as "lightweight node"
mining nodes create new blocks in a competitive way through proof of work (POW) algorithm running on special hardware devices. Some mining nodes are also full nodes, keeping a complete of the blockchain; There are also some nodes involved in the mining of the mine pool, which are lightweight nodes, and they must rely on the whole node maintained by the mine pool server to work
User wallets can also be used as part of the whole node, which is common in desktop bitcoin clients. At present, more and more users' wallets are SPV nodes, especially bitcoin wallets running on resource constrained devices such as smart phones, which is becoming more and more common.
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

bitcoin is the first currency to realize the concept of "secret currency". In 1998, Wei Dai first expounded the concept of "secret currency" in cypherpanks mailing list, that is, a new form of currency that uses cryptography principles to control the issuance and transaction of currency, rather than relying on the central management organization. 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 left the project and did not disclose much about his identity. Since then, many developers have devoted themselves to bitcoin projects, and the bitcoin community has grown rapidly.
The title of architecture is reviewed by the local labor and personnel department on a regular basis. It can be applied by itself and declared by the unit. The local labor and personnel department will review and publicize it
technical positions can be divided into junior, intermediate and senior positions. Generally, the first step is to declare from the junior level, which can be divided into technician and assistant engineer; Middle level is engineer; The senior engineer can be divided into deputy senior engineer and senior engineer, and the professional title evaluation needs to provide proof of identity, graation certificate, resume, professional thesis, computer and foreign language level examination
In addition to the professional examination, the examination of computer and foreign language should also be carried out. Professional title computer has been one of the conditions for evaluating professional titles since 2002, while professional title foreign language has been one of the examinations for promoting professional posts since 1999

Bitcoin trading platform undertakes most of the functions of "bitcoin for cash" and "cash for bitcoin". The three largest exchange platforms in the world are Mt. GOx, bitstamp and btcchina. If you think that the use of bitcoin wallet is too cumbersome, the transaction data block takes up too much space. You can also use the trading platform as an online wallet. But note that bitcoin in the trading platform is actually stored on the website server
the total number of bitcoin trading platforms at home and abroad is about 100000 BTC. The daily turnover of bitcoin trading platform in normal operation in China is about 50000 BTC. But trading volume doesn't mean bitcoin usage. Speculators keep buying and selling bitcoin in the trading platform, which makes the trading volume of bitcoin far larger than the turnover among users; Even less bitcoin is used for payment
there are many online bitcoin trading institutions at home and abroad, which accept the exchange of bitcoin and legal tender. Mt. GOx is the earliest bitcoin trading platform, which was established in Japan in 2010. Bitstamp and btc-e are two other foreign trading platforms. There are also a large number of trading platforms in China
anyone can set up a bitcoin trading platform and develop a trading platform, which is no different from the development of traditional websites. And open source website has ready-made PHP class library can be called. Any bitcoin trading platform will become a live target for hackers. Can we guarantee the security of the website? If the website is attacked by hackers and all the bitcoin stored on the server is taken away, how to explain to the registered users? Mt. GOx, headquartered in Japan, used to be the largest bitcoin trading platform. On February 25, 2014, the official website of mt.gox was blank. Mt. GOx has deleted all of its twitter posts
on February 25, 2014, a number of bitcoin trading platforms including coinbase, circle and "bitcoin China" jointly issued a statement, which defined the incident as "the ruthless betrayal of mt.gox users' trust is caused by the ugly behavior of a company"
these companies said: "in order to solve the trust crisis caused by the failure of mt.gox, the responsible bitcoin trading platform will work together to promote the future of bitcoin and ensure the capital security of all customers. On February 25, 2014, the opening price of "bitcoin China" was 3562.41 yuan. By 4:40 p.m., the price had dropped to 3185 yuan, down more than 10%
according to the historical market data of the platform, on January 27, 2014, 1 bitcoin could be converted into 5032 yuan RMB. This means that in less than a month on the platform, the price of bitcoin has dropped by 36.7%. At the end of October 2013, Hong Kong GBL platform absconded with funds, and the whereabouts of more than 20 million yuan of funds were unknown. The program of this trading website is very poor. It doesn't use SSL security protocol, and even the user name is stored in clear text. They don't have some basic programming knowledge. GBL relies on the broker to develop the new customer's "quasi MLM" mode
on October 22, 2013, looking at the market of bitcoin, Mr. Qiao, a citizen of Dongyang, searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, 2013, it was found that the staff of the online trading platform were not online, and some normal trading proceres could not be implemented. It was found that the registered address of the company was false after a check, and a total of 90000 yuan was cheated. This is the first case of "bitcoin" fraud in Dongyang City. The police remind the citizens who buy "bitcoin" on the Internet to pay attention to screening the authenticity of the website to prevent being cheated
western economists have a lot of worries about the current economic bubble phenomenon of bitcoin. Australian Economist John Quiggin called bitcoin as "the most pure example of economic bubble (perhaps the finest example of a pure bubble)" recently, bitcoin continues to be hot, so that the virus, Trojan horse active, anti-virus company said, January and bitcoin mining related Trojan horse variants of ten thousand. In addition, some netizens disclosed to the IT channel of chinanews.com that some counterfeit coins similar to bitcoin may have "special blocks" and be poached. For ordinary miners, this may be more terrible than a Trojan horse
a bitcoin blackmail virus named "CTB Locker" is spreading in China. The virus can extort ransom from users by encrypting their computer files remotely. Users' files can only be opened after paying ransom
according to anti-virus experts, the virus cannot be cracked at home and abroad. On May 27, 2014, through the analysis of transaction data, Willy report website came to the conclusion that the soaring price of bitcoin last year and the huge increase in the trading volume of Mt. GOx may be e to false transactions, and may even involve insiders of Mt. GOx
nowadays, more and more people begin to suspect that the sharp rise of bitcoin in November 2013 and the increase of mt.gox's trading volume are partly e to a fraud. Specifically, a robot called "Willy" buys five to 10 bitcoins every five to 10 minutes, and this behavior lasts for at least a month
the bitcoin price of mt.gox has soared from about $200 in early November 2013 to a record high of $1236 on December 4 last year. While making early participants excited, more and more analysts began to explore the reasons behind: is it because Chinese people are speculating in their free exchanges? Or is it because bitcoin's resistance to government confiscation after the "Silk Road incident" led to a large outflow of this virtual currency
Willy report is a website with only one article, which describes in detail all kinds of suspicious robot trading activities from September to November 2013
I have noticed bitcoin since 2010,
from 2013 to 2015,
when blockchain technology began to develop
