Bitcoin protocol analysis software
bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. 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 decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

for a long time, Ethernet has been known as a strong competitor of bitcoin. It wasn't until Andreas antonopoulos claimed that Ethernet was no longer a competitor of bitcoin, which triggered a heated discussion on social networks
people begin to compare the two and discuss the differences in investment and transaction between the two digital currencies< According to Chris burniske, analyst and blockchain proct director of ark investment management company, bitcoin is more used for hedging, while Ethereum, which relies on Ethereum to execute smart contracts, is more seen as a trading tool
bitcoin and Ethereum systems are built on the basis of blockchain, in which transactions are recorded publicly, making currency and asset transactions more convenient and preferential, eliminating the cumbersome middleman
in December 2015, the price of Ethernet currency was less than US $1, but now it has risen to US $15, nearly 15 times in just six months. This achievement is attributed to Ethereum, whose financial contracts are completely executed by software, which has attracted a large number of users to invest
with the previous example of Ethereum, the success of Dao (decentralized autonomous organization) is no surprise. The crowdfunding platform supported by Ethereum raised nearly $150 million from more than 10000 anonymous users. Each participant is given the right to vote, they can allocate funds, choose projects, once the investment project is successful, they can also get a certain degree of dividend reward< There are 670 bitcoin ATMs in the world, and thousands of outlets support bitcoin payment. Unlike bitcoin, Ethereum has not yet emerged in the field of electronic payment. At present, the main purpose of Ethereum is to support Ethereum network (such as Dao) to run programs
David ccini, executive director of the strength in numbers foundation, said:
users' expectations of Ethernet are different from those of bitcoin. Both cryptocurrencies can be used for speculation, but the original function of Ethernet currency is to support the operation of applications. Therefore, users need enough Ethernet coins to run their own app. This is also the problem faced by Dao - unless Dao can continuously generate new Ethernet coins, the payment platform will be in danger of outage.
the system supports sending payments between users without the need to go through a central authority (such as a bank or payment gateway). It is created and saved electronically. Bitcoins are not printed like dollars or euros - they are free software proced and used by computers around the world
Many people think that the reason why bitcoin is valuable is because it is "rare", and if bitcoin is no longer "rare", then it will not have value
this is a misunderstanding. Let's consider a question: what is the essence of all "currencies"
the answer is trust. The biggest reason for the value of the dollar is because of the credibility established for the dollar under the Bretton Woods Agreement, rather than the so-called equivalent exchange with gold (although others say so). The main reason why RMB is valuable is because of the trust system of RMB in China and neighboring countries, rather than the exchange with us dollar reserves (see offshore RMB). This can explain why the currencies of some countries (such as the ruble of Russia, as well as the Zimbabwean currency as you all know) have been greatly devalued, because the government and the current world situation have led to a trust system that does not support the existence of this currency. The so-called economic sanctions and currency speculation are very superficial and superficial reasons
the essence of money is trust
What about bitcoin
bitcoin has no centralized Trust Measurement institution. The value of bitcoin, namely its "credit system", comes from distrust of centralized units. Every country finds that seigniorage is too easy to collect, which leads to the increasingly poor trust between countries. Even the people of all countries do not trust the national currency
and trust, like quality, is conserved. Trust in centralized money decreases, while trust in decentralized money increases naturally
this is the essential reason why the value of bitcoin continues to rise. Therefore, for digital currencies such as bitcoin, there are only two outcomes. Either countries want to understand that they will no longer issue excess currencies, issue additional currencies in a scientific and reasonable way, unify stable exchange rates, and maintain the credit system of centralized currencies, then the value of bitcoin will be infinitely close to zero. Or countries will continue to drink water to quench their thirst, and more frantically use the method of issuing excess currency to collect seigniorage from everyone, then the trust in the centralized currency will be lower and lower, and the total value of bitcoin, a decentralized currency, will be infinitely close to the gross labor value of all the units that do not trust the government and other governments, but need international trade
either the price is crazy or it's worthless
after understanding these, we can answer this question. Will bitcoin be replaced by other digital currencies
swindlers like * * and even the old Wang next door can come and yell, "I spent 10 minutes to change bitcoin's core and create a new digital currency called SBC. Come and join my ICO and pay me seigniorage ~". So, if this happens, will you immediately choose to use Lao Wang's SBC next door
the answer is that some speculators will participate, but the market will not. The reason is very simple, the new cryptocurrency has not been recognized by the market, the application has not been proced, this kind of currency has no way to exchange for means of proction. Then this kind of currency is not money, but a virtual commodity for speculation. In other words, even if old Wang ICO next door has an SBC, no one will choose this kind of currency except those speculators who have no brains
in the current market, there are many other digital currencies, such as Ethereum, EOS, XRP, and so on, which may have technological advantages in some aspects (in fact, BTC has been evolving, and it will also learn from the advanced technologies of other digital currencies that have been successfully proved by the market. LTC and other currencies can be said to be the experimental currencies of BTC's advanced technologies.), There may be more application scenarios than BTC in the future, but they are not likely to challenge the status of BTC. BTC will always be the first consensus in the currency circle, which is the belief of many people. BTC will exist for a long time as the gold in the currency market, not mainly for the circulation of digital currency
but there is no problem, so it can not be determined
few investors and poor liquidity; Lack of supervision and serious manipulation.
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
