Unlike most currencies, Bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations according to a specific algorithm. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transaction behaviors, and uses cryptography to ensure the security of all aspects of currency circulation. The decentralized nature of P2P and the algorithm itself can ensure that the currency can not be manipulated artificially and create a large number of bitcoins. The design based on cryptography can make bitcoin only transferred or paid by the real owner. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that its total amount is very limited and extremely scarce. The monetary system once did not exceed1050,000 for four years, and the total will be permanently limited to 21050,000.
Bitcoin can be cashed and converted into the currencies of most countries. Users can use Bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use Bitcoin to buy real-life items. [ 1][2]
On February 26th, 20 14, Senator Joe Manchin, Democrat of West Virginia, sent an open letter to several regulatory departments of the US federal government, hoping that the relevant departments could pay attention to the current situation that Bitcoin encourages illegal activities and disrupts the financial order, and demanded that action be taken as soon as possible to completely ban the electronic money.

When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Satoshi Nakamoto" and described the model of Bitcoin.

bitcoin
Compared with legal tender, Bitcoin has no centralized issuer, but is generated through the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, which can be circulated all over the world. It can be bought and sold on any networked computer. No matter where you are, anyone can mine, buy, sell or collect bitcoin, and foreigners can't identify the user identity information during the transaction. [2] In 2009, Bitcoin, which is not controlled by the central bank or any financial institution, was born. [2] Bitcoin is an "electronic currency", which consists of a series of complex codes generated by a computer. The new bitcoin is made by a preset program. With the increase of the total amount of bitcoins, the speed of making new coins slowed down, until it reached the upper limit of 265,438+00,000 in 2065,438+04, and the total number of bitcoins dug up has exceeded 654,380+02,000. [2]
Whenever Bitcoin enters the mainstream media's field of vision, the mainstream media always invites some mainstream economists to analyze Bitcoin. Previously, these analyses always focused on whether Bitcoin was a scam. The current analysis always focuses on whether Bitcoin can become the mainstream currency in the future. The focus of this debate often focuses on the deflationary characteristics of Bitcoin. [5]
Many bitcoin players are attracted by the fact that bitcoin cannot be issued at will. Contrary to the attitude of bitcoin players, economists hold a polarized attitude towards the fixed amount of 2 1 10,000 bitcoin. [6]
Keynesian economists believe that the government should actively regulate the total amount of money and use the tightness of monetary policy to refuel or brake the economy at an appropriate time. Therefore, they believe that bitcoin's fixed monetary aggregate sacrifices controllability, and worse, it will inevitably lead to deflation, thus hurting the overall economy. Economists of the Austrian school hold the opposite view. They think that the less government intervention in the currency, the better. Deflation caused by fixed monetary aggregate is not a major event, even a sign of social progress.
Bitcoin network generates new bitcoins by "mining". The so-called "mining" is essentially to solve a complex mathematical problem with a computer to ensure the consistency of the distributed accounting system of Bitcoin network. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer every 10 minute. Then the bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer.
When Bitcoin was born in 2009, each prize was 50 bitcoins. After the birth of 10 minutes, the first batch of 50 bitcoins were produced, and the total amount of money at this time was 50. Subsequently, the number of bitcoins increased by about 50 per 10 minute. When the total amount reaches 6.5438+005 million (50% of 26.5438+000 million), the reward will be halved to 25. When the total amount reaches15.75 million (the new output is 5.25 million, that is, 50% of 1050), the reward will be halved to 12.5. [7]
First of all, according to its design principle, the total amount of bitcoin will continue to grow until it reaches 2 1 10,000 years later. However, the growth rate of the total amount of bitcoin money will be very slow in the later period. In fact, 87.5% of Bitcoin will be "dug up" in the first 12 years. Therefore, from the perspective of the total amount of money, Bitcoin will not reach a fixed amount. In essence, its total amount of money will continue to expand, although the speed is getting slower and slower. So it seems that Bitcoin is an inflationary currency.
But judging deflation or inflation is not based on whether the total amount of money is decreasing or increasing, but on whether the overall price level is decreasing or increasing. The overall price increase is inflation, and vice versa is deflation. In the long run, the issuing mechanism of Bitcoin determines that the growth rate of its total currency will be much lower than the growth rate of social wealth.
Keynesian economists believe that falling prices will make people tend to delay consumption because the same dollar can buy more things tomorrow. The reduction of consumption will further lead to shrinking demand, unsalable goods, lower prices and a vicious circle of "deflation spiral". Similarly, deflationary money can appreciate even if it is not deposited in the bank itself (purchasing power is getting stronger and stronger), people's willingness to invest will also increase, and social production will fall into a downturn. [5] Therefore, Bitcoin is a currency with deflation tendency. In the bitcoin economy, the prices of goods priced with bitcoin will continue to fall. [ 1]
Bitcoin is a kind of online virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currencies of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use Bitcoin to buy real-life items. [ 1][ 1]
2065438+On September 9th, 2004, Yi Bei, an American e-commerce giant, announced that its payment processing subsidiary Braintree would start accepting bitcoin payments. The company has reached a cooperation with Bitcoin base, a bitcoin trading platform, and started to accept this relatively new payment method.
Although Yi Bei's market trading platform and PayPal business do not accept bitcoin payment, Braintree customers such as travel rental community Airbnb and car rental service company Uber will begin to accept this virtual currency. Braintree's main business is to provide payment processing software for enterprises. The company was acquired by Yi Bei for about $800 million last year.
2065438+071October 22nd night, Huobi. Com, btc China and OKCoin have successively announced in their respective official website that in order to further curb speculation and prevent sharp price fluctuations, all platforms will start charging transaction service fees from noon on 20 17124/0/2: 00. [4] On May 5th, the latest data of OKCoin showed that the price of bitcoin had just set a new record, reaching a high of 9222 points before the deadline. [8]
The founder listens to the voice.
On June 1 65438+1October1day, 2008, a man who claimed to be Satoshi Nakamoto posted a discussion statement on a secret cryptography commentary group, stating his new idea of electronic money-the advent of Bitcoin and the completion of the first transaction of Bitcoin. By revealing and distributing the general ledger, Bitcoin got rid of the constraints of third-party organizations, which Satoshi Nakamoto called "regional chain". Users are willing to dedicate the computing power of CPU and run a special software as a "digger", which will form a network and maintain a "regional chain". In the process, they will also generate new money. Transactions also extend on this network, and the computer running this software really solves the irreversible password problem, which contains several transaction data. The first "miner" to deal with the problem will receive a reward of 50 bitcoin, and the relevant trading area will join the chain. With the increase of the number of "miners", the difficulty of each puzzle has also increased, keeping the bitcoin productivity of each trading area at around 10 minutes.
Shinichi Mochizuki, a professor of mathematics at Kyoto University, said.
In 2009, Satoshi Nakamoto designed a digital currency, namely Bitcoin. The bitcoin market is ups and downs, and the identity of its founder "Satoshi Nakamoto" has always been a mystery. The rumor about "the father of Bitcoin" involves people from the National Security Agency to financial experts, and also casts a mysterious aura on Bitcoin.
According to foreign media reports, computer scientist TedNelson posted a video on the Internet on Sunday, saying that he had confirmed that the founder of Bitcoin was ShinichiMochizuki, a professor of mathematics at Kyoto University. The founder of Bitcoin has always used the pseudonym of SatoshiNakamoto, and there have been many speculations about its true identity in the Internet field. Nelson released a video saying that he had identified Shinichi Mochizuki as the real founder of Bitcoin. [9]
The new moon 20 13 became famous for proving ABC conjecture. In high school, he attended Philip Exeter College, one of the most prestigious high schools in the United States, and graduated two years later. Shinichi Mochizuki/Kloc-entered Princeton University at the age of 0/6, left as a doctor at the age of 22, and became a full professor at the age of 33. It is extremely rare for him to get the title of full professor at such a young age in academic circles. This superstar in mathematics may have solved one of the most important problems in this field.
Satoshi Nakamoto himself left little personal information on the Internet, especially in recent years, which almost disappeared completely, so his life experience became a mystery. On March 7th, 20 14, the news that the founder of Bitcoin, Dorian P. Satoshi Nakamoto, was found quickly became the most attractive news on the Internet.
Contrary to speculation that it may be a pseudonym, "Satoshi Nakamoto" is a real name. He is a 64-year-old Japanese American. He likes collecting model trains. I have worked in large enterprises and the US military, and engaged in confidentiality work. In the past 40 years, Satoshi Nakamoto has never used his real name in his life. According to the file of Los Angeles District Court 1973, when he graduated from California State Polytechnic University at the age of 23, he changed his name to DorianPrenticeSatoshiNakamoto. From then on, he no longer used the name "Cong", but Dorians (Dorians. Satoshi Nakamoto) as his signature. [9]
The production principle of listening to speech
From the essence of Bitcoin, the essence of Bitcoin is actually a special solution generated by a bunch of complex algorithms. Special solution refers to a set of infinite (in fact, bitcoin is limited) solutions that can be obtained through an equation group. And each special solution can solve the equation, which is unique. [10] Taking RMB as a metaphor, Bitcoin is the serial number of RMB. If you know the serial number on a bill, you will have this bill. The process of mining is to constantly seek the special solution of this equation group through huge calculation. This set of equations is designed to have only 2 1 million special solutions, so the upper limit of bitcoin is 2 1 million. [ 10]
Crazy rise
To exploit bitcoin, you can download a special bitcoin computing tool, then register various cooperation websites, fill in the registered user name and password in the computing program, and then click the operation to officially start. [1 1] After installing the bitcoin client, you can directly obtain a bitcoin address. When someone pays, you only need to post your address to others, and you can pay through the same client. After installing the Bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing the private key to ensure that your property will not be lost. If the hard disk is unfortunately completely formatted, personal bitcoin will be completely lost.
The monetary characteristics of listening to sounds
Decentralization: Bitcoin is the first distributed virtual currency, and the whole network consists of users without a central bank. Decentralization is the guarantee of bitcoin security and freedom.
Global circulation: Bitcoin can be managed on any networked computer. No matter where you are, anyone can mine, buy, sell or collect bitcoin.
Exclusive ownership: manipulating bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the users themselves.
Low transaction cost: Bitcoin can be remitted for free, but in the end, a transaction fee of about 1 bit will be charged for each transaction to ensure the faster execution of the transaction.
No hidden cost: Bitcoin, as a means of payment from A to B, has no complicated quota and procedures. You can pay by knowing the other party's bitcoin address.
Cross-platform mining: Users can explore the computing power of different hardware on many platforms.
superiority
Completely decentralized, without issuers, it is impossible to manipulate the number of issues. Its distribution and circulation are realized by open source p2p algorithm.
Anonymous, tax-free and supervision-free.
Robustness Bitcoin relies entirely on p2p network, and there is no distribution center, so it cannot be closed to the outside world. Bitcoin prices may fluctuate and collapse, and many governments may declare it illegal, but Bitcoin and its huge p2p network will not disappear.
Borderless, cross-border Cross-border remittances will go through layers of foreign exchange control institutions, and transaction records will be recorded by many parties. But if you use bitcoin to trade, you can directly enter the digital address, click the mouse and wait for the p2p network to confirm the transaction, and a lot of money will pass. Without going through any regulatory agencies, no cross-border transaction records will be left.
It is difficult for people in shanzhai to survive. Since the Bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile and create a new p2p currency. However, these counterfeit coins are very fragile and vulnerable to 5 1% attacks. Any individual or organization, as long as it controls the computing power of 5 1% of a p2p coin network, can manipulate the transaction and currency value at will, causing a devastating blow to p2p coins. A lot of counterfeit money died in this link. The bitcoin network is robust enough, and the number of cpu/gpu needed to control the computing power of 5 1% of the bitcoin network will be astronomical.
disadvantaged
Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. The trading platform is generally a website, which will be attacked by hackers or shut down by the competent authorities.
The transaction confirmation time is long. When the Bitcoin wallet was first installed, it would take a lot of time to download historical transaction data blocks. When trading bitcoin, in order to confirm the accuracy of the data, it takes a certain amount of time to interact with the p2p network, and the transaction is completed after the confirmation of the whole network.
The price fluctuates greatly. Due to the involvement of a large number of speculators, the price of bitcoin for cash has fluctuated like a roller coaster. Make Bitcoin more suitable for speculation rather than anonymous trading.
The public does not understand the principle and the resistance of traditional financial practitioners. Active netizens understand the principle of p2p network and know that Bitcoin cannot be manipulated and controlled artificially. But the public doesn't understand that many people can't even tell the difference between Bitcoin and Q coins. "No issuer" is the advantage of Bitcoin, but in the eyes of traditional financial practitioners, the currency without issuer is worthless. [ 12]
Listen to the voice of currency trading
Coiling method
Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to algorithms to "mine" bitcoin. When users "mine" bitcoin, they only need to search for 64-digit numbers through the computer, and then compete with other gold diggers by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, they will get 25 bitcoins.
Because the Bitcoin system adopts decentralized programming, only 25 bitcoins can be obtained every 10 minute, and by 2 140, the upper limit of bitcoins in circulation will reach 210 million. In other words, the bitcoin system can be self-sufficient, coded to fight inflation and prevent others from destroying these codes.
Trading means
Bitcoin is electronic cash similar to e-mail. Both parties need a "Bitcoin wallet" similar to e-mail and a "Bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the sender pays bitcoin directly to the other party through a computer or smart phone according to the address of the recipient. The following table lists some websites that download bitcoin wallets and addresses for free.
Bitcoin address is a string of letters and numbers about 33 bits long, always starting with 1 or 3, for example, "1dwuna9otzzqyhvkj8dv1tuswmf7r3v". Bitcoin software can automatically generate addresses, which can be done offline without exchanging information online [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in every grain of sand, the total number of bitcoin addresses far exceeds the number of all sands on all these "earths".
Bitcoin address and private key appear in pairs, and their relationship is like bank card number and password. A bitcoin address is like a bank card number, which records how many bitcoins you have at that address. You can randomly generate a bitcoin address to store bitcoin. Every time a bitcoin address is generated, the private key corresponding to the address will be generated. This private key can prove your ownership of the bitcoin at this address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password corresponding to the bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, when using a bitcoin wallet, please keep your address and private key safe.
After the transaction data of Bitcoin is packaged into "data blocks" or "blocks", the transaction is initially confirmed. When the block is linked to the previous block, the transaction will be further confirmed. After six consecutive confirmations, the transaction is basically confirmed to be irreversible. Bitcoin peer-to-peer network stores all transaction history in a "blockchain". The blockchain continues to expand, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a group of scattered client nodes, a distributed database composed of all participants, and a record of all bitcoin transaction history. Satoshi Nakamoto predicted that when the amount of data increases, clients hope that not all the data is stored on their own nodes. In order to achieve this goal, he adopted the mechanism of introducing hash function. In this way, the client will be able to automatically eliminate those parts that will never be used, such as some very early bitcoin transaction records.
consumption pattern
Many websites for technology players have begun to accept bitcoin transactions. Including websites such as Mtgox and BTCChina, as well as some stores in Taobao, and even accept services such as exchanging bitcoin for dollars and euros. There is no doubt that Bitcoin has become a real currency in circulation, not a virtual currency like Tencent Q coins. There are specialized third-party payment companies abroad, similar to Alipay in China, which can provide API interface services.
You can buy bitcoin with money, or you can be a miner and use a computer to search for 64-digit "mining". By repeatedly decrypting with a computer, we can compete with other gold diggers to provide the required numbers for the Bitcoin network. If the computer can successfully create a set of numbers, it will get 25 bitcoins. Bitcoin is decentralized. A fixed number of bitcoins need to be created per unit of computing time, and 25 bitcoins can be obtained every 10 minute. By 2 140 years, the upper limit of bitcoin in circulation will reach 2 1 10,000. In other words, the bitcoin system is self-sufficient, and translating it into code can resist inflation and prevent others from destroying it.
Payment case
While being chased by investors, Bitcoin has been accepted by individual businesses in reality. A restaurant in Beijing started bitcoin payment. The restaurant located in Chaoyang Joy City said that it will accept bitcoin payment at the end of 20 1 13. At the end of the meal, consumers can transfer a certain amount of bitcoin to the store account to complete the payment. The whole process is similar to bank transfer. The restaurant once settled a meal in 650 yuan with 0. 13 bitcoin. [ 13]
In October, 2065438+200465438+/kloc-0, Overstock began to accept Bitcoin, becoming the first large-scale online retailer to accept Bitcoin. [ 14]
Bitcoin was created by Satoshi Nakamoto and is (almost certainly) an alias. So far, no one has been able to accurately associate Bitcoin with a real person or a group of people. Satoshi Nakamoto disappeared from the Internet on 20 1 1, leaving almost no clue who they might be. Over the years, many people have publicly claimed to be Satoshi, but they have not supported this statement with indisputable facts.
At an early Bitcoin forum, Satoshi said that they started to study Bitcoin in 2007, two years before the first block mining. On June 38, 2009+10/October 3, 2009, the first block of Bitcoin blockchain, Genesis Block, was mined. Satoshi Nakamoto, a miner at Genesis Block, received the first batch of 50 bitcoins. But the reward of the first box can't be paid, because the expression of Genesis box in the code is a bit strange. BitMEX Research published an analysis of the early use of bitcoin and concluded that "someone" used 700,000 bitcoins. Although many people think it is Satoshi, the official has not confirmed it.
People can only imagine what kind of reputation Satoshi Nakamoto will gain if their identities are exposed, not to mention the huge wealth they will collect (although Sato doesn't seem to have spent any coins they should dig). Over time, many people claimed to be Satoshi, while others were forced to do so.
Unfounded creditor's rights
One of the most famous examples of self-proclaimed Cong is Satoshi Nakamoto, an Australian scholar. As early as 20 15, Wright tried many times to show the public irrefutable evidence that he was the inventor of bitcoin, but he didn't succeed until today. In fact, his "evidence" proved to be forged.
Why must Satoshi remain anonymous?
Satoshi Nakamoto, the first creator of decentralized currency in the world, should remain anonymous because of the nature of his creation. After creating a protocol without a failure center, Satoshi Nakamoto may have realized that remaining anonymous may eliminate the last possible failure center of Bitcoin: the person who created it. Removing a single identity that may be associated with the emergence of Bitcoin removes any single face that may affect the politics, rules or decisions of the Bitcoin community.
No matter who Cong is, they are undoubtedly the geniuses of our time. The Bitcoin agreement provides economic incentives in all appropriate places and provides special solutions to the problems of Byzantine generals. Satoshi Nakamoto used the concepts of cryptography, mathematics, game theory and economics to create a beautifully designed digital scarce asset-Bitcoin.
The inventor of Bitcoin is a Japanese named Satoshi Nakamoto. On June 3rd, 2009, the world's first batch of Bitcoin was born, and digital currency was officially born. The price of digital currency did not rise rapidly until the end of 20 13, rising from about 10 in the previous period to more than 900 dollars. In 20 16 years, the popularity of bitcoin really rose. Why is Bitcoin so valuable?
1. Mining is very difficult. Bitcoin mining requires specific operations and requires a lot of time and material resources in the early stage.
2. Bitcoin has currency attributes and is trusted by the market. The encryption algorithm of Bitcoin is difficult to crack, which ensures its uniqueness.
3. The bitcoin trading market is highly transparent and the market prices are open and transparent. The flow and transaction of virtual digital goods are convenient and fast.
4. With the recognition of some countries, some policies issued by digital currency will undoubtedly stimulate the price increase of Bitcoin.
Things are scarce, bitcoin is relatively scarce, and the mining of comparative coins is very difficult at present. The influence of supply and demand and the shortage of market supply have undoubtedly played a great role in the price increase. Be cautious about friends who buy bitcoin on the trading platform to earn the difference.
Bitcoin is a P2P digital currency. Point-to-point transmission means a decentralized payment system. In 2009, Japanese Satoshi Nakamoto put forward the concept of Bitcoin. Since its birth, the price of Bitcoin has been unimaginable. Why is Bitcoin so valuable?
Say it briefly.
By running a special program, the bitcoin mining machine can get bitcoin with similar task rewards after running. At present, the output of bitcoin is very low, about 3600 new coins are produced every day, and the number is limited; Bitcoin mining is expensive. Since the popularity of Bitcoin, the price of professional mining machines has been around 10,000 yuan, and now the price is more than 300,000 yuan. The early equipment investment requires a lot of financial resources. Mining takes a long time. Bitcoin mining is a specific complex operation, which takes a long time; In addition to its own losses, bitcoin mining machines also consume a lot of electricity. The daily power consumption of bitcoin mining machine can reach 65.438+88 billion kWh, which is equivalent to 1% of the daily power generation in China. The number of bitcoins is still increasing. According to the agency's assessment, in 20 19, the power consumption of bitcoin mining will exceed that of the United States.
The price of bitcoin has always been related to the media. I would like to remind everyone here that the price of Bitcoin is rising fast, and the destination will be fast and risky. Friends who want to buy bitcoin to make money must join carefully.
Bitcoin, which has been silent for many days, has made a comeback with the "blackmail" virus and started the familiar runaway mode. This virtual currency, known as "digital gold", has soared 3 million times in eight years, and even Chinese aunts have entered the market. Some people think that this is a parcel-passing game, some people firmly believe that Bitcoin will become a scarce asset, and some even say that it will be a shining node in the long river of history, and most people are not seeking solutions, but just marveling at another round of wealth explosion.
Who does Airbnb think created Bitcoin? There has been no conclusion about the inventor of Bitcoin, and it is generally said that the Japanese are "Satoshi Nakamoto". On June 3rd, 2009, the first batch of bitcoin in the world was "dug up", and this digital currency designed by a man code-named "Satoshi Nakamoto" was officially born. After that, 15 people were suspected to be "Satoshi Nakamoto". In 20 14, the authoritative American media revealed that the Japanese-American physicist whose real name was "Satoshi Nakamoto" was the legendary "father of Bitcoin", but the old professor firmly denied it. The picture shows Satoshi Nakamoto, who rarely shows up, being besieged by the media, constantly blocking the camera and denying any connection with Bitcoin.
20/kloc-in may, 2006, Satoshi Nakamoto, an Australian engineer and entrepreneur, publicly stated that he was the creator of bitcoin-Satoshi Nakamoto. But just a few days later, White himself "surrendered" and issued an apology letter, saying that he "could not produce key evidence" to prove himself. Although Satoshi Nakamoto was nominated as a candidate for the Nobel Prize in Economics in 20 16, his real veil has not been completely unveiled. Image: BBC (from: Tencent Image)
Craig White was targeted by the police after being related to Bitcoin. The picture shows Australian federal police and tax officials searching White's residence and office, whose bitcoin-related business has tax problems. According to media reports, the mysterious figure "Satoshi Nakamoto" holds more than/kloc-0.0 million bitcoins. According to the current price of 15000 RMB, his value exceeds1500 million RMB. According to the original strict design, the total amount of bitcoin was limited to 2 1 10,000 pieces, and about10.4 million pieces have been mined at present. Photo: Reuters.
Satoshi Nakamoto, I don't know who he really is.
