bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of 
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin

by 2140, the total number of bitcoins was 21 million. I suggest you buy it< In 2009, a mysterious hacker named Satoshi nakomoto first proposed the concept of bitcoin, and described a method of using computer networks to create an unmanaged "secret currency". Unlike other virtual currencies, bitcoin is not issued by a company or a central bank, nor linked to any real currency, but can be used to buy goods and services in the real world. In essence, it can be seen as a small string of encrypted code quickly transmitted and stored in the electronic wallet on the Internet. Just as the P2P networks such as Napster and Skype once made the record instry and telephone instry into a mess, bitcoin, which challenges the modern monetary and financial science, is also based on P2P - the same as our commonly used BT download technology. The advantage of P2P is to ensure that no institution can manipulate the value of bitcoin or increase the supply to create inflation. In a huge P2P network, bitcoin has a special algorithm, which proces about 300 bitcoins per hour. This output is automatically adjusted by the network. Because you can't control most of the network nodes, you can't modify the algorithm of each user to speed up the money proction. Figuratively speaking, bitcoin is "mined" by computers all over the world. If you want to get bitcoin, you just need to install mining software, and your computer will start to do a lot of calculations, which is mining. No matter which computer is used to mine, it is easy to get 50 bitcoins in the early days of bitcoin. As early as January this year, 50 bitcoin was not worth $15, but on June 9, a bitcoin was worth as much as $29.55. If you trade them, you can get back $1500 of real gold and silver. Now, however, mining requires high-performance computers, and some developers involved say that it is estimated that an ordinary laptop will work for five years to get a bitcoin. Why is that? We have to start with the currency itself. Economics tells us that money exists because of transactions. The value of bitcoin lies in the transaction itself. In order to transfer bitcoin from one account to another, there must be a secure channel. To create a secure channel, a lot of energy will be consumed. Therefore, the whole bitcoin user group should reward the mint (50 bitcoin). In other words, he succeeded in mining. Mining, in essence, is the process of creating new blocks (each block contains 50 bitcoin) on P2P network. In short, the software algorithm determines that it is difficult to create a new block that is recognized by the whole network. If there are more participants, the new block will be generated more slowly. Just like mining, with the depletion of the most accessible resources (assuming no newly discovered mineral deposits), the supply will graally decrease. According to the algorithm, each block can only generate 25 bitcoins by 2013, 12.5 bitcoins by 2017, and so on. By 2030, the total number will stay at a platform, about 21 million. Graphically, this will be a flat curve. Reality also proves this point. As the value of bitcoin rises and the number of participants increases, mining becomes more and more difficult. At the forum, miners discussed how to use dry ice and liquid nitrogen to cool computers, increase CPU frequency and speed up mining software, or customize top computer graphics cards and improve network speed to proce more bitcoin. According to the guardian, someone was mysteriously mining at home, and even was suddenly attacked by the police, who mistook him for drug trafficking. Recently, Symantec, a digital security company, discovered a new trojan virus. This malicious program, coinbit, is used to steal numbers, so that hackers can easily break into users' bitcoin wallets and steal their contents. Before the June 19 incident, members of the lulzsec hacker group and anonymous team had discovered that there was a better way to mine - to use someone else's computer. These hacker groups are famous for their server attacks mainly relying on botnets. Some members found that some miners actually use their botnets to mine. The miners are also said to be hackers, who have used botnets to control more than 100000 computers. With the scale of the current network, the efficiency of mining can be greatly improved. It is estimated that 400 to 500 bitcoins can be proced every day, and the current value is more than 8000 US dollars (as of June 28, 2011, 1 bitcoin = 16.9 US dollars). There are two groups of people in the bitcoin community. One group denies that someone is using botnet to mine. The other group says that this is a fact and admits that botnet computing has dropped dramatically. An anonymous person said it was clear that there were people who thought that participation in mining would be more rewarding than attacking mining.
Blockchain concept is so hot! Will blockchain technology become a new outlet
in recent years, the development ecology of blockchain has been graally improved and enriched. Instry insiders believe that with national policy support, extensive attention and financial support, blockchain technology can achieve graal and stable progress. Although the prospect of blockchain technology is broad, we should also keep an ordinary mind
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.
