The concept of bitcoin was founded by Nakamoto

On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet

As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty

When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"

Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank

In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the Internet

1. Bitcoin:

also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods

2. The origin of bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. 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. 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 :

the generation principle of bitcoin:

starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

compared with RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you will have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

4. It is a type of virtual bank fraud, similar to Ponzi's fraud, which is the anti body state of pyramid fraud, also known as inverted pyramid fraud. I find Chinese people so stupid. MLM, fundraising, Mars, American land, bit,... How to be fooled next? ha-ha.

5. Hello, there is no weakness of bitcoin. 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

transaction confirmation takes a long time. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless.

grade 5 Qingliangshan should cross the river,

grade 10 Qingliangshan should not cross the river. The river on the left side of the village is mostly

grade 15 is in the mining area, above Lei Dayong<

grade 20 is located in the mining area, where cattle are beaten, Hukou Waterfall grade 20 is located in the mining area,

grade 25 is located in Luliang Mountain,

grade 30 is located in Taiyuan (there are 7 or 8 points concentrated at the entrance of Luliang Mountain to shentouling)

grade 35 is located at the top of LENGKOU city in lujiazhuang,

grade 40 is located at the bottom right of Jinan coachman, as if there are LENGKOU and weijiadian 40 / 45, From lotus root / Wuhan in Tongcheng to Zaozhuang in weijiadian

55 / 60 mines are located in Baiyangding and Shijiazhuang (the lower left corner of 60). There are many 55 mines in Shijiazhuang, and 55 / 60 mines are relatively difficult to dig. When you enter Baiyang from Beiping, you must hang to Fuping, and then enter Baiyangdian and Shijiazhuang. The

65 / 70 mine is in shentouling. It's dangerous to walk along the right side of the entrance. It's better to prepare for store red and battle red. There are less mines in Shanhaiguan, but it's safer. There are more mine liudian from Beiping and Tianjin to Shanhaiguan, Get ready for red

Shanghai seems to have a 90 point

7. What is the essence of bitcoin
A: in essence, it is a multi person account book. But the currency (bitcoin) on the account book is generated out of thin air, and the algorithm is sha256 workload proof

PS: it's learned a lot, involving economics, cryptography, sociology, computer programming, etc. One can't master all of them, so there are many people who don't understand them. When you understand 1 / 2 of what XX learned above, you will understand

What do you think of bitcoin
in the long run (about 20 years), as long as the Internet does not disappear, I think bitcoin and legal currency will coexist for a long time. It will not replace legal currency as some people say, nor will it fall down and disappear as some people say. It is just the big and small difference between BTC circles. In addition, most of the unknowns in five years are not easy to predict. The specific development depends on the attitude of governments. If the attitude is better, the development will happen. If the attitude is not good, for example, the ban, such as Russia, simply say that BTC is illegal. Even so, it will not disappear, but it will go underground and develop little. Within five years, the whole world should get many application support in the enlightened Zhengfu countries, and get better development in the circulation and use in some countries all over the world. The highest price in five years is 20000 yuan. However, it may be as low as 3000 yuan. Be careful of large fluctuations
how to fry bitcoin
if you want to play, Pingtai is the first choice. Pingtai is very important. Otherwise, it will be like volume 796: money running, like mtgo losing: money
let's talk about the fluctuation of bitcoin. Because there is no government to supervise bitcoin, the fluctuation of bitcoin will be much larger, and it will become the extreme investor of bitcoin (not the ordinary investor of bitcoin, generally only playing with futures, goods and stocks)! The bitcoin market could be an IQ game. As a popular sentence in the bar: big money is blood eating! The public and retail investors are always the losers. Therefore, although I support bitcoin, I don't recommend retail investors to "fry" their wealth on bitcoin. Small games are OK. For example, if I lose 1000 yuan, I will make contributions to bitcoin. Here's another thing to say. Not all people who play bitcoin are like bitcoin. People who play bitcoin are looking for the next place to take orders or something. This IQ game has to do according to one's ability. I'm very happy to earn it. It also proves that I have a higher IQ than most people. I can't afford to pay for it. Don't learn how to sell my house, my brother. It's 40000 yuan.

8. Bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system

bitcoin is proced by mining. Mining is the process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary

the total number of bitcoin is 21 million, and more than 1300 points have been mined. Bitcoin was invented by a person or organization named Nakamoto in 2009. At present, Nakamoto has disappeared. He is a mysterious figure. No one knows who he is.
