Popular explanation of bitcoin

1.

The earliest is a kind of network virtual currency. 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. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar

< H2 > extended information:

bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address

starting from the essence of bitcoin, the essence of bitcoin is actually a 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

many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin

2. Let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

3. I will analyze my personal cognition of the value of comparative currency from two perspectives:
1. A little thought on currency
at present, the currency issued by all countries in the world is basically credit currency. For example, the US dollar has been decoupled from gold since the Bretton Woods system. It is generally believed that the value of the modern dollar is supported by the national credit, or national strength and military strength of the United States
however, this is specious. Because the national strength and military strength of the United States cannot be quantified, who can tell me how much the national strength and military strength of the United States are worth? Since it is impossible to quantify, how can we ensure that the US dollar is not printed too much? In fact, there is no guarantee. On the other hand, it says "in God we trust" on the dollar, which is to tell you clearly that the dollar is actually a kind of faith. It's like trump supporters shouting, "America! USA! ", People's trust in the dollar is not purely rational, but a mixture of rationality, pride, sacredness, speciousness and habitual thinking
and this kind of trust is also fragile. In recent years, for example, the Thai baht and ruble have dropped by 40% or 50% overnight, which is also common. Even more outrageous, for example, the government of the Republic of China basically cheated on the golden yuan
bitcoin is also true. Its value comes from trust, but it is not backed by the government's credit endorsement. The letter of bitcoin is a more pure letter, because it is more invisible than the legal coin, but there is a small group of people who believe in it, such as me. This kind of letter comes from the simplicity and strength of bitcoin technology, from the ideas beyond the times contained in it, from the dissatisfaction with the existing monetary system, and from the natural yearning for progress of human beings
2. Bitcoin price and reflexivity
Buffett's value investment theory is very popular: because of people's fear or greed, the price of a thing may temporarily be higher or lower than its value, but it will eventually return to the value itself
Soros's view is that because of the fragility of human nature, a thing can never return to its value. That is to say, the correction must be over correct. When the value of a thing is absolutely undervalued, then in the process of rising, people's awareness of its rising is constantly strengthened, which often leads to crazy buying, and the final price will rise to its own value, and vice versa
in this process, the rise of price leads to people's pursuit of a thing, and people's rising expectation will continue to push up the price of this thing
Soros calls it reflexivity
for example, there is a prophet in the village. He told us that gold would go up and we should go to buy gold. Everyone flocked to buy gold. The supply of gold was in short supply, and it rose as expected. So everyone said that the prophet was right
this process has nothing to do with the basic value of gold or the actual demand for gold
if you look at it with a magnifying glass. In this process, the bullish view of gold is constantly strengthened. Because gold also rose in the process. If in the first rise callback, someone sold. When it goes higher for the second time, this person will feel that his operation is particularly stupid, so he will not easily sell when he buys again next time. Even if he sells again next time, there will always be a time when he will "learn to be smart" and no longer sell
man is also a social animal. So this expectation of rising will continue to spread and "learn" from each other, aggravating this weakness of human nature
often when a bubble burst, most people could not escape. A few rational people can run away, a few win the majority and make a lot of money. In the book mob, it is said that the IQ of a group is often lower than that of a person. In management, this is called herding. In China's stock market, this is called "retail dividend". You don't see how many people earn money every day on the platform, even wealth is free.

Bitcoin is a kind of electronic cryptocurrency based on blockchain, which is decentralized, global, and does not need third-party institutions or indivials. Bitcoin was invented and founded by Nakamoto (pseudonym) on January 3, 2009, based on the peer-to-peer network without borders, using consensus initiative open source software. It is the ancestor of cryptocurrency and blockchain, and is also the cryptocurrency with the highest popularity and market value at present

generally speaking, bitcoin is a digital currency with a total amount of 21 million, which has the characteristics of decentralization, globalization, anonymity and so on, just like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields

{rrrrrrr}

extended materials:

the global financial crisis broke out in 2008. On November 1, 2008, a person who called himself Nakamoto published bitcoin white paper "bitcoin: a peer-to-peer e-cash system" on the P2P foundation website, stating his new idea of e-currency bitcoin. On January 3, 2009, bitcoin Genesis block was born

compared with fiat money, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or collect bitcoin, And in the transaction process, foreigners can not identify the user's identity information

as a standardized, globalized, highly volatile, 24-hour and never-ending trading target, bitcoin is more volatile than stocks, foreign exchange, precious metals and other electronic disk targets; In terms of standardized trading, soaring history and future prospects, it is better than the physical speculation targets such as stamps and coins, garlic, Pu'er tea and Huangli wood, so it has attracted a lot of hot money to participate in the speculation

at present, the funds attracted by bitcoin as the target of speculation far exceed the funds attracted by the payment system. At least half of the price of each yuan is the value of the target of speculation

6. Bitcoin is a kind of electronic currency generated by complex algorithm

by analogy
ordinary currency is printed by the mint
bitcoin is calculated by the computer
the advantage is that the total number of bitcoin is fixed, 2100W, not controlled by any institution, and the circulation of ordinary currency is determined by the state
however, almost all countries do not recognize bitcoin as legal, and the price fluctuation is very large, constantly being hyped. I think that using bitcoin as an investment means is the same as gambling.

7. 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, which is a kind of virtual currency.

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

features of bitcoin:

1. Circulation around the world: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

2. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

3. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
