What should a decentralized currency do

1. According to Hou Jietai: the so-called centralization refers to subtracting the mean value of a variable from its expected value. For sample data, each observation value of a variable is subtracted from the sample average value of the variable, and the transformed variable is centralized
for your question, subtract the mean from each measurement.

2. Because bitcoin does not exist in the issuing institutions (bitcoin is extracted from the network), nor does it exist in banks, but directly through a personal to personal transfer.

3. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

4. That is, no one can control, not be controlled by the living center of a living group. Therefore, it can not be used as legal tender recognized by the state. There are a group of money speculators who argue that virtual currency will replace paper money every day. It's all bullshit. We must pay attention to investment risks. Now there are many pyramid schemes with virtual digital currency gimmicks to cheat money

5. In token economics, decentralized money is not the only object of value circulation and measurement. Therefore, a fixed amount of decentralized money does not necessarily lead to rejection by the market
decentralization in decentralized money contains multiple meanings: decentralization of money issuance, decentralization of money circulation, decentralization of money withdrawal...
as far as our current economic system is concerned, the issuance of money is carried out by the central bank or other similar institutions and endorsed by the national credit. Therefore, the issue of money is obviously a kind of centralized, controlled by the government or institutions. However, in the current economic system, the circulation of money is decentralized
although in our current financial system, the vast majority of money has been circulating through banks, this mode of circulation is mostly controlled by the money owners themselves, that is to say, the circulation of money is not controlled by central institutions. In addition to some specific financial requirements, some circulation has been regulated; Or the judicial organs may intervene and forcibly manage the circulation of money. In proportion, these centralized operations are very few. Therefore, we can say that in the existing economic system, the circulation of money is decentralized< In fact, the central bank and other financial management institutions make use of the power of currency issuance to regulate the whole market and maintain the stability of economic development and currency
we have learned in economics that the total amount of money circulation should match the current trade situation. In other words, the total amount of money circulation is closely related to the economic situation. The circulation of money needs to be regulated to influence the market; And the market also forces the regulatory agencies to regulate the currency through various feedback, so as to maintain the stability of the currency.

6. In a system with many nodes, each node has a high degree of autonomy. Nodes can connect freely to each other to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form nonlinear causality through the network. This open, flat and equal system phenomenon or structure is called decentralization
this is the reason for the decentralization of digital currencies such as bitcoin, Ruitai and Qianjin.

7. How to answer is the foreign exchange market ah, people clearly said is cryptocurrency. The introction of currency circle is to understand the birth of digital currency first, that is, to recognize the decentralized value of digital currency, so as to distinguish the currency on the market. The first is the mainstream currency based on technology and concept, such as bitcoin, Ethereum, etc., and the second is the Shanzhai currency. Of course, there are still some people who get attention with the help of new concepts such as resonance. How many people have been cheated by the token issuing scam in 17 years? You must have heard about it, so the mode depends on the originality and the problems it solves. If you are a programmer, you can refer to books like "master bitcoin". If you are not, you can also read the introctory book "ten years of blockchain", and then join various communities. There are many materials for Xiao to refer to. The second is trading. In China, stable currency trading and OTC are the main procts. In this regard, an exchange (e-coin) is doing activities, so we can actually experience the operation process of the currency market.

8. In addition to bitcoin, Ruitai, Laite and Ruibo, the mainstream digital currencies have certain liquidity, other Shanzhai currencies basically have no liquidity. The related application is even more deficient, just staying in the theoretical stage

of course, it is not ruled out that large institutions will develop liquid digital currencies in the future.

9. Theoretically, centralized blockchain technology is much safer. Only RMB, US dollar, Japanese yen and other traditional legal currencies are centralized.
