Decentralization in virtual currency

1. bitcoin is valuable under certain circumstances, but it is worthless under certain circumstances. Because it's not legal tender. It is impossible for any country to get the right to issue legal tender to use any mining machine. Bitcoin is just a virtual number. While it's still possible to change money, change it quickly! It's too late to wait until it's worthless at the end.

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

8.

In bitcoin white paper "bitcoin: a peer-to-peer e-cash system", Nakamoto explained in detail how he designed the system. Among them, he established the main design principles of all blockchain systems since then

a real peer-to-peer e-cash should allow direct online payment from the originator to the other party without the need to go through a third-party financial institution

although the existing digital signature technology provides some solutions, if a trusted third party organization is needed to prevent "double payment", the main benefits (Brought by e-cash) will be lost

aiming at the problem of "double payment" in e-cash, we provide a solution with peer-to-peer network technology

in this network, transaction records are time stamped, hashed and merged into a growing chain, which is composed of hash based proof of work. If the proof of work is not redone, the resulting records cannot be changed

the longest chain is not only a proof of the observed sequence of events, but also a proof that it is generated by the largest pool of CPU processing power. As long as the computer nodes that control most CPU processing power do not join forces to attack the network itself, they will generate the longest chain and leave the attacker behind

the network itself only needs the simplest structure. Try your best to broadcast the information on the whole network. A node can leave and rejoin the network at any time. It only needs (when rejoining) to take the longest workload proof chain as the proof of the transaction occurred ring the node's offline period
