What is the consensus of bitcoin decentralization

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. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.

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. Bitcoin is a kind of virtual digital currency proposed by Nakamoto in 2009. It is characterized by no centralized issuing institution and a fixed total of 21 million pieces. It is not a one-time issue and needs to be proced by miners. Due to the decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.

5.

Bitcoin is a kind of virtual encrypted digital currency in the form of P2P. Different from 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 the use of cryptography design to ensure the security of all aspects of money circulation. However, on September 4, 2017, the central bank and other seven ministries and commissions announced that virtual currency trading is prohibited in China, and bitcoin is prohibited from circulating in China

according to the first article of the notice on preventing the financing risks of token issuance, we should accurately understand the essential attributes of token issuance financing activities. Token issuance financing refers to the illegal sale and circulation of tokens by the financing subject to raise the so-called virtual currency such as bitcoin and ether coin from investors. In essence, it is an unauthorized illegal public financing behavior, which is suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities

Relevant departments will closely monitor relevant developments, strengthen cooperation with judicial departments and local governments, strictly enforce the law in accordance with the current working mechanism, and resolutely deal with market chaos. If suspected crimes are found, they will be transferred to judicial organs. The token or "virtual currency" used in token issuance financing is not issued by the monetary authority, does not have such monetary attributes as legal compensation and compulsion, does not have the same legal status as currency, and cannot and should not be used as currency in the market

extended information:

Article 3 of the announcement on preventing the financing risk of token issuance strengthens the management of token financing trading platform. From the date of this announcement, any so-called token financing trading platform shall not engage in the exchange business between legal tender and token and "virtual currency", nor buy or sell token or "virtual currency" as a central counterpart, nor provide pricing, information intermediary and other services for token or "virtual currency"

for the token financing trading platform with illegal problems, the financial management department will request the competent department of telecommunications to close its website platform and mobile app according to law, request the network information department to remove the mobile app from the app store, and request the instrial and commercial administration department to revoke its business license according to law

Article 4 financial institutions and non bank payment institutions shall not carry out business related to token issuance financing transactions. All financial institutions and non bank payment institutions shall not directly or indirectly provide procts or services such as account opening, registration, trading, clearing and settlement for token issuance and financing and "virtual currency", nor undertake insurance business related to token and "virtual currency" or include token and "virtual currency" into the scope of insurance liability. Financial institutions and non bank payment institutions shall report to the relevant departments in a timely manner if they find clues of violation of laws and regulations in token issuance financing transactions

6. The design of "decentralization" determines that the "centralized" government cannot touch bitcoin
the emergence, development, amendment, circulation and extinction of bitcoin do not depend on the government, so "whether the government allows" has nothing to do with "whether bitcoin exists"
for example, the birth, development and extinction of the solar system do not need the permission of the government
if bitcoin is exchanged with the government controlled "legal tender" (such as US dollar), the government can influence the performance of bitcoin by controlling the legal tender
if the recognition of such assets reaches the bottom line of% 35 in 2019, the world pattern will be more reasonable, transparent and open

how should we deal with the coming risks- Buy bitcoin quickly to deal with the risk of "no bitcoin".

7. In bitcoin and other blockchain currencies, there is also the problem of how to reach a consensus. In other words, the core issue of bitcoin or other blockchain currencies is how to reach a consensus in a decentralized environment

blockchain is not only the core technology behind bitcoin, but also the infrastructure supporting bitcoin. Therefore, when talking about the consensus of blockchain, we must talk about the consensus of bitcoin

the core breakthrough of bitcoin is to reach a consensus on transaction events in the case of decentralization, that is, to reach an agreement on the effectiveness of a transaction without a central organization<

bitcoin's method to achieve this consensus mainly includes two parts:

incentive; That is, each block generates a certain amount of new bitcoin to motivate participants
introce external resources to ensure safety; That is, to ensure the security of consensus through a large number of external calculations, that is, proof of power

this is also the method adopted by almost all POW currencies. For example, dent, Wright coin, sand coin, dog coin and so on.

8. The "bitcoin consensus conference" is held by coindesk, a media and research company in the field of blockchain. The guests will include experts in the field of blockchain and representatives of the development project of memory digital currency. The number of participants is graally increasing every year, and the tickets are also rising all the way. When I played stock before, the teacher of Yingfu College of Finance and Economics said that it was more professional

it is worth noting that the price of bitcoin fluctuates significantly ring the annual meeting, and it also becomes a hot spot in bitcoin market.

9. 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
mining is a 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
of course, you can also go to bitcoin house to learn about it.
