1. blockchain is characterized by decentralization, trust, collective maintenance and reliable database
for example, Sunzi asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head to do notarization and add the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization. In the past, the village head was highly respected and had a good command of the accounts of the whole village. Everyone kept their money with him. This was the past trust in centralization. Now, everyone is worried that the village head will secretly misappropriate everyone's money. What should we do? So everyone sent an account book to everyone. Anyone who transfers money between them releases information through the loudspeaker. After receiving the information, everyone records the transaction in their own account book. This is called decentralization. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma and other families have ledgers
digital currency is abbreviation of digital currency. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Blockchain technology service upgrade technology

2. Digital currency is an application of blockchain
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

3. Decentralized, open and transparent payment and collection technology. If you don't understand, I'll take you to make one. Completely free blockchain digital currency.

As of May 2020, blockchain and digital currency are illegal in China
according to the announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risks of token issuance and financing, Article 2 no organization or indivial shall illegally engage in token issuance and financing activities. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects
Article 3 strengthen 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 currency and token and "virtual currency", and shall not buy or sell token or "virtual currency" as a central counter party, and shall not provide pricing for token or "virtual currency" Information intermediary and other services
extension data
"illegal financial institutions and illegal financial business activities ban" stipulates that:
eleventh, the criminal suspect, funds and property involved in illegal financial institutions and illegal financial activities, and the public security organs shall take compulsory measures according to law to prevent suspect from escaping and transferring funds and property. p>
Article 12 the people's Bank of China shall, after investigation and confirmation, make a decision to ban the illegal financial institutions and financial business activities, declare them illegal, order them to stop all business activities, and make an announcement
Article 13 if the people's Bank of China discovers that a financial institution opens an account, handles settlement and provides loans for an illegal financial institution or illegal financial business activities, it shall order the financial institution to stop the relevant business activities immediately. No unit or indivial may use the relevant funds without authorization5. We know that the state has always advocated "no money" blockchain. That is to say, don't use the chain&# 8204;&# 8204;&# 8204; Currency, support technology development, do not support issuing currency
of course, the coin here is what we often call token, which originally means token (temporary) in computer identity authentication. With the popularity of blockchain and digital currency, people have a variety of translations for token, including token, integral, certificate, logo, indicator, etc
the understanding of token in the market can be divided into two categories
in the first category, 99% of the people think token means token, because 99.9% of the projects do the same thing. Set up a foundation, build a website, write a white paper, and then go to ICO. Because most of the projects are still in the conceptual stage, token itself has no other meaning except trading, so people call it token, which performs the function of currency to some extent
in the second category, professionals and institutions are more willing to translate token into proof of equity, or token. For example, a person's identity certificate, academic certificate, equity, bonds, points, bills, etc., are authentic and tamperable because of the proof of rights and interests. Every proof of interest becomes more secure and reliable through the protection of cryptography
therefore, blockchain is not only a technology, but also a new mode of proction and organization, even a new thinking
so, the question now is, does the blockchain project have to issue currency
answer: you may not issue currency. Not all blockchain projects need to be issued with currency, and it is not necessarily blockchain projects that issue currency
for example, the alliance chain does not need to issue coins. For example, Tencent's q-coin, in principle, is also a kind of currency, but it is not a blockchain project
therefore, the two are not related, but if they are public chains, they need to issue coins. Why
let's take bitcoin as an example. Bitcoin system as a public chain must rely on the existence of bitcoin. Public chain obtains the stability and non tamperability of its system through the nodes distributed all over the world, and these properties are the basis for the existence of public chain
imagine that if the bitcoin system is unstable or can be easily tampered with, bitcoin will be worthless. These nodes are not set up by one or several companies, otherwise they are equivalent to private chain or alliance chain. These nodes must be built dynamically by many participants. And the existence of these nodes must need some kind of incentive, otherwise why do the builders of these nodes want to participate in your system. And this kind of incentive must be integrated with the blockchain system, and it must be money
then why is it currency, not legal currency, such as RMB, as an incentive
if RMB is used as incentive, because RMB should be stored in the RMB account, and the account itself is centralized, so it's easy to be controlled. Just think about why domestic bitcoin exchanges are so afraid of the central bank, and they are afraid of being weaned. In addition, RMB can't react with smart contracts within the blockchain
the electronic currency issued by the central bank can not be used as the original currency and incentive of a blockchain system. Why
if the central bank or a rich person wants to destroy a project, they just need to take out enough e-money to do enough nodes and attack 51%. Therefore, it is impossible to use the e-money issued by the central bank as the original currency and incentive blockchain system. However, blockchain projects with independent native currency and incentives have no such worries
If a person or organization wants to get enough nodes to carry out 51% attacks, it must first get more than 50% enough coins, and the amount of coins in the market is certain, so before it gets enough coins, the soaring price will make it hard for him to bear
therefore, a public chain project must have money. A public chain project without money is like a castrated person
in addition, only through the token and reasonable stimulation of output, can the proction relationship be changed and the value of blockchain be brought into play. Therefore, the project must have token, which can promote the development of the project faster. Token solves the problem of incentive and consensus, and incentive solves the problem of autonomy. The positive autonomous economic ecosystem and the underlying technology of blockchain are a perfect combination.

6. Blockchain digital currency refers to cryptocurrency. The underlying technology is blockchain. There are many cryptocurrencies. Bitcoin is more famous. Detailed digital currency can be found in cryptofinance mimacaijing.
7. Blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain
the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
according to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain.
