Digital currency to build the latest system

1.

1、 Different definitions:

1. virtual currency:

virtual currency refers to non real currency

digital currency:

digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

3. Cryptocurrency:

cryptocurrency is a kind of transaction medium that uses cryptography principles to ensure transaction security and control the creation of transaction units

4. Token (token):

a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English

Second, the characteristics are different:

1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency

2. Digital currency:

is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities

Cryptocurrency:

cryptocurrency is based on the decentralized consensus mechanism, which is opposite to the banking and financial system relying on the centralized regulatory system

4. Token (token):

usually needs to be exchanged for money, used in shops, playgrounds, mass transportation and other places, as a voucher to use services and exchange goods

extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

1. Enjin (enj)

in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers

Cardano (ADA)

compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:

scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol

interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol

Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform

With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projects

Nash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here

4. Basic attention token (BAT)

bat mainly solves the problem of advertising:

user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users

the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake

in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast

5, chainlink (link)

chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract

companies including Google are supporting the development of chainlink. Here is a list of chainlink partners

one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present

Ethereum (ETH)

Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run

3. It is very clear in the speech of the central bank that the digital currency is M0. What is M0? M0 is cash. We speculate that the basic framework for the central bank to issue digital currency in the future should be a two-tier structure. The core is the database of the central bank, and the periphery is the blockchain of different instries, regions and third parties. Why? Only by using a decentralized system in the second layer can you ensure that the money is controlled by the users themselves and that the digital currency really becomes M0

we speculate that once the central bank issues digital currency in the future, the periphery of the structure must be a decentralized system. At present, blockchain is the best choice

when talking about digital currency, the central bank also mentioned another concept, which is called programmable currency. How to understand? For the computer, it has a certain internal self-control function. Take the early object-oriented language as an example, it requires at least two functions, one is the constructor, the other is the destructor. You have to solve the problem of its creation as well as its extinction

through programming, the central bank can control the whole life cycle of money creation, circulation and withdrawal

in the absence of digital currency and programmable currency, the currency issued by the central bank circulates freely in the society. How to return to the cage in the end? One is the return of derivative currency of commercial banks, the other is the return of basic currency of central bank. The former is controlled by the central bank through deposit reserve and other policies, while the latter is controlled by the tax system. If we go up to programmable digital currency in the future, the central bank will have much more control. Even in circulation, control can be increased. That's why central banks are very interested in blockchain technology.

According to the published data and conclusions, China will be ahead of foreign countries in terms of science and technology theory, e-payment habit and mature payment system{ RRRRR}

finally, in China, the electronic payment system is relatively perfect, that is to say, if digital currency is implemented in the future, it can be easily implemented, and the related construction cost is relatively low. Moreover, whether it is digital currency or electronic payment, the difference between the two is not big, and digital currency can adapt to more diverse scenarios, and people can accept it more easily, It will not become unaccustomed because of the sudden change, which will also lay a good foundation for the development of digital currency in our country. However, such a system and payment habit are not possessed by other countries at all, and most countries are not used to electronic payment, so there is no digital currency base at all

Do you mean there is no essential difference between digital currency and the existing monetary system? I don't know where to draw this conclusion. At present, the general digital currency mainly includes bitcoin, Ethereum, reborn, Leyte and other virtual currencies. These virtual currencies are very different from the existing monetary system! For example:

1. issuers: the issuers of existing legal tender are national government agencies, generally the central bank. Bitcoin and other digital currencies are issued according to the program encryption algorithm. If we want to say that the issuing subject, even one person can issue them. There is no credibility or coercion

2. credibility. The existing monetary system, that is, legal tender, has the endorsement of national credit, which has more credibility. Bitcoin and other digital currencies rely on algorithms, which are often issued by a community or even indivials, with weak credibility

3. mandatory. The existing monetary system, namely legal tender, is issued by the state and circulates in a country or region according to law. Digital currencies, such as bitcoin, do not have the power to enforce the law

4. volatility. In the current monetary system, there are exchange rate fluctuations in various legal currencies, but they are basically in a relatively stable state. As for bitcoin and other digital currencies, you can look at the market of digital currencies on investing. It can be seen that the price difference of bitcoin even one day is more than 10%, which is obviously unstable

   

6. In fact, the technical systems corresponding to various digital currencies are quite different
moreover, the development of digital currency is still immature.

7. Non small query, more is, but the daily trading volume is less than 10 billion do not consider

8. It doesn't belong to
the objects of special ecation include blind children's ecation, deaf children's ecation, mentally retarded children's ecation, gifted children's ecation, speech disorder children's ecation, emotional and behavioral disorder children's ecation, multiple disabled children's ecation, etc., excluding attention deficit children.

9. In addition to the postal service and Weizhong, the Bank of Changsha is now cooperating with a public platform called SMIC blockchain, which seems to be a blockchain loan business.
