Digital currency relies on

1.

digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)

digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes

based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

extended information:

the process of digital currency trading through the platform is as follows:

(1) investors should register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time

(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures

(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed

2. As early as 2014, the people's Bank of China has set up a special research group to study the central bank's digital currency. Until today, the central bank's digital currency has a real sense of landing. China may become the first economy to issue sovereign digital currency, and 2020 is expected to be the first year of global central bank digital currency

the DCEP issued by the central bank is a digital currency, which is very similar to Alipay and WeChat payment. But it is different from Alipay and WeChat, because it is more like paper money, and the third party can not get the information from both sides of the transaction. It is anonymous and centralization, and the endorsement of the state can be assured.

what is the use of central bank digital currency

from the perspective of the central bank, if the central bank wants to put in funds, it doesn't need these scientific and technological means to trigger conditions, and it could have done it

for users, they have one more option when paying. Users only need to download the central bank's digital currency wallet app, and then associate with their existing bank accounts to exchange the previous banknotes into the corresponding digital currency

for the current mobile payment, users are still accustomed to using Alipay and WeChat to pay. But how to say? Personally, Alipay was originally a professional payment software, but after all these years of development, the Alipay interface is extremely complex, and the user experience is not very friendly.
as for wechat payment, wechat started from social networking at first, and has evolved from professional social software to comprehensive software in recent years. To put it plainly, whether it is Alipay or WeChat, it seems that it has deviated from its original intention. This may bring opportunities to the central bank's digital currency

when will central bank digital currency become popular

according to the bank, considering that the early digital RMB is only limited to the pilot, it will not be issued in large quantities and promoted comprehensively in the short term, and the speed of currency circulation will also maintain a normal level

many people say that digital money has no effect on Alipay. I beg to differ. As Ma Yun said, sometimes it's just a document that beats you. What is the impact of the central bank's digital currency on Alipay? Let's wait and see.

3. The emergence of digital currency was born under the expectation of pursuing a more perfect social and economic transaction mode and Global trade facilitation. It was discovered in the process of using science and technology to graally explore this need. The history of digital currency should start with the creation of bitcoin
the creation of digital currency
the origin of digital currency can be traced back to the 1990s, and electronic gold is one of the best forms. E-gold came out in 1999. It is based on real precious metals. Another consistent digital currency service is LR. Founded in 2006, it is an online payment company in Central America. It allows users to convert U.S. dollars or euros into LR, and only 1% of the transaction cost can be exchanged freely. This kind of two-way service is used by some people to launder money, so it is inevitably shut down by the U.S. government under the charge of money laundering
then, a person named Nakamoto published an article called "bitcoin: a peer-to-peer e-cash system" in the cryptography forum, which gave birth to bitcoin. Compared with legal currency, bitcoin does not have a centralized discoverer, but is generated by the calculation of network nodes, and is composed of a series of complex codes generated by computers. Anyone can dig, buy and sell bitcoin, and it is an anonymous transaction and cannot be tampered with. As a result, it is surrounded by geeks of popular technology, pursuers of complete liberalism and speculators
digital currency can be divided into open mining cryptocurrency and issuing cryptocurrency. Digital currency is defined as an Internet-based currency or exchange medium, which is different from physical currency. Digital currency can realize instantaneous transaction and ownership transfer without borders

4. I'm too young to remember the birth of the Internet. When the Internet was booming, I was in high school, a little confused about what happened. At a family party, when my cousin bragged about how much money he made from buying and selling domain names, I thought it was stupid
it's not a reality. Up to now, I still think it's stupid to make money by buying and selling domain names. I know it happens sometimes. It's like a high-risk, low return investment
as a result, the Internet did. Now, 20 years on, domain names are cheap, and search engines make them brand specific Note: the author means that the convenience of search engines makes domain names cheaper and cheaper. Domain names are only related to brands.)
What does this have to do with the value of bitcoin
this is an example of how people's views on value change with the development of technology
at this point, most people see bitcoin as money. The chairman of the US SEC said, "yes, that's how drug gangs use it. Everyone I know thinks so.". It's called "bit coin" for a reason
bitcoin maximalists call it hard currency, critics call it fake money, and veteran players call it cyber currency
W bq89998 push the latest currency from time to time to ensure the minimum 10 times

A few days ago, some media reported that in the future, once legal digital currency really runs, application scenarios will penetrate into all aspects of social life

However, there is still a long way to go for legal digital currency to enter our life like cash. The first thing to solve is the technical obstacles. Although today's blockchain is regarded as the Internet of the 1990s, and its future is limitless, it is not mature enough to support the huge payment system

6. This question actually leads to a topic worthy of discussion: how do we see the "use" of the existing digital currency? Or how do we divide our understanding of digital currency

this division of cognition not only helps us understand digital currency, but also guides our behavior in the process of investment. So I'm going to analyze this topic in two or three articles
from the perspective of cognition, I divide all digital currencies into the following three categories:

the first category is that their value and consensus have been strongly recognized, almost indisputable, and have been transmitted from within the circle to outside the circle. This kind of currency is the least in the whole field of digital currency
this kind of currency typically includes bitcoin and Taiwan dollar. Bitcoin is recognized as "digital gold" and has repeatedly shown the characteristics of "sea calming needle" when the external political and economic environment is unstable; The profit model of platform currency is clear, especially the top three platform currencies have solid cash flow and income relying on the exchange
when talking about this kind of currency, both their consensus and value are highly recognized in the instry, and ordinary people can understand it outside the instry
when we talk about bitcoin with ordinary people, as long as we tell them that gold goes up, bitcoin goes up; When talking about platform currency with ordinary people, just tell them that platform currency is equivalent to the stock of securities companies, and they will immediately understand what we are talking about
although some people outside the instry do not agree with some consensus (for example, some people still do not agree with the value of bitcoin), this does not prevent ordinary people from understanding what we are talking about
the second type is that consensus has been reached, but the actual use value is still being proved, or the so-called "use value" can not show us the actual effect for the time being. This kind of currency is slightly more than the first kind, but also very few in the whole field of digital currency
this kind of currency typically includes Ethereum, EOS and cross chain projects in the field of smart contract

take Ethereum and EOS for example, they are highly expected by the instry. We hope to see that their smart contract function can proce killer applications and bring higher efficiency and lower cost to our daily life
in the past two years, Ethereum has developed a highly concerned defi Ecology (defi, decentralized finance, often referred to as distributed finance or decentralized Finance) in the instry
however, does this ecology have a direct relationship with the life of ordinary people or bring direct benefits? In fact, it does not exist at all. It is still a "niche ecology" in a small circle, far away from our daily life
the ecosystem developed by EOS in the past two years is far from the areas where we expect to bring value into play, and even there are not many people in the instry who pay attention to it
the concept of cross chain project is very novel when it first came out, and it is also considered by the instry to have great potential demand. But after a period of discussion, some people began to question whether this demand really exists
the instry has a consensus, or even a high consensus, on these currencies, but their current value is not satisfactory. Therefore, even if they are recognized by the instry, it is difficult for this consensus to be transmitted outside the instry, not to mention that ordinary people can understand these consensus and values
so we can't talk with ordinary people about what "defi" and "cross chain" are and what's the use

the third category is the currency whose consensus is still in the process of forming. The design objectives and scenarios of this kind of currency may not be understood or recognized by the instry, or even there are great differences in understanding. Their value is even more difficult to judge. This kind of currency accounts for the vast majority of the current market.
