What do you mean by the letter C in digital currency

1.

The digital currency of the central bank is DCEP

the name of the digital currency developed by the central bank is DCEP (digital currency electronic payment). DC is digital currency. EP is electronic payment. Payment transmits digital things through a certain way, not paper currency. Therefore, electronic payment itself has the attribute of digital currency

The characteristics of digital currency are: low transaction cost; Fast trading speed; Highly anonymous

Application of digital currency

I. fast, economic and safe payment and settlement

cross border payment helps RMB internationalization. In 2015, the settlement volume of cross-border payment involving current account is about 8 trillion yuan. To accelerate the internationalization of RMB, cross-border payment and settlement procts and solutions with low cost, high efficiency and low risk are needed

At present, there are still a lot of repetitive human work in the bank's electronic loan process and processing process, and as the basic support of loan issuance, many of the collateral has the situation of false pricing or multiple or even no collateral. We can consider using digital currency to price and track bank collateral:

3. Bill finance and supply chain finance

in recent years, various bill market businesses based on commercial bills have grown rapidly, and bill financing procts have become a hot area of Internet financing. However, about 70% of the current bill businesses in China are still paper transactions, Supply chain finance is also highly dependent on labor costs

2. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

3. Here's a brief introction to several mainstream digital currencies to give you a rough idea. After that, I will talk about the specific currency from time to time

bitcoin is the originator of digital currency and the most valuable virtual currency. Because blackmail virus only takes bitcoin, it has entered the public view. The soaring price of bitcoin in 2017 has attracted a large number of investors to enter the digital money market. Because the number is small, it is only 21 million, which has a strong deflationary attribute
of course, I am extremely optimistic about the future of bitcoin. Of course, many people are not optimistic about digital currency. Here, it is most pertinent to quote Krugman's view:
"at least for now, buying bitcoin is still a good investment. But that doesn't mean the experiment was successful. The original intention of establishing a monetary system is not to make those who hold money rich, but to make transactions convenient and benefit the whole economy. And none of these bitcoins came to us. "
reborn currency
a protocol currency issued by reborn, which is the base currency of reborn network. It can circulate in the whole reborn network, with a total amount of 100 billion, and graally decreases with the increase of transactions. Reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system, Ripple labs (formerly known as opencoin) is the operating company of ripple coin
unlike bitcoin, reborn is a kind of transaction protocol, which is called smart contract in technical terms. It supports people to pay in any currency, and does not need a central data exchange center, so the transaction confirmation time of ripple is only 35 seconds, while that of bitcoin is 10-40 minutes

Ethereum
Ethereum is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer
there is a key difference between the blockchain technologies used by Ethereum and bitcoin. Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
unlike bitcoin, the value of Ethereum depends on whether the applications on the platform of Ethereum are prosperous or not, just like the price of oil will rise with more machines using oil

bitcoin cash
bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block
strictly speaking, however, there are different opinions on whether this is a new branch of bitcoin or another kind of "counterfeit currency". But now the offer of bitcoin cash is nearly 20000 yuan, so it's not too much to use it as a kind of "Shanzhai coin" to divide bitcoin traffic

IDA coin, ADA in English, is a proct of Cardano project. The total amount of Aida is 4.5 billion yuan, and 3 billion yuan will participate in the subscription. Among them, 2.5 billion ADA will be used for platform subscription, 500 million for the financial support of the development company's operating company, and 1.5 billion ADA coins will continue to be issued in the form of block awards
Cardano is a project started in 2015 to change the way cryptocurrency is designed and developed. This project is aimed at technical reformers, technical improvements to bitcoin and existing platforms. If bitcoin, Ethereum and other projects have many other shortcomings, Cardano can solve them<

lightcoin
a currency based on bitcoin protocol, but it does not require very high computing power, and it can also be mined by ordinary computer. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
for a long time, there has been a voice that "lightcoin will replace bitcoin", which is impossible. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin<

stellar currency
stellar currency, a digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and legal tender. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
star is a diversified team. The board members include Keith rabois, former COO of square, Patrick collison, CEO of stripe, Jackson Palmer, co-founder of dogcoin, and naval Ravikant, co-founder of angellist, who will be the consultant of the project< New economy movement, or NEM, was founded on January 19, 2014. The founder is a mysterious person in bitcointalk.org forum called utopianfuture. The original intention of utopian future was to build a second-generation digital currency NXT. He then realized that NXT's distribution model was unreasonable, so he devoted himself to NEM with egalitarian distribution
as a kind of cryptocurrency, new coin does not need much computing resources to maintain the operation of nodes. The proof of importance (POI) engine of NEM reces the threshold of computing resources to participate in non-traditional blockchain<

dascoin
formerly known as black coin, is a kind of counterfeit currency of bitcoin, which focuses on anonymous function. There are many innovations, such as master node network, fast payment, mixed currency anonymous technology, proposals can vote, and developers have fixed budget support. The core consists of a unique incentive P2P network. Miners are rewarded for maintaining blockchain security; The main node holders are rewarded for verifying transactions, storing data and providing a variety of services
the feature of anonymity meets the needs of some investors for absolute privacy. Although bitcoin is also widely used in money laundering and other illegal transactions e to its anonymity, it is only "pseudo anonymity", and the transaction of bitcoin can still be traced back to the traders themselves.

4. Is a number one thing? These two digital currencies are not the same thing, because they are two different platforms.

5.

f=N μ N is the positive pressure, that is, the pressure acting on the contact surface, μ It is the dynamic friction coefficient, which refers to the influence factors of the roughness of the contact surface on the friction. Or use the balance f = f; It's only used when it's stationary or moving in a straight line at a constant speed, but it's the most used in junior high school

the so-called friction is the force that hinders the relative motion of the object, and the direction of friction is opposite to the motion direction or relative motion direction of the object. The conditions of friction are as follows:

(1) two objects must contact each other

(2) there was extrusion between two objects

(3) there is a tendency of motion or relative motion between two objects

If an object is stationary on a horizontal plane, it will not be affected by friction if it is not pushed or pulled. If thrust or pull is received, it belongs to the category of static friction. The size of friction is equal to that of pull or thrust, and has nothing to do with the gravity or pressure of the object. Only the maximum static friction is related to the pressure or gravity on the object

if the object is not pushed by 10N force, the object will be subjected to static friction, which is equal to the thrust. Just push with 15N force, and the friction force on the object is the maximum static friction force. If the thrust force is increased later, the friction force will not change. Theoretically, the sliding friction of objects is less than the maximum static friction, but it is generally considered that they are equal

The friction force is f = 15-10 = 5N

extended data:

methods to increase beneficial friction

(1) increase the roughness of contact surface

(2) increase the pressure

(3) change rolling friction into sliding friction

(1) replace sliding friction with rolling friction

(2) make the contact surface separate [form a layer of air cushion or magnetic suspension on the contact surface of the object]

(3) decrease the pressure

(4) rece the roughness of the contact surface

In engineering technology, people often rece friction by applying lubricating oil. The science of this problem is called tribology, which is a branch of mechanical manufacturing

If two objects, which are in contact with each other and squeeze each other, but relatively still, only have a relative sliding trend under the action of external force, but do not have relative sliding, then the force between their contact surfaces hindering relative sliding is called "static friction". When the static friction increases to the maximum, the object will move

size: the static friction varies according to the external force, but there is a maximum value, which is called the maximum static friction. The maximum static friction is slightly greater than the sliding friction

direction: tangent to the contact surface, opposite to the direction of relative motion trend

On the basis of a large number of experiments, G. amunton and C. - A. de Coulomb proposed the following law of friction in 1699 and 1781:

① the friction between two objects in contact does not exceed a certain maximum value, which has nothing to do with the size of the contact area

(2) the maximum value of friction is proportional to the normal pressure n between two objects

(3) the direction of friction is opposite to the sliding direction of the object, and its magnitude is directly proportional to the normal pressure n between the two objects

the above conclusion is only a rough empirical rule, but because it was found in the early days of mechanical science, it was called the law of friction, also known as Coulomb's law

7. It's not true, it's fake. It's issued by swindlers. Money is issued by the state and can be circulated and used normally. What's the use of virtual money!
