Is electronic city related to digital currency
several characteristics of digital virtual currency
1, decentralization
2, independent e-wallet
3, open source code
4, measurement and issuance
5, negotiable
investment in virtual currency is now very promising
1、 Different definitions:
1. Electronic currency:
refers to the currency paid by electronic means
2. Digital currency:
is a virtual currency based on node network and digital encryption algorithm
Electronic currency: Based on computer technology, it can be widely used in the fields of proction, exchange, distribution and consumption. It has many functions such as financial savings, credit and non cash settlement2. Digital currency:
e to some open algorithms, digital currency has no issuers, so no one or institution can control its issuance; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
Third, the same point:the circulation mode of e-money and digital money is two-way circulation
extended data
e-money is the virtualization of the value scale of real money and the function of payment means. It is a kind of money without monetary entity. Electronic currency is an invisible currency based on highly developed electronic technology
the value of e-money is transferred from the consumer to the seller through the sales terminal, and then the seller redeems the money. The e-money held by the merchant is sent to the e-money issuer to redeem the money, or to the bank. The bank debits the corresponding amount on its account, and then the bank settles with the issuer through the clearing institution
electronic money can transfer money value directly among the holders. It does not require the intervention of third parties, such as banks. This is also the essential difference between electronic money and traditional cash card and transfer card. p>
1. Application of different
digital currency: fast, economic and safe payment and settlement; Bill finance and supply chain finance; The real right of collateral is digitalized
e-money: the seller sends the buyer's payment instructions to the seller's acquiring bank through the payment gateway; The acquiring bank obtains the authorization from the issuing bank through the bank card network, and sends the authorization information back to the seller through the payment gateway; After obtaining the authorization, the Seller shall send the buyer the shopping completion information. If payment acquisition and payment authorization cannot be completed at the same time, the seller should send payment acquisition request to the acquiring bank through the payment gateway, and transfer the transaction funds from the buyer to the seller's account. The final inter-bank settlement is completed by the payment system between banks
2. Different characteristics
digital currency is characterized by low transaction cost, fast transaction speed and high anonymity
e-currency is characterized by anonymity, saving transaction cost, saving transmission cost, small holding risk, flexible and convenient payment, anti-counterfeiting and anti repetition, and non traceability
Digital currency can be divided into three categories: completely closed, unrelated to the real economy and only used in specific virtual communities, such as world of warcraft gold; It can be purchased in real currency but not converted back to real currency, and can be used to purchase virtual goods and services, such as Facebook credit; It can exchange and redeem with real currency according to a certain ratio. It can purchase both virtual goods and services and real goods and services, such as bitcoine-money: e-cash based on the Internet environment and keeping the binary data representing the value of money in the hard disk of the computer terminal; An electronic wallet that keeps the value of money in an IC card and can be circulated out of the bank payment system
It doesn't matter
the central bank's digital currency is digital RMB, which is issued by the people's Bank of China. On March 9, 2018, Zhou Xiaochuan, then governor of the central bank, officially disclosed the name of the legal digital currency being developed as DCEP at a press conference
DCEP is the abbreviation of digital currency electronic payment. This means that the central bank's digital currency will have the al functions of legal currency and electronic payment at the same time In September 2013, the Ministry of Public Security announced 10 typical pyramid selling cases, among which "Cloud Data Trade" is a large-scale pyramid selling mode in China
extended data:
specifically, the characteristics of DCEP are mainly reflected in finance and technology
1. As far as its financial characteristics are concerned, the functions and attributes of the central bank's digital currency are exactly the same as those of the RMB paper currency, which is only a digital version of the paper currency. This shows that digital currency is legal tender, and it depends on national credit to maintain the circulation system of digital currency. Mu Changchun, director of the digital currency Research Institute of the central bank, clearly pointed out that DCEP "is a digital payment tool with value characteristics"
In economics, M0 is often used to refer to the cash circulating outside the banking system. The central bank's positioning of DCEP is to replace M0, that is, to replace cash2. In terms of technical features, the digital currency of the central bank has not fully adopted the blockchain technology. The blockchain research group of the digital currency Research Institute of the people's Bank of China has pointed out in a paper that the processing efficiency of the blockchain system needs to be improved. The encrypted assets based on this technology can not guarantee the stability of its anchored assets. At the same time, its decentralization also conflicts with the central bank's centralized management requirements
however, it is said that digital currency draws lessons from some of these technical concepts, such as asymmetric encryption, smart contract and so on. The new cryptocurrency system has the advantages of security, controllable anonymity and unforgeability, which makes up for the problems of high cost, difficult tracking and large counterfeiting
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.

blockchain is a distributed account book technology, and digital currency is currently the main application mode of blockchain technology
-
digital currency, based on the characteristics of blockchain, such as decentralization, traceability, non deletion and modification of records, confidentiality, convenient and rapid transaction, can be used as the carrier of asset digitization to a certain extent. Digital currency provides a feasible tool for asset digitization, safe, convenient and transparent transaction
-
digital currency is illegal in China. In 2017, many ministries and commissions of the state have issued relevant issues, please search online
Relevant national leaders pointed out that blockchain technology is an important breakthrough for independent innovation of core technology. Therefore, more and more attention will be paid to the application of blockchain technology, and the central bank is also studying DCEP, but it is not clear when digital currency will enter the legal application -
a few countries, such as the United States, Japan and Singapore, are tolerant of digital currency:
1) the United States: there are usdt, ETH, and Libra in the future
2) Japan: in April 2017, Japan implemented the revised capital settlement law, stipulating that digital currency and Japanese yen are legal tender and can be traded with each other
3) Singapore: Singapore is tolerant of digital currency, and it has become a common practice for Singaporeans to invest in digital currency< br />
1. Digital currency
digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and password currency belong to digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
features: the use of P2P peer-to-peer network technology to issue, manage and circulate currency theoretically avoids bureaucratic examination and approval, so that everyone has the right to issue currency
Electronic money means that a certain amount of cash or deposit is exchanged from the issuer and the data representing the same amount is obtained. By using some electronic methods, the data is directly transferred to the payment object, so that the debt can be paid off. Strictly speaking, consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form. In short, when we deposit money into our bank account, there will be an extra number in the bank account, which means how much money we have saved. In this process, we give the banknotes in our hands to the bank, and the bank adds a number to our bank card, which is our electronic currencyfeatures:
< UL >e-money and paper money (or physical money) can be easily converted to each other
the data of electronic currency corresponds to the same amount of physical currency
we need to pay physical money to the issuers of e-money (banks and other financial institutions) in order to exchange for the same amount of e-money
3. The similarity between digital currency and electronic currency: both exist in the form of electronic data
The differences between digital currency and electronic currency are as follows:electronic currency has an issuing institution, and the corresponding amount of physical currency in the institution can be exchanged with physical currency; However, digital currency has no specific issuing institution (decentralization) and can only exist in network data
at present, there is no international consensus on whether digital currency is a currency or not, so in China, the main form of digital currency is "investment proct", which is a rather risky investment proct, and only a few businesses are willing to accept digital currency consumption; Of course, some countries (Germany, etc.) have officially recognized the currency status of digital currency
In recent years, the rise of financial technology drives the digital and intelligent development of finance, and the form of money is also evolving. Recently, the news of digital currency has attracted people's attention, and there is still a lot of gap with the current online payment
1. The factor of investment supply and demand is actually not independent, and investors' demand for digital currency is also affected by various news factors. However, from the price surge of last year, in the absence of obvious policy and other news, The admission of investors and investment institutions will also promote the price growth
2. Policy factors are also important factors affecting the price of digital red packets. In the past, the implementation and formulation of policies in South Korea, Japan, the United States and China have affected the price trend of bitcoin
3. The real financial factors and the instability of the real financial world make the demand for digital assets rise from time to time. For example, the Chinese government's policy adjustment, the brexit of the UK, the setback of the global stock market at the beginning of 2018 and other events all give play to the hedging characteristics of digital currency
4. Technical factors. Although the security of digital currency has been highly respected in its development, several technical crises still occurred in its development history. For example, bitfinex, the largest bitcoin dollar exchange, was attacked by hackers and stole 120000 bitcoin, and bitcoin fell by 25% in the following six trading days
5. Good news and bad news will affect the fluctuation of currency value
6. The market trend will be affected by the actions of the leading enterprises in this field, platforms, digital currencies with large market share, leaders with great influence in the market, etc
besides, choosing a good project can avoid risks to a certain extent. For example, HNB, the next generation of decentralized blockchain economy, is a reliable project. It relies on the real economy, and at the same time uses value exchange to continuously create endogenous value. It uses blockchain to build an economy, so that everyone can participate in it and get returns through labor, instead of relying on currency speculation.
