Virtual currency of payment concept
digital currency is also different from virtual currency. For example, the well-known Q coin and the money recharged in various games are virtual currency. These virtual currencies can only be purchased with real currency, but cannot be converted into real currency
in the world, bitcoin is probably the most famous digital currency. In addition, there are "Wright coin", "Dog Coin" and "Yuan Bao coin" in China.
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
Virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies
virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software
extended data:
real risk
as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers
fraud
the private transaction of online virtual currency has realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints. In addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players
Taking Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>
impact system
in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies
if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation
reference: network virtual currency
virtual currency and electronic currency are not the same concept
the definition of e-money is to convert a certain amount of cash or deposit from the issuer and obtain data representing the same amount. By using some electronic methods, the data can be directly transferred to the payment object, so as to pay off the debt. E-money means that consumers pay traditional money to issuers of e-money, and issuers store legal money of equal value with traditional money in electronic devices held by consumers
electronic currency is the electronization of the legal tender, including our common bank cards, Internet banking, electronic cash, etc., as well as the third party payment developed in recent years, such as Alipay, fortune paid and so on. No matter what form these electronic currencies are and through which institutions they circulate, their original source is the legal money issued by the central bank
but virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, Tencent Q currency and other game currency, such virtual currency is mainly limited to circulation in a specific virtual environment. After the emergence of bitcoin, through the blockchain technology to better solve the problem of decentralization, distrust, to achieve global circulation, is sought after in the world. Electronic currency and virtual currency are collectively referred to as digital currency
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

The differences between e-money and virtual money are as follows:
1. Electronic money refers to using a certain amount of cash or deposit to exchange from the issuer and obtain data representing the same amount, or through the quick payment service launched by the bank and the third party to transfer the balance in the bank through some electronic ways, so that transactions can be carried out. Strictly speaking, it is a kind of currency that consumers use the bank's Internet banking service to store value and make quick payment to the issuers of electronic currency, and make consumers trade electronically through media (two-dimensional code or hardware equipment)
Virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" The detailed explanation of electronic currency is as follows:1. Concept: it is an encrypted serial number representing cash, which can be used to represent the currency value of various amounts in reality. With the transformation from paper-based economy to digital economy, e-cash will become the mainstream
2. Features: anonymity, transaction cost saving, transmission cost saving, low holding risk, flexible and convenient payment, anti-counterfeiting and anti repetition, non traceability
There are two kinds of e-cash: one is based on the Internet and keeps the binary data representing the value of money in the hard disk of the computer terminal; One is the electronic wallet that keeps the monetary value in the IC card and can be circulated without the bank payment system4. Definition: 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
1. Network virtual currency can be roughly divided into two categories:
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and uses these virtual game data to buy Herbs and equipment, or in some special games as a scoring unit to increase the fun of the game, which is an embodiment of the player level. But it can only be used in your own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community and the realization of game networking, there has been a "financial market" for virtual currency, where players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third category refers to bitcoin, Ruitai coin, Laite coin, Weimeng coin and other digital cryptocurrencies
2. Electronic money refers to the exchange of a certain amount of cash or deposit from the issuer and the acquisition of data representing the same amount. By using some electronic methods, the data can be directly transferred to the payment object, so as to pay off the debt.
virtual currency is still very deep for us issued a statement about the virtual currency directly on the hot search of Alipay. But for this virtual currency, everyone has different views. However, it is more appropriate to ban virtual transactions from the public's point of view, because most people rarely touch virtual currency
in a word, for people who don't know much about virtual currency, the water is very deep. We must be more cautious when we invest. However, in view of Alipay's prohibition of virtual transactions, may also show its superiors' attitude towards virtual currencies. strong>
