What are the three attributes of digital currency
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{rrrrrrr}
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
virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency
in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.
definition of digital currency:
the alternative currency in the form of electronic currency belongs to digiccy
digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as the digital expression of value, which is not issued by the central bank or authorities, nor linked with legal currency, but because it is accepted by the public, it can be used as a means of payment, and can also be transferred, stored or traded electronically
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm
the core characteristics of digital currency are mainly reflected in three aspects: first, e to some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; ② 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; ③ Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
the emergence of bitcoin poses a great challenge to the existing monetary system. Although it belongs to the generalized virtual currency, it is essentially different from the virtual currency issued by network enterprises, so it is called digital currency. This paper compares digital currency with electronic currency and virtual currency from the aspects of issuing subject, scope of application, issuing quantity, storage form, circulation mode, credit guarantee, transaction cost and transaction security.
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. 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)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin
based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior
6. Novacoin
another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities
the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward
7, infinitech
published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.
the functions and properties of digital currency are exactly the same as paper money, but its form is digital Mu Changchun, director of the digital currency Research Institute of the central bank, said that the central bank's digital currency is a digital alternative to paper money, that is, digital currency and electronic payment tools. If we regard the digital currency issued by the central bank as digital RMB cash, we can understand the concept of digital currency very well
Mu Changchun once described such a use scenario: as long as you and I have DC / EP digital wallets on mobile phones, we don't even need the network. As long as the mobile phone has electricity and two mobile phones touch each other, we can transfer the digital currency in one person's digital wallet to another person. Digital money does not need to bind any bank account when it is paid, unlike WeChat and Alipay bank. p>
fan Yifei, vice governor of the central bank, said that the central bank's digital currency focuses on replacing M0 (i.e. banknotes and coins), and maintains the properties and main features of cash, which meets the needs of portability and anonymity, and will be the best tool to replace cash
