Research types of digital currency
Publish: 2021-05-12 07:05:14
1. Yao Qian, head of the preparatory group of the digital currency Research Institute of the central bank, said that the digital currency issued by the central bank is mainly to replace physical cash, rece the cost of issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transactions
Huang Zhen, director of the Institute of financial law of Central University of Finance and economics, said that digital currency mainly refers to the form of currency and will not cause currency shrinkage. The issuing scale of money is still controlled by the central bank, while the issue of paper money or digital money is just a change of form< In addition, Huang Zhen mentioned that the issue of digital currency is still in the stage of discussion, which is an innovative mechanism of currency value symbol, and many problems are still under study. However, in practice, people are more and more inclined to use e-banking and e-payment rather than carrying notes. Under this trend, the number of banknotes in circulation in the future may decrease
the central bank's issuing of digital currency is still inspired by encrypted digital currencies such as bitcoin and lettercoin, and so is the token of European crowdfunding platform. The digital currency issued by the central bank has monetary attributes, while the token of European crowdfunding platform can only be a kind of asset certificate, a niche proct.

2. Bitcoin is an electronic currency proced by open source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin.". Short for: BTC
bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions have risks. You can invest cautiously. You can search online for fire coin, coin security, OK, dobby trading platforms, etc. all of which can trade bitcoin. These are relatively large trading platforms, investing in mainstream digital currencies, and Don't invest in counterfeit money or air money.

The digital currency developed by the central bank has such a definition: encrypted digital string representing specific amount guaranteed and signed by the central bank . In a broad sense, digital currency includes a wide range of aspects, including electronic currency, virtual currency and legal digital currency. But strictly speaking, the digital currency developed by the central bank refers to legal digital currency
electronic currency is the digitalization of legal tender, including our common bank cards, Internet banking, electronic cash, Alipay and so on. No matter what the form of these electronic money is and through which institutions it circulates, its original source is the legal money issued by the central bank
In contrast, virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, Tencent Q coin and other game coins, such virtual currency is mainly limited to circulation in a specific virtual environment; Bitcoin, for example, solves the problem of decentralization and distrust through blockchain technology, realizes global circulation, and is sought after all over the world. In other words, virtual currency can only be closed in the network circulation, and digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegalthe digital currency researched and issued by the central bank is indexed RMB, which belongs to legal encrypted digital currency from the perspective of national schemes, and it is not only a payment tool but also a currency itself< the purpose of digital currency issued by the central bank is to replace physical cash, rece the cost of traditional paper currency issuance and circulation, and improve the convenience and transparency of economic transactions
hope to adopt
4. If you want to invest in digital currency, it is recommended to use Chinese currency. In the group chat of tens of thousands of people, you can send these questions in real time. I believe it will be faster and more convenient to know the answers than on the Internet. Hope to help you.

6. It is reported that the central bank's research on the issue of digital currency is not a temporary move. Since 2014, the research on the central bank's digital currency has been carried out for five years. In 2017, the digital currency Research Institute of the people's Bank of China was officially established, and has applied for more than 70 patents related to digital currency technology< In recent years, with the development of Internet technology, especially blockchain technology, many so-called "virtual currencies" have emerged in the world, such as bitcoin and Laite currency, which are controversial in recent years. So, how is the digital currency proposed by the central bank different from these commercial "virtual currencies"? The following is an analysis of the patent of Xiaoju
some patents of the digital currency Research Institute of the people's Bank of China (data source: huijuyun)
what is digital currency? --[ Invention patent] digital currency system
cloud computing is the mainstream direction of the future back-end server, and the digital currency back-end system adopts cloud based solutions
in e-commerce activities, e to different roles, the requirements for digital currency are different: customers require digital currency to be easy to use, safe to store and anonymous; Businesses require digital currency to be certifiable and can be converted into real currency; Banks require that digital currency cannot be illegally used or forged. Therefore, digital currency d-rmb should have the following characteristics:
1. Security: it can prevent any party in business from changing or illegally using digital currency< 2. Non repeated spending: digital currency can only be used once, and repeated spending can be easily detected
3. Controllable anonymity: banks and businesses collude with each other and can't track the use of digital currency, which requires that the system can't link the purchase behavior of e-cash users, so as to conceal the purchase history of digital currency users, but the issuer of digital currency can track the use of digital currency
4. Unforgeability: digital currency that users cannot fake
5. Fairness: the payment process is fair, which ensures that either the two parties succeed in the transaction, or both parties have no losses, so as to prevent one of the parties from suffering losses in the transaction
6. Compatibility: the issue process and circulation of digital currency in d-rmb system should refer to the issue and circulation of physical currency as far as possible
as for digital currency, it should be able to adapt to various use scenarios of existing currency and be freely convertible with existing currency
this patent provides a digital currency system, including central bank digital currency system, commercial bank digital currency system, and authentication system
among them, the central bank's digital currency system is used to generate and issue digital currency, and to register the ownership of digital currency; The digital currency system of commercial banks is used to perform banking functions for digital currency; The authentication system is used to provide authentication for the interaction between the central bank digital currency system and the terminal equipment used by the users of the digital currency, and for the interaction between the central bank digital currency system and the commercial bank digital currency system
