Account based digital currency

1.

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

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

2. The people's Bank of China has designed a two-tier architecture for digital currency
specifically, according to Yao Qian, director of China digital currency Research Institute, the design framework of central bank's digital currency is mainly convenient and efficient, safe and controllable, and popular development
as for the two-tier framework, the two-tier framework is the central bank and the commercial bank, based on the account and wallet. This framework is to combine the original bank account system with the account system based on digital currency wallet
in blockchain technology, digital currency is separated from legal currency system and bank account system. Otherwise, together, it will cause chaos. Considering this problem, Yao Qian introced digital currency wallet into the account system of commercial banks. In this way, an account can manage both electronic currency and digital currency. Of course, this kind of design has a great impact on the current banking system, but it is also a resource for commercial banks with mature system
how does digital currency wallet work in commercial banks
bank accounts and digital currency wallets of commercial banks have common management features. In this case, bank accounts and digital wallets have different positioning. According to the wallet standard designed by the central bank, a wallet is equal to a safe deposit box. According to the requirements of customers, the bank will manage the safe deposit box as all the properties of cryptocurrency. This framework adds a Digital Wallet ID field to the bank account. In this way, the wallet has the function of a safe deposit box and does not participate in the business, so as to avoid affecting the core business of the bank
digital currency transfer can be directly transferred in the commercial banking system, or through the note issuing bank using the client-side digital wallet, direct point-to-point transactions, so that there is no need to rely on inter-bank payment between account banks< In a word, digital currency wallet is the personal wallet in the commercial banking system
theoretically, the payment system deals with demand deposits, while digital currency is in the category of cash
is the digital currency issued by the central bank decentralized
Yao Qian said that the biggest issue facing the instry now is whether decentralized distributed ledger should be used at the top level
Central Bank digital currency is more convenient and can develop into controllable anonymity through centralized issuance and account based weak association. However, in the digital world, we cannot confuse the economy and finance behind the numbers. Although they are all numbers, they represent different assets, so the central bank will keep them in mind when designing. We want to have a mature financial infrastructure for legal digital currency, but considering that the note issuing bank is only responsible for the digital currency itself, and the account bank is responsible for the actual management business, so as long as the specific application is implemented, the note issuing bank and the account bank will perform their ties and do their best
then the characteristics of the central bank's digital currency are
1. Digital currency, like RMB, has stable value
2. The operation mode is the same as RMB, which is endorsed by the national credit and issued by the central bank, and all commercial banks exchange it into the market
3. Digital currency issuance relies on big data, because it has the possibility of real-time collection of currency bookkeeping, flow, transaction, etc., which can provide help in anti money laundering
4. After digital currency replaces paper currency, it will play a positive role in preventing counterfeit banknotes, changing change, and preventing damage and loss ring transaction storage
5. It will rece the waste of resources. The proction and printing of paper money need cost, while the proction of digital currency depends on big data, so it will rece the waste of resources
therefore, with the advent of the central bank's digital currency, personal participation will have less opportunities to make money
I hope it can help you
hope to adopt it

3. Digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world

the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation

types of digital currency

according to different issuing or consensus mechanisms, it can be divided into four categories:

1, proof of work (POW)

proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk

3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state

4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC

according to the project type, it can also be divided into four categories:

1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin

2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont

3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)

4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.

4. Digital currency
unlike virtual currency, digital currency is neither bitcoin nor q-coin! That is to say, it is different from virtual currencies such as bitcoin and Ethernet
virtual currency can only be closed in circulation on the network, just like Tencent's q-coin and Huixin cloud software collaborative instry ecological chain platform, they can only be used for their own procts. 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 illegal digital currency. As for legal digital currency, there is no unified international definition. Yao Qian, deputy director of the science and Technology Department of the people's Bank of China and head of the preparatory group of the digital currency Research Institute, believes that the digital currency researched and issued by the people's Bank of China is indexed RMB. From the perspective of national schemes, it belongs to legal encrypted digital currency, which is not only a payment tool but also a currency. Correspondingly, virtual currency is also called illegal fixed digital currency. Li Lihui, head of the blockchain working group of China Internet Finance Association, once said that digital currency must have legal status, national sovereignty endorsement, and clear responsibility subject of issuance. Virtual currencies represented by bitcoin and ethereal currency have no country, no sovereign endorsement, no qualified issuers, and no national credit support. These are not digital currencies
digital money is not equivalent to virtual currency
since digital money can be used for commodity trading, is Alipay and WeChat payment a kind of digital currency?
Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. These are all payment methods based on electronic accounts, which are in essence just a process of informatization of legal currency, not digital currency in a strict sense. For example, the amount of Alipay or WeChat transactions is essentially banknotes on bank accounts, but it is electronic form. The "100 yuan" displayed on the mobile phone will correspond to the real 100 yuan in the bank.

5.

According to reports, the world's major central banks are focusing on digital currency. Some countries have clearly put forward the plan of issuing legal digital currency. For example, the central banks of Canada, the Netherlands, Australia, Russia and other countries have already announced the launch of digital currency research

different from the centralized delivery of traditional electronic payment instruments, the fund transfer of electronic payment instruments must be completed through the account, which adopts the account tight coupling mode, while the central bank's digital currency should be based on the account loose coupling mode, so that the transaction link's dependence on the account is greatly reced, and the central bank's digital currency holders can directly apply it to various scenarios, It is concive to the circulation and internationalization of RMB

According to the experts, digital currency was born in the existing financial system and will inevitably be affected by the existing payment system and information technology. Theoretically speaking, the payment system mainly deals with the demand deposit part of the broad money, while digital currency mainly belongs to the category of cash
