Total mth of digital currency

1.

The total number of bitcoins is 21 million

in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

monetary characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

Digital money (electronic money or electronic currency) is a kind of money in digital form (different from paper money and coins)

it shows properties similar to physical currency, but it can allow real-time transaction and borderless ownership transfer. Examples include virtual currency, cryptocurrency and currency issued by central bank and recorded in computer database (including digital base currency)

like traditional currencies, these currencies may be used to purchase physical goods and services, but they may also be restricted in some communities, such as online games

digital currency is the currency balance that is electronically recorded on stored value cards or other devices. Another form of electronic currency is network currency, which allows value transfer on computer network, especially on the Internet. E-money is also a creditor's right to other financial institutions such as private banks or bank deposits

digital money can be centralized, that is, it has a central point to control the money supply, or it can be decentralized, that is, the control power can have different sources

3. It shows that the total amount of this kind of digital currency is relatively large, and the total amount of many digital currencies is as high as 10 billion. The circulation of some MLM coins is not constant and can be increased or split at will. Moreover, there are many different digital currencies in the world, and the number of each digital currency is very considerable
the well-known digital currencies in the currency circle include bitcoin, Ruitai coin, Laite coin, doggy coin, etc.

4. Chinese digital currency should refer to Chinese currency, the specific amount of this currency is not clear. However, many things of this kind of coin are fabricated, not real. And its related companies are mostly forged. Now the Chinese currency has basically disappeared, it is estimated that it should be dead

is it a reliable currency? Just compare it with the mainstream currencies such as bitcoin, Leyte, decent and ether.

5. The total amount of money in DCEP is not constant

why

let's take a look at the current definition of DCEP

Digital legal tender

in addition to being different from legal paper money in carrier, it has the same function as paper money: value scale, circulation means, payment means and value storage

this is also the function of paper money

the issuance of DCEP is based on 100% reserve and will circulate with cash currency, that is, M0 issuance

although the central bank's digital currency was slowly launched after the rise of blockchain technology, it is not pure blockchain technology, but only uses some technologies related to blockchain

we all know that the commercial application of block chain technology still faces many problems, such as concurrency, data storage and so on

a country with a large population like ours, if we use blockchain technology in a strict sense, it will not be able to carry it at present<

Wanxiang blockchain analysis:

from the information disclosed by the people's Bank of China, DC / EP does not use the real blockchain like Libra

although digital currency is not a token in the blockchain, it is similar to the token in the blockchain in the key features of non double flower, anonymity, unforgeability, security, transitivity, separability and programmability

therefore, DC / EP still belongs to token paradigm rather than account paradigm

the central bank is responsible for the maintenance of the DC / EP issuance registration subsystem, which is centralized and does not need to run consensus algorithm, so it will not be subject to the performance bottleneck of the blockchain

in DC / EP, blockchain is used to confirm the right registration of digital currency and plays an auxiliary role

each country's base currency issuance is increasing every year

therefore, the central bank's digital currency improves the bearing property of money. Paper money is naturally suitable for the atomic world, and digital currency is more suitable for the consumption scenarios in the bit world

the supply is definitely the same as that of the previous monetary system, increasing every year.

6. In the final analysis, e-money is just conceptual money information. It is actually a special information composed of a group of data including the user's identity, password, amount, scope of use, etc., so it can also be called digital money; 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 a kind of invisible currency based on highly developed electronic technology; It 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, which can be paid on the Internet or through other electronic communication methods. This kind of currency has no physical form and is the holder's financial credit.
whether electronic currency can be called currency depends on whether electronic currency can independently perform the function of currency. At present, e-money can play the role of payment and settlement, but e-money is only a quasi currency that may perform the function of currency.
e-money can be divided into two types: one is e-cash based on the Internet environment 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 system
therefore, from an economic point of view, the use of e-money can indeed rece the circulation of paper money

8. "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 package is composed of data code and identification code. The data code is the content to be transmitted, while the identification code indicates where the data package comes from and goes Definition of digital currency: the alternative currency in the form of electronic currency belongs to digiccy. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. 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, or can be transferred, stored or traded in electronic form. 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.
