What is the total amount of DDM 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

Ethereum is the next generation of cryptography ledger. It intends to support many advanced functions, including user issuing currency, intelligent protocol, decentralized transaction and what we think is the first fully decentralized autonomous organization (Daos) or decentralized autonomous company (DACS) application

Ethereum does not specifically support every single type of function as a feature. On the contrary, Ethereum includes a built-in Turing complete scripting language, which allows you to write code for the feature you want to implement through a mechanism called "contract". A contract is like an automatic agent. Every time a transaction is received, the contract will run a specific code, which can modify the data storage inside the contract or send the transaction. Advanced contracts can even modify their own code

Ethereum was launched on November 1, 2015, and launched on August 22, 2016 on bitcoin trading platform, a well-known domestic trading platform; 30-¥ About 60, current: ￥ 1259.97, the rise is amazing

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. 500 kinds

5. 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.

6. 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.

7.

K is 100000, M is million

is usually distributed and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

low transaction cost compared with traditional bank transfer and remittance, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with cross-border payment which provides high handling charges to payment service providers

extended data:

according to the relationship between digital currency and real economy and real currency, it can be divided into three categories:

one is completely closed, has nothing to do with real economy and can only be used in specific virtual communities, such as magic world gold

Second, it can be purchased in real currency, but can not be converted back to real currency, and can be used to purchase virtual goods and services, such as Facebook credit

Thirdly, it can be exchanged and redeemed with real currency according to a certain ratio, which can purchase both virtual goods and services and real goods and services, such as bitcoin

8. Insur is a digital currency with a total circulation of 83.4 million and a circulation rate of 41.7%.
