Total amount of ATT digital currency
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
China: actively and steadily promote the implementation of the research on the central bank's digital currency
as early as 2014, the central bank set up a special research group on the issue of legal digital currency to demonstrate the feasibility of the central bank's issue of legal digital currency< On October 28, 2019, Huang Qifan, vice president of China Center for international economic exchange, said: "the people's Bank of China has studied DC / EP for five or six years, and I think it has become mature. The people's Bank of China is likely to be the first central bank in the world to launch a digital currency. "
on November 28, fan Yifei, vice governor of the people's Bank of China, said at the forum that at present, the central bank's legal digital currency DC / EP has basically completed the top-level design, standard formulation, function research and development, joint debugging and testing under the premise of adhering to double-layer delivery, M0 substitution and controllable anonymity. In the next step, we will follow the principle of steady, safe and controllable, reasonably select the pilot verification area, scene and service scope, continuously optimize and enrich the DC / EP functions, and steadily promote the introction and application of digital legal tender< European Central Bank: exploring the form and possibility of CBDC. 'we are analyzing what form CBDC may take in order to achieve its potential purpose and mitigate its potential negative impact on monetary stability and financial intermediation,' Mr. kindos said. On the stable coin, Mr jindos said that it was very uncertain whether the stable coin could deliver on its promise, and it was clear that it could bring risks to consumers and the financial system. So it is understandable that authorities around the world are calling for regulatory stability.
Digital assets att refers to the non monetary assets owned or controlled by enterprises or indivials in the form of electronic data, which are held in daily activities for sale or in the process of proction
the network accounting, office automation, electronic payment system platform in the network era make the current mode of proction have incomparable advantages compared with the traditional mode of proction, but in real life, they only rely on magnetic media and exist a series of codes. Although they are digital commodities, they reflect the nature of assets, so they are called digital assets att
extended data:
att features of digital assets:
1. High price. Because these application software with special purpose is specially developed for a specific work, its cost is higher, and its price is not lower than the price of fixed assets
(2) strong attachment. Application software must be supported by computer hardware and system software in order to play its role3. Strong interaction. Even the simplest application software also has some interactive functions, such as the error prompt to the operator, which is the most basic advantage of IT instry procts
The quantity is infinite. Digital assets as assets are scarce (because not all enterprises or indivials can create digital assets), but its supply can be unlimited. However, tangible assets are always limited e to the limitation of property and storage space Cost decreasing. The proction cost of tangible assets is positively proportional to the proction quantity. Due to the unlimited output of digital procts, the development cost is allocated to the output according to the traditional financial accounting method, so the cost of digital procts is lower and lower with the continuous expansion of sales volumesource: network digital assets
is it a reliable currency? Just compare it with the mainstream currencies such as bitcoin, Leyte, decent and ether.
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.
in addition, the power consumption of the mining machine is very serious. If you turn on the machine 24 hours a day, you may not be able to earn back the electricity bill at home
Mining studios are usually built in remote places where there are private small hydropower stations, because the electricity price of private small hydropower stations is low.
