Circulation of DIDP 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. The circulation and mining situation of virtual currency need to be recorded on the blockchain, and the information is tamperable and permanent. But the premise is that the operator should make the source code public, otherwise users can't see it. Therefore, a normal digital currency, open source code is necessary. The source code of bitcoin, lightcoin and decent was open at the beginning
there may not be such MLM currencies as Vicat and Baichuan.

The digital RMB red envelope of 10 million yuan issued by Shenzhen city has brought the development of e-money back to the people's vision

in fact, since April 2020, small-scale pilot projects of digital RMB have been carried out in Shenzhen, Cheng, Suzhou and xiong'an, and the pilot scale will be expanded to 28 provinces and cities in August 2020

as a socially recognized "super outlet", in addition to the high investment of digital currency related enterprises, its impact on the financial market is also of great research value

Policy evolution of the development of digital RMB

as early as 2014, the central bank has concted research layout on digital RMB, and discussed the development framework of digital RMB with major international financial institutions and research institutions in the 2016 digital currency seminar

after six years of development, China has initially developed the "pbctfp blockchain platform" and continuously promoted the pilot activities of digital RMB. It can be predicted that as today's technology and policy outlet, digital RMB will have excellent development prospects and extremely fast development speed in the next few years

Figure 1: Policy Evolution of digital RMB

with the improvement of China's national strength, digital RMB provides an opportunity to establish a "new system of RMB cross border settlement", which can promote RMB payment activities around the world and realize the internationalization of RMB

5. 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.

6. 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.

7. It may be that the computing power is not as good as others. They have been poached by others. Bitcoin has experienced the computer CPU mining - & gt; Computer graphics card mining - & gt; Professional mining machine mining several stages, now ordinary computer mining are more difficult, unless it is to invest in special mining equipment. But it's not worth it. Now mining is relatively professional, so is the flow of ore. It must be better for the professional miner, but if there is a buffer, the ordinary miner of flow ore can still dig.

8. Use Chinese, leave your email, send you some good Chinese trading website, remember to adopt

9. It seems that there is no relevant provisions in the law to protect the virtual property of online games
