extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

extended data:

related extension: blockchain financial application:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035

3. At the beginning of the blockchain, I was confused and went to all kinds of communities and wechat groups to read all kinds of CSDN, but I think the more professional ones are Babbitt, Ethereum Chinese network, understanding basic knowledge, and a forum called lookbc, which specializes in blockchain. It's quite good. There are a lot of sections, and there are all kinds of white papers. The information is very full and the activity is high, I see it from there now

Do you want to know about blockchain or digital assets
it is suggested that the blockchain platform can join the network, CSDN, Tianya and other blockchain community post bars
if it is about digital assets, it can join the bit-z community bit-z network

5. There are many blockchain platforms in China. Let me talk about one I have heard of. Seems to be called dig chain network, you can search to see Oh, take it!

6. As a blockchain browser, gikee is a tool for monitoring, browsing and visualization of blockchain digital assets. The capture and analysis of gikee data are from multiple perspectives, including project information, circulation status, transaction cost, transaction relationship, asset distribution, asset relationship, asset change, address tracking, currency holding trend, etc
therefore, gikee can not only see the data on the chain, but also obtain the project details and change information in the form of visualization. You can also see the push of messages on the chain from the gikee.

7. There is a big difference between foreign and domestic mining machine settings. It is suggested that mining machine settings should be in foreign countries, but not in China.

8. Since the server is under the control of the United States, is it really safe for China to engage in digital currency? This issue of security is assessed by the state, which may not need your consideration. Moreover, I think the state has its own plan to develop financial currency, especially digital currency

9. The difference between DAG blockchain and traditional blockchain is that the latter requires miners to complete proof of work (POW) to execute each transaction, and DAG blockchain can get rid of the restriction of blockchain to complete such operation. On the contrary, in the DAG blockchain, one transaction is followed by another, which means that one transaction can provide proof for the next transaction, thus ranking all the time. The connection between these transactions is DAG, just like blocks provide their names to the whole blockchain through hash value

in the traditional blockchain, each transaction takes a lot of time, while for DAG blockchain, the transaction time will become negligible

10. Obviously, it's a hoax, a hoax of pyramid selling under the guise of blockchain. Don't charge money to be a member!! Don't charge money to be a member!! Don't charge money to be a member!! The reason is to be a platinum member of 299. It's literally one year, but actually only one month. Why? Because there is no contribution value in the second month, the income will drop to 10%, that is, the income of only 30e drill every day. According to the current one dime of an e drill, it costs 3 yuan a day and 90 yuan a month (converted into RMB in the future, it will be lower and lower, even collapse). The prices of the goods on the mall are all very high, and the things that cost more than 10 yuan on Taobao are marked with more than 100 yuan, The premium is ten times. In short, you are a member and you are mining every day. After a month and a half, you can change something worth more than ten yuan. Listen to me and decide whether you want to be a member or not. Then I'll tell you about their current routine. Why did they say that there was no contribution value in the second month, and the income would drop to 10%? Because they are going to launch Diamond members, so they use contribution value to abolish Platinum members, and contribution value is only obtained by pulling the head, which means that if you don't help him pull the head, you charge 299 for nothing, which is naked MLM!! What's more, the current situation of their exchange mall is that all the goods in it are out of stock. Even if you have more e-diamonds, you can't exchange things
