⑴ Is the popularity of blockchain a hype?

Recently, the virtual digital currency market has become popular, and blockchain technology has also become popular. At present, many ministries and commissions such as the Ministry of Industry and Information Technology and many industry giants at home and abroad have established specialized teams or laboratories to actively promote research on blockchain technology and its applications.

On October 13, 2017, the General Office of the State Council issued the "Guiding Opinions on Actively Promoting Supply Chain Innovation and Application" and proposed that relevant enterprises study the use of blockchain, artificial intelligence Use emerging technologies such as intelligence to establish a credit evaluation mechanism based on the supply chain. Promote the organic docking of various supply chain platforms and strengthen the disclosure and sharing of information such as credit ratings, credit records, risk warnings, illegal and untrustworthy behaviors.

At present, not only many financial institutions, related enterprises, and scientific research teams are actively investing in researching blockchain technology, but many ministries and commissions, including the Ministry of Industry and Information Technology, have also set up specialized teams or laboratories to actively promote blockchain technology and its applications. Research.

The market generally believes that blockchain technology is expected to further develop in the following aspects.

——In the financial field, it can record all transaction party information, process steps, time series and other core information in financial transactions, and ensure the authenticity and non-tamperability of the information.

——Supply chain management can record the status of goods and the flow of funds in real time to ensure the authenticity of transactions. Improve supply chain transparency while effectively preventing counterfeits from entering the market.

——Food safety management, large supermarket chains can use data blockchain technology to track the origin of food, improve food traceability, and track and review the production and transportation process of food at a lower cost.

——Media and public communication, in the Internet public opinion environment, can use blockchain technology to trace the source of information, confirm the authenticity and accuracy of information, and inhibit the production and dissemination of false information.

However, Qin Yi, Deloitte Asia Pacific investment management industry leader, believes that the current large-scale application of blockchain technology is lower than expected. Further breakthroughs are needed in terms of establishing a data open alliance system, ecosystem construction, and Internet of Things application support. In particular, the strong demand for data openness caused by the "decentralization" characteristics of blockchain technology is full of resistance.

Strengthen supervision of "buying a casket for a pearl" type of speculation

Blockchain technology has attracted a wave of investment, and the virtual digital currency transactions associated with it are "hot like hell." This attracted great attention from the financial regulatory authorities, and at the beginning of the new year of 2018, they issued three articles in a row, pointing directly at virtual currencies.

As early as September 2017, seven ministries and commissions including the People's Bank of China issued an announcement clearly stating that token issuance financing is essentially an unapproved and illegal public financing act. From now on, the issued ICO (Initial Coin Offering) projects must be liquidated, and new projects are not allowed to be reissued.

Entering 2018, on January 2, the leading group for the special rectification of Internet financial risks issued a document requiring all localities to guide enterprises within their jurisdiction to withdraw in an orderly manner.Launched the "mining" business and regularly reported work progress; on January 12, the China Internet Finance Association issued a risk warning to prevent ICO activities and named Xunlei's "Wankebi". On January 17, the Business Management Department of the People's Bank of China issued a notice requiring all legal person payment institutions within its jurisdiction to carry out self-examination and rectification work immediately, strictly prohibit providing services for virtual currency transactions, and take effective measures to prevent payment channels from being used for virtual currency transactions.

“There is no necessary connection between the development of blockchain technology and digital currency. Digital currency is just one of the application scenarios of blockchain technology.” Guo Feng believes that blockchain is a pearl, while digital currency is just a Box. The reason why the hype of virtual digital currency is out of control is because some people think that the "box" is exquisite, the price is opaque, and the profit can be higher than that of the "pearl". "This is a typical 'buying a casket for a pearl'."

"Monitoring and managing risks does not mean that we reject innovation." Yang Dong, director of the Financial Technology and Internet Security Research Center of Renmin University of China, believes , as a technical tool, blockchain is technology neutral and does not directly involve financial and legal risks; the current shutdown of the virtual digital currency trading platform does not conflict with the current vigorous development of blockchain.

Those who need it will pay attention, and those who don’t will not be fooled.

⑵ Bitcoin has exceeded the US$58,000 mark. Do you know what Bitcoin is?

Bitcoin has exceeded the US$58,000 mark. Bitcoin is just a string of digital symbols and does not generate any profit itself. , the real value of Bitcoin lies in blockchain technology. The reason why Bitcoin has risen so much is because blockchain technology may change the Internet landscape and become a breakthrough for the future Internet. The unique technology of blockchain allows Bitcoin to have the function of preserving value and Financial attributes, this is the charm of Bitcoin.

As an emerging industry, Bitcoin has been pursued by many people. The greatest value of Bitcoin lies in its blockchain technology. The uniqueness of blockchain technology makes it a breakthrough direction for the future of the Internet. Bitcoin itself does not generate any profits, but its reliance on blockchain technology makes it unique. This scarcity is a reflection of its value. Bitcoin is actually a series of digital symbols, which give more Meaning, such as value preservation function, financial attributes, scarcity and lack of supervision are its advantages and characteristics.

3. What exactly is Bitcoin?

No one has ever seen Bitcoin, because Bitcoin is a virtual currency that does not exist in real life because no one supervises it and no one can control it. It is just a string of digital symbols. A product traded in the blockchain is fictitious and does not exist. This is Bitcoin, a thing that appears based on everyone's imagination.

⑶ Where is the customer service of zt exchange?

According to the plan of the National Information Center, the Blockchain Service Network (BSN) has completed the half-year internal testing period and launched on April 15 Commercial use will officially enter the global commercial stage on April 25. According to the latest released "District"Blockchain Service Network Basics White Paper", with the popularity of BSN in countries around the world, it will become the only global infrastructure network currently innovated by China, and its gateway access is controlled by China.

Affected by the good news, blockchain-related concept stocks are highly sought after by the market.

According to statistics, there are currently 143 listed companies in the A-share market involved in the blockchain technology industry, with a total market value of 2 trillion yuan. As of April 24, the A-share blockchain sector had a cumulative increase of 6.65% in April.

Some blockchain concept stocks have become the targets of centralized recommendations by institutions. Statistics show that in the past 30 days, 10 blockchain concept stocks including UFIDA Network, Halo New Network, China Unicom, Suning.com, Yuxin Technology, China Micro, Radio and Television Express, Hang Seng Electronics, Xinkaip, and Donggang Shares have been listed. The number of times the institution has given bullish ratings such as "buy" or "overweight" is no less than 5 times.

⑷ The reason why more than 20 companies have been regulated for "taking advantage of" blockchain hot spots

The popularity of blockchain continues, and it is not uncommon for listed companies to attempt to "take advantage of hot spots". Among them, Many listed companies have attracted regulatory attention. On March 19, Yinjiang Co., Ltd. issued an announcement stating that it had received a letter of concern from the Shenzhen Stock Exchange, requesting clarification on whether there was any motive for speculating on the hot concept of blockchain to speculate on the stock price.

The relevant regulatory authorities of the Shanghai Stock Exchange attach great importance to this and organize analysis and judgment as soon as possible. According to the analysis of the Shanghai Stock Exchange, some companies are suspected of actively "posting hot topics" and self-announced that the company's business scope involves "blockchain", typical examples are Youjiu Games and Shangying Global.

In response, the Shanghai Stock Exchange adopted a morning emergency suspension of the company's shares and issued a letter of inquiry to the company, requiring the company to explain in detail whether it caters to market hot spots, whether relevant behaviors are in violation of regulations, and to fully warn of risks and verify insider information. trade.

⑸ Why is blockchain not a “panacea” for all economic activities?

Recently, the most eye-catching thing that has appeared frequently in major public opinion media is undoubtedly the blockchain chain.

Third, blockchain data is completely open and transparent. If anti-anonymous identity screening technology is developed in the future, a user’s information can be seen through password cracking, and some key targets Location and identification are also possible, posing threats to data security and personal privacy.

Fourth, supervision is still on the way. Decentralization means that the main body is not clear, which also brings great difficulty to supervision; especially regulators under blockchain technology will face "a huge amount" data, it is difficult to regulate the transparency of information and achieve precise supervision. In addition, the vacancies and lag in the regulatory legal system have resulted in the lack of necessary institutional norms and legal protection for blockchain applications, increasing market risks.

Obviously, blockchain technology is not a "safe box" that ensures the absolute security of the financial industry and other economic activities, nor can it serve all economies.The “panacea” of activity. Whether they are companies involved in the research and development and application of blockchain technology, or investors involved in investment in blockchain-related industrial projects, they should maintain a cautious and rational attitude.

⑹ Which companies are related to the blockchain hype craze?

Many listed companies rushed to clarify the blockchain hype craze

In the past week, the district Blockchain concept stocks have set off a wave of speculation in the A-share market. Individual stocks have continued to rise by the daily limit. Dozens of listed companies have issued announcements. Some have clarified related businesses, while others have "coincided" with the blockchain concept intentionally or unintentionally.

In addition, dozens of companies including Aikang Technology, Donggang Co., Ltd., Shenzhou Taiyue, Hailian Jinhui, and Boss Software have also issued announcements. Wind statistics show that since this year, the Wind blockchain concept index has increased by more than 15.89%. In overseas markets, stocks involving the blockchain concept have skyrocketed overnight. On January 4, Chinese concept stock ChinaNet Online announced that it would implement blockchain technology applications. The stock soared 698% overnight. Taking 2018 as the range, the cumulative increase in the stock in just nine trading days has reached 340.37%.

It is reported that although the industry generally recognizes the potential of blockchain technology, as far as many listed companies in the A-share market are concerned, it is still at a relatively preliminary level. In response to the market's hype about the concept of blockchain, in the past week, the Shanghai Stock Exchange has issued letters of inquiry to Shangying Global and Youjiu Games, requiring them to disclose the research progress, commercial application scenarios and profit models of blockchain technology, and Combined with the current maturity of marketization and commercialization of blockchain technology, investors are fully warned of risks.

⑺ Binance’s price increase and decrease is incorrectly displayed

Binance’s price increase and decrease is incorrect because Binance uses the price at 8 a.m. and calculates the increase and decrease within 24 hours. , the calculation time is different, so the rise and fall are different. Virtual currency trading rules: execute T 0 transactions, there is no price limit, two-way trading, you can do more and sell more, you can also do margin trading, trading time: 24 hours a day. Cryptocurrencies are highly risky and are not recommended for ordinary investors.
1. Definition of Binance
Using currency depreciation as a blockchain trading platform is a comprehensive blockchain ecosystem. The founder, Changpeng Zhao, aims to become the basic builder of the blockchain world and promote blockchain development of the chain industry and the free circulation of value. Currency Safety Network operates a blockchain asset trading platform. BNB - Currency Depreciation Coin [2] is a blockchain currency that was underestimated by the market when it was first issued. In October, the price of BNB was 10 yuan per coin, and 986,000 BNB were destroyed. Since they account for 20%, that translates to roughly $7 million in profit in U.S. dollars. The price in October 2018 fluctuated around 57 yuan.
2. Calculation of Binance’s 24-hour increase
The first step is to click to open the “24-hour increase” calculation form.
In step 2, enterThe number of the expression "=".
The third step, next subtract "yesterday's 8am price" from "today's 8am price".
Step 4, divide by "the price at 8 a.m. yesterday".
The fifth step, after finally pressing the "Enter key" to confirm, it is calculated that the increase will increase by 30% within 24 hours. This is calculated.
Because trading cryptocurrencies is different from stocks. Stocks have opening times and withdrawal times, but not in cryptocurrencies. Cryptocurrency trading continues 24 hours a day, 366 days a year. The opening of A-shares is the working time of the Chinese, the opening of the US stock market is the working time of the Americans, and the cryptocurrency market is the whole world. Therefore, some platforms use UTC as the starting point for getting closer, which is 8 a.m. Beijing time. The default daily opening time for currency depreciation is 8 am Beijing time. However, Binance shows that drop compared to 24 hours ago. Therefore, Xiaolan looked at the Binance K-line and saw that it might have fallen compared to 8 a.m., but she might have been on a business trip 24 hours ago.

⑻ How about the Triporg travel blockchain project?

Triporg is a blockchain + travel service platform. Triporg provides hotel, air ticket, and train ticket booking services, connecting consumers and service providers through a series of smart contracts. Every Triporg user is also the owner of the platform. Personally, I feel it is worth understanding carefully and has great potential.

⑼ How to judge whether a blockchain project is worth investing in?

8. Reference blockchain project rating websites< /p>

Relatively reasonable, there are many rating websites, and the rating standards of each platform are also different. There may be a big gap in the ratings given by the same project on different platforms. At this time, we are needed

I have a deep understanding of the basic knowledge related to blockchain and am capable of certain self-judgment. Don’t trust experts. Many so-called experts may have interests tied to the sponsors of blockchain projects.

9. Direct communication

The last point is also the most important. Whether it is a face-to-face road show, or communication in a forum or community, people can intuitively understand whether the initiator of this project is reliable. Whether it is a blockchain product project or some technical questions, the project side can answer them. Whether it is reliable or not can be known once tested.
