1. When will the central bank’s digital currency be launched?

The research and development of the central bank’s digital currency has achieved initial results. After multiple rounds of testing, on January 4, 2022, The pilot version of the digital RMB APP has been launched. When using the digital RMB APP, you need to select an operating institution during the activation process. There are 9 options in total: ICBC, Agricultural Bank of China, Bank of China, China Construction Bank, Bank of Communications, Postal Savings Bank, China Merchants Bank, MYBank (Alipay), and WeBank (WeChat Pay).
Extended information:
Digital currency:
According to Reuters, the Swedish Central Bank (Riksbank) said last week that it has begun testing the electronic version of the krona (e-krona). If the e-krona later enters circulation, it will be used to simulate everyday banking operations, such as payments, deposits and withdrawals through digital wallets such as mobile apps. The Riksbank said it will use blockchain technology to first simulate the use of electronic krona in an "isolated test environment." The test will last until February 2021. The purpose of the project is to show the general public how to use electronic krona. However, the Riksbank has not yet made a final decision on whether to issue an electronic krona.
It is understood that in 2018, the Swedish government began to call for the launch of an e-krona pilot program, with the goal of starting to implement digital cash in 2021. Sweden is indeed the country with the lowest dependence on cash in the world. The e-krona test project may become a learning case for other hesitant central banks to test the reaction and acceptance of ordinary people.
In addition, we can see that in an environment where cash dependence continues to decline and alternative currencies such as corporate coins are successively launched, central bank digital currency has become an inevitable trend. The global central bank digital currency project has entered a channel of accelerating research and development and implementation. In the past two years, central bank digital currencies of major countries in the world are likely to be tested.
It is worth noting that if digital currency, which has become increasingly popular recently, is widely used in the future, it will inevitably have a profound impact on the financial system. The director of the Digital Currency Research Institute of the People's Bank of China revealed that since the launch of digital currency research in 2014, the central bank's digital currency (DC/EP) has basically completed top-level design, standard formulation, and testing. In the next step, it is necessary to rationally select pilot verification areas, scenarios and service scopes, continuously optimize and enrich the functions of digital renminbi, and steadily promote research on the introduction of digital forms and legal tender. He further emphasized that the digital currency developed by the central bank is essentially the digitization of the RMB, and we must adhere to the principle of "not speculating on currency." Talking about how to supervise crypto assets such as Bitcoin and Ethereum, he said that it is still necessary to follow the clear regulatory requirements of the "Announcement on Preventing Token Issuance Financing Risks" previously issued by the central bank and other seven ministries and commissions.

6. The two giants of blockchain mining machines have successively submitted applications for listing in the United States and are desperately trying to seize the "window" to see if they can do so

Reporter from China Times (chinatimes.net.cn) Yang Liu, Hu Jinhua, and Wu Min reported from Shanghai and Beijing

The trend of the blockchain industry has begun to become clearer as the country issues clear encouragement signals. Canaan and Bitmain, the two major domestic mining giants that have been struggling to go public, seem to have grasped "life-saving straws."

"China Times" reporters learned that on October 28, the U.S. Securities and Exchange Commission announced the IPO documents of chip mining machine manufacturer Canaan Yunzhi. The documents showed that Canaan Yunzhi's plan to raise funds was insufficient. It exceeded US$400 million, which was smaller than the US$1 billion raised during the failed IPO in Hong Kong. This is also the fourth time that Canaan has sought financing channels from overseas capital markets after several unsuccessful IPOs in Hong Kong. .

On the other hand, Bitmain, as the world's largest cryptocurrency mining company and a competitor of Canaan in the mining machine and AI chip markets, is staged a "CEO revolt." Just on October 29, Wu Jihan, the co-founder of Bitmain, publicly announced at an all-employee meeting that he would terminate all positions of Bitmain’s legal representative and chairman Ketuan Zhan, who started the business together. The two founders completely broke up. .

On October 30, new news came out of Bitmain. According to reports from self-media in the relevant industry, one week before Wu Jihan launched this "coup" raid, Bitmain had secretly submitted a listing application to the SEC, and the sponsor was Deutsche Bank. This process has been led by Jihan Wu and CFO Liu Luyao, another senior executive of Bitmain, with Ketuan Zhan less involved. In this regard, our reporter also called the relevant departments of Bitmain, but Bitmain declined to comment.

"Both Canaan Ventures and Bitmain have been on the road to IPO in the past two years, but the road ahead is bumpy. Due to the cold winter period in the mining industry, the mining companies of these two institutions have The machine business is deteriorating, and the capital chain is even tighter. Now that the country’s favorable policies have been introduced, there is no doubt that both institutions have begun to rush into the US stock market. Compared with the two capital markets of the mainland and Hong Kong, Canaan has always been cautious about such business, so Canaan It is almost impossible for Yunzhi and Bitmain to be listed in Shanghai and Hong Kong. The US stock market is relatively loose. For Bitmain, Wu Jihan’s strong return means that if it obtains shareholder support, Bitmain will focus on the areas with the most advantages. The blockchain industry has regrouped in the mining machine and mining pool business and launched an impact on the US stock market." October 3On the 0th, Liang Ming (pseudonym), an investor in the mining machine business in Shanghai, told a reporter from the China Times.

The future of the second "mining company" to go to the United States for IPO is uncertain

Compared with the turbulent Bitmain, Canaan is one step ahead, attacking the IPO for the fourth time and submitting a U.S. stock prospectus .

According to Canaan’s disclosure in the prospectus, the company started by producing Bitcoin mining machines and is the world’s second largest Bitcoin mining machine manufacturer. In the first half of 2019, its mining machine sales were According to calculations, the company's market share in the first half of 2019 was 23.3%, ranking second in the world, and Bitmain's market share was 64.5%, ranking first.

According to public information, as the world's second largest manufacturer of Bitcoin mining machines, Canaan's Avalon mining machine was launched in 2013, which is a commercial ASIC chip Bitcoin mining machine. Bitcoin "miners" bid farewell to the original era of computer CPU and GPU mining and chose high-power ASIC chip mining machines.

In 2015, due to Bitmain’s dominance of the mining industry with its S7 Antminer and subsequent S9 mining machines for many years, Canaan’s new series of mining machines was late in losing its first-mover advantage. In July 2018, Canaan released the Avalon A9 series, which was earlier than Bitmain’s launch of 7nm technology ASIC chip mining machines. Due to the low price of the virtual currency market, Canaan's efforts to make a comeback have had limited success this time.

Reporters found on Canaan’s official website that the Avalon A1166 is currently priced at US$1,978. The A11 series of Avalon A1146, A1066, A1047, A1026 and other mining machines are also on sale.

According to sources in the mining market, Canaan recently released the Avalon A1166, which has a computing power rating of 73TH/s and an energy consumption ratio of 46J/T. A1166 is Canaan's best mining machine at present. Based on the current Bitcoin price and mining profits, the time to pay back the investment is about 230 days.

It is worth noting that in this prospectus, Canaan listed Bitcoin price as the first risk factor. Due to the downturn in currency prices and the sharp fall in mining machine prices, Canaan Yunzhi achieved revenue of 289 million yuan and a net profit loss of 331 million yuan in the first half of this year. Compared with the net profit of 216 million in the first half of 2018, the profit dropped by 252% year-on-year.

“The price of Bitcoin controls the fate of major mining machine manufacturers, and the symbiotic nature is very obvious. Mining machines not only consume electricity, but their mining costs are also affected by the dry and wet periods of hydropower. "On October 28, a mining machine manufacturer in Sichuan said in an interview with a reporter from China Times.

The prospectus shows that the funds raised from this IPO will be used for the research and development of AI algorithms and application-related ASICs, and the company’s future revenue growth will depend on whether it can successfully open up AI. markets and enter new application areas.

That isHe said that in addition to mining machine sales, Canaan is also working hard in the field of AI algorithms and applications, trying to transform into an AI chip manufacturer.

The mining machine boss also went public after the internal battle

In fact, as the development of China’s blockchain industry has been elevated to a national level, recently in the mining machine industry, especially the two major What happens to the giants is really confusing to the outside world.

Since the "second eldest" Canaan and Zhizhi have chosen to go public, why can't Bitmain, the boss, go public, even though it is currently involved in a battle for management control?

In an important notice issued to employees by Bitmain co-founder Jihan Wu on October 28, he decided to terminate Micree Zhan from all positions in Bitmain, effective immediately. It also stated that any employee of Bitmain shall no longer carry out Micree Zhan’s instructions and shall not participate in meetings convened by Micree Zhan. If there is any violation, the company will consider terminating the labor contract depending on the severity of the case; if it causes damage to the company’s economic interests, the company will pursue civil or criminal prosecution in accordance with the law. responsibility.

There is more news that Wu Jihan subsequently sent another email announcing the dismissal of Wang Zhi, the current head of HR. Wang Zhi was appointed by Ketuan Zhan and seems to be very unpopular within Bitmain. Micree Zhan is currently prohibited from entering the company's office, and employees are prohibited from continuing to follow instructions, which is equivalent to being expelled "out of the country."

A reporter from "China Times" also reviewed the development history of Bitmain and found that the main operating entity of Bitmain is Beijing Bitmain Technology Co., Ltd. The predecessor of Bitmain was founded by Ketuan Zhan, Wu Jihan was a latecomer, and the circle Nei has always believed that Ketuan Zhan is the real operator of Bitmain.

In August 2018, Bitmain went to Hong Kong for its IPO. According to the prospectus at the time, Ketuan Zhan held 36% of Bitmain’s shares and was the largest shareholder; Jihan Wu held 25.25% of the shares and was the second largest shareholder. No one has absolute control.

According to analysis by insiders, the root cause of the split between the two parties is the disagreement between the two founders on the company's business line. The core is their different opinions on whether to develop the AI ​​chip business. Wu Jihan prefers to do mining machines and mining, while Zhan Ketuan prefers to do technology and lead Bitmain's AI projects.

Public reports show that in March this year, Wu Jihan had distanced himself from the management of Bitmain.

At that time, Wu Jihan led some core technical personnel to create a new company dedicated to the construction of blockchain infrastructure. Its business included digital currency exchanges, mining pools, etc. It is reported that Bitmain has also invested in Wu Jihan’s new company, while Wu Jihan continues to hold shares in Bitmain. After Wu Jihan "established a new business", Bitmain's business mainly focused on AI chips and mining machine chips, with Zhan Ketuan fully in charge.

However, there are already clues that Wu Jihan can make a comeback this time.

According to Qichacha’s information, on October 28, Beijing BitmainTechnology Co., Ltd.'s legal representative has been changed from Ketuan Zhan to Jihan Wu, and Wu Jihan has also succeeded Ketuan Zhan as executive director. Ketuan Zhan has resigned as executive director and continues to serve as manager.

According to a Bitmain insider, in terms of Bitmain’s development direction, except for Kai-fu Lee, most shareholders within the company almost all support continuing to do business related to blockchain, especially mining machines. Business, this is what Wu Jihan has always insisted on. Spurred by previous rivals' submission of prospectuses, shareholders supported Wu Jihan's rise to power, and their primary purpose was to promote Bitmain's listing in the United States.
