『一』Will the limelight of blockchain overshadow artificial intelligence

Over 90% of blockchain talents have a monthly salary of more than 10,000 yuan

The average monthly salary per capita is 2.58 Ten thousand yuan in the limelight overshadows artificial intelligence and is accused of being a bubble

Since 2018, blockchain has been gaining momentum and has overshadowed artificial intelligence. According to data from the Boss Direct Recruitment Research Institute, after November 2017, the average recruitment salary for blockchain-related positions reached 25,800 yuan.

As the three giants of traditional high-paying industries, the Internet, finance, and professional services are firmly in the top three, with average monthly salaries more than 1,000 yuan higher than other industries. Specific to job requirements, there is a serious shortage of talents in high-tech positions, and they also have a crushing advantage in salary. In 2018, the average salary of talents in technology/R&D and product positions across the country reached 14,400 yuan and 13,900 yuan respectively, with an average salary increase of more than 5%.

『二』What do you think of “the global “new currency war” has just begun”

Yao Qian, director of the Science and Technology Supervision Bureau of the China Securities Regulatory Commission, said that with the rise of the modern information technology revolution, technology The impact on currency is reaching an unprecedented level, and Bitcoin has triggered large-scale digital currency experiments around the world. The digital age has arrived, and the digital currency era will surely come as well.

Recently, Yao Qian, director of the Technology Supervision Bureau of the China Securities Regulatory Commission, wrote an article in "Comparison" magazine, explaining the development of central bank digital currency and the theoretical logic behind it.

Yao Qian reviewed the changes in currency forms in his article. Due to technological advancement, currency forms have evolved from commodity currency, metal currency, banknotes to electronic currency, and now have extended to credit currency and high liquidity. financial assets and other broader monetary levels.

With the rapid development of digital technologies such as blockchain, big data, cloud computing and artificial intelligence, the impact of technology on the evolution of currency has further deepened.

Yao Qian said in the article that in addition to the transaction transfer function, currency often moves based on value. Wherever the value is more stable and the income is higher, currency will flow. And this kind of flow leads to currency substitution. This kind of currency substitution can lead to all kinds of tragedies and comedies in the world on a small scale. On a large scale, it can trigger "wars" to seize currency dominance, such as beggar-thy-neighbor exchange rate wars, various trade/currency alliances, reforms and games of the international monetary system, etc.

In the past, currency substitution was due to changes in the value connotation of currency, which can be called "classical currency wars." However, the current currency substitution caused by technology can be called "new currency wars."

There is also a "new currency war" that is the challenge of electronic payments to cash. In recent years, the use of non-cash payment methods such as Alipay and WeChat Pay has continued to surge. Terms such as "cashless society" and "cashless city" have appeared frequently in the media, and have even become the focus of some third-party payment institutions.Slogans to promote your business. Closely related to this is the decline in the proportion of central bank money in the overall monetary aggregates in many developed and emerging market countries. Since 2003, the ratio of base money to M2 has fallen by 5% in my country, 7% in India, and 3% in the Eurozone. Part of the reason is that central bank money (especially cash) is being replaced in circulation by more technologically advanced electronic payment methods and even private money.

For fiat currencies, the slogan of “decashification” of private payment instruments and the rise of “decentralized” digital currencies is more like a Morning Call to wake up the central bank. We should pay attention to the stability of the value of legal currency, awaken the central bank not to ignore the unavoidable technological wave of digital cryptocurrency, and awaken the central bank to pay attention to the integration and innovation of central bank currency and digital technology...

Yao Qian believes that this The "new currency war" can be traced back to the 2008 global financial crisis. The outbreak of the financial crisis has widely questioned the reputation of the central bank and the credit intermediary function of the entire financial system. The Austrian school of thought has made a comeback, and the number of supporters of currency "denationalization" continues to increase. In this context, decentralized programmable currencies represented by Bitcoin that do not rely on the credit of sovereign countries as value support "emerged". Some people even call it digital gold, pinning their dreams on replacing legal currency. This is the "war" between private currency and legal currency brought about by the development of information technology. It is the challenge of the "denationalization" of currency to legal currency.

The Libra white paper states: "Libra's mission is to build a simple, borderless currency and financial infrastructure that serves billions of people." Looking at it now, its grand mission may not necessarily succeed, but We should actively respond to such a vision, at least in terms of technology or model, it provides us with new references and options, which is beneficial to the progress of society.

Bitcoin sparked massive digital currency experiments around the world.

As early as 2014, the People's Bank of China officially launched research on legal digital currency to demonstrate its feasibility; in 2015, it continued to strengthen its efforts to carry out research on nine major topics; in 2016, it established the People's Bank of China Digital Currency Research Place.

After 2016, central banks in various countries also began to take action to carry out central bank cryptocurrency experiments based on blockchain technology, such as Canada’s Jasper project, Singapore’s Ubin project, the European Central Bank and the Bank of Japan’s Stella projects, the Inthanon project in Thailand, and the LionRock project in Hong Kong, my country.

This is a brand new track. Participants include the private sector, the public sector, sovereign states, international organizations, financial institutions, technology companies, industry alliances, geeks, and The Economist... Overall, this "new currency war" isjust started. There are many areas that need to be studied and discussed, such as disputes over technology routes, digital privacy protection, government supervision, social governance, network and information security, monetary sovereignty, financial infrastructure innovation, risk prevention, etc.

Unlike private digital currencies such as Bitcoin, legal digital currencies or central bank digital currencies are “established and prosperous” and do not have price instability and compliance issues.

Some economies have chosen the cryptocurrency technology route represented by blockchain technology, such as Canada’s Jasper project, Singapore’s Ubin project, the European Central Bank and the Bank of Japan’s Stella project, and Hong Kong’s LionRock project, Thailand’s Inthanon project, while some economies are wavering and are still controversial about whether to adopt blockchain technology.

Blockchain technology has the advantages of being difficult to tamper, traceable, traceable, safe and trustworthy, heterogeneous and multi-active, and intelligent execution. It is the prototype of a new generation of information infrastructure and a new value exchange technology. , distributed collaborative production mechanism and the basis of a new algorithmic economic model. Currently, central bank digital currency experiments based on blockchain technology in various countries are progressing rapidly, covering a wide range of topics such as privacy protection, data security, transaction performance, identity authentication, debt versus payment, and payment redemption.

Yao Qian believes that as a brand-new technology, blockchain certainly has shortcomings and shortcomings, but this shows that the technology has huge room for improvement and development.

Yao Qian finally said that although various countries have "triggered but not launched" and no real central bank digital currency has emerged yet, both the digital dollar plan and the digital dollar plan white paper indicate that the United States has officially joined " The Fierce Central Bank Digital Currency War”.

The international financial market has changed. The traditional financial center is the bank. In the future, the digital financial center will be the blockchain or blockchain network platform. The International Monetary Fund believes that this is an unprecedented historic event that changes It covers financial market structure, foreign exchange management, world reserve currency, regulatory system, and financial stability.

In February 2021, Tesla’s Musk disclosed the reason why he bought a large amount of Bitcoin because he was preparing for the U.S. dollar to There was negative interest, and in response to the resulting devaluation of assets, he found Bitcoin. We can track this reasoning process:

The new coronavirus has triggered an economic crisis in the United States;

The Federal Reserve prints a lot of money, the dollar depreciates, interest rates fall, and may even drop to negative interest rates;

Other assets followed suit, such as US stocks soaring;

Musk had a large amount of U.S. dollars. Due to the depreciation of the U.S. dollar, he looked for valuable asset investments and found Bitcoin;

But Bitcoin is a liquid asset. After its value has surged, its liquidity has exceeded the liquidity of legal currencies in most countries in the world;

The dollar is beginning to be threatened.

The phenomenon of digital tokens replacing the US dollar is a new phenomenon. In the past, this phenomenon would only occur in places where the domestic legal currency was not sufficient, but this time it happened when the domestic legal currency was the world’s reserve currency! If digital tokens can challenge the U.S. dollar, other legal currencies will also be challenged.

In February 2021, the title "US Government vs. Bitcoin" appeared in many American media. This means that Bitcoin has affected the US dollar this time.

You may not believe it after reading this. This incident will definitely shock the world, the confidence of the United States to go crazy, the real challenges faced by China, and the common sense of countless people Unimaginable danger. In particular, the continued spread of the epidemic has made people deeply aware of the true cruelty of this world.

In the analysis of the IMF report in November 2020, it has been proposed that the new currency war is no longer the binary competition (fiat currency, stable currency) that the United States believes, but a three-dimensional competition (fiat currency, stable currency, digital token) meta-competition. At that time (November 2020), the phenomenon of digital tokens replacing the US dollar had not yet appeared, but now, in February 2021, this phenomenon has begun to appear.

In the history of the Three Kingdoms period, in addition to the war between the two countries (while the other side watched), there was also a history of the two countries jointly attacking a third country, such as Cao Wei and Soochow to attack the Shu Han; or the Shu Han and the The Soochow Alliance fought against Cao Wei (Battle of Chibi). If history is anything to go by, does it mean that in the future, fiat currencies can cooperate with stablecoins to fight against digital tokens? Because digital tokens are global "currencies" and affect every country in the world, this will not only affect the United States, but other countries as well. The digital currency in the United States is Facebook’s Diem coin, not Bitcoin.

If this is possible, how should it be laid out? The U.S. Treasury Department didn't take that into consideration, and the Fed probably didn't take that into consideration either. I’ll leave it to the readers to think for themselves.

『三』Is there a war to grab people in the blockchain?

Blockchain has become a hot trend. Although focusing only on the trend will often lead to the loss of a forest, any change in the trend will give rise to new dividends. At this time, the word "change" spread rapidly: investment institutions, hedge funds, listed companies, academia, top technical personnel, and ordinary job seekers were all involved. A large number of newly established investment institutions have poured into this vigorous investment feast, and competition for talents has become a key to the current layout of the blockchain. So, who loses and wins in this game?

Funds rush to enter: tens of millions of yuan in financing is no longer surprising

How fast does capital rush enter the blockchain market? ?

“The most popular programming languages ​​​​for blockchain development are C++ and Go, and talents who are proficient in cryptography and distributed computing also have innate advantages for blockchain development.” Ding Song said, “I have never learned blockchain I am a blockchain major, but I have studied and studied in this area for a long time.” Regarding the newly entered blockchain training institution, Ding Song revealed that the salary offered by the company is also very “special”: in addition to a small fixed salary, each The monthly floating bonus is 0.1 to 0.35 Bitcoin. When recruiting, "having speculated in coins" has become a bonus.

“Using Bitcoin as a salary, to put it bluntly, even the salary is full of uncertainty, just like this industry. I feel that I am still young and can take a gamble, but I don’t see much of the future. Clear." In Ding Song's view, the popularity of a new thing will naturally be mixed with irrational bubbles, but what can survive in the end must be something truly valuable. However, what is the chance of winning if you invest blindly?

『四』The collective surge in blockchain concept stocks is a pie or a trap

The IT industry has been constantly hyped concept! It’s actually not that magical! Of course, those who can swindle money in China are good comrades.

『五』A hundred schools of thought contend | Cai Dong: The "Truman Show" hidden under blockchain technology

About Discussions on the application of blockchain have now frequently appeared in the public eye. However, when the technology itself is mature enough, what will happen if one day blockchain is truly used in all aspects of life? Imagine that one day, human beings’ entire lives from birth will be recorded on the chain. Will the life on the chain be a beautiful credit society like "Peachland World" or will it be like the movie "The Truman Show" that records life without distinction between right and wrong, making people want to escape?

In this issue of People's Digital FINTECH Hundreds of Controversies column, Mr. Cai Dong, Chief Information Officer of McDonald's (China) Co., Ltd., was invited to talk about whether we will inevitably become a movie from the perspective of blockchain technology maturity and application. Like Truman in the movie, he lives in the anxiety of being "surveilled" by the whole world all the time.

The 1998 movie "The Truman Show" tells the story of an ordinary little man who, without knowing it, The story of a man who was made into a famous TV star, but was completely deprived of his freedom, privacy and even dignity while the whole world watched him every moment, and became a victim of the mass entertainment industry. In the era of digital economy, Truman’s world is hidden in the technical characteristics of blockchain: decentralization (many viewers), openness and transparency (truth is revealed), and non-tampering (cannot be hidden), which sometimes reveals disturbing features. appearance. In the process of application, will such technology have a huge and irreversible impact on social concepts and personal life? Are we inevitably going to be Truman?

Blockchain technology is considered to be the next generation of disruptive core technology after steam engines, electricity, and the Internet. Since blockchain technology has the characteristics of decentralization, openness and transparency, and full traceability, it can be used to build an encrypted database that is shared by multiple parties, active in multiple places, cannot be tampered with, and has strict timing. Many people in the industry are optimistic about its development and believe that it will It is an upgrade and supplement to existing Internet technology and is expected to become the cornerstone of the digital economy era. However, from the perspective of practical progress, the difficulty of blockchain technology in the implementation process and its impact on current concepts, regulations and social systems have gradually revealed the hidden problems behind it.

I have returned to China since the end of 2015 and have carried out a very grand practice of digital transformation of physical business in Wanda Group, and I have a lot of emotions. First of all, we believe that blockchain technology itself is not yet mature, so we have participated in various standardization organizations and important international open source projects, and have conducted a lot of basic ecological cultivation and open source research and development work. For example, in 2016 and 2018, under the leadership of the Ministry of Industry and Information Technology, we compiled a blockchain white paper on the development of the blockchain technology industry with other leading enterprises, which can provide a relatively complete guide for enterprises on how to adopt blockchain technology according to local conditions, and help government agencies to judge and formulate regional Blockchain empowerment preferential policies.

From a technical level, although blockchain has the technical ability to record data and cannot be tampered with, copied or deleted, when applied to real life scenarios, A key problem must be solved: How to turn "atoms" in real-life scenarios into "bits" and then put them on the chain? If the authenticity of the data itself is doubtful, or even maliciously falsified by data observers, not only is it meaningless to put it on the blockchain, but its non-deletable nature will also produce meaningless occupation and even negative effects. For now, there is no universal standard for mapping the physical world and the digital world. Although physical businesses have long begun to use IoT technology to digitize the physical world and have achieved many benefits of digital transformation, there is also a lot of IoT data. example on the chain, but this is not enough. Blockchain technology, whether it is the premise of uploading the data itself or the hash value, is the core technical bottleneck of data completeness and system massive processing performance, which has led to no large-scale application so far.

From a social perspective, the decentralization, self-management, and collective maintenance characteristics of blockchain technology are bound to subvert people’s production and lifestyle and dilute the concepts of state and supervision. , impacting current legal arrangements. For these, the entire world completely lacks theoretical preparation and institutional discussion. Even for Bitcoin, the most mature blockchain application, different countries have different attitudes, which inevitably hinders the application and development of blockchain technology. For another example, the openness and transparency brought by blockchain technology can prevent some middlemen from making profit in the entertainment market and bring benefits to consumers of cultural products. It can also make copyright information open and transparent and stimulate the entire entertainment industry.The industry is actively creating and producing high-quality content, but users’ habit of listening to music on centralized platforms is difficult to change in a short period of time. Vested interests in these fields will also be “taken away from the cake”, such as the traditional ticketing market. Will be challenged, and may also incur strong backlash from large companies.

In addition, the threats to personal privacy data that may be brought about by blockchain technology during its application are also worrying. As the digital economy develops in full swing and data is increasingly recognized as a factor of economic production, user data ownership has been repeatedly violated and privacy leaked. Giant Internet companies have gradually become data oligarchs, leading to global conflicts over data ownership and privacy protection. Intensifying. The reasonable use of user access, consumption and other behavioral data and user privacy data is an important challenge for modern civilization. It is not only a technical challenge, but also an ethical and compliance challenge. For example, if blockchain technology is applied to the field of biological big data and users' genetic sequencing data are uploaded to the chain, how can the sequencing data of many users be reasonably and legally used in the field of scientific research to reveal the mechanisms of diseases? To benefit future generations of mankind, how to prevent users’ genetic disease and cancer risk information from being leaked by others, which would have a fatal impact on the user’s personal emotional life and social evaluation? The implementation of blockchain technology in the future will inevitably involve choices about the fields it enters, as well as weighing moral and ethical issues.

We can foresee that in the future, more and more things and behaviors will be digitized through data on-chain, and then Be capitalized, but the original ownership of the data is always with the data owner, who is the owner of the data. While enjoying the online value-added circulation of the digital economy, it can also bring people more diverse economic activities in the real economy. But think about this kind of life, do you want to escape?

The theme of the next issue is "The World War of Digital Currency"

Viewpoint 1: Will digital currency rebuild the future monetary system?

Opinion 2: "Suppress the bandits" before the war, the encirclement and suppression of the currency circle is imminent

Who will be invited to debate in the next issue? Stay tuned! Readers are welcome to actively contribute articles to participate in the discussion.

『Lu』 The first blockchain scoring trophy appears in this European Cup. Who has the best chance to win it?

France, the favorite of this European Cup so far, has been eliminated. , the defending champion Portugal was also eliminated, and the German team also lost to England. At present, Italy and England are expected to win the championship, but there may be a dark horse team. After all, in the history of the European Cup, this kind ofThis situation often happens, but after France was eliminated, Italy and England are the most popular teams. These two teams have the hope of reaching the top of Europe.

The final should be England versus Italy. England is more optimistic about winning the championship.
