① What is the relationship between blockchain and digital renminbi

Digital renminbi is often compared to cryptocurrencies such as Bitcoin and Ethereum that use blockchain technology. Digital RMB draws on blockchain technology, but as a legal currency, digital RMB has centralized characteristics. Executives from major European central banks said that issuing central bank digital currencies does not actually require the use of blockchain technology. The core elements of the digital RMB system framework are "one currency, two databases, and three centers". The technologies used in the use process include NFC and distributed ledger technology.

Related listed companies in the digital renminbi industry: Radio and Television Express, Changliang Technology, Lakala, Digital Certification, etc.

The core data of this article: core elements of the digital renminbi system framework

1. The characteristics of blockchain are distributed and decentralized

Digital RMB is often compared to cryptocurrencies such as Bitcoin and Ethereum that use blockchain technology. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method that uses smart contracts composed of codes to program and operate data.

2. my country’s digital renminbi only borrows from blockchain technology

The digital renminbi has the same characteristics as blockchain technology, such as traceability and non-tamperability, but the digital renminbi only borrows from of blockchain technology. As a legal currency, one of the main features of digital renminbi is a centralized management model, while one of the core features of blockchain is decentralization.

Previously, countries that have issued digital currencies based on blockchain technology include Iran, Ecuador, Uruguay, Senegal, etc., but these digital currencies have not become popular. In September 2020, executives of major European central banks stated that if central banks around the world want to issue central bank digital currencies, they do not actually need to use blockchain technology. In the case of central bank digital currencies, central banks provide " Trust”, so there is no need to use blockchain technology when the central bank steps in.

In the financial field, blockchain technology is currently used experimentally or on a small scale in digital currency, payment and clearing, digital bills, bank credit management, etc.:


3 , The core elements of the digital RMB system framework are "one currency, two treasury, three centers"

According to the "Prototype Concept of China's Legal Digital Currency", the core elements of the digital RMB system framework are "one currency, two Library, Three Centers”. Among them, "one currency" refers to the central bank's digital currency; "two libraries" refers to the digital currency issuance library (the database where the central bank's digital currency issuance fund is stored) and the digital currency bank library (the database where commercial banks store the central bank's digital currency); "three libraries" "Center" refers to the certification center (responsible for identity information management), registration center (responsible for digital currencyOwnership registration) and big data distribution center (responsible for analysis of anti-money laundering, payment behavior, etc.).


4. Technology used in the use of digital renminbi

The use of digital renminbi involves multiple links such as currency issuance, storage, payment, and transaction recording.

In the digital RMB payment process, due to the use of NFC technology, in addition to mobile phones, the payment media for digital RMB also include "digital currency chip cards". The implementation of chip cards makes it easier for the elderly to use. "Digital currency chip card" specifically includes five forms: visual Bluetooth IC card, IC card, mobile phone eSE card, mobile phone SD card, and mobile phone SIM card. In addition to using NFC technology, some digital currency chip cards interact with smartphones through Bluetooth technology to achieve query and account information synchronization.

In the digital RMB transaction recording process, through distributed ledger technology, the central bank and commercial banks build a CBDC distributed rights confirmation ledger, provide a website for external inquiries about CBDC rights confirmation through the Internet, and experiment with online banknote verification. machine function.

② It is said that Qulian Technology has cooperated with People’s Daily Online

Yes, that’s right, People’s Daily Online’s “People’s Chain” is based on Qulian Technology’s blockchain technology. Lian Technology also co-authored the "People's Lian Technology White Paper" with People Online!

③ What is digital currency

Digital currency is the product of blockchain technology. When it comes to digital currency, it is inseparable from blockchain technology. Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness.
From a financial accounting perspective, blockchain can be seen as a highly credible network electronic ledger in which all nodes participate. Compared with WeChat, Alipay and other application systems, there is a large central database account book behind them; the blockchain implements network-wide collaborative accounting and verification, and all nodes participate in accounting. Each time accounting is done, a new block will be formed, namely Block; each block can only be packaged by one node. After solving a mathematical problem (hash algorithm Hash) to determine that the information is legal, it will be broadcast to the entire network, adding to the end of the previous block and recorded by other nodes. The ledger chain formed in chronological order is the blockchain. In order to motivate bookkeepers (that is, those who pack blocks), the system will give certain digital currency rewards, and this process is mining. Since the design and generation mechanism of digital currency determines that the quantity is limited, it forms the basis for the consensus that digital currency has value.
Digital currency is based on digital principles and is a network virtual currency generated through large-scale calculations through specific algorithms. The European Banking Authority defines virtual currency as: a digital representation of value that is not issued by a central bank or authority and is not linked to a legal tender, but which, because it is accepted by the public, can be used as a means of payment or can be transferred, stored or traded electronically. . This is the earliest concept of digital currency. With the development of technology, digitalThe concept of currency has also gradually been extended, and is not limited to the use of blockchain technology. In our country, digital currency in the official sense refers to the central bank's legal digital currency, that is, the digital currency issued by the central bank, which is a liability of the central bank, has national credit, and is equivalent to legal currency.
[Extended information]
1. The importance of China’s issuance of digital currency
The current economic society is a highly developed credit economy. It is difficult for non-statutory digital currencies with defects in currency issuance and management functions to take on major responsibilities. The core problem is that it is difficult for such transferable digital assets to build their own value support system. From the nature of currency, only the state can exercise the highest power to issue currency. For sovereign countries, the best way to practice the country's right to issue currency is for the government and the central bank to issue sovereign digital currencies within the control scope. The launch of digital currency by my country's central bank has important breakthrough significance.
To sum up, the central bank’s promotion of digital currency has four major significances:
1. Accelerate the internationalization of the RMB. The current mainstream cross-border clearing model in the world is through the SWIFT system led by the United States. In the future, the central bank's digital currency may flow out of the country, which can partially accelerate the internationalization of the RMB, replace the offshore RMB/IMF Special Drawing Rights, create the central bank's international digital credit assets, and become a means of cross-border settlement.
2. Influence monetary policy more efficiently. The pricing standards for currency are clearer, thereby greatly improving the accuracy, timeliness and effectiveness of currency prices. The emergence of legal digital currencies can provide new monetary policy tools to support central bank management.
3. Real-time centralized collection of currency flow data. The issuance of central bank legal digital currency will also make it possible to collect real-time data on currency creation, accounting, and flow.
4. Currency tracking helps with anti-money laundering and counter-terrorism.

④ People's Daily Online invited the general manager of Beijing Yumede to be a guest to discuss blockchain applications and cooperation

On July 15, 2022, Beijing Yumede Intellectual Property Service Co., Ltd. ( (hereinafter referred to as "Beijing Entertainment Virtue") General Manager Xu Tingxu and his party were invited by People's Daily to visit the New Media Building of People's Daily. People's Kaihui Fiber Network Lingjing·People's Art Museum CEO Yang Cheng also attended the exchange event and discussed relevant cooperation with Xu Tingxu Conducted in-depth discussions. Xu Tingxu also introduced the development plan of Yumeide and the development status of the "Legend" game.
(Xu Tingxu, general manager of Beijing Yumede, was invited to be a guest at People's Daily Online)
Xu Tingxu introduced the development history of Yumede. Yumede was established in 2000 and completed the development of the famous online game "Legend" in the same year. Since the introduction of Chinese Shiqiang in 2001, its popularity has not diminished. It has developed from a game to an IP, and Yumede has also developed into a multinational company, with its business covering game development, distribution, investment, blockchain, etc. .
Yumeide has also continued to develop some follow-up products of Legend. In 2020, "Legend 4" was launched in South Korea, triggering a craze; after the international version of "Legend 4" was launched last year, simultaneous online users around the worldThe highest number exceeded 1.5 million, which was almost three times the number of people online at the same time when "Legend of Blood" was the most popular in China. Xu Tingxu said that the main reason why the international version of "Legend 4" is so successful is that it is combined with blockchain technology. The international version of "Legend 4" has launched character NFTs and has also turned some major in-game assets into NFTs. Yumeide provides a special platform where NFT digital cards can be uploaded for the convenience of players.
The success of the international version of "Legend 4" has also allowed Yumede to accelerate the pace of improving its metaverse plan. Yumede has launched a new blockchain game platform Wemixplay, and hopes that it can become a global game company. The backbone of the service-based ecosystem for blockchain games. Yumeide recently added 9 games to the Wemixplay blockchain game platform, which allows developers to launch blockchain games without knowing much about Web3 and brings game developers and players closer through decentralization connected together. Yumeide hopes to have 100 games launched on Wemixplay by the end of 2022. In addition to focusing on the development and application of blockchain technology, Yumeide has also made 22 investments in blockchain projects around the world this year.
When talking about the field of blockchain, Yang Cheng not only introduced Lingjing·People's Art Museum, but also put forward suggestions for cooperation with Yumeide. Lingjing·People's Art Museum was officially launched by People's Daily Online in January this year, aiming to provide a digital platform for artists and outstanding works of art, and provide services for digital copyright protection of artworks, digital publishing, digital transformation, digital certification (blockchain), etc. , using digital technology to serve popular art. The digital collection issuance of Lingjing·People's Art Museum will focus on the fields of art, performance, film and television, and public welfare. It will also try to distribute digital collections related to Chinese culture overseas to open up a new path for Chinese culture to go global and explore Chinese culture. New forms of overseas communication have allowed China’s excellent traditional culture to become an important source of literary and artistic innovation with the help of new technological means.
(Lingjing·People's Art Museum is online)
"Legendary" is a familiar IP, whether it is story or character art, etc., there are many areas worthy of development, and "Legendary" IP is also closely related to Lingjing·People's Art The theme of the museum is highly consistent. In the future, Yumeide can authorize Lingjing·People's Art Museum, and then Lingjing·People's Art Museum will digitize the relevant results of the "Legendary" IP, and then develop related derivatives to enrich the platform's work library, and the development of such products At the same time, it can attract more people to pay attention to the story and scenes of the game, and even become new game players, forming a complete chain of mutual promotion. The two parties have also developed more ideas about possible in-depth cooperation, which is also worth looking forward to.
After years of development, China’s domestic game market has risen rapidly, and competition has become increasingly fierce. For Chinese game companies, it is urgent to go global. Over the years, Yumeide has always hoped to use its rich publishing experience to help the vast number of small and medium-sized games in China.Enterprises go overseas and support more game works to go global. As the company with the most successful blockchain games currently, more than 30 games have been launched on Wemixplay, the Yumeide blockchain game platform. Xu Tingxu hopes that in the future, games developed by Chinese companies will be launched through the Wemixplay platform, making it easier to Enter the global market and embark on a new development path.
Xu Tingxu said that for Yumede, the Chinese game market is the most important market. Yumede has also planned a number of measures to support Chinese game manufacturers, hoping to bring vitality to the majority of small and medium-sized enterprises and maximize the IP value of the game industry. , game operations and other aspects to create new ideas. In addition, Yumede also actively participates in projects that are beneficial to China's social and cultural development and grows together with Chinese companies. Yumede's goal is to become a cooperative body that can coexist and prosper with most Chinese game companies.
(Xu Tingxu, general manager of Beijing Yumeide, visited the development history of People's Daily)
The "Legend" game has achieved great success in China, with many users and a huge volume. The huge profits brought by the Legend game market have also led to piracy There are endless infringement phenomena. As a game development company, Yumede has always attached great importance to the protection of intellectual property rights. Yumede has adopted a multi-pronged approach through prosecution, complaints and reports, and jointly with local governments, and has achieved good results in safeguarding rights. So far, Yumede has won more than 20 cases, and more than 3,000 legendary infringing games have been removed from the shelves.
Xu Tingxu introduced that after obtaining the authorization to maintain the intellectual property rights of the "Legend of Legend" work within mainland China, Beijing Yumeide actively carried out rights protection activities and cooperated with the public security organs and relevant departments to fight against infringements involving the "Legend" game. The behavior was severely punished. From now on, all business related to the "Legend" IP, including rights confirmation and authorization, will be completed by Beijing Yumeide.
The success and value of "Legendary" IP are a reflection of Yumede's R&D strength. Yumede's exploration and practice in the field of blockchain also present more possibilities for the development of games and other industries. I believe People.com We can establish in-depth cooperation with Yumede based on the "Legendary" IP, develop more forms of excellent works, and explore and create new development directions in the cultural field.

⑤ How do we create a good cyberspace order

1. The first thing is to strengthen positive publicity online and adhere to the correct political direction, public opinion orientation, and value orientation. "In the midst of hemp, one can stand straight without support; in the midst of white sand, it becomes black." The powerful communication power of the Internet can easily "illuminate" vulgar culture, extreme emotions, and distorted judgments from the virtual into reality, thereby affecting people's thoughts. Concepts, value pursuits and words and deeds. Without guidance in the right direction, it will be difficult for cyberspace to become truly clear.

The Internet is neither an "enclave" of public opinion nor a private "racecourse." We should not only let the main theme and positive energy dominate the pages of newspapers and periodicals, radio stations, and TV screens, but also let them dominate communication carriers such as online space and mobile platforms. We cannot have two standards.accurate, forming "two public opinion fields." Only with abundant positive energy and high-pitched main themes can we build a spiritual home that makes hundreds of millions of people feel at ease and at ease.

2. If you don’t stir up the turbidity and raise the clearness, you can’t look at things correctly. A positive, healthy, and kind-hearted online space can nourish people's hearts and nourish society. A smoky and noisy public opinion atmosphere will only confuse the public and intensify conflicts. No one likes to "surf" in turbid sewage, and no one can "hunt for treasure" in junk information.

To create a clean and upright online space, we must not only maintain political stability and not be led by some online comments, but also quickly make judgments on online public opinions, speak out when it is time to speak up, and promote integrity. , refute fallacies, resolutely resist rumors and criticism, and erroneous ideological trends "racing for territory" online, and continue to consolidate and strengthen mainstream ideological and public opinion online. Only in this way can we seek consensus among diversity, neutrality, and diversity, maximize our efforts, and become a good person.

3. Advocating a good network ecology does not mean that there can only be one voice or one tone. General Secretary Xi Jinping pointed out, “We must not only welcome well-intentioned criticism on the Internet and Internet supervision, whether it is directed at the work of the party and government or at individual leading cadres, whether it is gentle and gentle or has harsh words. We must study and learn from it carefully.”

Leading cadres at all levels must be more tolerant and patient with the Internet, be good at following the mass line through the Internet, and make the Internet a new platform for communication with the masses and a way to solve problems for the masses. New ways, new channels to accept people’s supervision. However, there are no exceptions to the rule of law. The Internet must also operate on the track of the rule of law. It cannot become a platform for deliberate rumors and illegal crimes, and it cannot allow online behavior to exceed the boundaries of the constitution and law.

(5) Extended reading on People’s Daily Online’s blockchain technology:

Necessary points for jointly building a trustworthy cyberspace:

< p>First, it is necessary to build a reliable technical foundation. The Romans had a saying about trustworthiness: "He whom you can trust in the dark." Building a virtual cyberspace requires such trust. Therefore, all areas of the Internet should develop and apply network technology from the perspective of "trustworthiness".

Through unremitting efforts in all aspects, artificial intelligence will become a powerful tool for fact-checking news, blockchain technology will build a safe and reliable trust system, and quantum communication technology will protect autonomous network communication.

Second, it is necessary to build a credible market environment. Judging from the development process of the Internet, user choice is the basis for trust generation, and the market is the source of trust and the soil that most needs trust. The in-depth implementation of the "Internet +" strategy will further expand and strengthen my country's digital economy and network economy.

To this end, on the one hand, we must adhere to market rules and the spirit of contract, and build a credit system suitable for the Internet; on the other hand, we must vigorously advocate interpersonal integrity and social civilization to allow more mutual trust in market operations.

Third, it is necessary to provide credible legal protection. According to laws and regulations, Internet communication should be, applications and platforms and other participating entities. The development of the Internet is constantly giving rise to new business forms, but it should not leave a legal "blank" nor become a management "enclave."

While improving laws and regulations, we must also pay more attention to collaborative social governance. Management departments should fulfill their regulatory responsibilities, Internet companies, including online media, should assume main responsibilities, and Internet users should fulfill their civic obligations. Through joint efforts from all parties, we will be able to build a healthy, orderly, well-intentioned and trustworthy cyberspace.

⑥ How does blockchain protect media content

Due to the large amount of media content produced every day, traditional copyright protection can no longer meet the needs of media intellectual property protection due to high costs and cumbersome processes. , in order to better protect media content, some media began to explore the introduction of emerging technologies to protect intellectual property rights.
Since blockchain was incorporated into new infrastructure, it has become widely known to the public and is used by the media to encrypt content and record evidence, providing professional and reliable ownership certificates and infringement evidence for media rights protection. .
Currently, some media are beginning to try to establish their own blockchain intellectual property protection platforms. For example, People's Daily Online has created the "People's Copyright" platform, and Cover Media has created the "Cover Blockchain Digital Content Copyright Certification System".
However, due to the pressure of funds and technology, there are still only a few domestic media that have built their own blockchain intellectual property protection platforms. Most media choose to directly cooperate with third-party blockchain institutions to effectively protect their rights through prior prevention and ex-post rights protection. Improve the efficiency of intellectual property protection.

⑦ Development of new media

With the continuous advancement of artificial intelligence, VR, AR and other technologies, the new media field has shown unprecedented changes. In the face of iterative changes, we must clearly understand and grasp the changing trends and development characteristics of new media, so that we can fully utilize new technologies and new applications to innovate communication methods, and truly achieve the goal of occupying the commanding heights of information dissemination. In the past two years, we have experienced a leap from the "multimedia era" with universal participation to the "intelligent media era" with human-computer interaction. The entire process of news production and user behavior have undergone disruptive changes. This article relies on the latest survey data on the use of new media by netizens in the United States and China from the Pew Research Center, Penguin Intelligence and other survey agencies, and proposes the future development direction of new media from five aspects: form, content, users, technology and services. Some thoughts. It is hoped that this partial observation of the development trajectory of new media will serve as a reminder for the in-depth study of related research and the expansion of related industries. Form: From video to live broadcast, the leading role of government live broadcast needs to be strengthened. The rise of online video services has greatly changed the media consumption habits of people, especially young people. According to data from the Pew Research Center in August 2017, 61% of young Americans (19 to 28 years old) said that they mainly watch TV programs through online services. This impact on television media is obvious. Already 24% of Americans no longer subscribe to cable television services①. Our country’s data is even more striking: Netizens’ response to the richMedia preference is rising rapidly. The number of netizens obtaining information through video websites increased by 228% in 2017. The penetration rate of China’s information video consumption reached 61.8%, which is approximately twice that of the United States②. The content of online video services has also achieved iterative development, from early online viewing of TV programs, to original video release, to the current popular online live broadcast. This bottom-up interactive social method has helped ordinary people realize the discourse greater liberation of rights. However, the shortcomings of live video broadcasts were quickly exposed. Really valuable live content such as on-site records of emergencies and informative live broadcasts only account for a minority. Most live broadcast platforms focus on life-oriented and entertainment-oriented content, and daily life is limited. Live broadcasts inevitably tend to be homogenized, vulgar, vulgar, and demonized. Against this background, the government has significantly increased the management of live broadcast platforms and video releases to reasonably guide live broadcast platforms to play a positive role in social construction. In addition, improving and strengthening the social functions of government live broadcasts and highlighting its leading role in online live broadcasts are also key tasks that need to be promoted. At present, government live broadcast shows a good momentum of rapid development and multi-sector coverage. However, there are still some gaps between systemization, normalization and branding. To do this, the content issue must be resolved first. Currently, the live broadcast of government affairs in most departments is mainly used for reporting on major events. In the future, government affairs live broadcasts should be extended more to social, people's livelihood, economic and other fields that people care about. Especially when facing controversial social issues, they should not shirk or avoid taboos, actively set live broadcast agendas, and guide public opinion. At the same time, we must grasp the scale and make good choices in live broadcast content to promote the normalization of government live broadcasts. Secondly, we must improve the platform construction issues. Currently, government affairs live broadcasts are mainly realized through third-party live broadcast platforms, which are inevitably mixed with other relaxed and entertainment live broadcasts, making them appear scattered, chaotic and unsystematic. Therefore, we must strive to create an independent and specialized government live broadcast platform, classify live broadcast themes, and bring together government departments at different regions and levels to form a government live broadcast matrix. Finally, we need to solve the problem of influence. The difference between government live broadcasts and general live broadcasts is that they usually involve serious or even boring topics, making it difficult to mobilize the enthusiasm of users. This requires all departments to give full play to their live broadcast skills, learn to combine serious issues with relaxed expressions, replace official accents with sincere interactions, and improve the live broadcast situation to not only make it easier for the audience to accept, but also more willing to accept it. This is also an important part of improving the government's ability to guide public opinion in the new era.

⑧ Refute the People’s Daily Online’s discussion on cryptocurrency

Recently, taking advantage of the sharp decline of Bitcoin, two well-known experts published on the People’s Daily Online that “Virtual Currency Is After All a Dream” The article "Ponzi Scheme" declares that "Cryptocurrency" is "undoubtedly the largest Ponzi scheme in human history."

From a translation perspective, the word "Cryptocurrency" should be translated as "cryptocurrency" ” or “numberCurrency", thereby distinguishing it from the so-called "virtual currency" label. In terms of scale, with Bitcoin falling to $20,000, the current total global cryptocurrency market value is around $1 trillion, while the total market value was once Breaking through 3 trillion US dollars, its skyrocketing and plummeting nature does involve great investment risks.

However, when we look back to 2012, 10 years ago, Bitcoin at that time was approximately 14 yuan a piece, compared with today's approximately 140,000 yuan a piece, has increased 10,000 times in 10 years. No wonder some people would jokingly say: Ten years ago, why didn't I "be deceived" and "don't let me" Huang Liang Yi Meng"!

The two authors pointed out in the article: "Among the top 100 richest people in the world, at least 90 have publicly stated their negative attitude towards virtual currencies, including Bill Gates, Buffett, Munger, etc.” The author really doesn’t know where the basis for the statement “90 of the world’s top 100 richest people are badmouthing Bitcoin” comes from. If so many rich people really come out to “badmouth” it, it can only mean that encryption The influence of currency has been astonishing.

As for Bill Gates, Buffett, Munger, etc., they are indeed the world's most famous investment "big guys". They are also the current global investors centered on the United States and the US dollar. Among the core representatives of the financial and wealth system, Buffett is 92 years old this year and Munger is 98 years old. Even in the United States, there is a large wave of young rich people who are fans of cryptocurrency: Musk, the world’s richest man, is a famous cryptocurrency “shouker”. "Single Man", Marc Andreessen, known as the "Silicon Valley Prophet", believes that artificial intelligence, biotechnology, cryptocurrency and Web3 are the three most promising technology fields in the future.

"A Dream in Huangliang" The author of this article denounces Bitcoin and other cryptocurrencies as "Ponzi schemes." It is undeniable that in today's cryptocurrency market, various "air coins" with the nature of pyramid schemes and capital disks are indeed emerging in endlessly, but Therefore, "beating cryptocurrencies to death with a stick" is too arbitrary in the author's opinion.

Overall, we can classify the current digital currencies (cryptocurrencies) as follows:

(1) Sovereign credit digital currency

Representative currency: Digital RMB (ECNY)

Characteristics: Sovereign credit digital currency can also be called digital legal currency. Its essence is The digitization and encryption of legal currency have the same legal status as legal currency and are endorsed by government credit. The foundation of sovereign currency is based on national credit, and its credit foundation comes from stable countries and responsible governments.

We have seen that in recent years, the Chinese government and Chinese system have performed outstandingly in assuming social management responsibilities and developing the economy. Therefore, China's sovereign credit currency, the RMB, should and can play a more important role in the world. . As the world’s first digital sovereign currency using encryption technology, the digital renminbi (ECNY)Leveraging technological leadership and the good credit of the RMB, it is expected that many countries and regions around the world that have not yet enjoyed modern financial conveniences will leap into the digital financial era. The encryption and digitization of RMB will also become an important weapon for my country to participate in global financial competition and reform.

(2) Asset-type digital currency

Representative currency: Bitcoin (BTC)

Characteristics: Based on computer science and cryptographic mathematics, The computing power certificates are condensed in the form of power and cannot be tampered with. These certificates generate value due to people's consensus and thus have asset attributes. The value formation process of these digital assets can be compared to the value formation process of gold, silver, gemstones and other valuables.

People usually regard Bitcoin as "digital gold": looking back at human history, shells, animal feathers, stones, etc. have all been used as value anchors. Gold, jewelry and other valuables, regardless of their limited use value, are essentially just stones in nature; the value mission of gold and silver is only a historical stage. As we live in the intelligent era and the early stage of the computing era, we should look at the changes in value from a historical perspective - Bitcoin, which represents the beauty of computing, algorithms, and computing power, is expected to become the value anchor of the intelligent era due to its originality. .

(3) "Fuel" digital currencies

Representative currencies: Ethereum (ETH), Treecoin (CFX)

Features: " In the "digital industrial system", the digital currency that acts as "fuel" to provide power for the operation of smart contracts in the system can be compared to the "coal" and "oil" in the traditional industrial system. This type of digital currency usually has greater actual use value.

(4) Equity digital currency

Representative currencies: Binance Coin (BNB), Warless Coin (EB)

Characteristics: Such numbers The essence of currency is digital equity or equity. Usually the issuer of this type of digital currency will promise to empower these digital currencies through dividends, destruction of tokens, participation in governance, use in games, etc.

From a regulatory point of view, these types of digital currencies should be supervised by the securities regulatory authorities with reference to the form of stocks. Strict supervision should be carried out in terms of information disclosure, fund raising and use, and the issuance of " Behaviors such as "air currency" and "traveling money and running away" will be cracked down in accordance with the law. The issuance of shares in the form of digital equity is expected to become an important supplement to the capital market.

(5) Illegal and criminal activities in the name of digital currency

Representative currencies: Plustoken, MMM

Characteristics: Using digital currency as a carrier, organize and develop personnel , by promising high returns, to the people being developed based on the number of people they directly or indirectly develop orIt is an illegal act to obtain wealth by calculating and paying remuneration based on performance, or requiring employees to be developed to obtain membership qualifications on the condition of paying a certain fee.

From the above classification, we can see that a "Ponzi scheme" is a "Ponzi scheme" and cryptocurrency is a cryptocurrency. It cannot be because there are a large number of "Ponzi schemes" using cryptocurrency as a carrier. A total denial of cryptocurrency itself.

In view of the huge risks of cryptocurrency investment and the rampant illegal financial activities using cryptocurrency as a carrier, my country has issued a series of normative documents: For example, in 2013, the central bank and other departments issued warnings The risks of speculating on virtual currencies; in 2017, the "94 Notice" strictly prohibited virtual currency ICOs and the opening of exchanges; in 2021, "mining" and speculative transactions of various virtual currencies were strictly prohibited.

From the perspective of maintaining national financial security, the introduction of this series of policies is very necessary and has played an important and positive role in curbing related financial violations. However, the country currently does not explicitly prohibit individuals from holding cryptocurrency, nor is it illegal for individuals to conduct private transactions.

In fact, in the face of a new product in the information age and the intelligent age such as cryptocurrency, a new thing that may bring about "big changes not seen in a thousand years", we must not only guard against risks, It is also necessary to observe carefully, and even learn from its strengths, and should not "determine his life or death with one word."

The author of "Huang Liang Yimeng" finally pointed out: "The original huge value of blockchain technology should not be ignored because of virtual currency. From a technical perspective, blockchain is essentially an application The broadcast data transmission method achieves consensus on data structure, traceability, authority and verification, forming a distributed and open and transparent information system, while virtual currency is just a simple application based on blockchain."

We have also seen a rather peculiar phenomenon in China. The concept of blockchain was once in full swing. Many local governments and state-owned enterprises also invested a lot of money, and "blockchain industrial parks" continued to emerge. . However, at the level of ordinary people, so far they have not felt that blockchain has brought any changes to their lives. Even many platforms that claim to be built with "blockchain technology" are all traditional network technologies upon closer inspection. "Fooling" the government and "fooling" state-owned enterprises have become important "business models" for some so-called blockchain companies.

As ordinary people, since the country currently does not advocate investing in cryptocurrency, we will respond to the country’s call. But we hope that our country’s experts and scholars will spend more time researching and promoting how to make blockchain technology make our lives better, instead of arbitrarily denying a certain application of blockchain technology, even if it is just a " Simple application".

⑨ What is blockchain technology? What exactly is blockchain?

Narrow senseGenerally speaking, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security andPersonal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.
