⑴ What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don't need to careUnderstand the mechanisms behind this technology, but you need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

⑵ An article to understand what the Metaverse is

What exactly is the Metaverse Network?

What is the Metaverse?

The metaverse began with the two concepts of "Metaverse" and "Avatar" mentioned in the foreign science fiction work "Avalanche" in 1992. People can have their own virtual avatars in the "Metaverse", and this virtual world is called the "Metaverse".

Shen Yang, executive director of the New Media Research Center of Tsinghua University, said that the Metaverse is a new Internet application and social form that integrates virtual and real technologies and is created by integrating multiple new technologies. It provides an immersive experience based on extended reality technology. And digital twin technology generates a mirror of the real world, builds an economic system through blockchain technology, closely integrates the virtual world and the real world in the economic system, social system, and identity system, and allows each user to produce and edit content.

The Metaverse itself is not a technology, but an idea and concept. It needs to integrate different new technologies, such as 5G, 6G, artificial intelligence, big data, etc., emphasizing the integration of virtual and real.

The Metaverse mainly has the following three core technologies

First, it is extended reality technology, including VR and AR. Extended reality technology can provide an immersive experience and solve problems that mobile phones cannot solve.

Second, it is a digital twin, which can mirror the real world into the virtual world. This also means that in the metaverse, we can see many virtual clones of ourselves.

Third, use blockchain to build an economic system. With the further development of the metaverse, the degree of simulation of the entire real society has been strengthened. In the metaverse, weIt may not only be spending money, but also making money, which also forms an economic system in the virtual world.

Why should we pay attention to the Metaverse?

Every technological iteration and innovation will mean a new opportunity, a new challenge, and a new beginning. The industry has implemented a series of actions in the face of the Metaverse, including Facebook announcing that it has changed its name to "Meta", which comes from the "Metaverse". The decision of such a large Internet company to change its name shows from the side that the metaverse is really approaching, and the era of isomorphism between the real society and the virtual world is coming.

At present, the main bottleneck in the development of the Internet is the involution of the platform form. There is a long-term lack of breakthroughs in content carriers, communication methods, interaction methods, participation and interactivity, etc., resulting in "growth without development" . Technology is eager for new products, capital is looking for new outlets, and users are looking forward to new experiences. Some experts have pointed out that the Metaverse is like an embodied Internet. In the Metaverse, you do not simply browse the content, but are immersed in the content. among.

From Internet 1.0, 2.0 to mobile Internet, Metaverse may be the next new Internet era to succeed Sun Chan’s mobile Internet. Due to its application in the gaming field, some people believe that the Metaverse is equivalent to video games and virtual worlds. Some experts have expressed different views on this. The Metaverse cannot simply be equated with video games, nor can it be equated with the virtual world. It is about creative play, open exploration, and connection to reality.

In recent years, the Internet has relied on a series of leading artificial intelligence technology capabilities including intelligent vision, intelligent speech, natural language processing, knowledge graphs, etc., and has launched virtual reality content platforms and virtual reality interactive platforms with the help of the Internet. Platform, the production cost of content in the Metaverse world will be greatly reduced, and it will promote the upgrade of hardware consumption experience and the improvement of content production efficiency. "The Metaverse will become humanity's second space parallel to the real world."

Ma Jie, vice president of the network, believes that the Metaverse is essentially a process of virtualization and digitization of the real world, which requires a deep understanding of content production and The economic system, user experience, and physical world content have undergone extensive transformations. However, the development of the Metaverse is gradual. It is finally formed by the continuous integration and evolution of many tools and platforms under the support of shared infrastructure, standards and protocols.

What aspects of the Metaverse deserve attention?

For the concept of the metaverse to come true, it involves not only pictures, but also solving the needs of multi-person interaction. Different from traditional online games and online meetings, the high real-time, high interactivity and high immersion of the Metaverse require that the virtual space needs to be able to accommodate tens of thousands or even hundreds of millions of users for simultaneous communication.

In the development process of the Metaverse, we will also encounter new issues such as value ethics and virtual space control, which require further regulation by regulatory authorities. When real space meets virtual space, in addition to paying attention to technological developmentThe changes brought about require more attention to the meaning of ‘value’ itself, and orderly policy supervision must be included to ensure the healthy and orderly development of the industry.

At this stage, the metaverse is still an evolving and developing concept, and different participants will continue to enrich its meaning. We need to be alert to issues such as capital kidnapping, ethical risks, and gaps in legislative supervision. Some companies are taking advantage of the popularity of the Metaverse and starting to make money, while others are putting everything into the Metaverse. These phenomena deserve attention. Bubbles and negative issues that arise in the metaverse need to be managed accurately.

The metaverse is a future, a future that will be realized to a large extent, and now is the best time to take the initiative. To realize it in the shortest possible time requires the organic cooperation of the entire society. Whether it is technology companies, content companies or capital, they all need to start from the underlying technology and find a breakthrough in the content ecosystem.

⑶ How to realize the concept of blockchain technology

There are many ways to realize the concept of blockchain. For example, blockchain can create a better user control mechanism. User information today can easily be manipulated, distributed to third parties, and even sold, creating revenue streams for social media platform owners that are never shared with the users of the information. Blockchain can disrupt all of these activities. It gives users control over their own information, and exactly where it resides. No platform is accessible without permission. Users can decide who can access their information. They can deal directly with advertisers and third parties as they choose, rather than like others. Furthermore, users can choose to share their information with advertisers on any platform and receive fees. In real life, some singers have begun to use blockchain technology to collect fees for songs and albums, rather than through any other intermediary.
I will give you a blockchain media I have used as an example. Most blockchain media have this similar model. I like to speculate in coins, and then I learned about the app Mustard Circle. His operating model is that anyone can create a circle by himself or join other people's circles through some methods. The circle owner can publish some news in the circle and repost some content related to the circle, such as movies, Bitcoin, and stock trading. Then the members inside can receive this information. If those users feel valuable, they will stay in the circle. Then with the user group, the circle owner can set up paid content, such as paying 5 yuan to read this information, or receive rewards. This is the simplest way to make money from blockchain media. Of course, blockchain is a very important technical foundation, and these media are only based on blockchain technology. Their profit methods are of course more complicated than what I said, and the profit methods of different blockchain media are also different.

Nowadays, blockchain is being used more and more in real life, and there are more and more ways to implement it. Just pay attention to the news and actual facts. I hope it canHelp you.

⑷ How can blockchain technology be combined with the content industry

First, blockchain + content production.

The application of this model is mainly to create a platform. Use blockchain technology to track, confirm and audit the transaction data of jointly created works, establish a blockchain co-creation platform, and solve the problems of copyright protection and profit distribution.

Second, it is blockchain + content circulation.

This model is mainly applied to copyright circulation platforms such as pictures, music, movies, and written works. Use blockchain technology to solve the problem of rampant piracy in the Internet era, promote the spread of traceability technology, and support on-chain traceability and identification. For example, the Primas project in the field of digital copyright uses cryptography and blockchain technology to encrypt the author's work and time, author information, and timestamp to generate a unique eight-digit code, so that no matter where the content "flows" later, No matter where you are, there are roots that can be traced.

Third, it is blockchain + content trading.

Use blockchain technology to issue digital assets and conduct copyright transactions and game prop scene transactions to promote safer and more reliable transactions in the traditional content industry.

Fourth, it is blockchain + content rights protection.

This mode is mainly used for notarization and file storage. Utilizing the multi-center anti-credit and trustworthy features of blockchain technology, the direct use of documents on the chain can be evidence of notarization.

⑸ Blockchain opens the "big copyright era" with value

With the development of the Internet, the digitalization process of the cultural industry has accelerated, and traditional copyright technology has been unable to meet the needs of copyright protection. The industry believes that in order to cope with the copyright protection challenges brought about by digital development, in addition to national policy guidance, the application of new technologies such as blockchain and big data will also play an important role. Recently, Xinhua News Agency China Picture Group stated that it will join hands with the DCI system to build a national imaging copyright service platform that integrates new technologies such as blockchain and digital watermarking.

In fact, in recent years, the country has continuously introduced various policies to support the development of the blockchain industry and encourage the innovative application of blockchain technology.

In 2016, the State Council issued the "Thirteenth Five-Year Plan for National Informatization", which for the first time included blockchain into the category of new technologies and made a cutting-edge layout.

On March 13, 2021, the "Fourteenth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals for 2035" was announced, and blockchain was listed as one of the seven digital economies. One of the key industries.

On July 16, 2021, the People's Bank of China released the white paper "Research and Development Progress of China's Digital RMB". The data shows that as of June 30, 2021, the digital RMB pilot scenario has exceeded1.32 million, covering living payment, catering services, transportation, shopping and consumption, government services and other fields.

Recently, there is constant news about the positive development of the copyright industry and the innovation and development of blockchain technology. First, the China Copyright Protection Center will cooperate with Huawei to build my country's independently innovative DCI (Digital Copyright Identifier, Digital Copyright Unique Identifier) ​​system and create a new ecosystem for the Internet copyright industry based on blockchain technology; second, Xinhua News Agency China Picture Group said , will join hands with the DCI system to jointly explore innovative research in the field of image content copyright in the 5G era, build a national image copyright service platform, and jointly build a new ecosystem for Internet visual copyright transactions.

The "Blockchain Digital Copyright Asset Transaction" channel jointly built and promoted by Alibaba Auction and Xinbian Chain was also launched nationwide recently and started previewing. The Alibaba auction platform is an innovative application of blockchain technology in the digital copyright industry. According to reports, the "Blockchain Digital Copyright Asset Transaction" project provides copyright owners engaged in literature, games, animation, music, art, etc. with the verification and on-chain transactions of digital works based on the "New Version Chain". The copyright of the work generates a unique digital copyright asset certificate in the "New Edition Chain". After the transaction, the legal holder of the copyright asset certificate will have all rights except the signature right of the digital work.

It is worth noting that the national image copyright service platform created this time will use new technologies such as blockchain, image invisible digital watermarks, network-wide image copyright detection, big data, and artificial intelligence. The industry believes that digital watermark technology can currently be used in eight scenarios, including radio and television content monitoring, media asset retrieval, film and television drama review and leakage prevention, advertising monitoring and statistics, movie projectors, Internet copyright protection, military information confidentiality, and IP product anti-counterfeiting. , the cumulative market size exceeds 2 billion yuan. The absolute advantages of technology and resources are obvious, and the revenue scale of digital watermarking business is expected to expand significantly in the future.

Blockchain naturally solves the ownership confirmation problem in the information storage process based on mathematical principles. The recording, transmission and storage results of copyright information are all effective and credible. Once produced, the information recorded in the blockchain will be permanently recorded and cannot be tampered with. Only by possessing more than 51% of the computing power of the entire network can it be possible to modify the relevant copyright information.

In traditional intellectual property rights protection activities, a series of phenomena such as low execution efficiency of third-party agencies, difficulty in obtaining evidence, high costs, low compensation, and long cycle are common. In the information exchange and interconnection in the blockchain global network, efficiency can be greatly improved without the need for third-party processing. Generally speaking, blockchain solves the problem of being unable to tamper with registration time and content, while digital watermark technology solves the problem of providing evidence.

Relevant personnel of Hanbang Hi-Tech once compared: “I discovered that someone was piracyMy content contains my watermark, which can provide evidence to prove the problem of piracy and copyright. ” Analysis by industry insiders pointed out that if watermarks are put on the chain and blockchain + digital watermarks are combined, the core pain points of cumbersome confirmation of rights in the original copyright protection technology can be perfectly solved, and it has high technical value.

Blockchain is closely related to our future. This is an imaginative concept. Many people think that blockchain is only related to digital currency, but the actual scenes of exposure to blockchain may occur more in: health Code, online ride-hailing, stock trading... In fact, blockchain and its technology-derived applications can be said to be the hottest emerging industries at the moment.

Blockchain cannot represent the future, but its There are huge possibilities in the future. Regarding the application scenarios of blockchain technology in copyright protection, what still needs to be done is to conduct in-depth research on the core technology of blockchain and understand the application nature of blockchain-enabled industries. Apply the technology in place and process it well Standardize and focus on on-chain information security, and truly and effectively implement it in the physical field, ushering in a new era of rapid development for future industrial blockchains.

⑹ Blockchain: the "gold nugget shovel" in the post-Internet era ”

Text\Meng Yonghui

There is a very famous line in the movie "The Godfather": Great people are not born great, but show their greatness in the process of growing up. . Contrary to this line, the blockchain has been destined to have a glorious and great life from the moment it was born. Mysterious preachers, fanatical supporters, cryptic fearers... many are different from each other. Words related to blockchain are mixed in. For a while, blockchain has already transcended its own meaning.

Just like every time when the trend comes, there will be speculators involved, blockchain The coming of the storm is no exception. Capital's huge expectations for the blockchain era, entrepreneurs' all-out efforts on blockchain, and the market's complete emphasis on blockchain are all making this originally mysterious and slightly obscure word appear again and again. In front of people, so that people forget that its "matrix" has not yet been generally recognized in the real world.

There is no love without reason, and there is no hatred without reason. People's concerns about blockchain technology Love and hate also reveal the complex relationship between them that is constantly cut and confused. The popularity of the blockchain era is no accident, just as the city of Rome was not created in a day. It is always possible to explore the underlying reasons for the popularity of the blockchain. Find a sudden enlightenment that makes us see the sun through the clouds. So, why is blockchain technology so popular?

Everything has a cause and effect, and the popularity of blockchain is not accidental

When the Internet is booming As the current rushes away, in addition to the colorful shells left on the beach at low tide, there is also the huge expectation of the people who pick up the shells for the coming of the next tide. When the moment of great change comes, people begin to look forward to picking up the shells at the next high tide. To updateLots of shells.

No matter from which angle you look at it, the Internet era is an era worth remembering. In this era, people's lifestyles have changed more profoundly than in any previous era. It is foreseeable that this era is destined to become a bright spot in the vast history, leaving an indelible impression on people.

Everything great must have repercussions. The changes brought to us by Internet technology make us full of expectations for the next wave of technology. After experiencing the double baptism of the traditional Internet era and the mobile Internet, people's lives have undergone earth-shaking changes. Today's Internet has become an infrastructure like water, air, and electricity. All aspects of people's lives are connected to the Internet, and it has fundamentally subverted people's original lifestyles.

It is precisely because the Internet technology is so great that it has strengthened people’s confidence in looking for the next technology to subvert or optimize the existing lifestyle and industry logic, trying to find new developments through the blessing of new technologies. direction. The emergence of blockchain technology is like a dry land that has not rained for a long time. A spring rain awakens people's hearts.

The expectations for blockchain technology are no less than those of the Internet era. In that era, there were always many steadfast believers and practitioners. It was they who devoted themselves to the wave of Internet entrepreneurship that made the Internet The era saw the emergence of trend-setters who dared to ride the wind and waves, and truly became the winners of that era with their gorgeous and colorful dances. Whether they are Internet giants or unicorn companies, they are the huge wealth left to people in the Internet era. Perhaps it is precisely because of this that people are full of expectations for the arrival of the next wave of technology.

It’s hard to be perfect. The Internet's tentacles have not yet reached unknown areas that have opened up space for people's imagination. Although Internet technology has penetrated into every corner of people's lives, simply adding Internet technology to the industry cannot bring changes to the industry. The industry needs more in-depth technical participation to find an entry point to subvert the original business logic. . The emergence of a mysterious figure named Satoshi Nakamoto broke this silent situation. His mystery just increased mankind's huge curiosity about exploring the unknown world.

Although Internet technology has opened the key to a new life for us, after opening the door to a new life, people still need to work hard to find the true meaning of the new life. How to find the true meaning of a new life, relying solely on the Internet can no longer play a corresponding role. Blockchain is the shovel that allows people to truly find the true meaning of life. Through it, people may be able to find the life they really want.

The popularity of blockchain is just like Rome was not built in a day. The needs of the industry, the blessing of technology, the promotion of capital, and the needs of users are all the reasons for the popularity of blockchain. As people's research on blockchain technology continues to deepen, aA bright picture painted by blockchain technology may slowly unfold, and a new era will come.

Under the sky of history, what is the new era opened by blockchain?

The huge changes that the Internet era has brought to people’s lives have allowed us to see the tremendous power that the blockchain era will bring to our lives. So, what kind of era will the blockchain era usher in? What kind of life will we get in the blockchain era?

Blockchain technology will make decentralization in the Internet era truly possible. Although deintermediation in the Internet era has improved the efficiency of all walks of life, this deintermediation is about establishing a platform and a center. The current traffic giants are the inevitable result of the de-intermediation development in the Internet era. This approach of establishing a new center to achieve the effect of de-intermediation can only bring changes to the development of the industry on a relatively superficial level. This change does not count as true disintermediation; it leads to the formation of a new center.

Through blockchain technology, we can truly achieve disintermediation and decentralization, that is, our individuals have truly become individuals participating in the operation of the industry. In a sense, the advent of the blockchain era has made deintermediation possible, and may even make it possible for the Internet giants that are currently in full swing to be circumvented. Users and industry participants have truly become the core elements of industry operations, and truly seamless connection can be achieved through blockchain technology.

Blockchain technology will make many beautiful visions of the Internet era possible. As an external technology, Internet technology uses one technology to adapt to all external industries and establishes new centers one after another based on each industry. These new centers are unicorn companies in the industry or Internet traffic giants. In essence, Internet technology cannot change the industry itself.

In the Internet era, we will try to use the Internet to bring about changes in the industry itself. However, as it develops, we find that simply adding the Internet cannot bring changes to the industry. , we must start from the technology of the industry itself to bring real changes to the development of the industry. Blockchain technology can start from within the industry and bring about internal changes in the industry by changing its own elements, thereby solving pain points and problems that cannot be solved in the Internet era with the help of blockchain technology.

In a sense, the advent of the blockchain era will fundamentally change many of the impossible pain points and problems in the Internet era. As blockchain technology becomes increasingly integrated with external industries, especially as "Blockchain+" gradually takes shape, a new era of blockchain will come.

Blockchain technology will fundamentally change the original industrylogic. In the Internet era, technology plays the role of an external intervenor, and it itself does not have many applications for the industry. After entering the blockchain era, we can remix and adjust the original industry operating logic, ultimately causing fundamental changes in the industry itself.

It is worth noting that blockchain technology is changing on the basis of inheriting the legacy of the Internet. The use of blockchain technology only changes the operating logic of the crude oil industry, and its application needs to take advantage of the Internet era. One of the important reasons why technology companies represented by Tencent, Facebook, and Meitu took the lead in entering the blockchain field is that they have accumulated many advantages in the Internet era, and these advantages give them the ability to make changes.

By changing the operating logic of different industries, the blockchain era will form a new era that is truly user-centered. The common connection between users and industry elements will make the industry’s original Make changes logically and truly form a business model that conforms to the operating logic of the blockchain itself.

The advent of the blockchain era has opened up a strange and wonderful picture for us. The swarming wave of the Internet era has made the entire blockchain face a diversified development pattern. As blockchain technology develops and matures, the industry structure centered on Internet giants formed in the Internet era will be broken, and a new era of deintermediation will truly begin.

⑺ A hundred schools of thought contend | Cai Dong: The "Truman Show" hidden under blockchain technology

About Blockchain The discussion of chain application has 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 life on the chain be a beautiful credit society like the "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 maturity and application level of blockchain technology. 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 decentralization of blockchain (large number of viewers), openness and transparency (thisFrom time to time, unsettling features emerge from its technical features that cannot be tampered with (cannot be hidden). 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 businesses 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 blockchain applicationsThe most mature Bitcoin, 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 active creation in the entire entertainment industry. , produce high-quality content, but it is difficult for users to change their habit of listening to music on centralized platforms in a short period of time. Vested interests in these fields will also be "taken away from the cake". For example, the traditional ticketing market will be challenged. , and may also lead to 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 will 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
