⑴ Dr. Wei Jianping: What can blockchain technology bring to urban management

On September 18, Dr. Wei Jianping, senior vice president of Times Lingyu, was invited to attend the "2020 Cloud Qi Conference·Ant Chain Industry Application New Model" roundtable dialogue, with leaders from various industries such as Ant Group and e-Shanbao, shared the role that blockchain technology can play in urban management and the convenience it brings to the people, and talked freely How to use digital technology to drive application innovation and industry progress.

Dr. Wei Jianping said that making urban life better through the innovative application of information technology is the corporate mission that Times Lingyu Company has always adhered to, and the company is constantly exploring innovative applications of blockchain technology in the field of urban management. Urban management involves many fields, and it also provides a wealth of application scenarios for the application of blockchain technology.

When discussing the prospects of blockchain technology for future industrial upgrading and industry applications, Dr. Wei Jianping pointed out that the application of blockchain technology has broad prospects in e-government fields such as urban management.

First of all, the concept and technology of blockchain can break down line divisions and data silos, promote further optimization of business processes, provide governments at all levels with new technical tools, collaborative platforms and infrastructure, and promote Cross-level, cross-department, and cross-region data sharing; secondly, it helps to establish a data trust mechanism to ensure that trusted data is authentic, non-tamperable and traceable; finally, it can solve the problem of status information, certificates and licenses of various subjects in the government field. Frequent changes in data, etc., make it difficult for relevant parties to obtain and verify information in a timely manner, promote the process of government information disclosure, and comprehensively improve the overall level of government services.

Dr. Wei Jianping emphasized that to completely change the current decentralized construction model of my country's government service system and achieve the goals of data sharing and collaborative application in large-scale government affairs, further integration is needed, including district offices. The new generation of information technology, including search link technology, achieves innovation and breakthroughs in technical systems and application practices.

⑵ How blockchain technology opens up an unimaginable new world

The concept of blockchain first appeared in the early 1990s. In 1991, several scientists described the first data block application based on cryptographic technology, which implemented a distributed file system and used document timestamps to prevent file tampering, forgery, and denial. In 1992, improvements were made on this basis, combining multiple document certificates into one block to improve file recording efficiency. With the development of the Internet, in 2008, based on the above examples, Satoshi Nakamoto proposed an electronic currency mechanism that relies on cryptography and calculation methods. This method is also the core of the blockchain. In layman's terms, it means that the other party can be exchanged without knowing the other party. Transactions can be conducted without the need for third-party intervention.

Information contains all the contents of value transmission in human society. Since the emergence of human beings, information has been the first priority for human development.driving force. Several important stages in the development of human society were driven by the information revolution. For example, writing promoted the invention of tools, and the Renaissance promoted the development of capitalism and natural science. These revolutions all reflect the importance of informatization. In today's digital era, blockchain has brought us the fourth industrial revolution, and according to its characteristics, it ensures the authenticity and traceability of data, and can be extended to many fields such as the Internet of Things and smart manufacturing. Bringing about the integration of informatization and industrialization.

⑶ Blockchain opens the "Great 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". Data shows that as of June 30, 2021, there have been more than 1.32 million digital RMB pilot scenarios, covering Living payment, catering services, transportation, shopping 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 Trading" project is for those engaged in literature, games, animation,Music, art and other copyright holders provide digital works with asset verification and on-chain transactions 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 pirated my content and included my watermark. This can provide evidence to prove the problem of piracy and copyright confirmation." Analysis by industry insiders It is 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. It is an imaginative concept. Many people think that blockchain is only related to digital currency, but actual exposure to blockchain may occur more in: health codes, online ride-hailing, stock trading... In fact, blockchain and its technology Derivative applications can be said to be the hottest emerging industry at the moment.

Blockchain cannot represent the future, but its future has great possibilities. 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. The technology application will be done properly, the process will be standardized, the information security on the chain will be solved with key points, and it will be truly and effectively implemented in the physical field, so that the future industrial blockchain will usher in rapid development.A new era of development.

⑷ What are the application examples of blockchain technology

The express logistics industry is an industry that is very suitable for the application of blockchain technology.

In fact, the logistics ecosystem is relatively complex and there are many groups involved in the process.

The industry itself is a complex of segments with the concept of "flow". Starting from the initial "business flow", it gradually gave birth to "logistics", as well as the corresponding support of "capital flow" and "information flow" , complete the service chain.

There is a key issue behind the emergence of various "flows", which is the transfer of commodity ownership.

Coincidentally, many of the types of problems that blockchain technology solves are related to the trust friction generated during the transfer of asset ownership.

The application of blockchain technology can significantly improve the processing speed and efficiency of settlement business in the express logistics industry, effectively solve the problem of traceability and anti-counterfeiting of items, and fully ensure information security and the privacy of senders and recipients.

In the field of promoting application in the express logistics industry, there are domestic blockchain companies doing applications in this area, such as Walton Chain.

Last year, Waltonchain reached a strategic cooperation with Huodou (Xiamen) Technology Co., Ltd., using Waltonchain’s “RFID blockchain” technology solution to help it improve its logistics solutions and move goods to Dou puts data on the chain in all aspects of its logistics turnover, such as entering and exiting the warehouse, receiving goods and other key nodes. After deploying the reading and writing system, when the object passes through any link, the relevant data can be read by the RFID reader and writer, and the relevant data can be read by the RFID reader. The corresponding behavior is converted into data and uploaded to the blockchain. Users can trace the entire logistics process with one click.

Four business scenarios that can be implemented in the real environment are suitable for the application of blockchain technology.

Scenario 1: Insured express delivery

Revolving around the insured scenario, express companies transport goods, insurance companies provide guaranteed goods, merchants provide goods sales, sellers purchase insured services, and the government regulates the industry.

So, what should be recorded on the blockchain? There are several key points. The logistics details of the goods, accounts, identities, claims, other reference data and other information are recorded on the blockchain.

Insured price is the concept of a contract. When the customer signs for the package normally, the account claim is automatically triggered, the contract ends normally, and the premium is automatically cleared. If there is a problem or missing piece, the insurance company's claim process will be triggered.

Scenario 2: Charity express delivery

For charity activities, such as the "One Cent" campaign, one cent from the cost of each charity package is donated to the account of the charity organization . In this scenario, the express delivery company is still responsible for the transportation of goods, the public welfare organization provides the execution of public welfare activities, and the poverty alleviation merchants provide the sales of public welfare and poverty alleviation products.

Then what is recorded in the blockchain is the logistics details of the goods. After the package is signed for, it will be recorded on the blockchain, automatically triggering a transfer from the logistics company's public welfare account to the public welfare organization's account. After the charity activities are over,The entire process is open and transparent, avoiding public distrust in social welfare activities.

Scenario 3: Industry blacklist sharing

At present, the blacklist of express delivery employees is still mainly offline. We hope that through blockchain technology, each company can record the blacklist of employees on the blockchain, and other companies can also query it, and the data cannot be modified, and can be traced back to which company this person worked in What kind of inappropriate behavior and other information.

Scenario 4: Supervision of safety incidents in postal delivery channels

Many express companies will install security inspection machines, and the government also wants to know whether each logistics company has any transportation safety hazards. Through the distributed accounting model, each express delivery company can record the effective information of the security incident on the blockchain when a security incident occurs, so that regulatory agencies can monitor it in real time and cannot be tampered with.

⑸ How does blockchain technology “show its mettle” in the military?

In recent years, the application of blockchain technology has attracted widespread attention, whether in the financial field, enterprises, or Government departments are accelerating the research, development and application of blockchain technology. Some countries have also sensed the potential of blockchain technology in warfare and are striving to expand the breadth and depth of blockchain technology in military applications.

Blockchain technology is the "bulletproof vest" for military logistics. The decentralized nature of blockchain technology gives it a strong ability to recover information after an attack. Unless all computers in the system are destroyed, it is completely meaningless to modify the information of a node because the system can quickly recover. Complete form. The current logistics system relies too much on the reliability of the information service center. Once the information service center fails, it will affect the normal operation of the entire logistics system. Military applications have very high requirements on system security and wartime damage resistance. The use of blockchain technology can effectively solve the core issues such as information security, data storage and interactive processing faced by intelligent military logistics. The focus is on improving the logistics system. survivability, thereby ensuring the orderly and efficient operation of the system.

Essentially speaking, blockchain technology is a mutually trusted storage device that can be used for information transactions between multiple users. Its core is "distributed consensus" and "anonymity". Transactions can be verified at any time without affecting the privacy of the parties involved. Therefore, blockchain technology is bound to become a new generation of disruptive technology, and its military applications will become more extensive and in-depth.

⑹ Is Bitcoin a "fairy" or a "demon"? Who can seize the myth of wealth creation

Text: Shi Yan

p>

Bitcoin has frequently hit the market recently. In addition to the eye-catching wealth-making stories, the "roller coaster" market is coming again. As human beings, we also want to pry into the mysteries of Bitcoin. Many people have only become aware of Bitcoin in recent years, and currently Bitcoin is not an investment object that ordinary people can control. But if another new thing like "Bitcoin" comes, can weDo you want to take a ride on wealth as early as possible?

On February 22, 2021, Bitcoin hit a record high, with each bitcoin worth up to US$58,000, and the total market value exceeded US$1 trillion. The rapid rise from US$30,000 to US$58,000 took only about 50 days, drawing a steep K-line chart.

On February 26, some media revealed that the U.S. Securities and Exchange Commission planned to investigate Musk for allegedly using his celebrity influence to cause the rapid rise in prices of virtual electronic currencies such as Dogecoin. As soon as the news came out , the price of electronic currencies led by Bitcoin plummeted.

As of 15:30 on February 28, Bitcoin dropped rapidly to around US$44,000. Within a day or so, about 96,000 people were liquidated, with a total liquidation amount of approximately US$668 million.

Bai Shipan, a visiting professor at the National University of Singapore, pointed out that the total amount of Bitcoin is fixed, and currently production has slowed down. Many institutions have participated in investment, which has promoted the rise in Bitcoin prices. A few large players are controlling most of the Bitcoins. The market lacks transparency and prices are easily manipulated by large players. The fluctuations are violent. For ordinary traders, the risks are very high.

About ten years ago, someone used Bitcoin to make a purchase for the first time, and only exchanged 10,000 face value Bitcoins for two pizzas. Today, 10,000 Bitcoins is more than 400 to 500 million US dollars. How many times has it increased? During the skyrocketing price of Bitcoin, many wealth creation myths have been interpreted.

Is it a "fairy"?

In 2008, a person named Satoshi Nakamoto (the real person has never shown his face) published an article "Bitcoin: A Peer-to-Peer Electronic Cash System" on the Internet. , Bitcoin began to conquer the world.

Bitcoin is the first successful application of blockchain technology. It brings blockchain technology into the public eye. Today, blockchain technology is not only used in the financial industry, but also widely used in e-government, intellectual property, electronic certificate deposits and other industries.

In summary, Bitcoin is a virtual electronic currency based on blockchain technology. It is a currency generated by a program. It is generated according to the rules of the program and has the following main characteristics:

< p> 1. The total quantity is limited and over-issuance will not cause inflation. After every 210,000 blocks are created, the production quantity will be halved. Now, halving has occurred twice. According to the algorithm, production becomes more and more difficult as the blocks are later. By about 2140, the total number of Bitcoins will reach 2,100. 10,000, no new Bitcoins will be produced in the future.

2. It adopts distributed accounting method, which is decentralized and does not require an issuing agency. As long as you log in to the Internet, you can conduct global transactions.

3. No government permission is required, and unlike traditional currencies, no bank participation is required.

4. Strict encryption algorithm makes it impossible for anyone to forge, making transactions convenient and safe.

5. Good anonymity, which protects the privacy of the transaction parties. The currency only recognizes technology and does not identify the owner, nor does it care about the identity of the account owner. It does not need to be bound to a bank card, and transactions with strangers are free. This feature is favored by both buyers and sellers in illegal transactions.

Is it a "demon"?

Bitcoin also has shortcomings:

1. In the Bitcoin “mining” farm, a large number of “mining machines” are operating. These machines are high-performance special computers that use The chip performs a lot of calculations. Theoretically speaking, with more high-performance mining machines, the more minerals can be mined. During the operation of these machines, they dissipate huge amounts of heat, so it is often seen on the mining machines and on the shelves of the mines, a large number of The fans are running, and some mines are simply built next to power stations, investing huge hardware costs and consuming a lot of electricity to mine Bitcoin.

2. As Bitcoin became known to the public, many speculators blindly speculated, and the price of Bitcoin jumped up and down, gradually breaking away from the stability characteristics of currency. Taking the same route as speculative products, some experts believe that, just like the tulip hype, Bitcoin will fall from the altar sooner or later.

3. The anonymity of transactions is a favorite of black transactions. If Bitcoin is used as a ransom in some criminal acts, it will become more difficult to solve the case.

4. If the total amount of Bitcoin is fixed, it will only cause the value to continue to rise. Many people will hoard and expect the value to rise. As a result, the liquidity will be greatly reduced and the circulation function of currency will be lost.

Bitcoin has the characteristics of fixed total amount, anarchy, and anonymity. Bitcoin is very popular in the black market and dark network, so various countries have adopted policies.

The regulation of virtual currencies such as Bitcoin in various countries is generally divided into three types:

1. Strict control. For example, China, Russia and other countries.

In December 2013, the People's Bank of China and five other ministries and commissions jointly issued the "Notice on Preventing Bitcoin Risks". The article made it clear that Bitcoin is only a specific virtual commodity and does not have the same legal status as a national currency. It is strictly prohibited to be used as currency in the market.

2. Take restrictive measures. The United States requires relevant institutions to operate with licenses, but licenses are issued very cautiously and in small quantities; South Korea prohibits anonymous transactions in order to prevent money laundering and other crimes, and the Japanese government strictly requires exchanges to implement anti-money laundering measures.

3. No restrictions. For example, in Singapore, only business registration is required. Many innovative blockchain companies go to Singapore. Some people say that Singapore is a paradise for virtual currencies. Many virtual currency ICOs are held in Singapore.

Fu Qiang, associate professor at the National University of Singapore Business School, believes that Bitcoin is a risky asset. Bitcoin is on the opposite side of the legal currencies of various countries. It is likely to be more strictly controlled by governments in the future, and investors need to be highly vigilant. risk.

Kaiyuan Securities analyst Zhao Wei pointed out that gold and U.S. bonds can become high-quality safe-haven assets because of their price stability, strong liquidity, large market capitalization and other factors. Compared with risky assets, gold is a safe-haven asset. The characteristic of insurance is also the ability to hedge risks. Compared with gold, Bitcoin's price fluctuates greatly, its liquidity is weak, and its market value is small. Looking at historical data, when risky assets fluctuate violently, Bitcoin often falls sharply, often moving in the opposite direction to gold, and its performance is far behind that of gold and other safe-haven assets.

In addition, gold can not only be made into jewelry that people love, but it is also an important raw material in industry. It is widely used. Instrument manufacturing, electronics industry, aerospace industry, etc. are all inseparable from gold. However, Bitcoin In addition to being a virtual currency, what else can coins be used for? Its price is completely speculated by buyers and sellers.

The entire industry chain has the myth of wealth creation

Whether it is a "fairy" or a "demon", Bitcoin has created many rich people. I often see news reports that someone born in the 1990s has become a rich man because of Bitcoin. Many people envy and want to become these rich people.

Bitcoin has been developing for many years, and all links have grown in scale. These links form a huge Bitcoin industry chain. At present, the entire Bitcoin can be divided into invention, mining, transaction, service and other links, and super rich people have appeared in each link.

1. Invention

In 2009, a person named Satoshi Nakamoto published the design idea of ​​an encrypted electronic currency for the first time and named it "Bitcoin". According to the analysis of Bitcoin expert Sergio, Satoshi Nakamoto was the first miner. He mined about 1 million for the first time. In the following ten years, Satoshi Nakamoto may have continued to increase the number.

Satoshi Nakamoto, the inventor of Bitcoin, has theoretically become the richest man in the world. Satoshi Nakamoto is proficient in computer programming, encryption algorithms, electronic currency and other technologies. He is a genius across multiple industries. Such a genius should also receive huge wealth. Now, blockchain technology is accelerating its application in all walks of life, bringing huge social benefits.

2. Mining

Bitcoin mining machines go through several stages: server mining graphics card mining FPGA mining ASIC special chip Mining Army Mining

Ten years ago, the author bought some servers from the Internet and planned to mine Bitcoin. However, at a class reunion, he was laughed at by his classmates and missed out on becoming an early miner. It seems that "the truth is in the hands of a few people" may be correct, because at that time mostNo one is optimistic about Bitcoin.

As the upstream equipment of the Bitcoin industry chain, Bitcoin mining machines have also experienced periods of huge profits and stable periods. Sometimes, like Bitcoin, they have experienced hell and heaven.

On January 4, 2009, the popular mining period of Bitcoin began; in September 2010, because graphics cards are good at parallel computing, mining machines with full graphics cards became popular; in early 2013, the development of dedicated ASIC chips Mining machines appeared, and the era of ASIC mining machines came.

According to online information, Carlson founded the largest Bitcoin mining farm in North America and was the first miner to become a millionaire.

Large-scale Bitcoin mining farms often have rows and rows of shelves filled with high-speed mining machines. These professional mining machines are generally sold on major e-commerce platforms. Professional mining machine manufacturers have also become a wealth-making base.

According to statistics, in the 2019 Hurun Rich List, the number of blockchain practitioners on the list reached 15, of which five are engaged in mining machine production.

3. Bitcoin trading

In business all over the world, if you dare to try new things, you will be unbeatable only if you are early. If you are early in Bitcoin trading, If you can calm down and hoard coins, most people will make a lot of money.

In fact, people who trade Bitcoin can be roughly divided into four categories:

(1) Those who close their hands in time

There are also friends around, and they have been exposed to Bitcoin relatively early. With a playful attitude, I invested a small amount, but ended up selling after the price surged to more than 10,000 yuan. Some investors also profited and exited early due to the early plunge. They found that Bitcoin continued to surge, but they did not dare to chase the high. As a result, , simply stay away.

(2) Short-term speculation type

Some people buy Bitcoin, just like stock speculation, they like short-term speculation, buy and sell back and forth, and are very busy, only to find out , often not following the correct rhythm, not many people make money, and even many people lose money. There are also some masters who repeatedly sell high and buy low, and have gained a lot of money.

(3) Grievance type

Some people dare to try new things and buy some early, but forget their passwords. The Bitcoin wallet only recognizes the password, not the person, and is equivalent to a waiter.

(4) Long-term holding type

There are also some investment experts who hold Bitcoin for a long time. There are not many such people. The belief that allows them to persist in long-term holding is that Bitcoin The number of coins is fixed and will become more valuable as global investors participate. As a result, these types of people are perfect players, hoarding Bitcoin for a long time and gaining huge wealth.

4. Bitcoin services

Bitcoin is popular, and the service industry is also very profitable, such as electronic currency issuance platforms and trading platforms. Often the platforms are engaged in both issuance and trading. Therefore, some people Huge profits were made.

The transaction fee of the Bitcoin platform starting with H is 0.2%. If the transaction value of one Bitcoin is 100,000 yuan, then 200 yuan will be deducted for one transaction. Therefore, the platform, like the stock market exchange, encourages and hopes that everyone will trade frequently. Regardless of whether traders make money or lose money, the platform makes money, and the founding team of the platform also makes a lot of money.

5. Others

Many business celebrities have also participated in Bitcoin investment, which has greatly increased the popularity of Bitcoin.

In December 2013, according to information released by Hong Kong's "South China Morning Post", "Superman" Li Ka-shing invested in companies engaged in Bitcoin business through his companies, and the amount of investment was unknown. Many investors followed Li Chaoren's lead, and Bitcoin surged. Some media said that Li Chaoren made huge profits as a result.

Tesla CEO Musk vigorously promoted Dogecoin on the Internet. As a result, Dogecoin and Bitcoin soared, and Musk made a fortune. Then, there were reports that the U.S. Securities and Exchange Commission Rendezvous will investigate Musk. As a result, the virtual currency market plummeted. Some netizens also suspected that Musk ran away early after making a fortune.

What abilities do rich people who rely on Bitcoin to make a fortune need? The first is to have a long-term investment perspective. Ten years ago, when most people couldn't see clearly about Bitcoin, you had to be optimistic about it and have firm confidence, because Bitcoin is a good speculative product, and the anonymity of Bitcoin makes it a favorite for black transactions... …

Next, find out what you are good at and participate in it, whether it is invention, mining, trading, service, etc. When others are not optimistic about it, stick to your own unique opinions and try to participate as early as possible. The cost will be very low.

We are watching the wealth train of Bitcoin become a crazy racing car, getting farther and farther away from ordinary people and unable to catch up. Therefore, we suggest that ordinary investors just watch how Bitcoin performs now. The most important thing is to study people who have gained huge wealth through Bitcoin, learn from their experiences, and look for new wealth trains in the future. Opportunities to make wealth will come sooner or later, and success always belongs to those who are prepared.

Dear readers, have any of your friends invested in Bitcoin? Have they succeeded or failed?

⑺ How blockchain technology empowers real industries

Now there are domestic companies that have implemented blockchain technology into actual industries. For example, Wanglian Technology has put blockchain technology into practice. The chain is applied to financial services, medical health, IP copyright, Internet of Things, sharing economy, communications, education,
social management, charity, culture and entertainment and other fields

⑻ Blockchain technology, in the end Is it a devil or an angel?

Both good and bad are more good and less bad

Blockchain technology, in the final analysis, is the sharing of information and data.

Who has mastered this technology?, whoever develops economic and trade exchanges will have the initiative to do business.

Its characteristics are: unforgeable, leaving traces throughout the process, traceable, open and transparent and collectively maintained.

Therefore, both devils and angels will use blockchain to serve themselves. It’s just that whoever has advanced technology and is powerful will be at the top.

Aren’t each of us the incarnation of devils and angels? ? What's more, it's a technology? The key depends on how you use it,

Technology is neutral, neither an angel nor a devil. The key is who controls it. If angels dominate, the world will become a better place. If the devil dominates, it will be hell on earth.

In essence, blockchain is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces", "traceable", "open and transparent" and "collectively maintained". ” and other characteristics. Based on these characteristics, a solid foundation of "trust" has been laid, a reliable "cooperation" mechanism has been created, and it has broad application prospects, especially in the financial field, which will bring unprecedented experience to people.

Blockchain technology is an advancement in network development and is widely used in the military. It is not available for civilian use yet. It is also not suitable for civilian use in our country. Therefore, if it can be used, it is an angel

Blockchain technology is neither an angel nor a devil. At present, this confidentiality and sharing technology is relatively advanced, but it is a bit untimely. Soon will be quickly eliminated in the future!

First of all, let me explain the general meaning of blockchain technology: blockchain is a distributed shared ledger and database, which is decentralized, cannot be tampered with, leaves traces throughout the process, can be traced, and is collectively maintained. , openness and transparency and other characteristics. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

To put it more straightforwardly, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. (A rougher understanding is that the main business of this technology is encrypted files and the side business is virtual currency)

One of the biggest hidden dangers is the birth of commercial quantum computers

1 , Since IBM announced the launch of the first commercial quantum computer in early 2019, the possibilities of micro personal quantum computers have become infinitely magnified. If anyone still doesn’t understand why quantum computers are mentioned here, then I can tell you responsibly that the power of quantum computers is that currently the most difficult passwords are as blank as a blank sheet of paper in front of quantum computers.Fragile!

2. The uncertainty faced by the blockchain. Currently, mainstream scientists have proposed two solutions to the upcoming quantum computers. The first one: Tailor-made for quantum computers and rewriting blockchain technology. (Currently, I have only written an outline, but no specific details.) The second type: Write rules and regulations into the hardware of each quantum computer that is about to leave the factory, prohibiting the use of various modes to crack blockchain technology. (I personally don’t believe in the second method. Rules and regulations are easy to write and enforce on computers, but some countries basically have no credibility at all. It is inevitable that they will default on their obligations and even open a backdoor program on it...)

3. The relationship between blockchain technology and digital currency. Take the digital currencies issued by central banks of various countries as an example. They draw on part of the blockchain technology.
