Ⅰ Is blockchain technology a devil or an angel?

Both good and bad are more good and less bad

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

Whoever masters this technology will have the opportunity to develop the economy and trade, and 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. 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 early 2019 IBM announced the launch of the firstWith the advent of commercial quantum computers, the possibilities of micro personal quantum computers have become infinitely larger. 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 fragile as white paper in front of quantum computers!

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. Although the mechanism is independent and obviously has a higher security level than the blockchain, it also faces risks because this technology is also based on the current computer working environment. from.

Summary: The best technology is not perfect. In the future, digital currency will definitely replace the original paper currency, but future risks may arise due to loopholes. And it becomes even more dangerous...

The progress of science and technology1 is indeed accompanied by the rise of emerging industries and the decline of traditional industries. Be objective in understanding.

I don’t understand and am confused

Is the blockchain issue a technical job? I don't think so. I think it should be broken down from the perspective of the system of the universe, of which the solar system is a part. As for how to block other galaxies, astronomers are still in the process of brewing it. It is a matter of the future. What we have to do now is We can only start from the territory of the earth. The result is either a continent or a country. Of course, there are also the problems of the religious consciousness of numerous ethnic groups and nations, as well as the connection problems of blocks in people and things.

I haven’t quite figured out the content and meaning of blockchain yet. At present, it should be good

Ⅱ In what fields is blockchain suitable for application?

< p>The first one is the information security industry.
The second one is the bill business field
The third one is the payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the equity proof blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owners of equity can be confirmed.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and becauseBlockchain technology itself has the characteristics of large capacity, high-speed computing, security, and convenience, which has paved the way for the advancement and popularization of technology.

IV 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., through Waltonchain’s “RFID blockchain” technologyThe solution helps it improve its logistics solution and upload the data of the goods in all aspects of its logistics turnover, such as entering and exiting the warehouse, receiving goods and other key nodes. After laying out the reading and writing system, when the object passes through any link, it can be The RFID reader reads the relevant data, converts the corresponding behavior into data, and uploads it 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 automatic settlement of the premium ends. 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 the transfer from the logistics company's public welfare account to the public welfare organization's account. When the public welfare activities are completed, the entire process is open and transparent, which avoids the public's distrust of 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.

IV In addition to being used in virtual currency, blockchain technology can also be used in other areas

In addition to being used in virtual currency, blockchain can also be used in the financial field, digital currency, Securities trading, fund management, customer credit reporting and anti-fraud, digital points, etc. The usage rate of blockchain in our country is still relatively high at present. Maybe what we have heard the most before is the use of blockchain.Used in virtual currency.

In summary, in today’s society, blockchain technology has provided us with a wide range of help, and we must make good use of this Technology, use it in various related industries to make our industry develop faster and ensure the interests of our people.

VI What are the applications of blockchain industry

Take the tourism industry as an example. Blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, credit consumption management, Tracking pilots' professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumer points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.

VII Application of Blockchain in the Financial Field

1. Application and Development of Blockchain

Some Internet, Internet start-ups and traditional financial industries Started to try out applications in some projects

2. Domestic financial institutions are testing the waters of blockchain

Various financial institutions are testing the waters one after another, and they are basically in the conceptual experimental stage and have not yet reached a large scale. Commercial scale.

3. Panoramic view of blockchain application in the financial field

4. Ghostwriting

5. Digital bills

Bills are an important financial product in the financial market. They have dual functions of payment and financing. They are of high value and bear bank credit or commercial credit. Once a bill is issued, its face amount, date and other important information cannot be changed. Bills also have circulation attributes and can be accepted, endorsed, discounted, rediscounted, collected and other transactions within a specific life cycle. Once the transaction is completed, the transaction cannot be revoked. There are two characteristics in the circulation of bills: First, the circulation of bills mainly occurs through bank acceptance bills, and the number and circulation of commercial acceptance bills are small; second, each bank independently conducts credit granting and risk control on the bill business, and a single bank's Risk control results may affect other participants in the bill market transaction chain.

The experimental production system of the digital bill trading platform uses SDC (Smart Draft Chain) blockchain technology, with the help of homomorphic encryption and zero-knowledgeIt uses cryptographic algorithms such as proof of identity for privacy protection, uses the Practical Byzantine Fault Tolerance Protocol (PBFT) for consensus, and uses a see-through mechanism to provide data monitoring.

The experimental production system includes four subsystems: stock exchange, bank, enterprise and monitoring: the stock exchange subsystem is responsible for managing the blockchain and monitoring the digital bill business; the bank subsystem has Digital bills have business functions such as acceptance and receipt, discount signing, rediscounting, and collection and repayment; the enterprise subsystem has business functions such as issuance, acceptance, endorsement, discounting, and prompt payment of digital bills; the monitoring subsystem monitors the status of the blockchain in real time and business happenings

What are the applications of Ⅷ blockchain

A brief introduction to the application of blockchain technology in the financial field

1. The application of blockchain technology in the banking industry

The biggest feature of blockchain technology is decentralization, and this feature will bring great benefits to the banking industry. Reduce substantial costs.

First of all, decentralization means that the establishment of a trust mechanism between banking systems no longer requires an intermediary, saving intermediary costs.

Secondly, the development of digital currency will make it possible to realize real-time digital transactions in banks. For example, in bill transactions, bank bill transactions have always relied on a third party to realize the transfer of valuable certificates. Even electronic bill transactions require interactive authentication through information from the central bank's ECDS system. Blockchain technology can realize point-to-point transfer of value and no longer requires centralized system control. This not only speeds up the speed of ticket transfer, but more importantly, it can reduce errors caused by human factors and reduce processes. Naturally, it will reduce the bank's demand for personnel and save the bank's labor costs.

Finally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by central clearing, which is inefficient. Settlement through blockchain technology will greatly improve the efficiency of banks.

Blockchain technology also plays a major role in banks’ cross-border payment services. Today, when global trade is highly developed, cross-border payments are becoming more and more frequent, and banks often act as third-party services in cross-border trade, such as electronic transfers, asset custody, etc. However, cross-border payments generally take about 2 days to arrive, which is very inefficient and reduces the utilization of funds in transit. In blockchain technology, both parties of cross-border payments can be completed in a point-to-point manner, achieving round-the-clock payment and real-time arrival, thereby speeding up clearing and settlement, thereby improving the efficiency of bank processing business.

Another feature of blockchain technology is de-risking. Banks can build their own blockchain, which can ensure that bank customers’ transaction information and transaction records are true and valid and will not be compromised. Without any tampering, the bank can effectively identify the customer's information, understand all aspects of the customer's situation, identify the customer's abnormal transactions, and prevent it from being tampered with by the customer.Defrauded, criminal activities such as illegal money laundering and fund transfer can also be discovered in time, thereby reducing the bank's supervision costs.

2. Application of blockchain technology in the insurance industry

Blockchain technology also has incomparable advantages in the insurance industry. From the perspective of data management, the application of blockchain technology by insurance companies can effectively improve risk management and control capabilities, including the risk supervision of insurance companies and the risk management of policyholders.

The application of blockchain technology in the insurance industry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operating processes of insurance companies on nodes, and can achieve in-process control over the company's capital flow, investment status, compensation payments and other businesses, and improve the company's risk management and control capabilities.

In addition, blockchain technology is safe, reliable, and cannot be tampered with at will, ensuring that the information obtained by the policy holder is true and effective, thereby enhancing the policy holder's risk management capabilities.

3. Application of blockchain technology in the securities industry

The application of blockchain technology in the securities industry can increase the flexibility of securities issuance. Companies issuing securities can use smart contracts , by setting the method and time of securities issuance, securities can even be issued 24 hours a day under the most ideal condition.

Under the operation of smart contracts, automatic matching of buyers and sellers is realized, and settlement and clearing steps are automatically completed through the distributed digital registration system. The transaction records on the blockchain will not be changed arbitrarily, so the entered information actually has a publicity effect, so there will be no dispute in the stock exchange's ownership confirmation.

In addition, blockchain technology makes the securities trading process more open and transparent. Through blockchain technology, the securities industry does not need a central organization to operate and manage, nor does it require investment banks to underwrite, to achieve true peer-to-peer transactions, reduce illegal activities such as black-box operations and insider trading in securities transactions, and realize the control of securities. Effective supervision of the industry.

4. Blockchain technology and financial infrastructure

Blockchain technology uses a decentralized mechanism to exchange value, which will lead to a modern world characterized by centralization. Some financial infrastructures have undergone earth-shaking changes.

Assets such as collateral, pledges, stocks, bonds, and derivatives usually require a trustworthy central organization to register or keep them, but blockchain can record and save these in a new way. Product data will have an impact on the registration system for these products.

Blockchain can receive and react to information and value through smart contracts, automatically complete the transfer of value, and automatically complete transactions, clearing and settlement, which will impact the existing large-amount transaction systems and central banks. Existing financial infrastructure such as securities depository, securities settlement and over-the-counter derivatives trading.

5. Application of blockchain technology in supply chain

The application of blockchain technology in supply chain first provides credit guarantee.Recording the circulation information of commodities, etc., it can prove the authenticity and reliability of commodities and their circulation, thereby enabling a comprehensive evaluation of the utility of enterprises on the chain, etc., becoming an effective tool for corporate bank loan credit, financing credit, and transaction credit. protection.

First of all, the blockchain can time-stamp all the transaction data in the supply chain and cannot be tampered with at will. Even if the transaction data of a certain node can be tampered with, it cannot cover the sky with one hand, so the area Blockchain solves banks' concerns about corporate information being tampered with. For some small businesses, as long as they have good credit, the possibility of borrowing from banks will be greatly increased.

Secondly, through effective integration, the information between upstream and downstream enterprises recorded in the blockchain can not only provide support for enterprises in production, sales and other links, but also provide downstream enterprises with the ability to analyze customer preferences. , so that targeted services can be developed.

Ⅸ What are the practical applications of blockchain technology

1. Financial field

Blockchain is used in international exchange, letters of credit, stock rights registration and Financial fields such as stock exchanges have potentially huge application value.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields.

Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralization of these fields Characteristics also bring some problems, which can be transformed using blockchain.

4. Digital copyright field

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.

5. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

6. Public Welfare Field

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for social welfare scenarios.
