Ⅰ What is the popular explanation of blockchain? You must know these five application scenarios of blockchain!

Recently, blockchain has become popular overnight, and everyone around is discussing blockchain.

So, is the blockchain the same as Bitcoin?

In fact, Bitcoin and blockchain are not the same thing.

Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

Bitcoin is just a string of data in a computer. Compared with paper currency, it is also called a "virtual currency". To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

What is blockchain? What are the characteristics of blockchain technology?

Let’s first take a look, why is blockchain called blockchain?

Data is stored piece by piece, and the data stored piece by piece is called a block. Different blocks are linked to the previous block, which is called a blockchain.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes, Lao Wang and Xiao Wang. These blocks are connected to form a blockchain.

Fundamentally, blockchain is a distributed ledger database.

What does distributed ledger mean?

Let’s take a look at the traditional accounting method.

The traditional accounting method is a centralized accounting method. For example, if Lao Wang lent 10,000 yuan to Xiao Wang, if Lao Wang did not tell the world about this money, then this amount would Only Lao Wang knows about the money transactions, Xiao Wang knows, God knows, and Earth knows. This accounting method is a centralized accounting method. This method has a very fatal shortcoming: what should I do if the other party does not acknowledge the account? In fact, in real life, in spontaneous private lending relationships, there is no evidence when the lending relationship occurs, resulting in many cases where the other party does not acknowledge the debt afterwards.

Lao Wang adopted a bookkeeping method that was known to the world from the beginning, which prevented laterYes, this method is a blockchain distributed ledger, which has the characteristics of decentralization. Everyone is the center and everyone can testify to the existence of this transaction.

In addition to the characteristics of decentralization, blockchain also has the characteristics of being immutable. In the blockchain, if the data in any one block changes, even if it only changes a punctuation mark, it will become invalid and needs to be recalculated. Therefore, in the blockchain technology, once a piece of data changes, the cost will be Very big. Unless all nodes in this blockchain have 51% control. Therefore, the blockchain system will be stable and secure.

It’s still Lao Wang and Xiao Wang. If Xiao Wang wants to default on his debt, he can’t tamper with it unless he bribes everyone in the world who knows about the transaction.

Blockchain is also open and transparent.

In blockchain technology, all data is public, which is still the case of Lao Wang and Xiao Wang.

If Xiao Wang does not acknowledge the money, once this news is released, then Xiao Wang’s reputation will be ruined. He can only release new news and wash away the money by paying back the money. Clear your own identity.

Some people say that if the blockchain is so powerful, will my identity information be revealed and there will be no privacy? In fact, the blockchain has the characteristics of anonymity and protects our privacy very well. Unless required by legal regulations, technically speaking, the identity of each block node does not need to be disclosed or verified and can be done anonymously.

What are the applications of blockchain?

The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.

In addition to digital currency, the future applications of Bitcoin are still very wide, and blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.

1. Payment and clearing

The role of the intermediary bank can be abandoned, point-to-point payment can be realized, intermediary fees can be reduced, and fund utilization can be accelerated.

2. Product traceability

For example, if we buy a piece of clothing on a certain website, we can see the past and present life of this piece of clothing.

3. Securities trading

Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.

4. Supply chain

Introduce blockchain technology into the supply chain system, synchronize information within the system, and achieve control over all links.Control, better complete division of labor and collaboration, and facilitate accountability afterwards.

5. Intellectual property rights

With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.

II Application of Blockchain

1. Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of the world's medical institutions will...
2. Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, Covering supply chain management, sharing economy, etc., the IoT application of blockchain technology will become a very important application field.
3. Blockchain + IP copyright & cultural entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition.

Extended information:
1. Current application cases of blockchain
1. Application case 1: Tami Chain is a consortium chain platform based on Super Ledger, which realizes the non-stop application of Chinese state-owned enterprises. On-chain services for investment, financing and M&A transactions of target asset projects. The universal points management system (TamiDou) forms an internal reward mechanism, mobilizes production enthusiasm, and promotes the conversion of rights and data interoperability between various objects in the Tamichain ecosystem. The objects of shared points can be members of the corporate ecosystem such as trading institutions, investors, intermediary service partners, etc. Different issuance mechanisms and circulation mechanisms can also be formulated for different members to achieve positive interactions among blockchain digital points, business goals, and participants. The construction content includes: 1. Blockchain basic platform; 2. Points system; 3. Data circulation platform; 4. Certificate storage system; 5. Other subsystems on the chain. Project address: Enterprise M&A and Financing Information Service Platform_Tamigo
2. Application Case 2: Xuyuan Art Digital Asset Trading Service Platform is a trading platform for art copyrights and a discovery platform for global art values. A truly decentralized high-end service platform for the international art market. Based on the blockchain token, the platform implements an encrypted digital currency based on the world's outstanding artworks to exchange the value of artworks. Functions include copyright certification: artists and creators can perform copyright certification on the platform. Asset tokenization: Art creators divide the artistic copyright into tokens, and investors invest according to their subscription shares and receive income. Usage rights trading: Artists and creators place the rights to use artworks on the chain for transactions, and trigger smart contracts, allowing buyers to obtain the rights to use artworks (including various transactions such as leasing, exhibitions, etc.).

III Application aspects of blockchain

BlockchainThe main application areas include: digital currency, financial asset transaction settlement, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields. Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can beBlockchain smart contracts provide protection.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is collaborating with Nasdaq.Cooperation, realizing the equity transfer of private companies through blockchain

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision, because blockchain technology can ensure information The transparency and unchangeability of the system play a great role in the implementation of transparent government management. There is a certain degree of information opacity in government project bidding, and companies also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with, and can ensure the transparency of information, forming a shared trust among competitors who do not trust each other. And it can arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied in various places

IV How to apply blockchain How to apply blockchain

1. Financial field:
Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration, and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.
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. This field is considered a promising application direction of blockchain.
3. Public service field:
Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. However, the centralized nature of these fields also brings some problems. Blockchain can be used chain to transform. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.
4. Digital copyright field:
Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing the full life cycle management of digital copyright and also serving as a technical guarantee in judicial evidence collection. For example, MineLabs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.
5. Insurance field:
In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often manageManagement and operating costs are higher. Through the application of smart contracts, Can Thanh Orange does not require the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the policy will realize automatic claim settlement. A typical application case is LenderBot, which was launched in 2016 by the blockchain company Stratumn, Deloitte and the payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger to provide insurance services between individuals. The high-value items exchanged are insured, and the blockchain replaces the third-party role in the loan contract.
6. Public welfare field:
The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

IV How to apply blockchain

For blockchain and traditional IT and data technologies, I believe that the future development of blockchain technology must be "integration".

1) Traditional financial IT companies:

Blockchain technology can be quickly adopted by financial IT and insurance companies due to its outstanding technical characteristics of openness, transparency, uniqueness, safety and reliability. Applications in the IT field.

2) Traditional IT sharing companies:

The core capabilities of blockchain are mutual trust and sharing, so it is easy to be fully integrated with the concept of the sharing economy and then applied.

3) Traditional IT technology companies:

Blockchain will become part of the computer cloud services and big data of traditional IT companies. Nowadays, multinational IT companies are making great efforts in security and analysis, and all these services can be built on the basis of blockchain.

4) In addition, blockchain also has great complementary advantages in the field of AI companies. Blockchain is a new type of distributed database technology, so blockchain technology can solve problems in AI applications. Regarding the issue of data credibility, with blockchain technology, AI can focus more on algorithms.

However, I feel that blockchain technology is still in its infancy and needs time to be researched and verified. The final opportunity to defeat the enemy is always reserved for those who are prepared!

VI How to apply blockchain technology and what role it can play

Take buying a house as an example: Buying a house is a complex transaction process, with participants including sellers, buyers, intermediary companies, Housing authorities, banks, appraisal companies, tax bureaus, etc. Throughout the transaction process, all participants must record their own ledgers separately. Checking these ledgers is a very time-consuming and laborious task, and the verification cost is very high. That's why the entire process of buying a home now takes an average of two months.

In addition to being time-consuming and labor-intensive, since there is very little information that can be verified by a single participant, there is a risk of being "cheated from both sides" by the intermediary company, or "sold for more than one house.""Risk. However, blockchain provides a solution: integrating all participants' ledgers into a trustworthy and non-tamperable digital ledger, which can be queried by all participants. In this way, every step in the house purchase process All links are clearly visible, and everyone can conduct transactions with less time and effort.

Bitcoin is the first application of blockchain technology. Bitcoin is operated and managed without any centralized organization. In this case, it has maintained stable operation for many years without any problems. Through this case, everyone has seen the potential of blockchain technology.

In order to prevent single points of failure and system failures, the current financial industry Sexual risks require strict supervision and layers of audits to control risks, which also results in high internal costs. The traditional cross-border settlement method is settled through intermediaries such as SWIFT, so the settlement speed is very slow, but Bitcoin is completely Without the operation of a centralized institution, it has been operating perfectly for many years, not only being able to achieve settlement and clearing in real time, but also not having a single accounting error.

According to a report issued by Santander, Spain’s largest bank The report shows that if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs every year. Such data is enough to illustrate the huge changes that "blockchain" has brought to the traditional financial field. and breakthroughs.

VII What are the application aspects of blockchain technology?

Blockchain has become popular, so what are the application fields of blockchain?

< p>At present, the most extensive and successful application of blockchain technology is digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has high transaction circulation value, and can maintain relatively stable prices by developing hedging financial derivatives as quasi-super-sovereign currencies.

Financial institutions are the most willing to explore blockchain applications and need new technologies to Improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the financial industry has a huge market space, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If If the application of blockchain in the financial field is verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to the application of digital currency, blockchain is also gradually used in cross-border payments, supply chain finance, Insurance, digital bills, asset securitization, bank credit and other fields have begun to be applied.

As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually reflected in other industries. Value. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain" is becoming a reality.< /p>

(1) Blockchain medical care: In the medical field, blockchain can use itselfIts anonymity, decentralization and other features protect patient privacy. Electronic health (EHR), DNA wallet, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.

(2) Blockchain Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things with blockchain technology Application will become a very important application field.

(3) Blockchain IP copyright & cultural entertainment: Since the Internet became popular, digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain has the characteristics of disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors. Blockchain Public Services & Education: In the fields of public services, education, closed-door charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on third parties with credibility. The company makes credit endorsements, but problems such as fraud and deficiencies still exist.

VIII Which fields are blockchain suitable for?

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 because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.

Ⅸ What are the applications of blockchain

Briefly introduce the application of blockchain technology in the financial field

1. Area The application of blockchain technology in the banking industry

The biggest feature of blockchain technology is decentralization, and this feature will reduce a lot of costs for the banking industry.

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, banks have always relied on third parties to realize the transfer of valuable certificates, even ifIt is an electronic bill transaction that also requires cross-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, thus 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 blockchains to ensure that bank customers’ transaction information and transaction records are true and valid and will not be compromised. If it is arbitrarily tampered with, the bank can effectively identify the customer's information, understand all aspects of the customer's situation, identify the customer's abnormal transactions, prevent being deceived by the customer, and can also promptly discover illegal money laundering, fund transfer and other criminal activities, thus reducing the supervision of the bank. cost.

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 through distributed dataDigital registration system automatically completes settlement and liquidation steps. 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, and 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, and the blockchain records Commodity circulation information, etc., can prove the authenticity and reliability of commodities and their circulation, thereby enabling a comprehensive evaluation of the utility of enterprises on the chain, and becoming an effective guarantee for corporate bank loan credit, financing credit, and transaction credit. .

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.

X What are the applications of blockchain in the industry?

Taking 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 is used in finance, games, entertainment and other fieldsThere are also applications.
