1. What industries are blockchain suitable for?

Industries suitable for blockchain include financial industry, copyright protection, traceability and anti-counterfeiting, energy industry, sharing economy, Internet of Things, etc.
my country’s blockchain industry has developed over the past ten years. Basically, a relatively mature industrial chain has been formed. Under the conditions of national policy promotion and increasing demand in downstream application fields, the market scale of my country's blockchain industry continues to develop, with high geographical concentration and obvious industrial cluster effects.
With the increasing maturity of blockchain technology, the blockchain industry is entering the 3.0 stage as a whole, with good performance in finance, logistics, copyright protection and other fields. In order to promote my country's digital construction, accelerate The Digital China process has made a huge contribution.

2. FISCO - Golden Chain Alliance creates a new era of public alliance chain

Public chain, alliance chain (permission chain) and private chain can be said to basically include blockchain technology Three ways to use it. In recent years, the planning, financing, development and ecological construction of the public chain can be said to have been carried out in a noisy manner. Some are real, and there are even more deceptions. It is noisy, noisy, muddy and sandy, and investors' money has really gone in. But not many are online, and the ecological construction of the few public chains that are online is also sparse. There are very few DApps, and the daily activity is even less. In short, not many current public chain projects can or are willing to survive. Ecological construction is even further away.

Private chains are self-built and internally run blockchain architectures of respective companies and institutions. Very little information is disclosed, but I believe that using your own money to do your own things and solve your own problems will not cause any problems. What a big deal.

The development of the alliance chain has always been low-key. Since blockchain technology was recognized by the mainstream economy and society, pragmatic mainstream economic institutions have been solidly carrying out research, development and application for about 4 years. During this period, the backbone of the alliance chain was formed, and another correct path was found for the implementation of blockchain applications and ecological construction. In a certain sense, the alliance chain has passed its infancy and has begun to solidly move towards the "public alliance chain" new era. The alliance chain's naturally strong relationship with mainstream economic industry resources also determines the alliance chain's mainstream status in the application prospects of blockchain technology.

With the dawn of the digital economy era and the popularization of distributed business models, blockchain technology has also been able to give full play to its advantages and become a representative of cutting-edge technology. In 2016, three companies, WeBank, a member of the Golden Link Alliance, Shanghai Wanxiang Blockchain, and Matrix Yuan, a member of Chinaledger, reached a strategic cooperation and jointly committed to exploring blockchain technology, and

The full name of Golden Link Alliance is Financial Blockchain Cooperation Alliance (Shenzhen). It was jointly established on May 31, 2016 by more than 20 financial institutions and technology companies including Shenzhen Financial Technology Association, Shenzhen Qianhai WeBank, and Shenzhen Securities Co., Ltd. non-profit organizationorganize. As an open organization, Financial Institutions that voluntarily abide by the charter and companies that provide technological services to financial institutions can apply to join. So far, members of the Golden Link Alliance include more than 80 institutions in six major industries including banks, funds, securities, insurance, local equity exchanges, and technology companies.

On November 26, 2016, Golden Link Alliance released the "Financial Distributed Ledger Proposal", proposing five major principles such as legal compliance, traceability, security, privacy protection, and business orientation, as well as a value alliance , autonomous and controllable, safe and trustworthy, efficient and available, business feasible, flexible configuration, intelligent supervision and other seven propositions.

Purpose: Integrate and coordinate financial blockchain technology research resources, form a synergy and coordination mechanism for financial blockchain technology research and application research, and improve the research and development capabilities of member units in the field of blockchain technology. Explore, develop, and implement financial alliance blockchain suitable for financial institutions, as well as application scenarios based on this.

The General Assembly of the Golden Chain Alliance is the highest authority; the permanent body of the General Assembly is the Presidium, which leads the alliance to carry out daily work during the intersessions of the General Assembly and is responsible to the General Assembly; the Presidium has a technical committee (chaired by Application project work), Standards Technical Working Committee (presides over the establishment, formulation, review and release of standards), Advisory Committee (organizes external experts to participate in technical and standards discussions).

Jinlianmeng has established research directions in the fields of credit, equity, points, insurance, bills, cloud services, digital assets, financial product issuance and trading, and some of the projects have now been implemented or products have been launched. prototype.

The FISCO BCOS underlying blockchain platform is jointly built by the FISCO open source working group. Members of the working group include Beyondsoft, Huawei, Shenzhen Stock Exchange, Digital China, Sifang Inextron, Tencent, WeBank and Yuexiu Jinke and other members of the Golden Link Alliance, aiming to create a secure and controllable blockchain suitable for the financial field. The underlying platform of the chain.

Financial services are one of the earliest application areas of blockchain. Blockchain technology brings advantages such as safety and reliability, simplified processes, cost savings, reduced operational risks, and increased trust, and has the potential to reconstruct and sublimate the original financial industry infrastructure. The financial industry focuses on multi-party reciprocal cooperation and has strong supervision and high-level security requirements, which require node access and authority management. Therefore, the technical direction of the alliance chain has become the main choice for the financial industry.

At present, my country's financial industry is opening up to the outside world with unprecedented intensity, and the pace of financial innovation is also accelerating. Therefore, how to effectively balance the relationship between open innovation and risk prevention and firmly maintain the bottom line of no systemic risks is an important issue for the industry. challenges that urgently need to be addressed.

From the perspective of financial IT infrastructure, there are still some shortcomings and pain points in operational risks, moral hazards, credit risks, information protection risks, etc.

First, financial IT system data may still be tampered with, forged, or have consistency differences.

Second, the infrastructure structures and business processes of different financial institutions are different, and even still involve many manual processes, which greatly increases operating costs and is also prone to operational risks and ethics. risk.

Third, financial business and financial cooperation may involve multiple participants or intermediaries, which can easily increase trust costs and friction costs. There are also certain issues of mutual trust, collaboration or cooperation reciprocity.

Fourth, financial business is often highly complex, and it is easy to miss records of all business elements. Sometimes it is difficult to trace the entire business process, and it cannot meet the needs of supervision and auditing.

Fifth, the data between different financial institutions are relatively independent, making it difficult to achieve safe and efficient interaction, resulting in high costs for repeated KYC, anti-money laundering, and anti-fraud, and also indirectly causing the loss of user data. Risk of being leaked by certain intermediaries.

Sixth, the availability and adaptability of centralized IT infrastructure are weak, and distributed technologies need to be used to improve robustness or adaptability.

As a combined infrastructure solution, blockchain technology can in principle respond to the needs of the financial industry. However, because the requirements of the financial industry are more diverse and strict, as a financial version of the blockchain solution, it needs to be based on the blockchain technology of the universal industry and according to the special business needs of financial institutions, existing technical levels, and laws and regulations. Requirements or conditions in other aspects shall be comprehensively considered from multiple dimensions such as business suitability, performance, security, policy, technical feasibility, operation and maintenance and governance, and cost.

First, the appropriateness of the business scenario. Not all financial business scenarios require the use of blockchain technology. Generally speaking, when it comes to scenarios involving multi-party participation and peer-to-peer cooperation, the traditional centralized system architecture is often difficult to meet the needs, so you can consider using blockchain technology. This will increase multi-party mutual trust, improve business operation efficiency, and reduce business operation costs and friction costs.

Second, the performance of the blockchain system. Financial business often has characteristics such as massive transactions, high-frequency transactions, and timely confirmation. Therefore, the blockchain open source platform in the financial industry needs to analyze the business volume, potential business growth scale, and potential business growth scale that the blockchain system needs to support based on the current business scale of financial institutions. Technical performance index requirements such as concurrent business volume and response time. Since blockchain platforms using different technical modules, such as different consensus mechanisms, have greatly different performance support, it needs to be evaluated based on business performance requirements and blockchain performance efficiency indicators.

Third, the security of the blockchain system. Blockchain can ensure the credibility of recorded data from a technical level and prevent data from being tampered with, forged and other risks. In addition, in terms of data sensitivity and security, it is necessary to evaluate the content encryption strength of the on-chain data, as well as access control, etc. Financial institutions need to choose mature, appropriate, and secure encryption algorithms based on the specific security requirements of their business.

Fourth, policy compliance. Blockchain is a set of technical solutions that, with reasonable design, can provide good support for existing businesses or complement existing centralized systems. However, when financial institutions use blockchain to conduct business, they must implement it within the country's existing regulatory requirements and legal framework.

Fifth, technical feasibility. Blockchain technology has already been implemented in some financial scenarios, but it is still an emerging technology. It is necessary to fully evaluate the fit of the technology with specific businesses and its advantages and disadvantages compared with traditional systems before finally choosing the appropriate area. Demonstration and trial operation of the blockchain platform.

Sixth, operation and maintenance and governance capabilities. Since there are differences in operations and management between blockchain-based businesses and traditional centralized systems, and the continuous governance requirements of financial businesses are extremely high, corresponding planning and adjustments are required to evaluate the feasibility and sustainability of the new governance structure. , evaluate the impact of version iterations and the official launch of the system, monitor the operation of the blockchain system in real time, and ensure business controllability and financial environment stability.

Seventh, costs are controllable and economically feasible. Blockchain applications use technical features to solve specific problems in actual business. Applications that effectively solve pain point problems can bring great benefits to financial businesses, and the value of the application itself can also be revealed; on the contrary, if it cannot solve important problems in the industry , you need to face a trade-off between costs and benefits.

If a safe and reliable underlying financial blockchain platform can be built to meet the special needs of the financial industry, blockchain technology will be of great use in the financial industry.

For example, from the perspective of banking institutions, the key exploration directions are generally to apply blockchain technology to reduce clearing and settlement costs, improve middle and back-office operational efficiency, improve process automation, and reduce operating costs. In addition, in cross-border financial scenarios, blockchain can help realize ledger sharing among cross-border financial institutions, reduce reconciliation and settlement costs and dispute friction costs between cooperative banks, thereby improving the processing speed of cross-border business. and efficiency.

From the perspective of non-bank financial institutions, blockchain can be used to improve the authority of rights registration and information storage, reduce counterparty risks, solve data tracking and information anti-counterfeiting issues, and reduce audits. operating costs, etc.

From the perspective of financial regulators, blockchain provides regulators with consistent and easily auditable data.Chain-based data analysis can supervise financial businesses faster and more accurately than traditional audit processes. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly strengthen anti-money laundering efforts.

Designed an efficient, reliable, message communication protocol based on the blockchain network, referred to as AMOP (Advanced Messenger On-chain Protocol), focusing on the following functions:

 Based on the blockchain network, it supports cross-bank and point-to-point real-time message communication;

 Provides standardized interfaces for the interaction between off-chain systems and blockchain;
< br />  The blockchain system can actively call the business interface of the off-chain system;

The technical characteristics of this protocol are:

 In the point-to-point blockchain network topology , plan node communication paths to ensure message reachability;

 Can quickly sense node abnormalities in the blockchain network and automatically switch paths to resend messages;

 In communication Encryption technology is used in the process to ensure privacy at the communication layer.

Designed the contract naming service CNS (Contract Name Service). The design goal of CNS is to name the correspondence between the business layer and smart contracts, so that the business layer no longer cares about the relevant contract addresses. Similar to DNS on the Internet, the use of domain names makes it easier for users to remember how to access a website, and also gives the website great flexibility in terms of clustering, migration and expansion.

The most high-profile champion project - ODRChain, is based on the FISCO BCOS underlying platform and uses blockchain technology to solve the pain points of traditional judicial processing of online disputes, such as the difficulty in verifying the authenticity of electronic data and the inability to digest a large and rapidly backlog of case disputes.

At present, ODRChain has shortened the time it takes for customers to go from clicking "one-click arbitration" to receiving the arbitration award, from the traditional arbitration process that lasted several months to about 7 days. , and the arbitration fees that originally cost tens of thousands of dollars have been reduced to a few hundred yuan. As of December 2018, ODRChain has completed the deposit of over 10 million contracts, involving hundreds of billions of funds.

First prize: JustSign - a white-box cryptographic algorithm that turns a mobile phone into a USB shield

The project that grabs the first prize in the competition - JustSign, is based on FISCO BOCS It is an electronic contract signing and certificate storage system. Its original JustKey white-box cryptographic algorithm realizes "mobile phone as USB shield", which solves the problem of limited compatibility of traditional CA, inability to protect key security on the mobile terminal, and vulnerability to attacks in centralized data storage. question.

Expert reviewers commented that electronic contracts involve complex legal relationships and ownership of interests, and it has long been difficult to achieve a balance between security, integrity and portability. The team’s original white-box cryptographic algorithm is really conducive to improving security in blockchain certificate storage scenarios.

Second Prize: Internet of Things Trusted Interconnection Solution - The Picture of Smart Life Looks Like This

The Internet of Things Trusted Interconnection Solution competed by Sichuan Changhong Security Laboratory depicts Come up with a smart home blueprint that requires almost no extra worry on your part. When analyzing the blockchain technology behind it, a team representative said that an inter-enterprise cooperation alliance is established based on the alliance chain to open up the interconnection and mutual trust of IoT devices between different manufacturers, and based on insights into typical business scenarios of smart life, through smart contracts Implement smart terminal registration, scene rules, trust rules and linkage rules.

The expert judges of the competition believe that this project has practical hardware and scenarios in the field of Internet of Things, and is expected to further promote distributed AI assistants, resource sharing, and life cycleApplication scenarios such as futures management and multi-channel payment have been implemented, truly ushering in smart life.

Among the projects that won the third prize in the competition, they accurately targeted the characteristics of blockchain in terms of security and efficiency improvement, and provided practical solutions for the industries they represented. Tsinghua University The team of teachers and students found a new way to develop cross-layer full-stack blockchain security detection technology to protect other blockchain applications comprehensively, and its technical strength was highly praised by the judges.

The third prize winners were the trusted electronic certificate platform of Shenzhen E-Commerce Security Certificate Management Co., Ltd., the real estate registration platform of Wuhan Liandong Times Technology Co., Ltd., and Shandong Guanhai Data Technology Co., Ltd. The company's Rongcheng blockchain service platform, the livestock industry blockchain traceability of Quanliantong Co., Ltd., the tourism finance alliance platform of Shenzhen Youxun Information Technology Co., Ltd., and the copyright safe deposit box of Beijing FamilyMart Technology Development Co., Ltd.

Shanghai Jiuyaojiu Information Technology Co., Ltd.’s first-responder mutual aid first aid, “Yongteng Group My Innovate”’s HaveFund, Qianhai Life Insurance Co., Ltd.’s blockchain policy management, “Huazhong Technology The University's Guanshankou Hulu Brothers' Book Enjoying Campus and the Cloud Block project team's "Yun Block" account system also won the Outstanding Social Value Award, Outstanding Business Design Award, Outstanding User Value Award, Outstanding Creativity Award, and Outstanding Application Integration Award respectively.

Ma Zhitao, chairman of the Golden Alliance Technical Committee, elaborated on the concept of the “public alliance chain”. He believes that the alliance chain should achieve self-sublimation and should be able to evolve into an ecosystem that provides services to the public, that is, a "public alliance chain."

Different from the public chain project’s idea of ​​“coming up with a plan first, raising funds, vigorously promoting it, raising the price, and finally investing in development”, the alliance chain project adheres to the idea of ​​“investing in development first with its own funds” , go to the production environment to verify, accumulate real customers and users, run steady trials and errors, and finally carry out promotion and publicity.” However, due to the focus on practical implementation and focusing on real applications, there is a lack of publicity, and it has no choice but to fall into a passive situation of "many people have implemented it, but few people have praised it". Golden Chain Alliance hopes that through this competition, the project team of the alliance chain will come to the stage to show their results, enhance the influence of the alliance chain, and let the public know more about the real application implementation and sustainable development of the alliance chain project.

3. What is the earliest application of blockchain?

The first application is Bitcoin. Bitcoin is the first application of blockchain technology and is also the most successful so far. Applications. Blockchain is a term in the field of information technology. Essentially, it is a shared database. The data or information stored therein has the characteristics of "unforgeable", "full traceability", "traceable", "open and transparent", and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation forIt has a solid foundation of "trust" and created a reliable "cooperation" mechanism with broad application prospects.
1. Blockchain itself is also an Internet protocol, so its basis is data. If there is no structured data in a scenario, or the cost of the data structure is high, you must consider whether it is suitable for a blockchain project. There are several so-called precision poverty alleviation blockchain projects, including supply chain traceability from seeds to tables, fertilizer testing, etc. How is the data entered? Do you have to rely on people to test one by one to enter? Do you track the amount of fertilizer from a detector buried in the earth?
2. There is a strong demand to confirm the authenticity of information in existing scenarios, whether the cost is high or low. Blockchain is essentially a value network, that is, data rights confirmation or authenticity confirmation. Then, whether there are strong authenticity confirmation requirements in the scenario to be applied becomes a necessary factor. For example, for a learning chain project, student evaluations and class status are tracked through blockchain. Is it necessary to use blockchain to address the authenticity of this data? Is blockchain more efficient or WeChat more convenient for word-of-mouth communication in the education market? Do I need to let others know the authenticity of my evaluation of the teacher? Is there a strong need for consensus in the existing scenario, recorded through distributed nodes? Blockchain records information through distributed ledgers and broadcasts it throughout the network, achieving large-scale network-wide consensus while ensuring data unification. So, is it necessary for many projects to adopt large-scale consensus? There is no necessary network-wide consensus. Is it hype or money? There are different opinions.
3. A project called an all-Japanese team but with only a Chinese version of the white paper claims to rent and buy houses in Japan through blockchain, which is done on a share basis, with reference to the ABS model. It claims to enable home sales and rent sharing through tokens. The number of tokens is certain, but in the future there will be more and more houses, and the rent will be higher and higher, so it will become more and more valuable. To put it bluntly, it is an equity crowdfunding project.
4. Whether there is a network effect in the application scenario and whether it conforms to the two-sided market model. The following network effect or two-sided market model theory refers to whether a project can play a positive role in improving the overall project as the number of users continues to increase. . The core value of the project is the user's own network connection. Blockchain itself is a network protocol. Of course, without network effects, that's nonsense. A real-life example is an e-commerce platform. The more consumers there are on the platform, the more merchants there will be. The two-party model continues to promote and promote the healthy development of e-commerce platforms, while e-commerce companies manage both sides of the platform through payment methods such as Alipay to maintain the normal operation of the network.

4. What are the applications in the blockchain field?

Blockchain application fields:
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 to be a promising application direction of blockchain.

3. Public service field. Blockchain is closely related to people's production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain. 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 full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, Mine Labs, 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 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. 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 and exchange between individuals. high-value items are insured, and blockchain replaces the role of a third party in the loan contract.

6. Public welfare field. The data stored on the blockchain is highly reliable and cannot be tampered with, making it 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.

5. In which industries is blockchain technology mainly used?

Blockchain technology is the underlying technology of Bitcoin. In the early days, not many people paid attention to the underlying technology of Bitcoin. technology. But when Bitcoin is operated and managed without any centralized organization,It has been running very stably for many years without any problems. Therefore, many people have noticed that the underlying technology may have a large mechanism, and it may not only be used in Bitcoin, but may be applied in many fields. So the Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology. So from a certain perspective, Bitcoin can be seen as the first application of blockchain, and blockchain is more similar to underlying technologies such as TCP/IP, which will expand to more and more industries in the future.
The main advantages of blockchain are that it does not require intermediary participation, the process is efficient and transparent, the cost is very low, and the data is highly secure. Therefore, any industry that has needs in any of these three areas has the opportunity to use blockchain technology. For example
1. Banking 2. Payments and transfers 3. Cybersecurity 4. Academic records 5. Voting 6. Car rental and sales 7. Network and Internet of Things 8. Forecasting 9. Online music 10. Ridesharing 11. Stocks Trading 12. Real estate 13. Insurance 14. Healthcare 15. Supply chain management 16. Cloud storage 17. Energy management 18. Sports management 19. Gift cards and customer loyalty programs 20. Government and public welfare

6 . In which fields is blockchain suitable for application?

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.

7. What are the main application areas of blockchain technology?

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.

8. What is blockchain and what are its applications?

I have seen your question. So, what are the applications of blockchain? ? The editor will answer it for you below.

Answer: Bitcoin is the first specific application of blockchain. It was proposed in a paper in 2008 by a person or group of people. Bitcoin uses the blockchain to digitally send bitcoins, as BitCoin is known, without the intervention of a third-party middleman.

But Bitcoin is not the only application of blockchain, as follows:

1. Financial field: Applying blockchain technology to the financial industry can eliminate the need for third-party intermediaries. links to achieve direct point-to-point docking, thereby quickly completing transaction payments while greatly reducing costs.

2. Internet of Things and logistics fields: Blockchain can also be naturally combined in the fields of Internet of Things and logistics. 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 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. It can be used to distinguish Blockchain to transform.

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

< p>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 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.

The above is for your reference only, I hope you can adopt it, thank you!

9. Blockchain technologyIn what fields will it be applied in the future?

Anti-counterfeiting traceability, openness, transparency, and non-tampering, giving each "genuine product" a unique mark, allowing buyers to trace the trace from the factory to the consumer. All circulation links (just as express delivery can check all processes now).
