① Application aspects of blockchain

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, digital government affairs, certificate deposit and anti-counterfeiting data services, etc. field. 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 canIn order to allow each device on the Internet of Things to operate independently, the information generated by the entire network can be guaranteed through smart contracts on the blockchain.

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.Solution At the same time, blockchain startup Chain is cooperating with Nasdaq to realize 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. Since blockchain technology can ensure the transparency and immutability of information, it plays 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 everywhere

② What are the applications of blockchain technology in the Internet of Things

The main applications of blockchain in the Internet of Things It can solve the following problems: solve security risks, protect user privacy, and reduce the operating costs of the Internet of Things.
In fact, there are many specific applications, but they are all in the process of development and research and development. It can be said that blockchain technology is still not mature. Among many companies, Yingtang Zhongchuang has developed more applications of blockchain technology, which has a certain impact on the future development of the Internet of Things.

③ How to apply blockchain How to apply blockchain

1. Financial field:

Blockchain in international exchange, letters of credit, equity Financial fields such as registration and stock exchanges have potentially huge application value. 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 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. 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, but the centralized characteristics of these fields are also It has brought about some problems that can be transformed using 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, prove the existence of text, video, audio and other works, and ensure the ownership of works. Authenticity and uniqueness. 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, 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 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 blockchain companies Stratumn, Deloitte and payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger, providing 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.

④ The role of blockchain in the field of Internet of Things

To reduce operating costs, blockchain technology focuses on transmitting data through point-to-point direct connection rather than through central processing device. To reduce security risks, the core problem of IoT security lies in the lack of original mutual trust mechanism between devices. Efficient and intelligent network operation mechanism. Since the blockchain has decentralization and consensus mechanism, on the Internet of Things, cross-system data transmission will be transferred from the upper layer to the underlying blockchain.
The combination of blockchain technology and the Internet of Things can eliminate the audit and certification links between nodes, directly build a communication bridge for multiple parties, and improve network operation efficiency. At the same time, the decentralized consensus mechanism based on blockchain can also ensure the security and privacy of the Internet of Things and facilitate the transmission of real information. In view of this, blockchain and the Internet of Things will truly come together and play the strongest voice of the Internet of Everything.
Hongqiao Hi-Tech’s blockchain industry-specific application design uses the integrity and correlation of trusted transaction data to form a closed-loop self-certification capability for data on the chain. for verificationAuthenticity of digital documents and transaction records, as well as tracking the provenance of products and merchandise throughout the supply chain. This data proving product authenticity and origin is generally used by businesses and financial institutions in the assessment and processing of credit and loans.

⑤ 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.

⑦ What fields can blockchain be applied to?

Financial applications: Blockchain has inherent advantages in the financial field. On the Internet, this is the genetic decision of blockchain. of.
(1) Insurance business: With the development of blockchain technology, in the future, personal health status, accident records and other information may be uploaded to the blockchain, allowing insurance companies to be more timely and accurate when customers apply for insurance. Accurately obtain risk information to reduce underwriting costs and improve efficiency. The shared and transparent characteristics of the blockchain reduce information asymmetry and the risk of adverse selection; while its historical traceability characteristics are conducive to reducing moral hazard, thereby reducing the difficulty and cost of insurance management.
(2) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue.
(3) Digital bills: The pain points in this field lie in three risk issues. Operational risk, due to the centralization of the system, once the central server has a problem, the entire market will be paralyzed; market risk, according to statistics, in 2016, there were seven risk events involving hundreds of millions of dollars, involving multiple banks; moral hazard , there are incidents such as "one ticket selling more" and false commercial bills in the market. Blockchain's disintermediation, system stability, consensus mechanism, and non-tampering characteristics reduce operational risks, market risks, and moral hazards in traditional centralized systems (4) Cross-border payments: The pain point in this field is the long payment cycle , high fees and low transaction transparency. The third-party payment company is the center to complete the accounting, settlement and liquidation in the payment process, and the payment cycle is long. For example, the payment cycle for cross-border payments is more than three days, and the cost is high. The blockchain is deintermediated, transactions are open, transparent and cannot be tampered with. No third-party payment institutions are involved, which shortens the payment cycle, reduces fees and increases transaction transparency.
(5) Credit information management: The pain point in this field is the lack of data sharing, credit information agencies and user informationAsymmetry; formal market-oriented data collection channels are limited, and the battle for data sources consumes a lot of costs; data privacy protection issues are prominent, and traditional technical architecture is difficult to meet new requirements, etc. In the field of credit reporting, blockchain has the characteristics of decentralization, trustlessness, timestamps, asymmetric encryption and smart contracts. At the technical level, it ensures that limited and controllable credit can be achieved on the basis of effectively protecting data privacy. Data sharing and verification.
(6) Supply chain finance: The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs. The blockchain's deintermediation, consensus mechanism, and non-tampering characteristics eliminate the need for third-party credit enhancement agencies to verify the authenticity of various relevant certificates in the supply chain, reducing financing costs and shortening the financing cycle.
(7) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue. Blockchain's deintermediation, consensus mechanism, and non-tampering characteristics increase data flow efficiency, reduce costs, monitor the true status of assets in real time, and ensure the trust of all parties in the transaction chain in the underlying assets.
Applications:
(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 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 application of blockchain technology will become a very important application field.
(3) Blockchain + IP Copyright & Culture and 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. 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.
(4) Blockchain + Public Services & Education: In the fields of public services, education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method relies on Credible third parties provide credit endorsement, but problems such as fraud and deficiencies still exist. Blockchain technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in terms of certificate storage, tracking, association, and backtracking.
