Describe the application scope of blockchain

3.

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

4. A: blockchain technology has been applied in many fields
I. financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields< Second, the Internet of things and logistics
blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain
Third, public service
blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain
IV. in the field of digital right
through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership< 5. In the field of insurance
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs< 6. In the field of public welfare, the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios.

5. Blockchain application fields:
1. Financial field. Blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment< 2. Internet of things and logistics. Blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

3. Public service. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with< 4. Digital rights. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection. For example, mine labs, a start-up company in New York, developed a metadata protocol based on blockchain. This system called mediachain uses IPFs file system to realize right protection of digital works, mainly for right protection applications of digital pictures

5. Insurance. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized. A typical application case is lenderbot, which was launched by the blockchain enterprise stratumdeloitte and payment service provider lemonway in 2016. It allows people to register customized micro insurance procts through the chat function of Facebook messenger to insure the high value items exchanged between indivials, and the blockchain replaces the third party role in the loan contract< 6. Public welfare. The data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision.

Although the current blockchain technology is still in the initial stage, the advantages of this technology have begun to be reflected. In many fields, blockchain can proce great value, and I believe there will be more landing application scenarios in the future,

blockchain + cross border payment

at present, the mainstream way of cross-border remittance is wire transfer, and its cycle is generally as long as three to five working days. In addition to certain handling charges, intermediary banks will charge certain handling charges, Swift (Global Interbank Financial Telecommunication Association) will also charge a higher fee for the message exchange of its system. In China, a single fee of 150 yuan will be charged for cross-border remittance through the Bank of China

and the use of blockchain technology allows the remitter and the payee to pay and settle directly, eliminating all intermediate costs, so that cross-border payment and settlement can be completed point-to-point quickly. While improving the speed of settlement, it can also achieve all-weather payment, real-time arrival, simple embodiment and no hidden cost
