Blockchain + cross-border payment

p>

The current mainstream cross-border remittance method is wire transfer, and its cycle is generally three to five working days. In addition to the intermediary bank that will charge a certain handling fee, a software called SWIFT (Global Interbank Financial Services) Telecommunications Association) will also charge higher fees for the message exchange carried out by its system. In my country, cross-border remittances through Bank of China will be charged a single fee of 150 yuan.

The use of blockchain technology allows the remitter and payee to pay and settle directly, eliminating all intermediate costs, allowing cross-border payment and settlement to be completed quickly point-to-point, improving In addition to the speed of clearing, it can also achieve round-the-clock payment, real-time arrival, simple implementation and no hidden costs.

❺ In what aspects is the application of blockchain technology reflected?

Blockchain has become well known. So what are the application areas of blockchain?

At present, the most extensive and successful application of blockchain technology is the 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 a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency.

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 market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. 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 digital currency applications, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.

As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. 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.

(1) Blockchain medical care: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to 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 changetransfer, and ensure that the transfer process is credible, auditable and transparent to effectively prevent piracy and other behaviors. 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 is to rely on third parties with credibility. The company makes credit endorsements, but problems such as fraud and deficiencies still exist.

❻ What are the practical applications of blockchain technology

Answer: Practical applications of blockchain technology

1. Financial field

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 fields

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.

❼ Public financing is optimistic about "chain" applications in three major fields in the long term

At the 12th Industry Frontier (Shenzhen) Roundtable Forum, Southern Fund, Rongtong Representatives from many public funds, including the Fund, participated in the discussion.

With policy support, blockchain technology, as a new generation of information technology, is expected to usher in new development opportunities. A public fund source said: "With the gradual implementation of relevant application cases, blockchain has long-term investment opportunities. Specifically, we are optimistic about the three main opportunities of financial services, people's livelihood services, and government affairs scenarios in the long term."

Wide range of applications

Zheng Xiaoxi, fund manager of Southern Asset Management, said that the core problem solved by blockchain technology is the crisis of trust between people, which helps to establish a social mechanism of mutual trust and consensus.

In Zheng Xiaoxi’s view, the application of blockchain technology is divided into three stages: the first stage is applied to the currency field, such as encrypted digital currency, digital payment systems, etc.; the second stage is applied to the contract field, such as Stocks, bonds, credit, asset ownership and smart contracts, etc.; the third stage shouldUsed in government, health, science, culture and art, etc., it helps achieve weak centralization and social autonomy. "Currently, the application of blockchain technology is mainly in the first and second stages."

Ping An Fund also believes that the essence of blockchain lies in decentralized trust mechanisms and smart contracts, or for some Business activities have an impact.

Specifically, in the field of food traceability, blockchain technology can accurately track all aspects of food production to ensure food safety; in the field of supply chain finance, it is convenient for lenders to accurately understand the true identity of borrowers. information to accurately calculate the possibility of lending and predict the bad debt rate. "In the future, as long as trust relationships and commitment fulfillment are involved, blockchain technology can improve efficiency."

According to Lin Qingyuan, fund manager of Rongtong Fund, blockchain technology solves the problem of value transmission and is regarded as It is a big leap in the development of the Internet for more than 20 years. Blockchain technology is a basic technology protocol that is parallel to the underlying protocol of the Internet.

"Only two of the three characteristics of high efficiency, decentralization and security can be achieved, which determines the limitations of the application of blockchain technology." Lin Qingyuan said bluntly that the blockchain structure is A utopian idea to achieve ideal decentralization.

"In new technological innovations and industrial changes, the integrated application of blockchain technology plays an important role." Baoying Fund believes that as an important breakthrough for independent innovation of core technologies, blockchain will clearly focus on direction, increase investment, focus on conquering a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation. "It can be widely used in many fields such as finance, logistics, public services, digital copyright, mutual insurance, etc."

Has long-term investment opportunities

As applications are gradually standardized, areas The development environment of blockchain technology is becoming more and more healthy, and the strategic status of the industry has been greatly improved.

"Blockchain, together with artificial intelligence, quantum information, mobile communications, and the Internet of Things, is a representative of a new generation of technologies." Zheng Xiaoxi said that there are three reasons why blockchain is mentioned again at this time. . From the perspective of policy orientation, the open and transparent technical characteristics of blockchain itself are an important tool for improving social governance capabilities. It has a unique role in solving targeted poverty alleviation, loan difficulties for small and micro enterprises, and opening up data islands; in the direction of science and technology , any technology track should not be ignored. Blockchain technology, as an important part of the next generation of information technology, is gradually being recognized; in terms of regulatory orientation, the development of blockchain in the country has been mixed before, but it has improved after rectification. "At present, the Ministry of Industry and Information Technology has launched two phases of filing, and it is expected to continue to advance."

From the perspective of practical progress, Baoying Fund stated that most of the applications of blockchain technology are still in the process of conceptual exploration and testing. . Zheng Xiaoxi believes that blockchain will be combined with cutting-edge technologies such as 5G, Internet of Things, and artificial intelligence to help promote the current Internet to the second generation of intelligent Internet.

“At present, central banks in various countries areAttaching great importance to the exploration of blockchain technology, it is crucial to master the core technology of blockchain. "Ping An Fund believes that the rational application of blockchain technology with independent intellectual property rights can improve the efficiency of resource allocation in society and reduce social conflicts and frictions.

Regarding investment opportunities in the blockchain track, Ping An Fund He believes that the current blockchain technology is in the application exploration period and gradual realization period, and there will be good application cases in the next 2 to 3 years. “Therefore, it is necessary to lay out long-term investment opportunities. What needs to be done now is to judge the potential of blockchain technology. The possibility of implementing specific application scenarios, evaluating the profit model and core competitiveness, and predicting future growth space. ”

Zheng Xiaoxi said that the three major characteristics of low cost, supervision and easy promotion will lay a solid foundation for the rapid popularization of blockchain across the country and even the world. From the perspective of industry investment opportunities, the main focus is Three main lines: the first is the financial services field, tracking opportunities such as supply chain finance, financial technology, financial security, and blockchain asset hardware storage; the second is the people's livelihood service field, including investment opportunities such as electronic invoices and payments, electronic certification, and copyright services; The third is government affairs-related scenarios, which may have large investment space in the future.

❾ What are the application areas of blockchain?

What are the application areas of blockchain? Introduction to the Blockchain Application Industry
As we all know, blockchain is very popular now. It is a shared distributed database technology. Blockchain technology will have very good results in different industries with its remarkable characteristics. Development prospects, so what are the application areas of blockchain?
Blockchain Applications
1. Digital Currency: At present, the most extensive and successful application of blockchain technology is the 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 a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Since the emergence of Bitcoin, hundreds of digital currencies have appeared one after another, and a relatively large industrial chain ecosystem has been formed around the generation, storage, and transactions of digital currencies. Taking Bitcoin as an example, participating institutions can be mainly divided into four categories: infrastructure, trading platforms, ICO financing services, and comprehensive blockchain services.
2. Financial application: Blockchain has inherent advantages in the financial field. On the Internet, this is determined by the genes of blockchain. From a subjective point of view, financial institutions have the strongest willingness 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 market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. 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 sector, excluding digital currencyApplication, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.
(1) Insurance business: With the development of blockchain technology, information about personal health status, accident records and other information may be uploaded to the blockchain in the future, allowing insurance companies to be more timely and timely 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 tickets: The pain points in this field lie in three risk issues. Operational risk: due to the centralization of the system, once there is a problem with the central server, 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 risks in traditional centralized systems.
(4) Cross-border payment: The pain points in this field are 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 points in this field are the lack of data sharing, information asymmetry between credit information agencies and users; 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 , the 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 agencies to identify the authenticity of various relevant vouchers in the supply chain, resulting in manual reviewIt takes a long time and the financing cost is high. 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.
3. Blockchain + Industry Application:
