4. Tourism instry: triporg travel is a blockchain tourism service application, which can provide people with reservation services such as train tickets.

5.

The so-called blockchain technology, also known as the distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records

blockchain application:

1. Financial sector: mainly to rece transaction costs and Inter Organizational transaction risks. Blockchain applications in this field will mature as soon as possible, and banks and financial trading institutions will be the main promoters

financial blockchain

since the beginning of human society, financial transaction is an indispensable economic activity. The different roles and contents of transaction reflect different proction relations. Through the transaction, we can optimize the social efficiency and realize the maximization of value. The development of human society is inseparable from the evolution of transaction forms. It can be seen how important transaction is in human society. The essence of transaction is to exchange the ownership of value. Now, in order to complete the transaction (such as the ownership of houses and vehicles), some intermediate links are often needed, especially the role of intermediary guarantee. This is because there is often insufficient trust between the two sides of the transaction, it is not easy to confirm the ownership of value, and often the value of each other can not be directly exchanged. Reasonable intermediary guarantee ensures the normal operation of the transaction and improves the efficiency of economic activities. However, the existing third-party intermediary mechanism often has some shortcomings, such as high cost, long time cycle, complex process and error prone. Because of these, financial services have become one of the hottest application areas of blockchain. Blockchain technology can provide effective and reliable ownership proof and strong intermediary guarantee mechanism for financial services. Financial services include currency, securities, insurance, donation and so on

Credit reference and ownership management: This is the dream of large social platforms and insurance companies, but there is still a lack of sufficient data sources, reliable platform support and effective data analysis and management. The threshold of entrepreneurship in this field is very high, which needs top-down promotion. Because anything that needs to deal with the government has never been very good and will be carried out immediately

credit reference management is a huge potential market, which is said to exceed 100 billion scale (Ping An Securities report, Wells Fargo report), and it is also one of the most promising directions of big data application. At present, a large number of effective data related to credit investigation are mainly concentrated in the hands of a few institutions. Because these data are too sensitive, and are the lifeblood of business, they are often closely protected, thus forming a high threshold of the instry. Although a large number of Internet enterprises (the most successful one should be Facebook) have tried to obtain massive user information from various dimensions, there are still some problems in these data from the perspective of credit reference

• Insufficient data: the larger the amount of data, the higher the value can be obtained, and there is a lower limit for the effective value generated by data. The amount of data below the lower limit can not proce effective value

• Poor relevance: the most core data is often the most sensitive. In today's highly sensitive privacy era, users do not want to expose too much data to third parties, so there are few effective components in the data obtained by enterprises

• Lack of timeliness: the user data that enterprises can obtain from the public is often outdated, and even has false information, which seriously interferes with the credibility of relevant analysis

and blockchain has the characteristics of natural tampering and non repudiation. At the same time, blockchain may provide unprecedented scale highly relevant data, which can be accurately located in time and space and strictly associated with users. Therefore, providing data based on blockchain for credit management will greatly improve the accuracy of credit evaluation and rece the cost of evaluation. In addition, unlike the traditional manual audit, blockchain technology relies entirely on mathematical results, and the credit mechanism based on blockchain will naturally be stable and neutral. IDG, Tencent, Ernst & young, and PwC have all invested in or entered the field of credit information management based on blockchain, especially the application scenarios related to insurance and mutual aid economy

Resource sharing: companies represented by airbnb will welcome this kind of application, which will greatly rece the management cost. The threshold of entrepreneurship in this field is low, the theme is concentrated, and it will be popular with investment

in the era of big data, value comes from data mining. The more data dimensions, the larger the volume, the higher the potential value. For a long time, the headache is how to evaluate the value of data, how to use data for exchange and transaction, and how to avoid valuable data leaking out without permission. Blockchain technology provides the potential to solve these problems. By using the unified ledger composed of blockchain, the flow of data among multiple parties will be tracked and managed in real time, and the management cost of data sharing process can be effectively reced through the control of access rights

4. Investment management: both public and private funds can apply blockchain technology to rece management costs and control risks. Although there is a trial like Dao, we are cautious that the demand in this field is not mature. However, Xiaoyao has found that China's major start-ups have begun to test the water in this field, hoping for a major breakthrough

in international trade activities, buyers and sellers may not trust each other. Therefore, the two banks need to act as the guarantors of the buyer and the seller, to collect and deliver documents on behalf of the buyer, and to replace commercial credit with bank credit. Blockchain can provide a common account book for L / C transaction participants, allowing banks and other participants to have confirmed common transaction records and perform accordingly, thus recing risks and costs. With Dao (decentralized autonomous organization) as the representative of crowdfunding management, Dao has set the highest financing record in history, more than 160 million US dollars

5. Internet of things and supply chain: Internet of things is a very suitable field, and there will be a large number of applications in the short term, especially in specific scenarios such as leasing and logistics. However, the development limitations of the Internet of things will lead to the difficulty of large-scale application in the short term

the supply chain instry often involves many entities, including logistics, capital flow, information flow, etc. there are a lot of complex cooperation and communication between these entities. Under the traditional mode, different entities keep their own supply chain information, which is seriously lack of transparency, resulting in higher time cost and money cost, and it is difficult to trace and deal with problems (false claim, counterfeit goods, etc.). Through the blockchain, all parties can obtain a transparent and reliable unified information platform, which can view the status in real time, rece the logistics cost, and trace the whole process of proction and transportation of goods, so as to improve the efficiency of supply chain management. When disputes arise, the proof and tracing become clearer and easier. This field is considered as a promising application direction of blockchain. IBM has continuously invested in the research and development of the Internet of things for decades, and is currently exploring the use of blockchain technology to rece the cost of Internet of things applications

blockchain is applied only after it has technology, such as Huixin cloud platform: only when it has platform can proct managers enter the platform for development, so technology and application should progress together

the application of blockchain technology is different in the field of instry, and the functions and effects are also different. Let's take the field of credit system for example. Because the leakage of personal information will cause great harm to the informants, which makes them suffer from conservative harassment. What's more terrible is personal information leakage, which is usually accompanied by tens of thousands of personal information being stolen, illegally sold, and even using the formal data trading institutions to steal data

with the rise of blockchain technology, the encryption of blockchain technology can provide solutions for the protection of personal information. Blockchain technology can store personal information in a distributed way to avoid the security risks faced by a single server

and as one of the most ice breakers of blockchain technology research, jinwowo network technology has concted in-depth research and Application on blockchain technology. Jinwowo's big data service based on blockchain can eliminate illegal data reselling and reestablish data circulation rules from four aspects of data storage, data analysis, data tracking and data security

6. 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.

7. This is generally to okex, which is relatively large in China. The real-time market view and transaction operation are also simple.

8. Triporg travel: a blockchain + tourism service platform, which can provide people with travel services such as train tickets.
