Application of blockchain in customs

1. Xu Mingxing is optimistic about the application of blockchain in cross-border payment. Xu Mingxing thinks that blockchain technology will solve many problems in cross-border payment. Traditional cross-border payment needs to go through a number of financial institutions, such as remittance bank, central bank, agent bank, payee bank and so on. To solve cross-border payment based on blockchain technology will save any third-party intermediary link, achieve transaction settlement, and can complete payment very quickly.

In Internet cases, electronic evidence has become a difficult problem in Internet trials because it is difficult to store evidence, collect evidence and notarize. By using blockchain technology, easyprovision can solve the whole link trustworthiness problems of electronic evidence, such as generation, storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the data's trustworthiness and security; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection

easy preservation since 2014, we have been deeply engaged in the R & D and application innovation of the underlying technology of blockchain . By expanding the judicial service channels, we have successfully taken the notary office, judicial authentication center, Internet court, Arbitration Commission, right protection center and other authoritative institutions as the important nodes of the preservation chain, so that electronic data can be saved from the aspects of generation, certificate storage, right protection To the final use, the relevant judicial institutions do synchronous supervision and notarization to enhance the credibility of the blockchain certificate data

What are the applications of blockchain in tourism? What problems can be solved

in the tourism instry, big data maturity, bundling and price increase, and information opacity have become the pain points of the current instry. When Ctrip becomes a channel brand and a dominant company, the so-called decentralization gives other similar companies the opportunity to decentralize the channels

at present, many technology start-ups are focusing on the technology of blockchain, because it will subvert many instries, including banking, health care, ecation and tourism. In fact, blockchain startups received about $1.8 billion in investment in 2017

blockchain in the tourism instry

I believe that everyone who goes out to travel will encounter some inconvenient things more or less. Even if they have made full preparations in the early stage, there will still be some other things that will affect the whole travel experience and mood. For example, long lines of security checks, identification ready, and being asked to give up a seat voluntarily e to overbooking

Secondly, there will be fraud, which is very important. The annual loss of travel agencies is as high as 0.44%, and 4% of the plane bookings are rejected e to fraud. All of these problems will cost the tourism instry 4.8 billion dollars every year

and blockchain can solve these problems well. The following are the application cases of blockchain in tourism

According to statistics, up to 40 million travel documents have been recorded as lost or stolen in recent years. However, through biometrics and blockchain, identity and travel files can be recorded and stored permanently, which can be accessed with a single click. We don't have to print multiple documents for multiple checkpoints on the trip. Credit card information can also be easily stored. Airplanes, hotels and passports can streamline travelers' equipment, and government agencies can handle tourists more safely

2. Smart contract

blockchain has been used to consolidate the contract between enterprises, and neither party can change the terms. In the tourism instry, there is a huge space for smart contracts. Travelers and travel agents will record all transactions in one block; Loyalty programs and tourist points can be stored in blocks; The commission agreement among airlines, hotels and booking agents will also clearly distinguish who gets the fee and when; The company agreement signed with the travel agency can be preserved forever without doubt or hidden expenses

3. Avoiding fraud

as far as I know, there were about 55 million consumers booking third-party platforms that they thought belonged to hotels last year. In fact, these websites were operated by fraudsters. It not only caused the direct loss of consumers, but also affected the reputation of the hotel concerned

if it is applied to blockchain technology, it will effectively solve the above problems and help consumers verify ownership. In addition, with the characteristics of storing documents and identities in block form, travel agencies do not need to manually check whether these reservations are marked as potential fraud. Tourist information can be safely accessed through the blockchain, and the loss caused by fraud will be significantly reced

4. Overbooking

this is an old headache for tourists who may be kicked off the plane because no one is willing to give up their seats. The government is even taking regulatory measures to punish airlines for such acts. Through the blockchain, passengers will have higher security, their reservations will be stored in a block safely, and airlines will be forced to give up the practice of overbooking

in addition, tourism involves various service instries, and there are many different consumption points plans in the process of travel. It's just that all kinds of scoring systems are complicated and isolated from each other, and customers don't know the details very well. This not only affects the interests of customers, but also brings trouble to tourism companies. If we use the blockchain technology to unify these points plans into the shared ledger, and use a wallet to manage points, we may be able to solve these long-standing problems

4. 1. What is blockchain? In a word
A: blockchain is an encrypted database chain, that is, the transaction data in multiple timestamps / events are encrypted and linked together, and the data can not be tampered with or shared
2. Performance and logic:
A. external operation forms: bank deposit and withdrawal, remittance, account in and out, shopping, currency issuance, capital transaction, etc
B. internal logic processing (software program): after human operation, the data will be encrypted first and then stored in the database. After the program, the data will be divided into regions, such as the data in the event and time stamp will be classified and put together into a region. Multiple events and data in timestamps are associated to form a blockchain. The encrypted data can be shared, but not tampered with
C. forms of sharing: querying personal information, auditing, etc. Query permission / sharing permission: different permissions can query different data. For example, the bank can query the information of all people, and the indivial can only query the indivial
3. Most of the examples are different, but the logic processing ideas are the same, but the implementation methods and operations are different
4. Blockchain: it has the characteristics of encrypted data, tamperable data and shared data
5. Blockchain Technology: the technology of encrypting, partitioning and sharing data with editing programs
there are suggestions for guidance
application fields: finance, it, commodity sales, online shopping, etc.

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

in the field of 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

in the field of public service

blockchain is closely related to people's proction and life in the fields of public management, energy, transportation, etc., 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

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. 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

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. 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

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
