The influence of blockchain technology on business information

1. Absrtact: blockchain technology is the underlying technology of bitcoin. Without any centralized organization operation and management, bitcoin has been running very stably for many years (perfectly for seven years), and there has been no problem (no missing account). Therefore, some people have noticed its underlying technology and abstracted bitcoin technology, which is called blockchain technology, Or distributed ledger technology
what is centralization

the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent

the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers

the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high

at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know

so, in which fields can blockchain be applied, what kind of changes will it bring to our future life

the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud

core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people

Application:

1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment

2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute

3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city

4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords

in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.

2.

When Ctrip becomes a channel brand and a dominant company, the so-called decentralization gives other similar companies the opportunity to diversify 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

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. Qube exchange answers for you:
to apply blockchain, we must first understand the characteristics of blockchain: decentralization, openness, autonomy, non tampering information and anonymity
it is of great benefit to the following instries:
1. Art investment
using blockchain technology, we can track the source of art. Because every transaction has a digital certificate, and is unique, avoid black market transactions
2. Literary works
because blockchain is traceable, it can avoid the occurrence of piracy. Once a work is created, later people can it, and you can find it immediately
3. Finance
some financial payment and clearing systems are imperfect, especially cross-border payment. Blockchain is not only an information registration system, but also a payment system. Therefore, the account book can not be modified and open, so that it can serve the financial market;

5. First of all, blockchain itself has no business model to speak of
you are talking about the combination of blockchain technology and an instry. That is to say, "blockchain +" combines technology and instry deeply after combining specific projects to develop corresponding landing applications
the technical characteristics of blockchain and its application fields
① data can't be tampered with. Blockchain is a decentralized distributed database without centralized server, which can't be controlled by a certain person or an organization. Each node in the blockchain system stores one of the data. If the data on the node is changed, the blockchain system will be able to store one of the data, Then it can not be verified in the whole blockchain network. With this feature, it will be well used in finance, public administration data, audit data, etc
② distributed storage: in the area fast chain system, each running node has a complete data , which enables each node to independently verify and retrieve data, greatly increasing the reliability of the system. Combined with the characteristics of this blockchain technology, it is applied to games. We are familiar with the fact that our games are applied to a game server, It can greatly increase the stability of the game and enhance the game experience of the players.
③ anonymity. Traditional software clients need to register a user name and bind the mobile phone number. In order to increase the user's recognition, some will also increase the identity authentication. Combined with the blockchain technology, they are converted from the public key generated by the public cryptographic algorithm, This is usually a string of garbled characters. Bitcoin system is like this, but we don't know who is the operator behind it.
combined with this technical feature, we can make use of online payment, collection, property on the chain, etc. to greatly protect the user's information.

6. VAT invoice is also a kind of invoice. Enterprises with the qualification of general VAT taxpayer can apply to the competent state tax department for purchasing VAT invoice and issue it through the anti-counterfeiting tax control system. Enterprises with the qualification of general VAT taxpayer can dect vat by VAT invoice. Special invoice is the abbreviation of "VAT special invoice". An invoice issued for the sale of goods subject to VAT. After the implementation of the Provisional Regulations of the people's Republic of China on value added tax, in order to ensure the implementation of the tax dection system of value-added tax which belongs to extra price tax, it is printed and distributed for the use of enterprises. When taxpayers sell goods or taxable services, they shall issue special VAT invoices to the purchasers, indicating the sales amount and output tax amount respectively. The use of special invoice as dection voucher is limited to the general taxpayers who are both VAT buyers and sellers.

7. I don't think so. The original God's mine is refreshed frequently, and there are many refresh points, so don't worry about others digging your mine

8. Blockchain technology has a tamperable distributed ledger, which ensures the transparency and sharing of information, thus greatly recing the cost of building trust and reaching consensus between point-to-point business activities. This paper deeply interprets four typical business scenarios: supply chain finance, commodity traceability, science and technology medical and instrial Internet
1. Blockchain plus supply chain finance nowadays, the supply chain of most commodities, from providing raw materials to manufacturing finished procts, will involve several upstream and downstream small and medium-sized enterprises; And these enterprises are facing the pressure of unlocking supply chain working capital. Supply chain finance means that banks and other financial institutions make systematic financing arrangements for all member enterprises of the supply chain, so as to form a win-win situation between the core buyer enterprise and the supplier: the buyer optimizes the working capital, and the supplier generates additional operating cash flow, so as to minimize the risk of the whole supply chain. The traditional supply chain finance has three pain points: 1. Information can not be shared, low efficiency, poor credibility; 2. The circulation of bills is inconvenient, the settlement of contracts is slow, and there are often capital risks; 3. Credit cannot be transferred and financing is difficult. Blockchain can achieve the following functions: 1. Core enterprises, multi-level suppliers and financial institutions share transaction data, a / R and a / P data and protect business privacy; 2. The circulation of enterprise creditor's rights, automatic settlement of funds, and acceleration of enterprise payment and repayment; 3. The payment commitment of core enterprises is transferred between multi-level suppliers and financial institutions to transfer the credit of core enterprises
2. Blockchain traceability in the field of commodity traceability, the combination of blockchain and Internet of things technology can trace the whole process of commodity circulation, so as to avoid illegal vendors making use of the information asymmetry in the commodity chain to proce fake and shoddy goods. To prevent some participants from tampering with data or falsely claiming the loss of information when it is not concive to their own situation, resulting in the difficulty of proof and accountability. In addition, blockchain traceability can break through the information islands in different links of the supply chain and improve the cooperation efficiency of the supply chain
3. Blockchain helps the blockchain technology of medical services to open up many links, such as hospital prescription, pharmacist prescription review, drug distribution, drug payment, process supervision, etc. Through the distributed storage of blockchain and the accurate matching of information on the chain with patients, we can ensure the one-time dispensing effectiveness of prescriptions, eliminate prescription modification or abuse, and facilitate supervision. In the future, patient information, prescription information and drug circulation information can be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios
4. The integration of blockchain and IOT instrial Internet at the 5th World Internet Conference, the supet instrial Internet platform, which integrates the Internet of things and blockchain technology, was selected as the world's leading Internet technology achievements and became the only award-winning instrial Internet platform

in addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content right services, etc. In such instries as government, finance, instry and logistics, health care, retail and Internet, block has a wide range of business application scenarios.
