Blockchain airbnb
blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
leou online culture and tourism platform is the world's first blockchain tourism platform covering six tourism fields, such as food, housing, transportation, tourism, shopping and entertainment. It transforms the old points system of enterprises to a certain extent and transforms it into new points independently issued by enterprises with blockchain as the underlying technology, realizing free trading and exchange of points, Make the best use of the service and function of points, help the service providers to achieve customer drainage, and help the tourism consumers to obtain greater benefits
2. Air ticket and hotel reservation: Russian Siberian Airlines (S7) and Alfa bank cooperate to sell air tickets on the blockchain. One of the main advantages of adopting this technology is to speed up the payment process<
3. Loyalty program of hotels and airlines
loyyal is a general loyalty reward platform based on blockchain and smart contract technology. It proposed to use blockchain technology to make tourists better obtain loyalty points in 2016 instry Theme Conference held by Du Yacht Hotel, so as to promote the development of tourism instry. In addition, Singapore Airlines (SIA) also announced in 2018 that it will launch a customer loyalty KrisFlyer program based on blockchain for Airbus
4. Track pilot's professional certificate and qualification
Airbus, a participant of hyperledger blockchain alliance, is also exploring the possibility of blockchain application. The test project is to track pilot's professional certificate and qualification by using blockchain
5. Credit consumption management
on the airbnb platform, reputation is extremely important. Only when the user's reputation reaches a certain level can he rent a specific type of house. Airbnb uses blockchain technology to better establish the reputation platform of merchants and passengers, and also to effectively store identity information
6. Digital identity authentication
Joanne Zen, founder of backpack chain in New Zealand, is leading the team to create BTA system, which combines the underlying blockchain technology with Internet application to create personal electronic digital identity authentication. When users register in the backpack chain app, in addition to the conventional registration process, they also need to scan the user's passport and upload face recognition information, which proces the unique mobile personal ID information in the world. Each ID information owner will have a string of keys, which only the information owner knows
7. Verify housing information
airbnb provides more than 2 million housing information from 191 countries and has received 60 million customers. P2P hotel website has achieved some success in optimizing the one-stop process of hotel leasing. It is also exploring the verification of housing information, establishing a short message communication system to enable customers to communicate with homeowners, and improving the payment experience
8. Electronic identity management
in Estonia, blockchain technology has been applied to the development of electronic identity projects. It is reported that non Estonian residents are allowed to apply for e-citizenship in the country, similar to a permanent residence card or identity card, which enables these residents to enjoy a series of services provided by the country. At present, Estonia uses this program to encourage talented people from all over the world to start their own businesses. Such plans will greatly promote the development of tourism in some destinations. You can pay more attention to bitMom
Financial instry
blockchain should be the most widely used in the financial instry
, for example, OMG (young model currency) in May 2017, omise announced that it was launching an electronic wallet with Alipay to integrate Alipay payment solutions into its own payment service suite, helping local e-commerce businesses in Thailand to accept online payment transactions from China tourists. p>
another example is PPT, which is a bill financial transaction system based on blockchain
gambling
the gambling instry probably entered the blockchain last year. Why does gambling favor blockchain? Blockchain provides a relatively fair guessing system. Why is it relatively fair? As can be seen from the previous introction, blockchain can not be tampered with or forged
for example, wicc is a rich application scenario that can realize asset issuance, guessing application, right traceability, mutual insurance, decentralized exchange, cross-border settlement, etc
for example, the STX stox application is designed to provide the full functionality of the forecast market application without any central server. Forecasting the market requires functions such as event planning, market making, providing information and analysis to traders, reporting event results, and of course collecting and paying
I believe that if the current lottery instry is set up on the blockchain, people's purchasing enthusiasm will be higher and higher, because too many insiders make people give up
Internet of things
there are still many applications of the Internet of things in the blockchain, because the traceability and timeliness of blocks are very suitable for this instry
for example, data is the concept of Internet of things, which is a decentralized P2P network. The data source can connect with any node in the whole network, and then publish the data, and the network will immediately send it to the subscriber. Horizontal scalability is achieved through fragmentation mode. This is very important for the timeliness and accuracy of Internet of things applications
game instry
for example, GTC (g coin) is a decentralized digital asset based on Ethereum erc20 issued by game.com, and G coin is committed to becoming the general digital currency standard of the global game instry
for example, mana is a distributed shared virtual platform. On this platform, users can browse and discover content, and interact with other people and entities. Users can also claim the ownership of virtual territory through the land ledger based on blockchain. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including interactive systems from static 3D scenes to games
there are many other instries. The great emperor did not list them one by one, but listed several representative instries. What is the point? It shows that blockchain is definitely not only the transaction of currency, it is a proct of the era change with real landing project and real practical use
in fact, the development of human society is just like the blockchain, which is irreversible and unstoppable. In my opinion, sooner or later, the blockchain will enter into thousands of households, no matter the ox or bear, hold the value currency in hand, and tonghuashun has begun to offer digital currency, which shows that the society is accepting it step by step, and the power of social development can not be blocked by any country or person
loyyal in New York is developing the "Du points" project for Norway and Du. The project takes blockchain as the underlying technology, and uses game based tour mode to help tourists find new attractions, so as to guide tourists' tour routes. Du points will encourage tourists to choose scenic spots according to their preferences through point tour, and carry out dynamic spot exchange according to their scores
2. Reservation management
(1) inventory management: wining tree is a B2B tourism inventory trading platform applied with blockchain, including air tickets, hotel rooms, car rental, destination tourism and activities
wining tree is the only open-source public blockchain in the tourism instry so far. It is built on the public Ethereum and has its own currency. It is a mature encrypted economic project. It aims to build a platform, so that suppliers can re control the inventory and display it almost at no cost, so as to eliminate the rent-seeking middlemen in the distribution system
(2) ticket booking: Russian Siberian Airlines (S7) and Alfa bank cooperate to sell tickets on the blockchain. One of the main advantages of adopting this technology is to speed up the payment process
in December 2016, S7 and alpha bank implemented the first letter of credit payment service by using Ethereum smart contract. Aeroflot, one of Russia's largest airlines, has also publicly said it is proposing the introction of digital assets and related technologies into its operations
(3) travel agent: Cool cousin, a British social platform, has launched an open source password token named cuz on the basis of Ethereum platform to exchange travel services and unique local information
cuz is a decentralized ecosystem that uses smart contracts to ensure the direct and secure exchange of knowledge and services between travelers and local people around the world. The mission of cool cousin is to carry out revolutionary travel business in every city on the earth by connecting tourists and like-minded local people cousins, so as to realize the intermediary free exchange of personalized information and personalized services
as a decentralized travel service booking platform, domestic tripio directly links global travel service providers (enterprises or indivials) and consumers through the blockchain network, and takes travel accommodation booking as the entry point to build a future travel service ecosystem based on trust, incentive and zero Commission
3. Loyalty programs for hotels and airlines
Singapore Airlines (SIA) announced in 2018 that it will launch a customer loyalty KrisFlyer program based on blockchain for Airbus. SIA will launch a mobile digital wallet application within six months of this year, on which users can buy SIA tickets
in addition, the application based on blockchain will allow KrisFlyer members to use mileage to participate in retail point of sale transactions, develop retail partnerships, and provide users with more consumption points, so as to improve customer motivation and loyalty
4. Track pilot's professional certificate and qualification
Airbus, a participant of hyperledger blockchain alliance, is also exploring the possibility of blockchain application. The test project is to track pilot's professional certificate and qualification by using blockchain
5. Credit consumption management
airbnb is studying how to use blockchain technology to verify the reputation and identity information of landlords and users. On the airbnb platform, reputation is extremely important. In the future, users can only rent specific types of houses when their reputation reaches a certain level. Airbnb uses blockchain technology to better establish the reputation platform of merchants and passengers, and also to effectively store identity information
Joanne Zen, founder of backpack chain in New Zealand, is leading the team to create BTA (backpack blockchain Travel Alliance) system, which uses the underlying blockchain technology combined with Internet application to create a new travel data trading platform and graally replace the traditional OTA System. Knapsack chain system is based on the concept of open source sharing, through the blockchain technology, to establish an efficient, transparent and reliable global database, and build a boundless ecological community of tourism credit consumption sharing
6. Digital identity management
in Estonia, blockchain technology has been applied to the development of electronic identity projects. It is reported that allowing non Estonian residents to apply to become e-citizens in the country enables these residents to enjoy a series of services provided by the country. At present, Estonia uses this program to encourage talented people from all over the world to start their own businesses
7. Tourism community Review
yuelv chain is a decentralized tourism community review platform based on blockchain, which is committed to building TripAdvisor in blockchain, and is also the first blockchain in the world to serve tourism real economy. The point-to-point network technology based on blockchain and smart contract enables every user or organization to participate in the process of building a shared ecosystem, thus forming a point-to-point "decentralized" ecosystem
8. Travel
Travel chain creates a leading instry tourism sharing platform through advanced blockchain, big data and artificial intelligence technology. It can not only establish a more fair and transparent travel system, but also provide new impetus for sharing travel ecology. In the travel chain ecology, all kinds of participants can share a new point-to-point decentralized travel world.
Share from DTV: how does the blockchain of DTV make profits in the end:
1. Build a blockchain ecosystem
Why do start-ups join in blockchain public chain projects one after another? Because it's a great opportunity. Any enterprise has the opportunity to create an ecosystem that subverts the existing pattern with its own ideas and operations. In this system, the currency designated by the ecosystem owner will circulate
because start-ups hold a certain amount of money and reserve some money for enterprises to dig, and the total amount of money is fixed, the faster the flow speed of the ecosystem is, the greater the demand for money is. More transactions chase less money, and the currency is bound to appreciate, but this idea is based on the fact that the currency is irreplaceable
now many research groups are developing cross chain technology to connect blockchains in different fields, so as to achieve the free circulation of money flow and data flow, and finally go to the exchange
in this case, the impact of a chain of money shortage on the ecosystem may not be as simple as the classical monetary theory, and the money price is likely not to follow the simple relationship between supply and demand. Designers need to think about this from a macroeconomic perspective
this is also the most attractive part of blockchain project: everyone is likely to establish new rules in this new field and become the manager of Qu centralized system. By then, the owners of the blockchain will have the ability to control the economy of the whole field - selling or inhaling digital currency will have a huge impact on the instry
2. Providing services for enterprises
providing services for enterprises is the main profit model of blockchain projects at the present stage, and cloud storage security skeptics are likely to turn to traceable and tamper proof blockchain service providers to seek maximum data security
for example, a blockchain start-up operating a data sharing platform, its main business includes providing data storage and data transaction services for customers, thus charging service fees and handling charges
there are many domestic start-up companies operating such businesses, such as cloud nest, border intelligence, magic chain technology, etc. Each company has excellent technology, but to make a profit, it may have to work hard on the operation
today, Tencent cloud's tbaas has joined this field and can provide services covering finance, supply chain, Internet of things, medical and other fields. It is believed that the competition and expansion of customers will become more difficult in the future
3. Smart contract participates in profit making
smart contract is like a contract that can be executed automatically. The validity of the contract is judged and enforced by machines instead of people. Its essence is still a piece of code, but the traceability and non tampering characteristics of blockchain can ensure that this piece of code runs automatically under the non trust mechanism. Blockchain is the precondition of smart contract operation
in practice, there are many opportunities for profit making through smart contracts, and smart contracts can solve these problems in a non black box way
in the running process of the program, the smart contract performs audit, classification information and other operations, which eliminates the interference of middlemen, and the record will not be artificially damaged, and the font on the file will not be blurred for a long time
but to some extent, the operators of smart contracts themselves become middlemen, and they automatically collect and pay audit fees through smart contracts. This kind of special intermediary service saves a lot of costs for customers, and its essence is realized by improving efficiency
4. Operation of special service driven system
many enterprises have their own exclusive fields in building blockchain community. Take the neurogenomics project led by geneticist church as an example. After enjoying the gene sequencing service provided by neurola, consumers can not pay in the form of legal money, but have to exchange legal money into the token issued by neurola
as more people exchange legal money for this token, nebula will successfully build a blockchain platform with gene data as the core, and after that, it will better carry out precision medical services
generally speaking, this mode relies on the actual technology, makes profits from offline services at the beginning of the project, and converts the legal money in the income into token in the process of making profits. With the progress of the project, the platform can carry out more precision medical services with the help of the data obtained from the start mode, and its profit methods have become diversified, but the whole process will not be separated from the entity
in the whole process of enterprise operation, token is mainly used as incentive, and token appreciation is not a problem that geneticists should consider
The original purpose of project 1CO is to crowdfunding in the market through pre-sale service. In 2013, the early 1CO company appeared in the financial field, and then quickly detonated the entire digital money market, resulting in the rise of speculationhowever, this storm came and went quickly. From 2013 to 2014 alone, many projects died in the speculation or were directly judged as fraud
according to Engadget data, 45.6% of the 902 crowdfunding based digital currencies have failed in 2017
Even so, there are still many survivors. These enterprises (including those that build the ecosystem) attach great importance to the role of token, and the appreciation of token will be calculated as part of the profits In essence, it is similar to an enterprise operating both financial assets (token) and operating assets (service) to manage operating assets to make financial assets profitable. However, if the proportion of "financial assets" is too large, the risk will come uninvited The foundation of sharing economy is to monitor the available resources and corresponding demands in real time and make adjustments to maximize the utilization of resources. For unicorns like airbnb, they have a mature management mode and stable cash flow. They try blockchain because blockchain technology can bring more transparent, more efficient and fairer systemsthis kind of enterprises use blockchain in the way of private chain or alliance chain. They don't need token to participate in circulation, and the nodes don't exist anonymously. They are interested in blockchain technology itself
with the blessing of blockchain technology, the manual input of ID information issued by the government will be transformed into the safe storage and verification of ID issued by the government. Customers and landlords can completely rely on the evaluation content. At the same time, the comments can be traced back to avoid the possibility of negative comments being deleted and the participation of the Navy
the profit model of airbnb and Tencent
the essence of sharing economy is to share information and resources seamlessly, directly and efficiently among strangers, so as to create value beneficial to both sides. To achieve this goal, the prerequisite is to trust each other and know the root. But since they are strangers, where does mutual trust come from? As a result, platforms that provide a sense of trust and promise fulfillment emerge as the times require - airbnb, Uber and didi taxi are among the best. By building and maintaining technology platforms, they aggregate, reorganize and allocate scattered resources and demands, verify the true identities, professional qualifications and background information of suppliers and demanders, provide transaction information, payment tools and comment records, and finally facilitate the transaction between the two parties
in the future of sharing economy, we must open up the channel of mutual trust at the indivial level, and blockchain is the key to open the channel. Sharing economy model is a new business model with P2P as the center, while blockchain is an innovative digital technology that drives comprehensive P2P transactions. Both of them expose their own loopholes and risks, and have great room for improvement and a long period of improvement. Blockchain and sharing economy can be mutual partners or competitors. Whether it is an enemy or a friend depends on the attitude and perspective of the authorities - whether they should take the initiative to consolidate and strengthen their advantages by taking the initiative to embrace each other, or whether they should wait for the day of marginalization? Airbnb, the leading enterprise of sharing economy, chose the former
decent can also be regarded as a kind of sharing economy project or a blockchain project.

fans of distributed ledger have put forward this view to people a long time ago, but blockchain still affects all aspects of our life. After all, this is the biggest innovation in the field of computer science. Although it faces a lot of opposition, there are also plenty of opportunities for exploration
blockchain not only exists in the field of bitcoin and finance
in order to make more people in the world understand the concept of blockchain, one way is to explain its concept and influence by writing books. A new book called "blockchain", which will be released on May 5th, touches on this issue
just as people expect to learn about blockchain from this book, one can refer to the most famous example of blockchain, which is the basis of bitcoin protocol. However, based on the source characteristics of the distributed ledger, there is a lot of room for innovation. Companies can explore how the distributed ledger affects our daily life
from 2015 to 2016, all venture capital poured into the blockchain market, and it was only a matter of time before the distributed ledger project was implemented. However, there is still a question: when will blockchain become a global trend, not just a small market, in which participants are not sure what they want to do with it
most people are aware of the impact of blockchain on the banking instry through faster and cheaper means of capital transfer. Some blockchain enthusiasts even think that the distributed ledger will create no cash in the next few years, that is, the cash will correspond to the digital . Whether this will happen remains to be seen, but it is very likely
let's look further. This technology will affect some recent sexual business models. Airbnb has recruited changetip employees for its blockchain solution. However, as we often see, the company has no plans to use bitcoin in the near future
but content creators can benefit from this technology, just as they can attract fans all over the world and make money with their own ideas. Bitcoin may have played a role in this process, but as the only available global payment scheme, it does not require banks to intervene or participate in financial services
the last but not least point is about data privacy. Distributed Ledger has a transparent nature. The solution must be able to let users show or hide as much or as little data as possible. One possible outcome is to give users complete control over their data, so that they can sell it to the highest bidder, rather than letting companies collect it for free.
