Air bank blockchain

1. 1. Consumption points management
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

2. Before, when we talked about decentralized applications, we always thought of foreign procts, such as Ethereum. But when we talk about this topic today, I think more about China's own Asch, a new generation of decentralized application development based on side chain technology<

arch is a decentralized application development, and it is also the first decentralized application in China. Its purpose is to help developers quickly create decentralized applications. The system is easy to use, flexible and safe
in terms of mode, it is similar to Ethereum and belongs to blockchain service, but the implementation mechanism is quite different. Taking Ethereum as an example, its biggest feature is that it greatly expands the functions of the script engine, adds new instructions such as reading blockchain, charging and jumping, and relieves stack memory, function call depth and script length restrictions. However, this method has a big disadvantage that the application code itself and the data generated by the application exist in the same blockchain, resulting in the rapid expansion of the blockchain
but arch is different. Its extensibility is not realized by transaction script, but by side chain. There is a main chain and several side chains (mainly provided by developers) in the ash system, but each chain only supports a limited number of transaction types. The logic of transaction or contract is written directly by the host language, not by the transaction script
the advantages are as follows: firstly, it reces the difficulty of contract programming; secondly, it avoids blockchain expansion; thirdly, each application can customize personalized blockchain parameters<

ash does not directly crypti (decentralized, blockchain based app store) or lisk (it is a new generation, allowing JavaScript development and distributed applications to use an easy-to-use, fully functional ecosystem), But it will refer to crypti's architecture and reuse some of its code, but not too much
there are two main differences.
crypti uses dpos, on which we add pbft algorithm to enhance consistency and rece double payment risk
we use C + + language to write some key moles, and nodejs is still used to write the non performance hot parts.

3. You can register as a member of haobtc, and then you can be drawn to our user group. There are many blockchain celebrities, who will learn a lot about blockchain.

4. Chongqing jinwowo analysis: blockchain also comes with the technology of transaction confirmation. To realize the automatic confirmation of movable property rights for all participants in the supply chain, and form a common non tamperable record on the block chain, so as to solve the pain points in the existing right registration and right realization.

5. From the published R & D results, there have been some significant progress in the core basic technology fields of blockchain, such as "consensus algorithm", "encryption algorithm", "smart contract situational test". The feature of complete "decentralization" of blockchain is not applicable in the financial field, and distributed and polycentric is expected to become a realistic choice. Blockchain, known as a disruptive technology, will become the key infrastructure of Internet Finance and even the whole financial instry. At present, capital and institutions at home and abroad are speeding up the layout of blockchain technology. Experts said that the rapid development of blockchain technology is becoming a hot spot for investment. This year, the financing amount of blockchain venture projects has exceeded 1.4 billion US dollars
in recent years, the investment field has been paying more attention to blockchain. Since the beginning of bitcoin, blockchain technology has been explored in many application fields. Nasdaq, New York Stock Exchange, Citibank and other overseas financial institutions are also trying to carry out business innovation of blockchain finance, and the development of blockchain technology is also a major focus in China., For reference only!

6. It has been sent out, please check.

7. In addition to the postal service and Weizhong, the Bank of Changsha is now cooperating with a public platform called SMIC blockchain, which seems to be a blockchain loan business.
