the quark blockchain team promised not to conct any pre digging and selling of points, let alone any fund-raising activities such as ICO and private placement

quark blockchain is a kind of blockchain based on PHP language, and ultimately hopes to provide distributed web, distributed storage and distributed streaming media playback services through blockchain technology

the goal is to build a blockchain project that belongs to everyone

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

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. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

5. The existence of pass is to meet the consensus mechanism, so as to realize the mining process of generating new blocks. If there are two sets of pass in a chain, then the consensus mechanism must be redesigned. But as I said upstairs, anything is possible.

6. The distributed bookkeeping mode of accompanying logistics + blockchain can make the business data and financial data of each enterprise recorded on the blockchain, so that the regulatory authorities can monitor them in real time and can not tamper with them. This solves the practical problems in traditional logistics, such as the difficulty of tracking documents, the difficulty of recovering the right of accounts receivable, and provides energy for enterprises.
