The impact of blockchain on hotel industry

1. blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true
blockchain can improve the way of data recording in audit. In the current network audit, although there is an early warning mechanism, it still needs auditors to judge and handle the abnormal records manually; Blockchain can automatically process the abnormal records through whether each node verifies and approves the block and the transaction information in it, whether the network node is attacked, and whether the account book of each node is complete, so as to make real-time audit possible. Auditors can directly access and query the effective information on the blockchain, judge whether the processing is reasonable and make corrections. In the blockchain, timestamps are used to record various transactions and operations, which can achieve historical traceability and tracking, and greatly improve the quality and efficiency of audit
blockchain can change the storage mode of audit data. In traditional audit, data are stored in an audit center server, which not only has the problems of high load and slow running speed, but also is vulnerable to attack; The blockchain audit system is a typical distributed storage, each node has the same backup, which can not only save the high cost and maintenance costs of the server, but also ensure the integrity of the data
semi public private chain can be used for audit. Blockchain can be divided into three forms: public chain, semi open private chain and full private chain. Considering the characteristics of audit instry, it is appropriate to adopt semi open private chain mode. For the audited units and enterprises, some trade secret information is not disclosed, but the pre selected nodes within the group decide the generation of the block. External suppliers can participate in the transaction but not the accounting process. Externally, it provides a third-party query node to query through the open API. In this way, it can not only ensure the internal privacy of the enterprise, but also enable the external auditors to implement real-time audit query.

2. Every kind of food has its own shelf life. Once we inadvertently sell or use expired food materials, it will have a great impact. The jinwowo blockchain can help managers manage and allocate the data of food types, storage conditions, delivery time and expired procts more conveniently and efficiently, and make corresponding processing with the help of the intelligent contract function of the blockchain.

3. Chongqing jinwowo analyzes the impact of blockchain technology on the instry: blockchain will determine the relationship between people and all the Internet including artificial intelligence. The change of this relationship will have a subversive impact on the mainstream Internet business model and create a new era of decentralization.

4. Teachers from Huo coin University believe that blockchain can be called a "hydrogen bomb" business tool, which binds strong network effect and financial leverage to realize the effective allocation of digital value in space and time. It plays an important role in the development of enterprises. If you want to learn more about blockchain, you can pay attention to them. At present, online live courses are also carried out.

5. These are two completely different concepts. In principle, there is no connection between them

6. The impact of jinwowo network technology sharing blockchain on the society:
in the future, blockchain will be applied in any field and bring great impact on human life. Blockchain application projects are roughly divided into: proof of existence, contract, Internet of things, authentication, market forecasting, asset trading, e-commerce, social communication, file storage, data API (Application Programming Interface), etc
if the blockchain technology can be used for preservation, there will be historical data of personal medical treatment, and there will be data available for future medical treatment or health planning. The real master of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology also helps to protect the privacy of patients.

7. It's equivalent to 20 M broadband, one yuan a day at most. Now it's all subsistence allowances. I have 50m broadband in my home, which costs 1.3 yuan a day at most.

9. Blockchain technology is an account book, and the accounts are open and transparent
