Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The application provides a site management method and device based on a block chain. The following detailed description is made with reference to the drawings of the embodiments provided in the present application, respectively.
For ease of understanding, certain terms are set forth below.
The block chain technology is an internet database technology and is characterized by decentralization, openness and transparency, so that everyone can participate in database recording. In short, if we assume the database as a book, reading and writing the database can be regarded as an accounting action. The principle of the blockchain technology is to find the person with the fastest billing speed in a period of time, to be billed by the person, and then to send the page of information of the ledger to other owners in the whole system. This is equivalent to changing all records in the database and sending to every other node in the whole network, so the blockchain technology is also called distributed ledger.
And accounting, wherein the block chain takes account page information (including transaction time, transaction content and the like) as original information to be hashed during accounting to obtain a hash value. The combination of the ledger information and the hash value constitutes the first block. About 10 minutes in the bitcoin system is billed once, i.e. each block generation time is approximately 10 minutes apart. When the second account is written, the hash value of the previous block and the current account information are hashed together as the original information. Thus, the second block not only contains the account page information, but also indirectly contains the information of the first block. Continuing the accounting in this way in turn, the newest block always contains indirectly all the previous accounting page information. All the blocks are combined to form a block chain, and the block chain forms a total account book which is convenient to verify (the last block is verified to be equivalent to the whole account book) and not changeable (any transaction information is changed, the hash values of all the following blocks are changed, and the transaction information cannot pass the verification).
The workload proving method has to increase the difficulty of accounting in order to ensure that only one person can account for about 10 minutes, so that the hashed result must begin with several 0 s. To satisfy this condition, a padding variable is introduced when hashing. The hash value will change continuously when any part of the original information of the hash is changed, so that when the hash is operated, the value of the padding value is changed continuously, and one padding value can be always found, so that the hash result starts with a plurality of 0 s. The only accounting right for this accounting is obtained by the mining machine nodes which find the appropriate filling value first. The process of finding a suitable fill value is computationally intensive, so the more computationally powerful the nodes of the mining machine, the hash value is first computed.
A site management method based on a block chain provided in a first embodiment of the present application is as follows:
as shown in fig. 1, when a node in a blockchain is a node where a user logs in, the node where the user logs in is recorded as a first node.
And 11, receiving a login request of a user, broadcasting the login request in the block chain so that each node in the block chain verifies the login request, and broadcasting a verification passing message when the verification passes.
In the initialization stage, the operation mechanisms of all the sites establish block chains together, and the operation mechanism of each site corresponds to a node in one block chain.
In this step, the first node receives a login request of a user sent by a user APP corresponding to the first node, and broadcasts the login request in the block chain, so that each node in the block chain authenticates the login request, and broadcasts an authentication passing message when the authentication passes. The login request includes user information, such as a user login account and a password. It should be noted that the user APP here may be an APP providing a site reservation service for the user, and may also be a management system PC end, where the management system PC end is configured to receive a user ID in an ID card scanned by a card reader, and send a login request of the user ID to the first node. That is to say, when a user uses an APP to log in, the first node receives a login request of the user sent by the user APP corresponding to the first node, and when the user uses an ID card to swipe a card to log in, the first node receives a login request sent by a management system PC end corresponding to the ID card. In the discussion that follows, user APP includes both of the above.
It should be noted that the user is registered in any node other than the local node in the blockchain. Only when the user registers in any node in the block chain, each node in the block chain can verify the login request. That is, the user can log in all the nodes in the blockchain as long as the user registers any node except the node in the blockchain, so that the site of the node except the node in the blockchain can be preset.
And step 12, receiving a first query request, and broadcasting the first query request in the block chain, wherein the first query request is used for querying the site information corresponding to other nodes except the node in the block chain.
In the step, the first node receives a first query request sent by a user APP and broadcasts in a block chain, and each node in the block chain confirms the first query request and records the first query request in a block chain account book. And after the first node receives the verification passing message broadcasted in the block chain, returning the verification passing message to the user APP, and allowing the user to inquire the site information of any other node except the first node in the block chain through the user APP.
And step 13, receiving the query results broadcast by other nodes except the node in the block chain.
In this step, the first node receives the query result broadcasted by other nodes except the node in the block chain, that is, the location information broadcasted by the node queried by the first query request, and the first node returns the query result to the user APP. The query result includes information of the site name, the site location, the open time, whether the reservation is made, and the like.
After this step, the user may subscribe to the venue of a node other than the first node based on the query results. The user APP sends the reservation request to the first node, the first node broadcasts the reservation request in the block chain, and each node in the block chain confirms the reservation request and records the reservation request in the block chain account book. And the first node receives a subscription success message broadcasted by the node corresponding to the subscription request, returns the subscription success message to the user APP, and completes the subscription. The booking request carries information such as a place number, booking time and the like. After the user has subscribed the sites of other nodes except the first node, the user needs to pay for the order, and the process of paying is the same as the process of subscribing the sites of other nodes except the first node, which is referred to the above process and is not described herein again.
In the application, the block chain technology is applied to the sports stadium leasing industry, and the problems that the user authorities of different operation mechanisms are not universal and the personal information leakage risk is high are solved. The intercommunication of user registration information, the enhancement of data security and the improvement of user experience are realized through the block chain technology. The operating institutions in each site join the block chain together, and user registration information of each site is linked up, wherein the user registration information on the chain is visible to all the operating institutions and invisible to non-block chain members. The nodes of each operation mechanism of the block chain can call the user registration information on the chain for user authentication, thereby realizing mutual recognition and intercommunication of the user registration information. For the same user, the user APPs of all nodes in the block chain can be logged in only needing to be registered once in the node of any block chain without switching a plurality of APPs or carrying a plurality of membership cards, and the site information corresponding to other nodes except the logged-in node in the block chain can be inquired. User experience is greatly improved, use convenience is improved, geographic limitation is broken, and potential users are indirectly added to operation mechanisms in various places.
In addition, the block chain information is ensured to be safe and not to be tampered through the cryptography of the block chain technology, the personal data safety is enhanced, and the information leakage risk is effectively reduced.
In some embodiments, as shown in fig. 2, when a node in the blockchain is a node registered by the user, the node registered by the user is marked as a second node, and the method further includes:
step 21, receiving a registration request of a user, broadcasting the registration request in the block chain, so that each node in the block chain registers the user according to the registration request, and broadcasting a registration success message when the registration is successful.

The registration request includes user registration information, such as a user registration account and a password. For the same user, the second node is a node registered by the user, and the first node is any other node than the second node in the block chain.
