Detailed Description
The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.
The invention discloses a building material supervision system based on a block chain, which is used for realizing supervision on various building materials produced by a manufacturer.
The invention relates to a building material supervision system based on a block chain, which comprises the following data.
1) And building and storing product material information corresponding to various building materials respectively based on the storage certificate of the production energy of various building materials uploaded by a manufacturer.
In practical applications, such as a manufacturer supplying A, B, C three types of building materials, the manufacturer uploads A, B, C deposits of the three types of building materials respectively to the blockchain system, so as to obtain A, B, C the right of the three types of building materials to trade in the building material supervision system.
Based on the fact that the manufacturer uploads the storage certificate of the building material production capacity to the blockchain system, the system can construct and store product material information corresponding to various building materials respectively, and as shown in fig. 1, the product material information can be specifically designed to specifically include building material models, building material performance parameters, building material unit prices and building material manufacturers.
2) According to the actual transaction of the construction materials with legal currency, aiming at the product material information corresponding to the corresponding construction materials, the Hash value corresponding to the transaction information of the corresponding construction materials is constructed and stored by a method for storing the transaction in a block chain.
In the building material monitoring system based on the block chain, which is designed by the invention, one kind of digital currency needs to be supported, but the building material monitoring system has no actual value unlike the existing digital currency; although it is referred to as currency, it more effectively acts as a medium for online evidence. Since it is impractical under the current industry regime to use digital currency for settlement of raw material transactions for the entire industry, the actual settlement currency of the transaction is still legal currency. In the design system of the invention, digital currency and legal currency 1:1 under the line are anchored, and when the transaction is completed under the line, both parties of the transaction need to complete the transaction of the same amount of digital currency on the line. Therefore, in practice, the digital currency is used to generate transaction-related data within the blockchain system.
Assuming that the developer has purchased a certain amount of A, B, C three materials to the manufacturer and actually paid a certain legal currency, the developer needs to be online, i.e., to generate an equal number of digital currency transactions simultaneously in the system designed by the present invention. In practical application, according to actual transaction of construction materials by legal currency, digital currency which is supported by a block chain system and has no actual value is used as a evidence storage medium, product material information corresponding to corresponding construction materials is constructed, and a method for storing transaction in a block chain is used for storing Hash values corresponding to transaction information of corresponding construction materials.
In practical application, as shown in fig. 1, the transaction information is specifically designed to include product material information, transaction amount, transaction time, private key signatures of both transaction parties, and for a Hash value corresponding to the building material transaction information, in practical implementation, the transaction information of the corresponding building material is processed by using the SHA256 algorithm to generate the Hash value corresponding to the building material transaction information.
The obtained Hash is crucial in the transaction process, and when the developer is supervised, the Hash value in the transaction process is an important component of the material verification information, that is, the material verification method adopted by the designed system proves the authenticity of the material by proving that the user actually pays and purchases the corresponding material. The blockchain technology provides key encryption capability, namely, the encryption operation executed by using the address ID corresponding to the blockchain system as a public key and a private key held by a manufacturer is provided; once the transaction is submitted, the corresponding contents such as the amount, the material information and the like of the transaction cannot be changed, and the buyer and the seller are bound.
Due to the foregoing, a purchaser may purchase a plurality of materials at once, but not necessarily all of the materials are used at the same time, so that only the Hash value of the transaction process is insufficient, i.e., the following.
3) And combining the Hash value corresponding to the building material transaction information with the building material product material information to generate a corresponding traceable Hash value, and storing the traceable Hash value. Since the product material information may be repeated, but the Hash value during a transaction is unique, whereas a single material in the same transaction only needs to be generated once, the Hash value generated again is theoretically unique.
In practical application, as shown in fig. 2, two Hash operations are continuously performed on each traceable Hash value until a unique root Hash is obtained, a material list Merkle tree in a block chain system is constructed and stored by each Hash value step by step, and the root Hash is stored in the block chain for traceable purposes.
Aiming at the building material supervision system based on the block chain, the invention further designs a supervision method, which comprises the following material tracing method.
Based on the RFID chip taking each traceability Hash value as the RFID code, the RFID code is arranged on the corresponding building material, according to each building material which is indicated to be used in the building design drawing, the RFID code in the RFID chip on the building material is read by the RFID reader-writer on the building construction site, and the block chain system is applied to obtain the building material product material information and the building material transaction information corresponding to the traceability Hash value as the RFID code, so that the authentication and traceability of the building material are realized.
The building material supervision system and the supervision method based on the block chain verify the trend of material information according to the route of figure 3 in practical application. The manufacturer uploads the actual yield to the design blockchain system, and the manufacturer is only likely to sign the corresponding online transaction if it receives a true payment. The developer now has paid for it in practice, and needs to handle the construction materials in the actual production. If the developer uses inferior quality material in place of the conforming material, the developer needs to dispose of the purchased conforming material in other ways. If he deals with a legitimate user who is also within the design blockchain system, then there is no way to generate new transactions and new RFIDs between them since the building material is nominally "used", otherwise this information would conflict with the production data provided by the manufacturer. And without a new RFID, the new buyer can not pass the supervision authentication on site, and the legal construction can not be realized.
Developers may also sell these materials to illegal users. In this case, the RFID has low cost and small volume. Due to the extremely low cost of applying the system, the system can expand the application range within the building industry as much as possible without being limited to large-scale projects. In this case, it is very difficult for the developer to deal with the illegal materials in large quantities, and there is a possibility that only a very small number of civil items will be targeted, but the handling in a small lot size means an increase in transportation cost and the like, and the developer has no intention of cheating from the viewpoint of profit.
The building material supervision system based on the block chain provides a feasible method for material supervision in the building industry through flexible application of the block chain evidence storage logic and the RFID characteristics. Also, those skilled in the art can make various equivalent modifications or substitutions to apply them to different scenarios without departing from the spirit of the present invention. Such equivalent modifications and substitutions are intended to be included within the scope of the present application as defined in the claims.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
