FIG. 3 is a functional block diagram of a material goods trading server 1 equipped with a material goods trading module 100 according to an embodiment of the present invention, and FIG. 3 is a functional block diagram of the material goods trading module 100 of FIG. 2.

As shown in FIG. 1, the material goods trading system includes a material goods trading server 1 on which the material goods trading module 100 according to an embodiment of the present invention is mounted, and an electronic payment server supporting electronic payment for material goods trading. ), Organizer and participants personal computer (4) or mobile terminal configured to register, view and participate in material goods transactions to view the material goods subject to material goods trading, and to perform sales, purchase, auction or exchange transactions ( 5) A plurality of user terminals (which may be an owner terminal, a participant terminal, a supplier terminal, or a consumer terminal) configured as one, and the material goods identification image output from the user terminal may be 2D image, 3D image, augmented reality image or virtual reality. Image display device such as HMD (6) which displays this in case of any one of the images, or receives and displays the image in the field of view, and material goods image. After photographing, a plurality of material article image acquisition units 200 interspersed and installed in a plurality of regions may be configured to be able to communicate through a communication network.

As shown in Fig. 2, the material goods trading server 1 performs a calculation process and executes a program to control the controller 10 for controlling the driving of the server, a keyboard for inputting and outputting data, a USB or SD card, an optical disk, or the like. An input unit 20 including a data reader for reading data of a memory device, a display unit 30 for displaying an operating state of a material goods transaction providing server 1 and providing an interface for interacting with a user, and It may be configured as a general server computer including a storage unit 50 on which the goods transaction module 100 is mounted, and a communication unit 40 for communicating with external devices through the communication network 9.

The material goods trading module 100, after receiving the material goods transaction registration from the organizer, informs the suppliers or demanders of potential participants to register the material goods transaction to induce participation, and then functions to mediate the material goods transaction. Configured to perform.

To this end, the material goods trading module 100, as shown in Figure 3, the material goods DB unit 110, the supplier or the consumer to the Internet service to perform the interaction for performing material goods trading as the organizer or participant Internet service unit 120 that provides an interface, transaction management unit 130 for controlling the execution of material goods transactions, video content generation unit for generating and storing a material goods confirmation image for confirmation of material goods subject to material goods trading (140), the registration of the material goods transaction, the notification service unit 150 for notifying the supplier or the consumer as the organizer and participant results of the material goods transaction, the big data processing unit for processing the cumulative stored material goods transaction information to generate valid data ( 160) and the mobile material goods trading service unit 170 that provides a material goods trading service through a mobile terminal 5, such as a smart phone, PDA, etc. It can comprise one.

In this case, the material goods DB unit 110 may store information related to the material goods, the information related to the transaction of the material goods are stored in the block is distributed to the nodes connected to the communication network 9 in the block chain form and stored Can be. And if necessary, the information related to the goods can also be configured to store in the block.

The present invention comprises a block generation unit 135 for generating a block after receiving the material goods registration information generated by a request of a plurality of organizer terminals or transaction information generated by a request of a plurality of participant terminals. For reference, in the present invention, a supplier who wants to sell a material article and a consumer who wants to purchase a material article may be an organizer or a participant depending on the situation. Thus, in the present invention, the host may be a supplier or a consumer, and the participant may also be a supplier or a consumer.

For example, when a material goods transaction is made by two participants (one supplier and one consumer), the two participant terminals transmit the transaction information on the transaction to the block generation unit 135 and the transaction information. The block generation unit 135 receiving the transmission may generate a block corresponding to the transaction information. In addition, one organizer registers the goods and the organizer terminal transmits the goods registration information to the block generation unit 135, and the block generation unit 135 receiving the goods registration information is sent to the goods registration information. The corresponding block may be generated.

In the present invention, the transaction management unit 130 permits the plurality of organizer terminals and the plurality of participant terminals to access the block to determine whether to conclude the transaction after the transaction of the goods, the plurality of organizer terminals and the If it is determined by a plurality of participants that the transaction is concluded as a valid conclusion, it may be configured to add the block to the blockchain.

4 is a block diagram of a block according to the present invention. Referring to FIG. 4, in the present invention, a block includes a block header and a block body, and the block header may include a version, a block hash of a previous block, a block generation time, and a valid factor.

In this case, the version may be a version of the material goods trading system using the block chain, the block hash of the previous block is a block hash value of the previous block, the block generation time means the time when the block is generated, and the effective factor Is an element for determining whether a corresponding block is valid. When determining whether a transaction is concluded using a valid factor, if the valid factor is smaller than a predetermined value, it may be determined that the transaction is a valid contract, and a block hash value calculated by using the value of the valid factor as one of input values is greater than a specific number. When the value is made smaller, it can be determined that the transaction is a valid conclusion.

The block body may comprise material goods transaction information and other information. Material transaction information may include information on the transaction of material goods. For example, if a supplier supplies raw material (ex. Steel plate) to the consumer for 10 million won, the information will be included in the material transaction information. Can be. In addition, the other information may include various information except for material goods transaction information.

In addition, since the block according to the present invention is added in the form of a block chain, it is configured to include a block hash. The block hash serves as an identifier of the block, and may be calculated by applying a hash function such as the SHA256 hash function, and may be configured to have a numeric value of 32 bytes.

Such a material goods trading system using a blockchain according to the present invention, the material goods transaction information is stored in the form of blocks, blocks are added in the form of blockchain, distributed to nodes connected to the communication network 9 including the organizer and participants Since the organizer, the participant, or a third party cannot arbitrarily modify or change the data stored in the block, the material goods trading system using the blockchain according to the present invention can greatly improve the reliability.

The material goods trading system using the blockchain according to the present invention may be configured such that only an authorized participant has access to the block, not everyone has access to the block. To this end, the transaction management unit 130 may be configured to allow a plurality of organizer terminals and a plurality of participant terminals to access the block.

If anyone is configured to access the block, then the additional speed of the block may be unnecessarily fast, thereby unnecessarily lengthening the blockchain, which may eventually lead to a decrease in system performance. In the present invention, only authorized participants can access the block, thereby preventing unnecessary speed of the block from being unnecessarily increased, thereby preventing performance degradation of the system.

The present invention is configured so that only the authorized participants can access the block, and may have a form like a private blockchain. In this case, any one participant secures a plurality of nodes and judges whether the transaction is concluded as a valid conclusion. We can try to add a, which can cause the whole system to collapse.

However, in the material goods trading system using the blockchain according to the present invention, at least one of a plurality of participant terminals transmits a permission request signal including a unique identification code to the transaction management unit 130, and the transaction management unit 130 Since the unique identification code is configured to transmit a permission approval signal to a participant terminal that transmits a permission request signal that does not overlap, it is possible to prevent any one participant from securing a plurality of nodes, thereby preventing the above problem.

In order to prevent any one participant from securing a plurality of nodes, when the permission request signal is transmitted by at least one of the plurality of participant terminals, the transaction management unit generates one public key corresponding to the unique identification code. It can also be configured to transmit a grant approval signal to the participant terminal that stores the public key and transmits the grant request signal only when the public key is not duplicated. In this case, the transaction management unit 130 may be configured to generate a secret key corresponding to the public key and decrypt it through an RSA public key encryption algorithm.

In addition, the material goods trading system using the blockchain according to the present invention can proceed with the voting whether to conclude the transaction, each node will exercise one vote. When more than half of the votes are voted to be valid judgments as to whether or not to conclude the transaction, it may be configured to determine that the transaction is a valid conclusion. In this case, each of the plurality of organizer terminals and the plurality of participant terminals operates as one node, and may be configured such that only the host terminal and the participant terminal receiving the permission approval signal can exercise the right to vote.

For example, when a trade of material goods is made by two participants (one supplier and one consumer) and the block generator 135 generates a block corresponding to the transaction, it is determined whether the block is valid. That is, the determination of whether the transaction is valid may be determined by voting.

At this time, both the host terminal and the participant terminal receiving the permission approval signal may be configured to be voters, or may be configured so that only the voters can vote by performing a separate voter registration process.

For example, if the organizer terminal and the participant terminal receiving the permission approval signal are configured to be the voting rights holder, the majority of the organizer terminal and the participant terminal, that is, the total number of nodes, is more than half of the valid judges on whether the transaction is concluded. When voting, the transaction may be determined to be a valid conclusion. If it is determined that the transaction is a valid conclusion, the block is added to the blockchain, and if the majority is not obtained and the transaction is not determined to be a valid conclusion, the block is discarded.

In addition, the present invention may be configured so that each node connected to the communication network 9 including the organizer and the participant inquires the basis data for the determination of the origin in the blockchain for the determination of the origin of the material article. Evidence data for determining the origin may be configured to be included in the material goods registration information generated by the request of the organizer terminal or transaction information generated by the request of a plurality of participant terminals, and may be recorded and stored in a block.

For example, a supplier, one of the participants, can submit (upload) a bill with data on the material goods he wants to supply, and the submitted bill can be stored in the storage unit 50 of the server 1. ), And then recorded and stored in a block. These bills of origin may include evidence of origin (eg certificate of origin) and may be used as evidence for determination of origin.

Looking at the operation of the determination of the origin of the goods in detail, first, the supplier requests the origin determination to the transaction management unit 130 through the supplier terminal to start the procedure for determining the origin. In this case, the bills and sales information used for the production of the goods to be judged, and if the documents of origin of the raw materials described in the bills exist in the blockchain, the identification information is also sent. Each node connected to the communication network 9 uses this information to inquire the information necessary for the determination in the blockchain together with the confirmation result of the confirmation node and to perform the origin determination.

In this case, each node may include a process of recording an identification code of a determination operation on the document when the document on which the decision request is based is in the blockchain, and recording that the document is used in the determination. This can help you to quickly find out if there are significant changes in the future, such as the credibility of the document, and you need to check the issue of another certificate of origin.

In addition, each node may include a process of processing unreliable information about data that is not verified through the block chain among the contents of the bill for which the request is made. If there is no evidence to determine the country of origin and the future verification cannot prove the country of origin, the material is treated as offshore. If reference is made to unconfirmed evidence on the blockchain for the material used, the data shall be included as evidence for the determination of origin but reflected as unreliable in the confidence rating.

Each node can assign a confidence level to the decision result. If the evidence of all materials in the bill of material is found to be reliable, the decision result is also treated as a trust level. If the evidence contains unreliable content and the results of the origin determination can change if this data proves to be untrue, the decision is treated as a caution class. The number of such cases is usually quantifiable, where the attention grade can be broken down or expressed as a confidence score (probability).

In addition, each node may include a process of storing the decision work history such as the status and trust level confirmed as a result of the decision work so that only the nodes participating in the check can be viewed and stored in the blockchain.

In the present invention, the material goods DB unit 110 of each component of the material goods trading module 100 is the supplier table 111, the consumer table 112, material goods confirmation image acquisition unit table 114, material goods image It may be configured to include a table 115, it may be configured to further include a transaction information table 113 as necessary.
