Detailed Description
In the embodiment of the present application, the off-line commodity capable of being circulated on-line may be a tangible commodity, such as an agricultural product, a food product, or the like, or an intangible commodity, such as a house ownership, a patent right, or the like, and correspondingly, the commodity entity may be a specific commodity stored in a certain warehouse, or may be various rights of the intangible commodity, and the sub-commodity entity may be regarded as several split items of the whole commodity, such as splitting a whole box of food into several small boxes, or splitting a digital asset into several right items.
The circulation transaction process in the scheme of the application is based on the block chain technology, the block chain technology has the characteristics of being not falsifiable, being traceable and the like, transaction information can be stored through the block chain to ensure that the transaction is completed, and meanwhile, offline commodities and online digital assets can be anchored by adopting the block chain technology, so that one offline commodity corresponds to one online digital asset only, and the uniqueness of the transaction is ensured.
Referring to fig. 2, an application scenario diagram of an offline commodity online circulation transaction method based on a block chain according to the present application is shown;
in the present application, the transaction process occurs between a plurality of terminals located at the nodes of the blockchain, wherein the terminals include the original owner (manufacturer) of the goods, i.e., the seller terminal; the warehousing terminal is used for storing the terminal of the commodity entity; the plurality of intermediary terminals are terminals which intentionally resale the purchased commodities, can be in a plurality of parallel relations, can purchase each component of one commodity by a plurality of intermediary companies respectively, can also be in a step-by-step relation, namely, the plurality of intermediary companies resale the commodities for a plurality of times, and finally reach the hands of consumers; the consumer terminal, in this embodiment, is a terminal that does not intend to resell the purchased product, or a terminal that wants to obtain the product entity immediately, and the consumer terminal may be multiple terminals, that is, one product may correspond to multiple consumers.
Example one
Based on the application scenario, the application provides an offline commodity online circulation transaction method based on a block chain, and referring to fig. 3, the method includes:
s100: the method comprises the steps that a first terminal obtains first to-be-traded commodity information stored on a block chain by a second terminal; the first commodity information to be traded comprises commodity entity affiliated location information and a first commodity data packet; in this step, the first terminal is the purchaser who has performed the transaction, the second terminal is the seller who has performed the transaction, and since the whole transaction process of the commodity may involve multiple transaction processes, the affiliated parties of the first terminal and the second terminal may also change correspondingly, as shown in fig. 4, when a first transaction process occurs when a commodity finally arrives at the consumer from the original owner through two intermediate merchants respectively, the second terminal will be the end where the original owner is located, and the first terminal will be the end where the first intermediate merchant is located; when the second transaction (first resale) occurs, the second terminal will be the first facilitator location and the first terminal will be the second facilitator location; when a third transaction (second resale) occurs, the second terminal will be the second facilitator's premises and the first terminal will be the consumer's premises.
In this embodiment, the information of the location where the commodity entity belongs refers to address information of the commodity entity initially stored by the original owner of the commodity, and the information is used for the consumer who finally obtains the commodity through transaction to find a corresponding address to obtain the commodity entity; the first commodity data packet is created by the seller (second terminal) of the current transaction, and includes, but is not limited to, information about what the commodity is, commodity price, and the like, and further includes information about all transaction processes of the commodity, such as the number of times the commodity has passed through transactions, original owner information, information about all intermediaries, and the like.
S200: the first terminal generates a transaction request according to the first commodity data packet and sends the transaction request to the second terminal; the transaction request at least includes the identity information of the first terminal (buyer) and other certification documents, such as enterprise qualification, etc., to certify the capability of purchasing the goods.
S300: the second terminal verifies the transaction request;
after receiving the transaction request, the second terminal (the seller of the transaction) needs to verify the identity of the buyer, if the buyer is an individual, the identity card, economic capability, individual credit, etc. of the buyer can be verified, if the buyer is an enterprise, the business license, tax condition, various qualifications, etc. can be verified, and when the second terminal considers that the various verifications meet the requirements, the second terminal can agree to execute the transaction with the buyer, and certainly, the second terminal can also determine whether to execute the transaction with the buyer sending the transaction request according to the individual preferences.
S400: if the transaction is agreed, the digital asset package corresponding to the commodity entity is sent to the first terminal after the transaction is finished; the digital asset package comprises an identification code uniquely corresponding to a commodity entity;
in this embodiment, the transaction mode is not limited, for example, the first terminal may pay directly for the second terminal, or a third party may be used for guarantee, where the transaction completion refers to payment completion (reaching the second terminal or reaching the third party), at this time, the online digital asset package uniquely corresponding to the offline commodity needs to be sent to the buyer, for the anchoring operation of the offline commodity and the digital asset package, various modes have been disclosed in the prior art, and it should be considered that the digital asset package is equivalent to each right of the commodity to be transacted, that is, the terminal where the digital asset package is located, and the terminal enjoys a certain right of the corresponding commodity, such as ownership, right of use, and the like. At the moment, the second terminal sends the digital asset package to the first terminal, namely, a certain right equivalent to the commodity is transferred to the first terminal, and the first terminal can immediately execute the next transaction process on the commodity without waiting for the commodity entity to reach the first terminal to start the next transaction process, so that the transaction process is greatly accelerated.
S500: the first terminal packs the transaction information with the second terminal and a second commodity data packet to generate second commodity information to be transacted, and the second commodity information to be transacted replaces the first commodity information to be transacted stored on the block chain;
after the transaction between the first terminal and the second terminal is completed, the transaction process information needs to be published on the whole block chain, and all nodes know that a certain right of the commodity is transferred from the second terminal to the first terminal, so the transaction information at least includes information of both transferring parties, for example, the seller a sells the commodity B, and in addition, if the buyer B wants to sell the purchased commodity again, the commodity information, the commodity price and the like need to be generated again to be transaction commodity information, that is, the first terminal in this step becomes the second terminal in the next transaction process, and the second to-be-transaction commodity information in this step becomes the first to-be-transaction commodity information in the next transaction process.
In addition, in order to prevent the information of the first commodity to be traded in the previous transaction of the terminal (buyer) of another node, the information of the second commodity to be traded generated after the transaction is completed needs to replace the information of the first commodity to be traded stored on the blockchain, and the replacement mode can be that the original information of the first commodity to be traded is deleted, or the information of the second commodity to be traded is added into the original information of the first commodity to be traded to indicate that the information is changed (invalid) in one transaction process, so that the buyer is led to directly obtain the information of the second commodity to be traded.
In practical applications, because there are many intermediate merchants, and there may be many intermediate merchants, the above steps S100 to S500 may be repeatedly executed many times, and each first terminal corresponds to the second terminal in the next transaction, and each second terminal corresponds to the first terminal in the previous transaction.
When the transaction occurs between the final intermediary and the consumer, the consumer who obtains the right of the commodity after the transaction is completed does not need to perform the transaction again for a while, at this time, as shown in fig. 5, the operation steps of the consumer obtaining the commodity entity need to be performed:
s600: the third terminal with the identification code sends a commodity acquisition request to a fourth terminal corresponding to the information of the commodity entity;
in this embodiment, the third terminal is the first terminal that obtains the digital asset package during the last transaction of the commodity. At this time, the first terminal is a customer location terminal, and it is not necessary to execute the step of S500, but to execute an operation of "picking up goods", that is, acquiring a goods entity from the acquired information to the location of the goods. The location end of the commodity is the fourth terminal, the attribute of the fourth terminal is related to the type of the commodity, for example, when the commodity is food or goods, the fourth terminal may be the end of a warehouse for storing the commodity, and if the commodity is the ownership of a house, the fourth terminal may be the client end of a real estate office, and the operation of "picking up goods" of the third terminal is similar to the operation of passing a house, etc.
The commodity acquisition request at least comprises an identification code, third terminal identity information of the request sending and the like, and the third terminal identity information is used for verifying the identity of the request end and finding a corresponding commodity entity according to the identification code.
S700: the fourth terminal verifies the commodity acquisition request; the fourth terminal identifies the identity and the identification code of the requester so as to judge whether the commodity entity in the request is located locally or not and whether the requester has the qualification of picking up the goods or not, and if the verification is not passed, failure information can be fed back to the third terminal.
S800: and if the verification is passed, the commodity entity is sent to the third terminal.
When the verification is successful, the fourth terminal may perform a step of transmitting the commodity entity to the third terminal, wherein the transmission mainly refers to a concept of practical meaning, such as transportation, right holder change, and the like, that is, after performing step S800, the buyer is considered to have obtained the commodity entity.
The method and the device have the advantages that when a certain commodity transaction process is executed, the next circulation transaction can be executed without waiting for the fact that a buyer really obtains a commodity entity, and on the premise that the block chain is verified, the follow-up transaction process can be executed when the buyer obtains the on-line identification code representing the commodity entity, so that the transaction efficiency is greatly accelerated, and the method and the device are particularly suitable for certain specific scenes.
Further, in another possible embodiment shown in fig. 6, the step S700 can be decomposed into:
s710: the fourth terminal receives a commodity acquisition request;
s720: the fourth terminal acquires transaction information corresponding to the identification code from the block chain, wherein the transaction information is information for performing all transactions on corresponding commodities; judging whether the third terminal is the holding end of the identification code or not according to the transaction information, and only using the first terminal after the last transaction as the third terminal to initiate a commodity acquisition request, so that some middlemans can be prevented from sending requests to a fourth terminal to cheat commodity entities;
s730: if the third terminal is the holding end of the identification code, the commodity acquisition request passes the verification, and if the third terminal has the real identification code, the identification code is the unique code of the corresponding commodity entity, and the unique code has the same effectiveness as the commodity entity, so that the verification can be judged to pass.
Further, in another possible embodiment shown in fig. 7, before the step S710, the step S700 may be further decomposed into:
s701: the fourth terminal extracts the identity information in the commodity acquisition request; the identity information indicates the identity of the terminal that wants to acquire the commodity entity.
S702: verifying the validity of the identity information; because the user sending the commodity obtaining request has the behavior of obtaining the identification code through an illegal channel, for example, the identification code legally obtained by other people is stolen for 'picking up goods', the identity information of the person sending the request is firstly verified at the moment, and if the user has the illegal behavior, the user does not have the qualification of 'picking up goods' or temporarily does not have the qualification of 'picking up goods', so that the fraudulent behavior is avoided.
S703: and if the verification is passed, extracting the identification code in the commodity acquisition request. When the identity of the requesting party is not in question, the subsequent step of S710 is performed, so as to further ensure the safety of the transaction process.
Further, in a possible embodiment, while performing the step S800, the method of the present application further includes:
s810: and the fourth terminal uplinks and stores the commodity entity transfer record. The record uplink storage aims to inform all nodes in a block chain, a consumer end finishes a goods picking-up process, the goods entity is not stored in an original storage position, and an online transaction process of the goods cannot be carried out any more. If the consumer needs to trade the commodity entity again, anchoring the commodity entity and the online digital asset package, chaining operation of the first commodity information to be traded, and the like need to be executed again, and a new circulation transaction is initiated again.
Example two
Based on the above application scenarios, the present application provides an offline commodity online circulation transaction method based on block chain, referring to fig. 8 and fig. 9, which is different from the above embodiment, that this embodiment considers the case of more than one consumer, i.e. one commodity may be circulated and transacted to at least two consumer terminals, e.g. a batch of goods may be sold to three a/B/C buyers respectively, and a house may sell its ownership and right of use (lease) to two customers respectively, so the method includes:
s100: the method comprises the steps that a first terminal obtains first to-be-traded commodity information stored on a block chain by a second terminal; the first commodity information to be traded comprises commodity entity affiliated location information and a first commodity data packet;
s200: the first terminal generates a transaction request according to the first commodity data packet and sends the transaction request to the second terminal;
s300: the second terminal verifies the transaction request;
s400: if the transaction is agreed, the digital asset package corresponding to the commodity entity is sent to the first terminal after the transaction is finished; the digital asset package comprises an identification code uniquely corresponding to a commodity entity;
s401: the first terminal splits the digital asset package into N digital sub asset packages, and each digital sub asset package corresponds to a unique sub identification code; each digital sub-asset package represents different assets, the asset types and sizes of the digital sub-asset packages can be different, the number of the digital sub-asset packages is not limited, one digital asset package can be divided into a plurality of digital sub-asset packages, the sub-identification codes have the same function with the identification codes, and the sub-identification codes and the identification codes (parent) establish a certain relation, namely the identification codes can be obtained through the sub-identification codes, so that the original commodity entity (the digital asset package before the division) can be found conveniently.
S501: the first terminal respectively packages the transaction information of the second terminal and a third commodity data packet corresponding to each digital sub-asset package to generate N pieces of third information to be transacted, and the third information to be transacted replaces the first information to be transacted stored in the blockchain;
s601: the third terminal with the sub-identification code sends a commodity acquisition request to a fourth terminal corresponding to the information of the commodity entity;
s700: the fourth terminal verifies the commodity acquisition request;
as shown in fig. 10, step S700 can be decomposed into:
s740: the fourth terminal receives a commodity acquisition request;
s750: the fourth terminal acquires the transaction information corresponding to the sub-identification code from the block chain and acquires the transaction information corresponding to the identification code corresponding to the sub-identification code; judging whether the third terminal is a holding end of the sub-identification code or not according to the transaction information;
s760: and if the third terminal is the holding end of the sub-identification code, the commodity acquisition request passes the verification.
S801: and if the verification is passed, splitting the commodity entity into sub commodity entities according to the sub identification codes, and sending the sub commodity entities to the third terminal.
The second embodiment can be applied to a scenario, for example, the user a packages the house ownership P1 and the house usage right P2 to generate a digital asset package for sale to the broker B, and usually, the broker B must wait for the house to pass under its name to continue selling the house ownership P1 or the house usage right P2, otherwise, the consumer C cannot agree to contract with the broker B; however, in the scheme of the application, the transaction between the user a and the intermediary B is a digital resource package (identification code) equivalent to a house right entity, the intermediary B receives the identification code, namely the identification code represents that the right item is transferred from the user a to the intermediary B, namely the intermediary B has the right to immediately perform the next transaction, and as the transaction process information is linked, any subsequent consumer can obtain the information for proving that the intermediary B has the transaction qualification from the chain, thereby preventing fraudulent transactions.
In the second embodiment, the same steps as those in the first embodiment have the same functions and effects as those in the first embodiment, and reference may be made to the description of the above method, which is not repeated herein.
According to the technical scheme, the off-line commodity on-line circulation transaction method based on the block chain is characterized in that the off-line commodity entity and the digital asset pack are anchored, the circulation transaction of the on-line commodity is realized based on the block chain technology, so that the rapid transaction of the same commodity among a plurality of terminals is realized, the transaction is not limited by whether a buyer obtains the commodity entity, the commodity circulation transaction process can be completed on the premise of ensuring the credibility of the transaction, and the efficiency of the on-line transaction is greatly improved.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein.
