Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
Digital resources, which are generally characterized by irreplaceability, limitation, etc., and are not divisible, can be generated in a block chain based on Non-homogeneous Tokens (NFT) technology. Different block chains may use different NFT protocol standards to generate the digital resource. The current mainstream protocol standards include ERC721, ERC1155, ERC998, and the like. The ERC721 is the most common NFT protocol standard, and under the ERC721 standard, each generated digital resource has a unique identifier, and different digital resources are not replaceable with each other. Under the ERC1155 standard, the resource identifier does not correspond to one resource but corresponds to one type of resource, different types of resources are not replaceable, different resources in one type of resource are not different and can be replaced mutually, and the number of types of resources is finite. In the ERC998 standard, digital resources generated based on NFT technology may be bundled or combined with digital resources generated based on the homogenization certification (FT) technology (e.g., ETH coins). The solution of the embodiments of the present specification is applicable to various NFT protocol standards.
Fig. 1 is a system architecture diagram of a block chain applied in the embodiment of the present disclosure.
In fig. 1, a system of a block chain may include a block chain 101, a terminal device 102, a terminal device 103, and a terminal device 104. The block chain 101 includes 8 nodes, for example, from node 1 to node 8. Each node may be implemented as any device having computing, processing, capabilities, server or cluster of devices, etc. The lines between the nodes schematically represent P2P (Peer-to-Peer) connections. All the nodes store the full-amount accounts, namely the states of all the blocks and all the accounts. Wherein each node in the blockchain generates the same state in the blockchain by performing the same transaction, each node in the blockchain storing the same state database. Each node may be responsible for receiving transactions from clients and initiating consensus proposals to each slave node, including information such as the number of transactions in the block to be blocked (e.g., block B1) and the order of submission of each transaction. After the node in the blockchain successfully agrees on the consensus proposal, the nodes may perform the transactions according to the order of submission in the consensus proposal, thereby generating block B1.
It is to be appreciated that the blockchain shown in fig. 1 is merely exemplary and that embodiments of the present description are not limited to application to the blockchain shown in fig. 1. In addition, although fig. 1 shows that 8 nodes are included in the blockchain 101, the embodiments of the present specification are not limited thereto, and may include other numbers of nodes. Specifically, the nodes included in the block chain can meet the Byzantine Fault Tolerance (BFT) requirement. The byzantine fault tolerance requirement can be understood as that byzantine nodes can exist in a block chain, and the block chain does not show the byzantine behavior to the outside. Generally, some Byzantine Fault-tolerant algorithms require the number of nodes to be greater than 3f +1, where f is the number of Byzantine nodes, such as the practical Byzantine Fault-tolerant algorithm pbft (practical Byzantine Fault tolerance).
The terminal device 102, the terminal device 103, and the terminal device 104 may all be terminal devices that interface with nodes of a blockchain, and it should be noted that the terminal device 102, the terminal device 103, and the terminal device 104 may directly interface with the nodes of the blockchain, or may interface with the nodes of the blockchain through a service platform (for example, an e-commerce application platform that can provide a shopping service for a user, etc.), which is not limited in this aspect.
The terminal device 102 may be, for example, a terminal device held by a brand party, and the terminal device 103 may be, for example, a terminal device held by a product party of a commodity or a digital resource. The branded party may initiate a transaction to the blockchain through the terminal device 102 to authorize the copyright of its brand to the offeror in the blockchain. The product supplier can initiate a transaction to the blockchain through the terminal device 103 to sell the goods of the authorized brand on the blockchain, and create respective digital resources corresponding to the respective goods. The terminal device 104 may be, for example, a terminal device held by a buyer user of the product, and the buyer user may initiate a purchase transaction to the blockchain through the terminal device 104 to purchase the product sold by the seller on the blockchain and obtain the digital resource corresponding to the product. The buyer user can sell the commodity on the second-hand transaction platform, and transfer the digital resource corresponding to the commodity to the second-hand buyer on the block chain after the commodity is sold.
In the related technology, physical commodities are generally sold separately, some goods with broken money can be pirated and forged maliciously, and for the pirating and the forging of the physical commodities, the pirating and the forging are usually difficult to monitor technically, and only an anti-counterfeiting label can be used for proving the authenticity of the physical commodities. In the solution for processing digital resources in the system of the block chain shown in fig. 1, a digital resource corresponding to a physical commodity is set on the block chain, and after the physical commodity is sold, the digital resource corresponding to the physical commodity is associatively transferred to a buyer account. Therefore, digital management of the physical commodities on the block chain is realized, and the condition of physical commodity counterfeiting is avoided.
The embodiments provided in the present specification will be described in detail with reference to specific examples.
As shown in fig. 2, fig. 2 is an interactive flowchart illustrating a method for processing a digital resource based on a blockchain, which describes a process of creating and binding a digital resource a according to an exemplary embodiment. The method comprises the following steps:
in step 201, terminal device a1 sends a transaction Tx1 to create digital resource a to the tile chain node. Here, the terminal device a1 may be a terminal device owned by the brand b, or may be a service platform connected to a terminal device owned by the brand b. Digital resource A corresponds to brand P held by brander bA. Transaction Tx1 may be brand party b placing brand PAAfter authorization to the offeror p, initiated by the brand b.
Specifically, brand b may pre-link brand P through a blockchainAAuthorizing the offeror P to have the brand P sold through the blockchainAAnd the authority of the corresponding physical commodity. After authorization is complete, brander b may send a transaction Tx1 to the tile link point through terminal a1, which may include information for generating digital resource A in transaction Tx1, e.g., brand P may be included in transaction Tx1AInformation of brand authorization authentication, and the like. Wherein brand PAMay include, but is not limited to, information such as brand name, brand profile, and brand identity. Information for brand authorization authentication may include, but is not limited to, information such as information of a brand party, information of a producer, time information of brand authorization, and authorization details.
In step 202, the block link point generates an identification of digital resource a in response to receiving transaction Tx 1. Specifically, the transaction Tx1 invokes the pre-deployed contract C1, and the block link points may execute the logic code J11 included in the contract C1 by executing the transaction Tx1 to generate the identification of the digital resource a using a preset algorithm (e.g., a preset hash algorithm, or a preset encryption algorithm, etc.) based on the information included in the transaction Tx 1. It is to be understood that the present embodiment is not limited in the particular manner of generating the identification of the digital resource a.
In step 203, the block chaining point stores the identity of digital resource a in the block chain in association with the information of digital resource a. Specifically, the block link point may first obtain the information of the digital resource a from the data carried by the transaction Tx 1. Then, data D corresponding to the digital resource A is newly established in the contract state of the contract C1AData D corresponding to the digital resource AAIncluding a plurality of preset fields. Storing the identification of the digital resource A in data D in association with the information of the digital resource A according to the fieldsAIn (1).
Fig. 3 is a schematic structural diagram of data corresponding to a digital resource provided in an embodiment of the present specification. As shown in fig. 3, the data corresponding to the digital resource may include a plurality of preset fields, for example, basic information fields such as a field for recording identification information of the digital resource, a field for recording home account information of the digital resource, a field for recording home time information of the digital resource (i.e., time when the digital resource belongs to the current home account), and a field for recording validity period information of the digital resource may be included. Metadata information fields such as a field for recording brand information corresponding to the digital resource and a field for recording brand authorization authentication information corresponding to the digital resource may also be included in the data corresponding to the digital resource. The authorization authentication information may be used to authenticate the brand authorization to prove the validity of the commodity (i.e. to prove that the commodity is not counterfeit or pirated).
Optionally, the data corresponding to the digital resource may further include information of the product corresponding to the digital resource, for example, information such as a product name, a product profile, a product attribute, and a product code. The information of the goods corresponding to the digital resource may be recorded under a field corresponding to the goods information.
Note that, at the creation stage of the digital resource a, the attribution information (for example, attribution account, attribution time, and the like) corresponding to the digital resource a and the information of the product are unknown, and therefore, the data D is obtainedAThe field corresponding to the attribution information and the commodity information is recorded with an invalid initial value (such as null value), and the information of the commodity corresponding to the digital resource A can be added into the data D at the stage of binding the digital resource A and the commodityAUnder the field corresponding to the medium commodity information. At the stage of activating the digital resource a, attribution information corresponding to the digital resource a may be added to the data DAUnder the field corresponding to the attribution information.
In step 204, terminal device a2 sends a transaction Tx2 for binding digital resource a to the tile chain node. The terminal device a2 may be a terminal device owned by the offeror p, or may be a service platform connected to a terminal device owned by the offeror p. Specifically, the seller P sells the brand PAIn the case of the product p1 (physical product), it is necessary to collect the digital resource a and bind the product p1 to the digital resource a. Thus, a transaction Tx2 is initiated by the offeror p via terminal device a2, and the transaction Tx2 may carry information for item p1 such as the name of the item, the introduction of the item, the attributes of the item, and the code of the item.
The tile chain node binds commodity p1 with digital resource a in response to receiving transaction Tx 2. Specifically, the tile link point may acquire information of the commodity p1 based on the transaction Tx2 and store the information of the commodity p1 in the data D by fieldsAThus completing the binding so that the digital resource a has the determined corresponding commodity p 1.
As shown in fig. 4, fig. 4 is an interactive flowchart illustrating a method for processing a digital resource based on a blockchain according to an exemplary embodiment, where the method describes a process of picking up and activating a digital resource a according to the embodiment of fig. 2. The method comprises the following steps:
in step 401, terminal device a3 sends a transaction Tx3 to the block chain node requesting acquisition of digital resource a. Note that the terminal device a3 may be a terminal device held by the account C, a service platform connected to a terminal device held by the account C, or the like. Specifically, after the commodity p1 is successfully bound to the digital resource a, the seller p sells the commodity p 1. Meanwhile, the producer p may also generate a code corresponding to the digital resource a based on the information of the digital resource a, attach the code to a physical commodity package of the commodity p1 in the form of a two-dimensional code physical picture, store the code in a physical chip of the commodity p1 in the form of data, store the information of the commodity p1 of the server in the form of a two-dimensional code electronic picture, and so on. After the user holding account C successfully purchases product p1, the user can acquire the code corresponding to digital resource a and send transaction Tx3 to the tile chain node through terminal a 3.
In step 402, the block link point completes the acquisition of digital resource a based on transaction Tx 3. In particular, the transaction Tx3 may include the encoding, transaction Tx3 calls contract C1, and tile link points may parse the encoding included in transaction Tx3 by executing transaction Tx3, thereby executing logical code J12 included in contract C1, to convert data DAAnd adding attribution information and the like corresponding to the digital resource A under a field corresponding to the attribution information.
Optionally, data DAThe corresponding state of the digital resource A can be recorded, and before the digital resource A receives the activation stage, the corresponding state of the digital resource A is the inactivated state. Block Link points may also execute data D by executing transaction Tx3, thereby executing logical code J13 included in the contract C1AThe state corresponding to the digital resource A is changed into an active state.
Fig. 5 is a schematic structural diagram of account data corresponding to an account on a blockchain according to an embodiment of the present specification. As shown in fig. 5, the account data corresponding to the account on the blockchain may include basic information of the account, such as an account identification, an account type (e.g., a personal type account, or an institution type account), and an account status (e.g., a valid status, or a frozen status, or a disabled status). The account data may also include metadata information such as account personal information and a resource list of digital resources held by the account.
In a further alternative,the blockchain node may also execute the logic code J14 included in the contract C1 by executing the transaction Tx3, thereby adding the identification of the digital resource A to the account data DBIn (1). In the stage of transferring the digital resource A, account data D can be basedBThe included resource list performs validity verification for account C. For example, the identifier of the digital resource a is searched from the resource list, and at least in the case that the identifier of the digital resource a is found, it is determined that the validity verification is passed.
As shown in fig. 6, fig. 6 is an interactive flowchart illustrating a blockchain-based digital resource processing method, according to an exemplary embodiment, which describes a second-hand transaction (sale and purchase) process of an item p1 corresponding to the digital resource a involved in the embodiment of fig. 2. The method comprises the following steps:
in step 601, after account C is registered on application platform T1, item p1 (second hand sales) can be sold through application platform T1. Under the trigger of the event of selling commodity p1, terminal device a4 corresponding to application platform T1 may send transaction Tx4 to the tile chain link point, and transaction Tx4 carries the information of selling commodity p1 on application platform T1 with account C. The block link point, in response to receiving the transaction Tx4, stores information that account C sells the commodity p1 on the application platform T1 into the contract state of contract C1.
Alternatively, after account C is registered on application platform T2, item p1 may also be sold through application platform T2. Under the trigger of the event of selling commodity p1, the terminal device corresponding to application platform T2 may also send a transaction carrying information of selling commodity p1 on application platform T2 with account C to the tile chain node. The block link point also stores information on the sale of the item p1 by account C on the application platform T2 into the contract state of contract C1 in response to the transaction. Therefore, information for selling the commodity p1 on the application platform T1 and information for selling the commodity p1 on the application platform T2 are recorded in the contract state of the contract C1.
In step 602, after account D purchases article p1 on application platform T1, terminal device a4 corresponding to application platform T1 sends transaction Tx5 to the tile chain link point, and transaction Tx5 carries information that account D purchases article p1 on application platform T1. The block link point first determines whether the application platform T1 has sold the digital resource a based on the information recorded in the contract state of the contract C1 (i.e., determines whether the information recorded in the contract state of the contract C1 has sold the commodity p1 on the application platform T1). In the case where it is determined that the application platform T1 has issued the digital resource a, validity verification is performed based on the transaction Tx 5.
For example, the transaction Tx5 invokes the contract C1, which may include one or more preset rules in the contract state of the contract C1 for validity verification. The blockchain node may perform validity verification based on a preset rule included in the contract state of the contract C1 by executing the transaction Tx 5. The preset rule may be a restriction rule for a purchase account, a restriction rule for purchase time, a restriction rule for commodity price, or the like. It is understood that the present embodiment is not limited to the specific content of the preset rule.
In the event that validation fails, the sale of item p1 to account D may be terminated (e.g., the result of the validation failure is returned to application platform T1, such that application platform T1 terminates the flow of selling item p1, or terminates the transfer over the blockchain, etc.). In the case of successful validity verification, the operation of completing the sale of the commodity p1 to the account D may be performed (for example, the result of successful validity verification is returned to the application platform T1, so that the application platform T1 continues the flow of selling the commodity p1, or continues the transfer on the blockchain, etc.).
Alternatively, after performing the operation of completing the sale of item p1 to account D, the tile link point may send a message to application platform T2 that item p1 has been sold, so that application platform T2 may perform the operation of, for example, off-shelf item p 1. And deletes information of selling the commodity p1 on the application platform T1, information of selling the commodity p1 on the application platform T2, and the like in the contract state of the contract C1.
As shown in fig. 7, fig. 7 is a flow chart illustrating a method for processing a digital resource by a blockchain-based system according to an exemplary embodiment, which describes a process of transferring the digital resource based on the embodiments shown in fig. 2 to 6. The method comprises the following steps:
in step 701, after account D purchases and receives item p1, account D may perform a receiving confirmation operation through the terminal device it holds to confirm that the purchase is completed item p 1. Application platform T1 or a terminal device held by account D may send transaction Tx6 to a block chain node, transaction Tx6 being used to transfer digital resource a corresponding to commodity p1 from account C to account D.
In step 702, the blockchain node changes the home account of digital resource a in the blockchain from account C to account D based on transaction Tx6 in response to receiving transaction Tx 6. In particular, the transaction Tx6 invokes the contract C1, and the block link points may execute the logic code J16 included in the contract C1, thereby obtaining data D on the digital resource AAAnd changing the identifier of the account C into the identifier of the account D under the field corresponding to the attribution information, and updating the attribution time and other information.
Optionally, before changing the home account, the brand authorization authentication information included in the contract status of the contract C1 may also be checked, and in the case where the check is passed, the home account is changed.

For the device embodiments, since they substantially correspond to the method embodiments, reference may be made to the partial description of the method embodiments for relevant points. The above-described embodiments of the apparatus are merely illustrative, and the units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of one or more embodiments of the present specification. One of ordinary skill in the art can understand and implement it without inventive effort.
One or more embodiments of the present specification further provide a computer-readable storage medium storing a computer program, where the computer program is operable to execute the method for processing digital resources based on a block chain provided in any one of the embodiments of fig. 2 to 7.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD) (e.g., a Field Programmable Gate Array (FPGA)) is an integrated circuit whose Logic functions are determined by a user programming the Device. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a server system. Of course, this application does not exclude that with future developments in computer technology, the computer implementing the functionality of the above described embodiments may be, for example, a personal computer, a laptop computer, a vehicle-mounted human-computer interaction device, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device or a combination of any of these devices.
Although one or more embodiments of the present description provide method operational steps as described in the embodiments or flowcharts, more or fewer operational steps may be included based on conventional or non-inventive approaches. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual apparatus or end product executes, it may execute sequentially or in parallel (e.g., parallel processors or multi-threaded environments, or even distributed data processing environments) according to the method shown in the embodiment or the figures. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, the presence of additional identical or equivalent elements in a process, method, article, or apparatus that comprises the recited elements is not excluded. For example, if the terms first, second, etc. are used to denote names, they do not denote any particular order.
For convenience of description, the above devices are described as being divided into various modules by functions, which are described separately. Of course, when implementing one or more of the present description, the functions of each module may be implemented in one or more software and/or hardware, or a module implementing the same function may be implemented by a combination of multiple sub-modules or sub-units, etc. The above-described embodiments of the apparatus are merely illustrative, and for example, the division of the units is only one logical division, and other divisions may be realized in practice, for example, a plurality of units or components may be combined or integrated into another system, or some features may be omitted, or not executed. In addition, the shown or discussed mutual coupling or direct coupling or communication connection may be an indirect coupling or communication connection through some interfaces, devices or units, and may be in an electrical, mechanical or other form.
