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 of ordinary skill in the art based on the embodiments in the present specification without creative efforts shall fall within the protection scope of the present specification.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Because the design value of the commodity is intangible, the creator of the commodity design often has difficulty in putting the value of the commodity design into a controllable circulation link (such as authorizing others to design and produce the commodity) and dealing with the behavior of others to steal the design and produce the emulational commodity.
In one or more embodiments provided herein, the value of the commodity design is itemized on the chain by registering a plurality of digital commodities corresponding to the commodity design issued on the blockchain, so that the distribution of the digital commodities on the chain can be mapped to authorized use of the commodity design under the chain. Specifically, a digital commodity issued on a chain corresponding to a commodity design is associated to an authorized party, and the authorized party needs to use the commodity design on a commodity in a mode of consuming one digital commodity associated on the chain under the chain.
Therefore, the block chain can be used for storing and tracing the authorization process of the commodity design, and if the authorized party and the authorization party dispute about the authorization use affair of the commodity design, the credible record on the block chain can be used as the evidence for solving the dispute.
The block chain technique is described first below.
Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). In addition, there are various types of combinations, such as private chain + federation chain, federation chain + public chain, and other different combinations. The most decentralized of these is the public chain. The public chain is represented by bitcoin and ether house, and the participators joining the public chain can read the data record on the chain, participate in transaction, compete for accounting right of new blocks, and the like. Furthermore, each participant (i.e., node) is free to join and leave the system and perform related operations. Private chain the other way around, the write rights of the system are controlled by an organization or organization, and the data read rights are specified by the organization. Briefly, a private chain can be a weakly centralized system with strictly limited and few participating nodes. This type of blockchain is more suitable for use within a particular establishment. A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node in a federation chain typically has a physical organization or organization corresponding to it; participants maintain blockchain operation together by authorizing to join the system and forming a stakeholder union.
Whether public, private, or alliance, may provide the functionality of an intelligent contract. Intelligent contracts on blockchains are contracts that can be triggered to execute by transactions (typically client-initiated) on the blockchain system. An intelligent contract may be defined in the form of code.
It should be noted that in the blockchain field, the request for invoking the intelligent contract submitted to the blockchain system has a data structure specified by the blockchain protocol, which is generally referred to as a transaction. A blockchain transaction is a data structure, and the "transaction" in the blockchain-based transaction methods described in the embodiments herein refers to a transaction activity, and those skilled in the art can distinguish these two transaction expressions in meaning.
Taking the etherhouse as an example, the support user creates and invokes some complex logic in the etherhouse system, which is the biggest challenge of the etherhouse to distinguish from the bitcoin blockchain technology. The core of the ethernet plant as a programmable blockchain is the ethernet plant virtual machine (EVM), each ethernet plant node can run the EVM. The EVM is a well-behaved virtual machine, which means that a variety of complex logic can be implemented through it. The user issuing and invoking smart contracts in the etherhouse is running on the EVM. In fact, what the virtual machine directly runs is virtual machine code (virtual machine bytecode, hereinafter referred to as "bytecode"). The intelligent contracts deployed on the blockchain may be in the form of bytecodes.
For example, as shown in fig. 1, after Bob sends a transaction containing information to create an intelligent contract to the ethernet system, the EVM of node 1 may execute the transaction and generate a corresponding contract instance. The "0 x6f8ae93 …" in fig. 1 represents the address of the contract, the data field of the transaction holds the byte code, and the to field of the transaction is empty. After agreement is reached between the nodes through the consensus mechanism, this contract is successfully created and can be invoked in subsequent procedures. After the contract is created, a contract account corresponding to the intelligent contract appears on the blockchain and has a specific address, and the contract code is stored in the contract account. The behavior of the intelligent contract is controlled by the contract code.
As shown in fig. 2, still taking an ethernet house as an example, after Bob sends a transaction for invoking an intelligent contract to the ethernet house system, the EVM of a certain node may execute the transaction and generate a corresponding contract instance. The from field of the transaction in FIG. 2 is the address of the account of the initiator of the transaction (i.e., Bob), the "0 x6f8ae93 …" in the to field represents the address of the smart contract being invoked, and the value field is the value in EtherFang that is kept in the data field of the transaction as the method and parameters for invoking the smart contract. After invoking the smart contract, the value of balance may change. Subsequently, a client can view the current value of balance through a blockchain node (e.g., node 6 in fig. 2). The intelligent contract is independently executed at each node in the blockchain system in a specified mode, and all execution records and data are stored on the blockchain, so that after the transaction is completed, transaction certificates which cannot be tampered and cannot be lost are stored on the blockchain.
A schematic diagram of creating an intelligent contract and invoking the intelligent contract is shown in fig. 3. To create an intelligent contract in an ethernet workshop, the intelligent contract needs to be compiled, compiled into byte codes, deployed to a block chain and the like. The intelligent contract is called in the Ethernet workshop, a transaction pointing to the intelligent contract address is initiated, and the intelligent contract codes are distributed and run in the virtual machine of each node in the Ethernet workshop system.
It should be noted that, in addition to the creation of the smart contracts by the users, the smart contracts may also be set by the system in the creation block. Such contracts are generally referred to as foundational contracts. In general, the data structure, parameters, attributes and methods of some blockchain systems may be set in the startup contract. Further, an account with system administrator privileges may create a contract at the system level, or modify a contract at the system level (simply referred to as a system contract). In addition to the EVM in the ethernet bay, various virtual machines may be used in different blockchain systems, which is not limited herein.
After executing a transaction that invokes an intelligent contract, a node in the blockchain system generates a corresponding receipt (receipt) for recording information related to executing the intelligent contract. In this way, information about the contract execution results may be obtained by querying the receipt of the transaction. The contract execution result may be represented as an event (event) in the receipt. The message mechanism can realize message passing through an event in a receipt so as to trigger the blockchain node or a node device deploying the blockchain node to execute corresponding processing.
The structure of the event may be, for example:
Event：
[topic][data]
[topic][data]
......
in the above example, the number of events may be one or more; wherein, each event respectively comprises fields of a subject (topic) and data (data). The blockchain node or the node device deploying the blockchain node may perform the preset processing by monitoring the topic of the event, in case that the predefined topic is monitored, or read the related content from the data field of the corresponding event, and may perform the preset processing based on the read content.
In the event mechanism, it is equivalent to that there is a client with a monitoring function at a monitoring party (e.g. a user with a monitoring requirement), for example, an SDK or the like for implementing the monitoring function is run on the client, and the client monitors events generated by the blockchain node, and the blockchain node only needs to generate a receipt normally. The passage of transaction information may be accomplished in other ways than through the event mechanism described above. For example, the monitoring code can be embedded in a blockchain platform code running at blockchain nodes, so that the monitoring code can monitor one or more data of transaction content of blockchain transactions, contract states of intelligent contracts, receipts generated by contracts and the like, and send the monitored data to a predefined monitoring party. Since the snoop code is deployed in the blockchain platform code, rather than at the snooper's client, this implementation based on snoop code is relatively more proactive than the event mechanism. The above monitoring code may be added by a developer of the blockchain platform in the development process, or may be embedded by the monitoring party based on the own requirement, which is not limited in this specification.
The blockchain technology is different from the traditional technology in one of decentralization characteristics, namely accounting is performed on each node, or distributed accounting is performed, and the traditional centralized accounting is not performed. To be a difficult-to-defeat, open, non-falsifiable data record decentralized honest and trusted system, the blockchain system needs to be secure, unambiguous, and irreversible in the shortest possible time for distributed data records. In different types of blockchain systems, in order to keep accounts consistent among nodes recording accounts, a consensus algorithm is generally adopted to ensure that the above-mentioned consensus mechanism is adopted. For example, a common mechanism of block granularity can be implemented between block nodes, such as after a node (e.g., a unique node) generates a block, if the generated block is recognized by other nodes, other nodes record the same block. For another example, a common mechanism of transaction granularity may be implemented between the blockchain nodes, such as after a node (e.g., a unique node) acquires a blockchain transaction, if the blockchain transaction is approved by other nodes, each node that approves the blockchain transaction may add the blockchain transaction to the latest block maintained by itself, and finally, each node may be ensured to generate the same latest block. The consensus mechanism is a mechanism for the blockchain node to achieve a global consensus on the block information (or called blockdata), which can ensure that the latest block is accurately added to the blockchain. The current mainstream consensus mechanisms include: proof of Work (POW), Proof of stock (POS), Proof of commission rights (DPOS), Practical Byzantine Fault Tolerance (PBFT) algorithm, HoneyBadgerBFT algorithm, etc.
Fig. 4 is a flowchart illustrating a method for authorizing a commodity design based on a blockchain system according to the present disclosure, which may include the following steps:
s400: an authorizer client initiates a first transaction that invokes an intelligent contract in the blockchain system.
S402: and the blockchain system responds to the first transaction, runs intelligent contract to register the commodity design in the blockchain system based on the design registration information and forms a corresponding registration record.
S404: the authorizer client initiates a second transaction to the blockchain system that invokes the smart contract.
S406: and the blockchain system responds to the second transaction, and runs an intelligent contract to create corresponding digital commodities in the blockchain system based on the creation request information and the registration record and establish an association relationship between the created digital commodities and an authorized party.
S408: the authorized party client initiates a third transaction to the blockchain system that invokes the intelligent contract.
S410: the blockchain system, in response to the third transaction, runs an intelligent contract to reduce the amount of digitized goods associated with the authorized party by the usage amount in the blockchain system based on the usage request information.
The articles described herein may refer to articles having a certain design. The commodity design can be the appearance design of the commodity, and can also be the internal structure design of the commodity.
In commercial practice, merchandise design is also one of the drivers, sometimes even the most dominant driver, for consumers to purchase merchandise. For example, the design of art (a commodity with artistic attributes) often represents the main value of the art.
The authorized party for the merchandise design may often be the creator of the merchandise design (e.g., the artist who designed the artwork). In some cases, the creator of the merchandise design may entrust a professional intermediary organization, which may also be considered an authorizer, to manage the authorized use of the merchandise design.
The client described herein refers to a client of the blockchain system, and is used for interacting with the blockchain system, and specifically, can submit a transaction to the blockchain system, and the transaction can call an intelligent contract deployed in the blockchain system to implement a specific business logic.
The digital goods described herein can be understood as chain data issued in a blockchain system, and the chain data can be independently transferred from the owner and can represent a good. In other words, the one-time usage right of the commodity design under the chain is mapped to one digitalized commodity on the chain, and the one-time usage right of the commodity design is circulated on the chain.
In some embodiments, the digitized commodity may be defined using the digitized commodity protocol (ERC721), which is commonly referred to as Non-homogeneous Token (NFT). In addition, other digitized commodity protocols may be used to define digitized commodities.
Registering the commodity design on the chain may refer to submitting the relevant information of the commodity design (as registration information) to the block chain for evidence storage. After the commodity design is authored, the commodity design can be registered on the chain in time. The registration of the commodity design into the chain serves to provide a trusted basis of value for subsequent distribution of digitized commodities.
The first transaction may include design registration information carrying an identification of the design of the article. In addition, the design registration information may also carry other information, and the other information may be specified by an authorized party according to actual needs.
In some embodiments, the design registration information may also carry description information corresponding to the design of the article. The description information is used for uniquely describing the commodity design, namely, the commodity design can be uniquely determined according to the description information. The format of the description information may include: text and/or images.
For example, the overall structure of the product design and the details of each design can be depicted by using words as description information. For another example, a set of display pictures at various angles may be taken for the merchandise design, and a display video of the merchandise design may be taken, and these pictures and video may be used as the description information.
It should be noted that, in some embodiments, the design registration information may carry a hash value of the description information, considering that the processing pressure on the blockchain system may be caused by the excessive data size of the description information.
In some embodiments, if the authorized party is not the originator of the merchandise design, the registration information for the merchandise design may include originator information. When registering the commodity design, the intelligent contract can obtain the public key of the creator of the commodity design according to the creator information carried by the design registration information; and verifying the signature on the registration information by using the public key of the creator of the commodity design, and if the signature verification is passed, operating an intelligent contract based on the design registration information to register the commodity design in the blockchain system. Further, if the signature verification fails, it means that the registration of the merchandise design is not authorized by the creator, and therefore the merchandise design may not be registered in the chain.
In addition, the registration information corresponding to the commodity design may further include creation time corresponding to the commodity design.
The registration record formed by registering the design of the article may include design registration information, and may further include information such as registration time, validity period of the article design in the registered state, and the like.
The second transaction may include creation request information in the blockchain system to create one or more digitized goods corresponding to the registered good design.
In some embodiments, the authorizer client may monitor event information triggered by an authorization application for the commodity design by the authorizer client in the blockchain, and the authorizer client generates creation request information according to the monitored event information.
Further, the authorized party client may initiate a fourth transaction for invoking the intelligent contract to the blockchain system, where the fourth transaction includes authorization application information designed by the authorized party client for the commodity, the authorization application information includes identity-related information of the authorized party and an authorization quantity, the blockchain system may execute the intelligent contract based on the authorization request in response to the fourth transaction, verify the authorization qualification of the authorized party in the blockchain system, and if the verification is passed, trigger an event message including the authorization application information. Further, if the verification fails, the event message may not be triggered.
The authorization condition that the authorized party can obtain the use authorization for the commodity design can be specified according to actual business needs, and the authorized party meeting the authorization condition has authorization qualification. The intelligent contract can be provided with a checking logic for checking whether the authorized party is qualified in authorization in advance according to the authorization condition, wherein the input of the checking logic is the identity related information of the authorized party, and the output of the checking logic is a checking result for indicating whether the authorized party is qualified in authorization. The identity-related information of the authorized party may include, for example, a business qualification certificate of the authorized party (e.g., a personal certificate of employment, a business license of a legal person), region information corresponding to the authorized party (e.g., a place of residence of the personal person, a registration place of the legal person), a credit certificate of the authorized party (e.g., a bank deposit certificate, a bank loan record), and so on.
For example, an authorized party may be defined as: the authorized party should be up to 18 years old and should have the qualification to use the merchandise design. In this example, the fourth transaction may also include identification information and qualification documents provided by the authorized party, from which the intelligent contract may verify that the authorized party is 18 years old and has qualification for using the merchandise design.
Creating one or more digital commodities corresponding to the commodity design on the chain actually maps the usage right of the commodity design to a plurality of quantifiable, certifiable and negotiable digital commodities on the chain.
It should be noted that the number of issued digitized products may be N, where N is a natural number greater than 0. Each digital commodity represents one-time use right of the commodity design, and the value of the commodity design is required to be reflected through use. Therefore, it is equivalent to quantifying the value of a product design by a method of issuing a digitized product on a chain.
Note that the commodity value is intangible and is generally difficult to be an authentication target. And the digital commodity can be used as a right-confirming object due to the tangible property of the digital commodity. Therefore, it is equivalent to a method of issuing a digitized commodity on a chain, and the value of a commodity design is shaped for the purpose of authentication and distribution.
Establishing an association relationship between the created digital commodity and an authorized party, wherein the specific implementation mode can be as follows: the smart contract creates a data table for recording the association of the digitized good with the authorized party, in which a row of records may include two fields, one field including the identification of the authorized party and the other field including the identification of the digitized good.
An authorized party, when using a product design, needs to comply with the usage rules, i.e. to use the product design on a product in a manner that consumes a digitized product associated with the authorized party on the chain. It should be noted that the legitimate usage behavior recognized by the authorized party is only valid for using the merchandise design by consuming the digitized merchandise. Of course, it is difficult for the authorizing party to restrict the authorized party from intentionally not complying with the usage rules, but the authorizing party can prove the legal upper limit of the number of commodities to which the commodity design is applied by using the consumption condition of the digital commodities associated with the authorized party recorded on the chain, thereby facilitating the actual right maintenance of the authorizing party. In addition, based on the usage rules, a certain supervision effect can be generated for the authorized party, and the possibility of the authorized party doing harm is reduced.
The usage request information included in the third transaction may specify a quantity of the digitized merchandise that the authorized party wants to use, which may represent a number of times the authorized party wants to legally use the merchandise design under the chain. The intelligent contract can disassociate the usage amount of the digital commodity specified by the usage request information from the authorized party according to the usage request information, which is equivalent to realizing consumable usage of the usage amount of the digital commodity.
In some embodiments, the blockchain system may also run an intelligent contract to generate usage records on the blockchain system based on the usage request information.
In some embodiments, the blockchain system may run the intelligent contract to assign a validity period to each created digitized commodity after the intelligent contract is run to create the corresponding digitized commodity; the digitized good that exceeds the expiration date may then be disassociated from the authorized party. That is, the digitized goods may have an expiration date, and the N digitized goods that are issued are valid for a specified period and invalid outside of the specified period. As such, authorized parties often need to design a product for use on a product in a manner that consumes a valid digitized product with which they are associated on the chain.
Here, a data structure of a digitized product will be described. In the embodiments of the present specification, the data structure of the digitized product is not particularly limited, and is only described as an example.
For example, the party that generates the digitized commodity may include: generating a basic code according to the authorized party identifier, the authorized party identifier and the commodity design identifier; creating a data structure of the ith digital commodity corresponding to the commodity design according to the basic code and the ith unique index code; wherein i is 1, 2, …, N.
Wherein, the combination of the item code and the ith unique index code can be used as the data structure of the ith digital commodity. Alternatively, the combination of the basic code and the ith unique index code may be encrypted by using the key of the smart contract, so as to obtain the data structure of the ith digital commodity.
Accordingly, the means for authenticating the digitized article may include:
the blockchain system runs the intelligent contract execution in response to a fifth transaction that includes the data structure of the digitized commodity to be verified: analyzing the data structure of the digital commodity to obtain a first partial code and a second partial code; judging whether the first part of codes obtained by analysis is basic codes or not, and judging whether the second part of codes obtained by analysis is unique index codes of any digital commodity or not; if the judgment results are yes, determining that the data structure of the digital commodity passes verification; and if any judgment result is negative, determining that the data structure of the digitalized commodity is not verified.
FIG. 5 is a schematic illustration of registering merchandise values on a chain as provided by the present specification. As shown in fig. 5, the commodity may be an art, such as gold jewelry X, and artist a is a creator of a design value of the gold jewelry, where the value of the gold jewelry includes the gold value and the design value, and invokes a brand NFT smart contract deployed on the chain to register the design value as an NFT brand (the NFT brand may be understood as an NFT distribution basis) on the chain, so as to implement circulation and authorization of the design value by using the NFT.
Fig. 6 is a schematic diagram of chain publishing NFTs provided herein. As shown in fig. 6, following the example shown in fig. 5, a corresponding brand NFT is issued based on an NFT brand (i.e., a product design value), the required parameters are an artist signature, a design model identifier (i.e., a product design identifier), and an application issue number N (500), and N brand NFTs can be issued in a chain based on these parameters to quantify and shape the product design value, thereby realizing quantification, right determination, and circulation of the product design value.
In addition, the present specification provides an authorized use device for a commodity design, including a processing module applied to a blockchain system, a first initiation module applied to an authorizer client, and a second initiation module applied to an authorized party client;
the first initiating module initiates a first transaction for calling the intelligent contract in the blockchain system, wherein the first transaction comprises design registration information carrying a commodity design identifier of a commodity design; initiating a second transaction invoking an intelligent contract to a blockchain system, the second transaction including creation request information to create one or more digitized commodities corresponding to the registered commodity design in the blockchain system; in response to the third transaction, running an intelligent contract in the blockchain system to reduce the amount of digitized merchandise associated with the authorized party by the amount of usage based on the usage request information.
The second initiating module initiates a third transaction for calling the intelligent contract to the blockchain system, wherein the third transaction comprises the use request information of the authorized party to the digital commodity, and the use request information comprises the use number of the digital commodity;
the processing module responds to the first transaction, operates intelligent contract to register the commodity design in the blockchain system based on the design registration information and forms a corresponding registration record; and responding to the second transaction, and running an intelligent contract to create a corresponding digital commodity in the blockchain system based on the creation request information and the registration record and establishing an association relationship between the created digital commodity and an authorized party.
