Background

A party in possession of intellectual property rights (an authorizing party) may authorize an individual or an organization (an authorized party) to use intellectual property rights in practice. For example, a party who owns the copyright on an animation may authorize a coffee cup manufacturer to print an animated character in the animation on the coffee cup that it manufactures. For another example, a party who owns a drug patent may authorize a pharmaceutical factory to produce the corresponding drug.

The authorized party often needs to pay the authorized party for the usage, however, both parties have trust challenges in this regard.

the client of the authorized party calls an intelligent contract in the block chain network to execute the authorization request step: determining order information designated by an authorized party and triggering an event message containing the order information; the order information specifies intellectual property and use fee which are requested to be authorized to use;

after monitoring the event message containing the order information, at least one client of the authorization party calls an intelligent contract in the block chain network to execute an order confirmation step and an order withdrawal step; the order confirmation step includes: creating an order based on the order information and deducting the usage cost from the chain balance of the authorized party; the order withdrawal step comprises the following steps: triggering an event message requesting to cash out the order;

and after determining that the order is requested to be presented, the down-link account management device unfreezes the down-link balance matched with the authorization cost in the down-link account of the authorized party, and transfers the down-link balance to the down-link account of the at least one authorized party.

According to a second aspect of one or more embodiments of the present specification, there is provided a digital asset application method based on the payment method of the first aspect, comprising:

the client of the authorized party calls an intelligent contract in the block chain network to execute the asset application step: determining application information designated by an authorized party and triggering an event message containing the application information; the application information specifies intellectual property rights authorized to be used and application use times N;

after monitoring the event message containing the application information, at least one client of the authorized party calls an intelligent contract in the blockchain network to execute issuing steps and association steps; the issuing step includes: issuing N digital assets corresponding to the intellectual property; the association creating step includes: creating an association between an authorized party and the N digital assets;

wherein the authorized party legitimately uses the intellectual property right once in a manner that consumes one of the digital assets with which the authorized party is associated on the chain.

According to a third aspect of one or more embodiments of the present specification, there is provided another digital asset application method based on the payment method of the first aspect, including: the client of the authorized party calls an intelligent contract in the block chain network to execute the asset application step: determining application information designated by an authorized party and triggering an event message containing the application information; the application information specifies intellectual property rights authorized for use during a specified period;

In the above technical solution, an intellectual property right use authorization system is established based on a blockchain network, and an authorized party needs to map at least part of a down-chain balance in its down-chain account to an up-chain balance in an up-chain account, and use the up-chain balance to purchase an intellectual property right use right. An authorized party can put forward an order request through an intelligent contract in a block chain network, wherein the order request carries order information and specifies intellectual property and use cost which are requested to be authorized to use. The intelligent contract triggers the order information in the form of event messages, each client of the authorized party of the intellectual property right decides whether to authorize or not after monitoring the order information (in the case of multiple authorized parties, each authorized party can call the intelligent contract to vote, and the intelligent contract counts out the voting result), if each authorized party decides to authorize, the intelligent contract can create an order according to the order information and deduct the use cost from the chain balance of the authorized party. In this way, the order of the authorized party for purchasing the usage right of the intellectual property right is stored in the chain, and the usage fee is automatically deducted by the intelligent contract and the paid usage fee is recorded in the order (which is equivalent to being locked in the order), so that the association between the usage fee paid by the authorized party and the intellectual property right authorization can be clarified.

Each authorizing party can execute the order cashing step through an intelligent contract in the block chain network at any time, namely cashing the use charge locked in the order and triggering the use charge to be transferred from the down-chain account of the authorized party to the down-chain account of each authorizing party. Therefore, the order withdrawal record of the authorizer can be stored on the chain and cannot be repudiated, and meanwhile, the financial supervision institution can conveniently supervise the income of the authorizer by taking the order withdrawal record as a credible basis.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.

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.

Currently, a party (authorizing party) who owns intellectual property rights can authorize an individual or an organization (authorized party) to use the intellectual property rights in practice. For example, a party who owns the copyright on an animation may authorize a coffee cup manufacturer to print an animated character in the animation on the coffee cup that it manufactures. For another example, a party who owns a drug patent may authorize a pharmaceutical factory to produce the corresponding drug.

In practice, in the process of authorizing intellectual property rights to be used by an authorized party, the following trust problems exist:

1. before the authorizing party authorizes the intellectual property right to the authorized party for use, the authorizing party often achieves a limiting term about the use of the intellectual property right with the authorized party, wherein the limiting term can limit the use times of the intellectual property right by the authorized party or limit the authorized party to use the intellectual property right for a plurality of times in the use period.

However, the authorized party is difficult to trace back on the implementation of the terms of the restrictions. The authorized party may not comply with the terms of the restrictions, overuse the intellectual property or continue to use the intellectual property beyond the period of use. Even if the authorized party knows that the authorized party has the behavior of not complying with the limitation terms, since the intellectual property right is intangible and has repeatability, the authorized party has difficulty in distinguishing specifically which usage behavior of the authorized party is legal and which usage behavior is illegal, which means that the authorized party can obtain clear evidence that the authorized party does not comply with the limitation terms.

2. The authorized party often needs to pay the authorized party for the use of the intellectual property. However, since intellectual property rights are intangible, it is difficult in practice to unambiguously associate the payment actions of an authorized party with the intellectual property rights themselves. That is, even if the authorized party receives a fund from the authorized party, the authorized party may not recognize the fund as the usage fee of the intellectual property right and make a repudiation.

3. The authorized party may further transfer at least part of the right of use of the intellectual property to other individuals or organizations (the transferee), however, in such a complicated circulation relationship, the authorized party has difficulty in tracing the circulation path and easily loses control over the own intellectual property.

4. In practice, the products manufactured by using intellectual property are usually called intellectual property products, and the authorizing party and the authorized party will usually make a contract in advance for what intellectual property products can be manufactured, and the authorizing party wants to trace back which intellectual property products are manufactured by the authorized party using intellectual property. Therefore, how to prevent an authorized party from abusing intellectual property for product manufacture is the one in prime for the problem to be solved.

Aiming at the trust problems in the above 4 aspects, the present specification respectively provides a plurality of technical solutions implemented based on the blockchain technology. It should be noted that any combination of these technical solutions may be combined into a new technical solution, and the combined new technical solution should also be within the scope described in the present specification.

Block chain techniques are described herein.

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 network and perform related operations. Private chains are the opposite, with the network's write rights controlled by an organization or organization and the data read rights 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 jointly maintain blockchain operation by authorizing to join the network and forming a benefit-related alliance.

Whether public, private, or alliance, may provide the functionality of an intelligent contract. An intelligent contract on a blockchain is a contract that can be executed on a blockchain system triggered by a transaction. An intelligent contract may be defined in the form of code.

Taking the ethernet as an example, the support user creates and invokes some complex logic in the ethernet network, which is the biggest challenge of ethernet to distinguish from 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 network, 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. In other words, an intelligent contract causes a virtual account to be generated on a blockchain that contains a contract code and an account store (Storage).

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 network, 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 transaction initiator (i.e., Bob), the "0 x6f8ae93 …" in the to field represents the address of the smart contract called, and the value field is the value of tai-currency in the etherhouse, and the data field of the transaction holds the method and parameters for calling 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 network 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. An intelligent contract is created in an Ethernet workshop and needs to be subjected to the processes of compiling the intelligent contract, changing the intelligent contract into byte codes, deploying the intelligent contract 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 network.

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 networks 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 EVM in the ethernet, different blockchain networks may employ various virtual machines, which is not limited herein.

After executing a transaction that invokes a smart contract, a node in the blockchain network generates a corresponding receipt (receipt) for recording information related to executing the smart 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]

......

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.

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 networks, in order to keep the ledger consistent among the nodes recording the ledger, a consensus algorithm is generally adopted to ensure that the consensus mechanism is the aforementioned mechanism. After a node (e.g., a unique node) creates a block, other nodes record the same block if the created block is recognized by other nodes. The process of the generated block gaining acceptance by other nodes is a consensus mechanism. 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.

Some concepts that will be used later are presented herein.

Intellectual property: typically including copyright, patent rights, trademark rights, service logos, manufacturer names, origin names, new plant variety rights, integrated circuit layout design exclusive rights, and the like. The intellectual property right has intangibility and reusability, and all parties of the intellectual property right can authorize others to use the intellectual property right.

The authorized party: usually the owner of the intellectual property. The authorized party may obtain the benefit by granting intellectual property to others. In practice, the authorized party of intellectual property rights may have more than one party.

The authorized party: the party having intellectual property right authorization relation with the authorizing party directly cooperates with the authorizing party in intellectual property right use authorization.

The transferee: at least part of the right to use intellectual property is secondarily passed from the authorized party to the party.

The transferee: at least part of the right of use of the intellectual property is again streamed from the transferee to the party to which it is transferred. It can be understood that the right to use the intellectual property can be continuously circulated for many times to form a circulating chain.

A client: refers to a client of a blockchain network, also called a blockchain client. The blockchain client may or may not be a node of a blockchain network (as is the case with a public-link network). The blockchain client can initiate a transaction to the blockchain network, and the intelligent contract in the blockchain network is called through the transaction, so that the blockchain network executes the business related steps of the transaction request based on the code logic recorded in the called intelligent contract. The client of the authorized party is the client of the authorized party side, the client of the transferee is the client of the transferee side, and the client of the transferee is the client of the transferee.

Digital assets: it is the intelligent contract in a blockchain network that is based on some digital asset protocol defined data structure. The digital assets on the chain are the mapping of the objects under the chain on the chain, and the digital assets have uniqueness and have anchoring relation with the objects under the chain. Alternatively, the digital assets may be defined using the currently popular digital asset protocol (ERC721), which is commonly referred to as Non-homogeneous Token (NFT). In addition, other digital asset protocols may be used to define digital assets.

Several technical solutions implemented based on the block chain technique are introduced below.

The specification firstly provides an intellectual property right use authorization basic scheme, which comprises the following steps:

on one hand, the client of the authorized party calls an intelligent contract in the block chain network to execute the asset application step: determining application information designated by an authorized party and triggering an event message containing the application information; the application information specifies intellectual property rights authorized for use.

On the other hand, after monitoring the event message containing the application information, at least one client of the authorized party calls the intelligent contract in the block chain network to execute the issuing step and the associating step; the issuing step includes: issuing at least one digital asset corresponding to the intellectual property; the step of associating comprises: an association between the authorized party and the at least one digital asset is created.

In this way, the main body (which may be the authorized party or the transferee to which the authorized party transfers at least part of the intellectual property right) under the chain has the right to use the intellectual property right needs to legally use the intellectual property right once in a manner of consuming one digital asset issued on the chain, and a record of legally using the intellectual property right is left on the chain once, so that the authorized party can conveniently trace the intellectual property right. Specifically, the authorized party may initiate a transaction to the blockchain for consuming one or more digital assets, the transaction invoking a smart contract that places the digital assets specified by the transaction from an unconsumed state to a consumed state indicating that the intellectual property usage opportunities anchored by the digital assets have been implemented after determining that a number of the digital assets specified by the transaction have an association with the authorized party in the chain and have not been consumed.

By "legitimate use" is meant that the usage behavior conforms to the usage restriction terms agreed upon by the authorizing party and the authorized party. In practical applications, if an authorized party finds that the one-time usage behavior of the authorized party is not recorded in the chain by consuming one digital asset, the one-time usage behavior can be considered illegal.

As used herein, the term "consuming" a digital asset is understood to mean that each digital asset can only be called once, and once called once by its associated subject, is "consumed" and is no longer valid.

In practice, multiple authorized parties may share the same intellectual property, in which case, when determining whether to authorize the intellectual property to the authorized party, the multiple authorized parties need to make a decision based on some decision mechanism. For example, a vote may be made among the multiple authorized parties, each authorized party submitting a signature of the vote to the intelligent contract, and the intelligent contract performs statistics to determine whether to authorize or not. That is, the smart contract needs to collect the signatures of a specified number of authorized parties among the multiple authorized parties before the issuing step and the associating step can be performed.

Further, in practical applications, the authorized party may first request the authorized party to obtain the right to use the intellectual property, and then further apply for the authorized party to issue several digital assets anchoring single-use behavior in the chain based on the right to use. Specifically, the basic scheme may further include:

on one hand, the client of the authorized party calls an intelligent contract in the block chain network to execute the authorization request step: determining order information designated by an authorized party and triggering an event message containing the order information; the order information specifies intellectual property rights for which authorization to use is requested. The authorization request step precedes the asset application step described above.

On the other hand, after monitoring the event message containing the order information, at least one client of the authorized party calls an intelligent contract in the block chain network to execute an order confirmation step; the order confirmation step includes: creating an order based on the order information.

Similarly, if there are multiple authorized parties, the intelligent contract may need to collect signatures from a specified number of the multiple authorized parties before order confirmation steps can be performed.

Further, in practical applications, intellectual property rights correspond to a plurality of usage forms. For example, the multiple usage patterns corresponding to the copyright of a certain animation film may be multiple copyright materials (e.g., different animation characters); the multiple forms of use for a particular patent may include use during manufacture, use during sale, and the like.

Specifically, the step of the authorized party client invoking the execution of the intelligent contract in the blockchain network further comprises the step of using a morphology request. The use form requesting step precedes the asset application step. The usage form requesting step may be to determine usage form information designated by an authorized party and trigger an event message including the usage form information. Wherein the usage form information specifies at least one usage form. The step that at least one client of the authorized party can call the intelligent contract in the block chain network to execute after monitoring the event message containing the order information further comprises the step of using form confirmation. The usage form confirmation step may be to add the usage form information to the order.

Further, the usage form information may be added to the order in a case where the number of authorizer clients that invoke the smart contract in the blockchain network to perform the usage form confirmation step is not less than a specified number. In this context, only one intelligent contract may be deployed in a blockchain network, the intelligent contract being used to perform various steps.

In addition, more than one intelligent contract may be deployed in a blockchain network, with the intelligent contracts sharing the various steps of execution. In this case, when a certain intelligent contract executes a step, if the function of another intelligent contract is needed, another intelligent contract may be called in an inter-contract calling manner to perform corresponding processing, and a result returned by another intelligent contract is obtained.

In addition, in the case that the intelligent contract in the blockchain network is called to execute more than one step, the steps may be triggered to be executed by one call or triggered to be executed by multiple calls. For example, the authorizer client invokes an intelligent contract in the blockchain network to perform the issuing step and the associating step, and may submit a transaction invoking the intelligent contract to the blockchain network, so that the issuing step and the associating step are performed; or the authorizer client submits a transaction for calling the intelligent contract to the blockchain network first so as to execute the issuing step first, and then the authorizer client submits another transaction for calling the intelligent contract to the blockchain network so as to execute the association step.

In summary, in the description of the present specification, "invoking an intelligent contract in a blockchain network to perform at least one step" may include multiple cases, where the intelligent contract in the blockchain network is invoked to perform more than one step, where the intelligent contract in the blockchain network is invoked to perform one step, and so on.

On the basis of the basic scheme, a plurality of technical schemes which are more specific are explained in the following with the accompanying drawings.

Fig. 4 is a flowchart of a payment method for intellectual property use authorization provided in an embodiment of the present specification, including:

s400: the client end of the authorized party calls the intelligent contract in the block chain network to execute the authorization request step.

In the method shown in fig. 4, at least part of the down-link balance in the down-link account of the authorized party needs to be frozen in advance, and an up-link balance matching with the at least part of the down-link balance is created for the up-link account of the authorized party.

That is, at least a portion of the down-link balance in the authorized party's down-link account is mapped to the up-link balance of the authorized party's up-link account. This is done to give the virtual resource paid for by the authorized party to purchase intellectual property on the chain a corresponding real-life value.

In a specific implementation, the down-chain account manager may interface with the blockchain network manager, the authorized party requests the down-chain account manager to freeze at least part of down-chain balances in its down-chain account, then the down-chain account manager notifies the blockchain network manager, the blockchain network manager submits, to the blockchain network, a transaction for recharging to the up-chain account of the authorized party, and recharges the up-chain balance matched with the at least part of down-chain balance to the up-chain account of the authorized party.

The balance on the chain matched with at least part of balance under the chain can be equal, and can also be exchanged according to a certain proportion.

The data structure for the authorized party's on-chain account typically includes account identification, on-chain balance, anchor currency (e.g., RMB under the anchor chain), authorized party information (e.g., KYC information).

In addition, the authorizer may also have an on-chain account, but the authorizer's on-chain account does not directly receive transfers from the authorizer's on-chain account. In another specific implementation, a balance may not be set for the chain account of the authorizer, and the data structure of the chain account of the authorizer generally includes account identification and authorizer information (such as KYC information, license information, corporate information, and the like).

In the method shown in fig. 4, the step of performing the authorization request is: determining order information designated by an authorized party and triggering an event message containing the order information; the order information specifies intellectual property rights and usage fees for requesting authorization for use.

S402: and after monitoring the event message containing the order information, at least one client of the authorized party calls an intelligent contract in the block chain network to execute the order confirmation step and the order withdrawal step.

The order confirmation step is as follows: creating an order based on the order information and deducting the usage cost from the chain balance of the authorized party. Further, an order may be created based on the order information in a case where the number of authorizer clients that invoke an intelligent contract in the blockchain network to perform the order confirmation step is not less than a specified number.

The data structure of the order typically includes authorized party account information, usage fees, intellectual property identification, anchor currency, intellectual property usage restriction types (e.g., usage times restrictions, usage duration restrictions, etc.), status information (whether to present), and the like.

The order withdrawal step comprises the following steps: triggering an event message requesting presentation of the order. Further, the event message requesting to cash out the order may be triggered when the number of authorized party clients invoking the intelligent contract in the blockchain network to execute the order embodying step is not less than a specified number.

In addition, in the order withdrawal step, the state of the order can be changed from unretracted to withdrawn.

S404: and after determining that the order is requested to be presented, the down-link account management device unfreezes the down-link balance matched with the authorization cost in the down-link account of the authorized party, and transfers the down-link balance to the down-link account of the at least one authorized party.

When there are a plurality of authorized parties, the authorization fee is divided according to a certain proportion and then transferred to the linked accounts of the authorized parties.

In some embodiments of the method shown in fig. 4, the downlink account manager may own a client of the blockchain network, in which case, the downlink manager may directly monitor an event message requesting to withdraw the order from the blockchain network, and in response to the event message, unfreeze a downlink balance matching the authorization cost in the downlink account of the authorized party, and transfer the downlink balance to the downlink account of the at least one authorized party.

In other embodiments, the down-link account administrator does not own the clients of the blockchain network. In this case, the down-link manager device needs to interface with a client in the blockchain network (e.g., a manager client of the blockchain network). The method comprises the steps that the chain account management side equipment determines to request for the order to be presented, actually, the chain account management side equipment receives a notice sent by a client side of the block chain network according to an event message for monitoring the order to be presented, and determines to request for the order to be presented in response to the received notice.

By the method shown in fig. 4, an intellectual property right use authorization system is established based on a blockchain network, and an authorized party needs to map at least part of down-chain balances in own down-chain accounts to up-chain balances in up-chain accounts, and use the up-chain balances to purchase the right to use intellectual property rights. An authorized party can put forward an order request through an intelligent contract in a block chain network, wherein the order request carries order information and specifies intellectual property and use cost which are requested to be authorized to use. The intelligent contract triggers the order information in the form of event messages, each client of the authorized party of the intellectual property right decides whether to authorize or not after monitoring the order information (in the case of multiple authorized parties, each authorized party can call the intelligent contract to vote, and the intelligent contract counts out the voting result), if each authorized party decides to authorize, the intelligent contract can create an order according to the order information and deduct the use cost from the chain balance of the authorized party. In this way, the order of the authorized party for purchasing the usage right of the intellectual property right is stored in the chain, and the usage fee is automatically deducted by the intelligent contract and the paid usage fee is recorded in the order (which is equivalent to being locked in the order), so that the association between the usage fee paid by the authorized party and the intellectual property right authorization can be clarified.

Fig. 5 is a schematic flow chart of a digital asset circulation method corresponding to intellectual property rights, provided in the present specification, including:

s500: the authorized party client calls the intelligent contract in the block chain network to execute the asset application step.

The asset application steps in the method shown in fig. 5 are: determining application information designated by an authorized party and triggering an event message containing the application information; the application information specifies intellectual property rights authorized for use.

S502: and after monitoring the event message containing the application information, at least one client of the authorized party calls the intelligent contract in the blockchain network to execute the issuing step and the associating step.

The issuing steps in the method shown in fig. 5 are: and issuing at least one digital asset corresponding to the intellectual property. The correlation steps are as follows: an association between the authorized party and the at least one digital asset is created. Wherein the intellectual property right is legally used once in a manner that consumes one digital asset issued on the chain.

S504: and the authorized party client calls the intelligent contract in the block chain network to execute the asset transfer step.

The asset transfer steps in the method shown in fig. 5 are: determining at least one non-consumed digital asset that the authorized party specifies with which it is associated in a chain, and determining at least one transferee that the authorized party specifies; an association between the at least one unconsumed digital asset and the at least one transferee is created.

Further, in the method shown in fig. 5, the asset transfer step may further include: transferring the amount owned by the at least one transferee to the authorized party based on a transfer fee. That is, the transferee needs to pay a certain fee to the authorized party.

Further, the transfer fee may not be paid all the way to the authorized party, but in portions to the authorized party. Specifically, a portion of the transfer fee may be transferred to the authorizing party.

In addition, the transferee may further transfer the right of use of the intellectual property right. Specifically, any transferee client may invoke an intelligent contract in the blockchain network to perform the asset retransfer step: determining at least one non-consumed digital asset that the transferee specifies with which it is associated on the chain, and determining at least one retransfer that the transferee specifies; an associative relationship between the at least one unconsumed digital asset and the at least one retransferred party is created.

Accordingly, the asset re-transfer step may further comprise: transferring the amount owned by the at least one retransfer to the transferor based on a retransfer fee. Further, a portion of the amount of the re-transfer fee may be transferred to the authorizing party.

By establishing an intellectual property use authorization system based on a blockchain network by the method shown in fig. 5, anchoring a one-time use right for intellectual property under the chain to one digital asset on the chain, an authorized party needs to acquire an opportunity for legally using the one-time intellectual property in a manner of consuming one digital asset associated with the authorized party on the chain. The authorized party may further transfer one or more of the non-consumed digital assets (consumed digital assets invalid) associated with itself on the chain to the transferee.

Therefore, the circulation path of the use right of the intellectual property right can be clearly stored on the chain, and an authorized party can conveniently trace the use right.

In addition, intellectual property may be further transferred from the transferee to the transferee, creating a longer chain of circulation that will clearly evidence the chain.

Fig. 6 is a schematic flow chart of a digital asset application method corresponding to intellectual property rights, provided in the present specification, including:

s600: the authorized party client calls the intelligent contract in the block chain network to execute the asset application step.

The asset application step in the method of FIG. 6 includes: determining application information specified by an authorized party and triggering an event message containing the application information. The application information not only specifies intellectual property rights authorized to be used, but also specifies application use times N, wherein N is greater than 0.

The application use number may be defined as: using the intellectual property rights on a variable amount of application effort within an application domain; can also be defined as: the intellectual property right is used on an application outcome. An application result may refer to a product or a project.

S602: and after monitoring the event message containing the application information, at least one client of the authorized party calls the intelligent contract in the blockchain network to execute the issuing step and the associating step.

The issuing steps are as follows: and issuing N digital assets corresponding to the intellectual property. The correlation steps are as follows: creating an association between an authorized party and the N digital assets.

As such, an authorized party needs to legally use the intellectual property right once in a manner that consumes one digital asset with which it is associated on the chain.

In some embodiments, the triggering of the event message including the application information may specifically be: verifying whether the authorized party is eligible for authorization; and if the verification result representation passes, triggering the event message containing the application information, and if the verification result representation does not pass, refusing to trigger the event message containing the application information.

In some embodiments, in the issuing step, it may be verified whether the at least one authorizer client qualifies for authorization; and if the verification result is represented to pass, issuing the N digital assets corresponding to the intellectual property.

In some embodiments, the step of the authorizer client invoking execution of the intelligent contract in the blockchain network further comprises an authorization request step. The asset application step is preceded by an authorization request step comprising: determining order information designated by an authorized party and triggering an event message containing the order information; the order information specifies intellectual property rights and an upper limit M of the number of usage times for which authorization to use is requested.

Thus, the method shown in fig. 6 further includes that after the at least one authorizer client monitors the event message containing the order information, the client invokes an intelligent contract in the blockchain network to perform the order confirmation step: and creating an order corresponding to the order information. Further, the order corresponding to the order information may be created when the number of authorized clients invoking the intelligent contract in the blockchain network to perform the order confirmation step is not less than a specified number.

In addition, in some embodiments, the issuing of the N digital assets corresponding to the intellectual property right may specifically be: and if N is not more than M, issuing N digital assets corresponding to the intellectual property right, and taking M-N as M again. In this manner, it is ensured that the number of digital assets issued throughout the past time does not exceed the upper limit of usage times in the order agreed upon by the authorizing party and the authorizing party.

In addition, in the order confirmation step, the authorization cost may be transferred from the account of the authorized party to the account of the at least one authorization party, or the authorization cost may be transferred from the account of the authorized party to the account corresponding to the order.

By establishing an intellectual property use authorization system based on a blockchain network by the method shown in fig. 6, anchoring a one-time use right for intellectual property under the chain to one digital asset on the chain, an authorized party needs to acquire an opportunity for legally using the one-time intellectual property in a manner of consuming one digital asset related to the authorized party on the chain. In a specific implementation, an authorized party submits application information through an intelligent contract in a blockchain network, wherein the application information mainly specifies the intellectual property right which the authorized party wants to use and the number N of times the authorized party applies to use the intellectual property right. The authorizing party monitors the application information from the chain, calls an intelligent contract in the block chain network to issue N digital assets corresponding to the intellectual property, and creates an association relationship between the authorized party and the N digital assets.

In this way, chain credentialing is performed between the authorized party and the authorizing party for the number of times the intellectual property right is used (i.e. the limitation terms), and a one-time right to use the intellectual property right is anchored to one digital asset in the chain. If the authorized party and the authorizing party dispute the enforcement of the limit terms of the number of uses of the intellectual property right, the dispute may be resolved using the trusted record in the chain.

Fig. 7 is a schematic flow chart of another method for applying for digital assets corresponding to intellectual property rights, which is provided by the present specification, and includes:

s700: the authorized party client calls the intelligent contract in the block chain network to execute the asset application step.

The asset application step in the method of FIG. 7 includes: determining application information specified by an authorized party and triggering an event message containing the application information. Wherein the application information specifies intellectual property rights authorized to be used for a specified period, that is, not only the intellectual property rights requested to be authorized to be used but also a period for using the intellectual property rights.

S702: and after monitoring the event message containing the application information, at least one client of the authorized party calls the intelligent contract in the blockchain network to execute the issuing step and the associating step.

The issuing step in the method shown in fig. 7 includes: and issuing at least one digital asset corresponding to the intellectual property. Wherein the at least one digital asset is valid for a specified period and invalid outside the specified period.

The associating step in the method of fig. 7 includes: an association between the authorized party and the at least one digital asset is created.

In the method shown in FIG. 7, each digital asset issued has a validity period, which is the specified period described above. That is, the authorized party can only legally use the intellectual property right once within a specified period of time in a manner that consumes a valid digital asset with which it is associated on the chain, leaving a legal use record on the chain.

In some embodiments, triggering the event message including the application information may specifically include: verifying whether the authorized party is eligible for authorization; and if the verification result representation passes, triggering the event message containing the application information, and if the verification result representation does not pass, refusing to trigger the event message containing the application information.

In some embodiments, issuing N digital assets corresponding to the intellectual property right may specifically include: verifying whether the at least one authorizer client is eligible for authorization; and if the verification result is passed, issuing at least one digital asset corresponding to the intellectual property.

In some embodiments, issuing at least one digital asset corresponding to the intellectual property right may specifically include: and issuing at least one digital asset corresponding to the intellectual property right under the condition that the number of authorized party clients for calling the intelligent contract in the blockchain network to execute the issuing step is not less than the specified number.

In some embodiments, the step of the client of the authorized party calling the intelligent contract in the blockchain network to execute further comprises the step of authorizing the request; the authorization request step precedes the asset application step, and may include: determining order information designated by an authorized party and triggering an event message containing the order information; the order information specifies an intellectual property right for which authorization to use is requested and a specified period for which authorization to use the intellectual property right is requested.

Correspondingly, the method shown in fig. 7 further includes: after monitoring the event message containing the order information, at least one client of the authorized party calls an intelligent contract in the blockchain network to execute the order confirmation step: and creating an order corresponding to the order information.

In some embodiments, creating the order corresponding to the order information may include: and under the condition that the number of authorized party clients for executing the order confirmation step by calling the intelligent contract in the block chain network is not less than the specified number, creating the order corresponding to the order information.

In some embodiments, issuing at least one digital asset corresponding to the intellectual property right may include: and issuing at least one digital asset corresponding to the intellectual property right under the condition that the current time is not later than the corresponding termination time of the specified period.

By establishing an intellectual property use authorization system based on a blockchain network by the method shown in fig. 7, anchoring a one-time use right for intellectual property under the chain to one digital asset on the chain, an authorized party needs to acquire an opportunity for legally using the one-time intellectual property in a manner of consuming one digital asset related to the authorized party on the chain. In a specific implementation, an authorized party submits application information through an intelligent contract in a blockchain network, wherein the application information mainly specifies intellectual property rights which the authorized party wants to use and the period of time for which the authorized party applies to use the intellectual property rights. The authorizing party monitors the application information from the chain, calls an intelligent contract in the block chain network to issue at least one digital asset corresponding to the intellectual property, each digital asset has a valid period in the use period, and creates an association relationship between the authorized party and the at least one digital asset.

In this way, chain credentialing is performed between the authorized party and the authorizing party for the agreement (i.e., the limitation term) during the usage of the intellectual property right, and a one-time right to use the intellectual property right is anchored to one digital asset in the chain, and the authorized party needs to consume one valid digital asset in the chain every time the intellectual property right is legally used, so that the chain can credentitle each legal use of the intellectual property right by the authorized party. If the authorized party disputes with the authorizing party regarding the implementation of the terms of the restrictions during the use of the intellectual property, the dispute may be resolved using the trusted record on the chain.

The present specification also provides a method of generating digital assets, the method of generating being implemented based on an intelligent contract that performs issuing steps, comprising:

In some embodiments, parsing the data structure to obtain the asset base code and the unique index code may include: and verifying the authorized party signature and the authorized party signature in the data structure, and analyzing the data structure to obtain the asset basic code and the unique index code if the authorized party signature and the authorized party signature in the data structure pass verification.

In some embodiments, parsing the data structure to obtain the asset base code and the unique index code may include: and decrypting the encrypted asset code in the data structure by using a management decryption key corresponding to the intelligent contract executing the issuing step to obtain the asset basic code and the unique index code.

In some embodiments, if it is determined that the verification is passed, the digital asset may be placed in a state that characterizes the verification. In addition, if the verification is determined to pass, the number of times of verification corresponding to the digital asset may be increased by 1.

The present specification also correspondingly provides a digital asset verification method (applicable to the embodiment with the service life as a limiting term), which is implemented based on an intelligent contract that performs issuing steps, and comprises the following steps:

1. acquiring a data structure of a digital asset to be verified;

2. analyzing the data structure to obtain an asset basic code;

3. judging whether the recorded legal asset basic codes comprise asset basic codes obtained by analysis or not; if the judgment result is yes, the verification is determined to be passed; and if the judgment result is negative, determining that the verification is not passed.

The specification provides an intellectual property right application method based on digital assets, which is suitable for an embodiment taking the number of times of use as a limit term, and the application method specifically comprises the following steps: the authorized party client invokes an intelligent contract in the blockchain network to perform the asset consumption step. The asset consumption step comprises: acquiring a use application submitted by an authorized party for realizing one-time intellectual property use behavior under a chain; placing an unconsumed digital asset associated with the authorized party in a state that characterizes the consumption and triggering an event message that permits the use of the intellectual property right. And the client of the authorized party informs the authorized party after monitoring the event message which permits the intellectual property use behavior.

The specification provides an intellectual property use application method based on digital assets, which is suitable for an embodiment taking a service life as a limiting term, and the use application method specifically comprises the following steps: the authorized party client invokes an intelligent contract in the blockchain network to perform the asset consumption step. The asset consumption step comprises: acquiring a use application submitted by an authorized party for realizing one-time intellectual property use behavior under a chain; placing an unconsumed and valid digital asset associated with the authorized party in a state that characterizes the consumption and triggering an event message that permits the use of the intellectual property right. And the client of the authorized party informs the authorized party after monitoring the event message which permits the intellectual property use behavior.

Fig. 8 is a flowchart of a method for authorizing manufacturing of an intellectual property product, which includes:

s800: the authorized party client calls the intelligent contract in the block chain network to execute the asset application step.

The asset application step in the method of FIG. 8 includes: determining application information specified by an authorized party and triggering an event message containing the application information. The application information specifies intellectual property rights authorized for use.

S802: and after monitoring the event message containing the application information, at least one client of the authorized party calls an intelligent contract in the blockchain network to execute a first issuing step and a first associating step.

The first sending step is as follows: and issuing N property digital assets corresponding to the intellectual property. The first associating step includes: an association between the authorized party and the N title digital assets is created.

S804: the authorized party client calls the intelligent contract in the blockchain network to execute the second issuing step and the second associating step.

The second issuing step is: n product digital assets are issued that correspond one-to-one with the N base products. The second association step is: creating a one-to-one association between the N title digital assets and the N product digital assets.

It should be noted that the second issuing step may be performed prior to the first associating step.

The basic product is a foundation for manufacturing the intellectual property product, and can be regarded as an intellectual property product obtained by superposing the basic product on the one-time use behavior of the intellectual property. For example, a coffee cup is a basic product, and after an animated character is printed on the coffee cup, an intellectual property product is obtained.

By the method shown in fig. 8, the authorized party manufactures an intellectual property product based on the base product corresponding to the product digital asset associated with the property digital asset in a manner of consuming the property digital asset associated with the authorized party on the chain.

In the method shown in fig. 8, when the authorized party manufactures the product using intellectual property, two limitations are needed: 1. manufacturing an intellectual property product requiring consumption of an associated property digital asset; 2. when manufacturing the intellectual property product, it is necessary to manufacture the product using the basic product corresponding to the product digital asset associated with the consumed digital asset. In this way, each intellectual property product manufactured by the authorized party is mapped to the association relationship between a group of product digital assets and property digital assets on the chain, and the authorized party controls the product manufacturing behavior of the authorized party based on the association relationship on the chain, so that the product manufacturing behavior of the authorized party meets the convention, and the authorized party is difficult to abuse the intellectual property manufacturing product.

Continuing with the method of FIG. 8, the base product can belong to a physical base product (e.g., coffee cup) or a virtual base product (e.g., a membership card in a cafe, where the code is a virtual product).

Further, in some embodiments, an intelligent contract in the blockchain network may be invoked to perform a third issuing step: based on each set of associated title digital assets and product digital assets, a corresponding portfolio digital asset is generated and issued. In practical application, if the basic product belongs to an entity product, an authorized party can print or paste the identifier of the combined digital asset on the basic product to obtain an intellectual property product; if the base product belongs to the virtual product, the authorized party can write the identifier of the combined digital asset into the code of the base product to obtain the intellectual property product.

Further, the client may be an authorized party client or the at least one authorized party client, and the intelligent contract in the blockchain network is invoked to perform a third issuing step.

In some embodiments, the data structure for any portfolio digital asset may include: a combination of a corresponding property digital asset, a corresponding product digital asset, an authorized party signature, a blockchain network signature.

The authorized party signature is obtained by using a private key of the authorized party to sign the property digital asset and the product digital asset; the blockchain network signature is obtained by using an administrator public key of the blockchain network to sign the property year digital asset and the product digital asset.

Accordingly, for any portfolio digital asset, the portfolio digital asset is validated by:

verifying the property digital asset, the product digital asset, the authorized party signature and the blockchain network signature in the data structure of the combined digital asset respectively; if all the verifications are passed, determining that the combined digital asset passes the verification; if any verification fails, the combined digital asset is determined to have failed verification.

The technical solutions provided in this specification are exemplified by taking the intellectual property as an IP brand, the digital asset as an NFT, the authorizing party as a copyright party of the IP brand, and the authorized party as an IP merchant, and it should be understood that this should not be construed as limiting the scope of the description.

Fig. 9 is a schematic diagram of an IP brand use authorization system based on a block chain provided in the present specification. As shown in fig. 9, an IP authorized transaction intelligent contract is deployed in the blockchain network, and a plurality of IP merchants (IP merchant A, IP merchant C) and a plurality of IP copyright parties (IP copyright party B, IP copyright party D) can conduct IP authorized transactions through the blockchain network. It should be noted that the IP brand issued by the copyright owner to the intelligent contract on the chain may be represented using the subject matter of the copyrighted work owned by the copyright owner.

Fig. 10 is a flow chart of block chain based IP brand usage authorization provided in the present specification. As shown in FIG. 10, IP Merchant A first requests to purchase IP brand usage rights and specifies an upper limit of 1000 NFTs (i.e., 1000 uses at most). The copyright party B (actually corresponding to a plurality of specific copyright parties) needs to make a multiparty signature confirmation on the contract (i.e. the order information), create an order on the chain, and the IP merchant a can complete the payment of the usage fee (the usage fee is locked into the order) at the same time. Then, the IP merchant a can further specify a certain material (e.g., a certain animated character) under the IP brand as a specific usage form using the IP brand, and the copyright party B continues the signature verification. Then, IP merchant a may apply for copyright party B to publish 1000 NFTs in the chain, each NFT corresponding to a use opportunity, and copyright party B may sign the confirmation, generate and publish 1000 NFTs in the chain.

Fig. 11 is a schematic flowchart of an IP merchant charging an up-chain account based on an down-chain account according to the present specification. As shown in fig. 11, the bank/financial institution is the down-link account manager, and the IP authorization chain (i.e., the blockchain network described herein) funds gateway is the manager interfacing with the blockchain network and is responsible for interfacing with the down-link account manager.

FIG. 12 is a flow diagram of an IP merchant purchasing IP brand usage rights over a chain as provided by the present specification. As shown in fig. 12, the IP merchant a places an order through the intelligent contract on the chain, which results in the deduction of the account on the chain of the IP merchant a, the IP copyright side B confirms the authorization, triggers the intelligent contract on the chain to create an order, and locks the usage charge in the order. The IP copyright side B can call a contract to execute an order cashing step by taking the order as granularity, and cashing the funds locked in the order to the own linked account in the bank. Every withdrawal of the IP copyright side B is well documented, the account on the chain of the IP copyright side B does not have balance, the order locks funds, and the order is regarded as spending after being withdrawn, so that the scheme takes the advantages of the account model and the UXTO model into account.

Fig. 13 is a schematic flow chart of a link abstraction of an IP copyright owner provided in this specification. As shown in fig. 13, the invocation of the contract execution order cashing step by the IP copyright side B results in the order status changing to cashed, and the contract triggers an event message, equivalent to mapping out the amount locked in the order. The funds of the chain-down account of the IP copyright party B are increased, and the funds of the chain-down account of the IP merchant A are unfrozen and deducted.

Fig. 14 and 15 are schematic diagrams of NFT flow provided in the present specification. The NFT code authorized by each brand can be converted into a two-dimensional code to be printed on a real object (such as a water cup and clothes), and the real object can be circulated for the second time.

Fig. 16 is a schematic diagram of the NFT secondary flow provided in this specification. As shown in fig. 16, after the IP copyright party B authorizes the IP brand to the IP merchant a for use, the IP merchant a may further authorize the IP brand to the IP merchant C for use, resulting in a second circulation, the cost paid by the IP merchant C to the IP merchant a needs to be billed based on the chain of intelligent contracts, and a portion of the funds will be transferred to the IP copyright party B.
