Description

Digital asset circulation method corresponding to intellectual property

Technical Field

One or more embodiments of the present disclosure relate to the field of terminal technologies, and in particular, to a digital asset circulation method corresponding to intellectual property rights.

Background

A party possessing intellectual property rights (an authorized party) may authorize a person or an organization (an authorized party) to use the intellectual property rights in practice. For example, a party possessing cartoon copyrights may authorize a coffee cup manufacturer to print a cartoon character in a cartoon on a coffee cup that it makes. For another example, a party possessing a drug patent may authorize a pharmaceutical factory to produce a corresponding drug.

In practice, authorized parties sometimes transfer at least some of the usage rights of the intellectual property rights further to other individuals or organizations (transferees), however, in such complex transfer relationships, there are trust issues between the authorized party, and the transferee.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to 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 aspects of one or more embodiments of the present description as detailed in the accompanying claims.

It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.

Currently, a party possessing intellectual property rights (an authorizer) may authorize a person or an organization (an authorized party) to use the intellectual property rights in practice. For example, a party possessing cartoon copyrights may authorize a coffee cup manufacturer to print a cartoon character in a cartoon on a coffee cup that it makes. For another example, a party possessing a drug patent may authorize a pharmaceutical factory to produce a corresponding drug.

In practice, there are several trust challenges in authorizing an intellectual property right to an authorized party for use by an authorized party:

1. the authorizer often achieves the limitation terms related to the use of the intellectual property with the authorizer before the use of the intellectual property is authorized to the authorizer, and the limitation terms can be used for limiting the use times of the intellectual property by the authorizer or limiting the use time of the intellectual property by the authorizer.

However, it is difficult for the authorized party to trace back the implementation of the terms of the restrictions. The authorized party may not adhere to the terms of the restrictions, overuse the intellectual property or continue to use the intellectual property outside of the period of use. Even if the authorized party knows that there is a behavior that does not adhere to the restriction terms, because the intellectual property is intangible and repeatable, it is difficult for the authorized party to specifically distinguish 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 adhere to the restriction terms.

2. The authorized party often needs to pay the authorizing party for the use of the intellectual property. However, since intellectual property rights are intangible, it is difficult in practice to explicitly relate the payment behavior of an authorized party to the intellectual property right itself. That is, even if the authorized party receives a funds from the authorized party, the authorized party may not acknowledge that the funds are the use fee of the intellectual property rights and repudiate the funds.

3. The authorized party may further transfer at least part of the intellectual property rights to other individuals or institutions (transferees), however, in such complex circulation relationships, it is difficult for the authorized party to trace the circulation path, and control over the own intellectual property rights is lost.

4. In practice, products manufactured using intellectual property are often referred to as intellectual property products, and an authorized party often makes a contract with an authorized party in advance regarding what intellectual property products can be manufactured, and the authorized party wishes to trace back which intellectual property products the authorized party manufactured using the intellectual property. Therefore, how to prevent the authorized party from abusing the intellectual property rights for product manufacturing is a problem to be solved.

Aiming at the trust problems in the 4 aspects, the specification respectively provides a plurality of technical schemes realized based on the block chain technology. It should be noted that, these technical schemes may be arbitrarily combined into new technical schemes, and the combined new technical schemes should be within the scope described in the present specification.

Blockchain techniques are described herein.

Blockchains are generally divided into three types: public chains (Public Blockchain), private chains (Private Blockchain) and federated chains (Consortium Blockchain). In addition, there are many types of combinations, such as different combinations of private chain+federation chain, federation chain+public chain, and the like. Among them, the highest degree of decentralization is the public chain. The public chain is represented by bitcoin and ethernet, and participants joining the public chain can read data records on the chain, participate in transactions, compete for accounting rights of new blocks, and the like. Moreover, each participant (i.e., node) is free to join and leave the network and perform related operations. The private chain is the opposite, the write rights of the network are controlled by an organization or organization, and the data read rights are specified by the organization. In short, the private chain may be a weakly centralized system with few and strict restrictions on participating nodes. This type of blockchain is more suitable for use within a particular organization. The alliance chain is a block chain between public and private chains, and can realize 'partial decentralization'. Each node in the federation chain typically has an entity organization or organization corresponding thereto; participants join the network by authorization and form a benefit-related federation, collectively maintaining blockchain operation.

Whether public, private, or federation, it is possible to provide the functionality of a smart contract. Intelligent contracts on blockchains are contracts on blockchain systems that can be executed by transaction triggers. The smart contracts may be defined in the form of codes.

Taking the ethernet as an example, support users create and invoke some complex logic in the ethernet network, which is the biggest challenge for ethernet to distinguish from the bitcoin blockchain technology. At the heart of the ethernet as a programmable blockchain is an Ethernet Virtual Machine (EVM), which can be run by each ethernet node. The EVM is a graphics-complete virtual machine, meaning that various complex logic can be implemented by it. The user's issuing and invoking of the smart contract in the ethernet is running on the EVM. In practice, the virtual machine runs directly on virtual machine code (virtual machine bytecode, hereinafter "bytecode"). The intelligent contracts deployed on the blockchain may be in the form of bytecodes.

For example, as shown in fig. 1, bob sends a transaction containing information to create a smart contract to the ethernet network, the EVM of node 1 may execute the transaction and generate the corresponding contract instance. "0x6f8ae93 …" in fig. 1 represents the address of this contract, the data field of the transaction may hold byte code, and the to field of the transaction is empty. After agreement is reached between nodes through the consensus mechanism, this contract is successfully created and can be invoked in a subsequent process. After the contract is created, a contract account corresponding to the intelligent contract appears on the blockchain, and the contract account is stored with a specific address. The behavior of the smart contract is controlled by the contract code. In other words, the smart contract causes a virtual account to be generated on the blockchain that includes a contract code and an account store (Storage).

Still taking the ethernet as an example, as shown in fig. 2, bob sends a transaction for invoking a smart contract to the ethernet network, the EVM of a node may execute the transaction and generate the corresponding contract instance. In fig. 2, the from field of the transaction is the address of the account of the transaction initiator (i.e. Bob), the "0x6f8ae93 …" in the to field represents the address of the called smart contract, the value field is the value of the ethernet in the ethernet, and the data field of the transaction holds the method and parameters for calling the smart contract. The value of the policy may change after invoking the smart contract. Subsequently, a client may view the current value of the policy 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, all execution records and data are stored on the blockchain, so that when the transaction is completed, transaction credentials which cannot be tampered and cannot be lost are stored on the blockchain.

A schematic diagram of creating a smart contract and invoking a smart contract is shown in fig. 3. To create an intelligent contract in the ethernet, the intelligent contract needs to be written, changed into byte codes, deployed to a blockchain and the like. The intelligent contract is called in the Ethernet, a transaction pointing to the intelligent contract address is initiated, and intelligent contract codes are distributed and run in the virtual machine of each node in the Ethernet network.

It should be noted that, in addition to the smart contracts that can be created by the user, the smart contracts can also be set by the system in the creation block. Such contracts are commonly referred to as an opening contract. In general, some blockchain networks may be configured with data structures, parameters, attributes, and methods in the creating contracts. In addition, an account with system administrator rights may create a system level contract, or modify a system level contract (simply referred to as a system contract). In addition, different blockchain networks may employ various virtual machines in addition to the EVM in the ethernet, which is not limited herein.

After executing a transaction invoking the 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 result of contract execution can be obtained by querying the receipt of the transaction. The contract execution result may be represented as an event (event) in a receipt. The messaging mechanism may implement messaging through events in the receipt to trigger a blockchain node or node device deploying the blockchain node to perform a corresponding process.

The structure of the event may be, for example:

Event：

[topic][data]

......

in the above examples, the number of events may be one or more; wherein each event includes fields such as a theme (topic) and data (data), respectively. The blockchain node or the node device deploying the blockchain node may perform a preset process by listening to the topic of the event, thereby performing a preset process in case of listening to the predefined topic, or read the related content from the data field of the corresponding event, and may perform a preset process based on the read content.

Blockchain technology differs from one of the decentralized features of conventional technology in that accounting is performed on individual nodes, otherwise known as distributed accounting, rather than conventional centralized accounting. The blockchain system is to be a hard-to-break, public, untampered, decentralised, honest and trusted system for data records, and needs to be secure, clear and irreversible for distributed data records in as short a time as possible. In different types of blockchain networks, in order to keep account books consistent among the nodes of each record account book, a consensus algorithm is generally adopted to ensure that the above-mentioned consensus mechanism is adopted. After a node (e.g., a unique node) creates a block, if the created block is approved by other nodes, the other nodes record the same block. The process that the generated block is approved by other nodes is a consensus mechanism. The consensus mechanism is a mechanism that the blockchain node achieves the consensus of the whole network about the blockinformation (or blockdata), and can ensure that the latest block is accurately added to the blockchain. The consensus mechanisms of the current mainstream include: proof of Work (POW), proof of equity (POS), proof of commission (Delegated Proof of Stake, DPOS), practical bayer fault tolerance (Practical Byzantine Fault Tolerance, PBFT) algorithm, honeybadgenbft algorithm, etc.

Some concepts will be described herein as will be used later.

Intellectual property rights: typically including copyrights, patent rights, trademark rights, service marks, vendor names, origin names, plant new species rights, integrated circuit layout design proprietary rights, and the like. Intellectual property has intangibility and reusability, and all the intellectual property can authorize other people to use the intellectual property.

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

The authorized party: and the party with the intellectual property right authorization relationship with the authorizer directly cooperates with the authorizer for using and authorizing the intellectual property right.

The transferee: at least part of the use rights of the intellectual property rights are secondarily streamed from the authorized party to the party.

The re-transferee: at least part of the intellectual property rights are streamed again from the transferee to the party. It will be appreciated that the usage rights for intellectual property may be continuously circulated a number of times to form a circulation chain.

Client side: refers to clients of a blockchain network, also known as blockchain clients. The blockchain client may or may not be a node of a blockchain network (as in the case of a public chain network). The blockchain client may initiate a transaction to the blockchain network, invoking the intelligent contract in the blockchain network through the transaction, such that the blockchain network performs the business-related steps of the transaction request based on the code logic described in the invoked intelligent contract. The client of the authorized party is a client of the authorized party, the client of the transfered party is a client of the transfered party, and the client of the transfered party is a client of the transfered party once.

Digital asset: is a data structure defined by intelligent contracts in a blockchain network based on some digital asset protocol. The digital assets on the chain are mappings of objects under the chain on the chain, the digital assets having uniqueness and an anchoring relationship with the objects under the chain. Alternatively, digital assets may be defined using the digital asset protocol (ERC 721), which is currently popular, and such digital assets are commonly referred to as Non-homogeneous tokens (NFTs). In addition, other digital asset protocols may be used to define digital assets.

Several technical solutions implemented based on blockchain technology are described below.

The present specification first provides an intellectual property rights usage authorization infrastructure, as follows:

in one aspect, an authorized party client invokes an intelligent contract in a blockchain network to perform asset application steps: determining application information appointed by an authorized party, and triggering event information containing the application information; the application information specifies the intellectual property rights that are authorized for use.

On the other hand, after at least one authorized party client monitors the event message containing the application information, calling an intelligent contract in the blockchain 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 includes: an association between the authorized party and the at least one digital asset is created.

Thus, a principal under the chain having access to the intellectual property (either an authorized party or an transferee to whom the authorized party transfers at least part of the intellectual property's usage rights) needs to use the intellectual property once legally in a manner that consumes one digital asset issued on the chain, leaving a record on the chain of the legal use of the intellectual property once, facilitating traceability by the authorized party. Specifically, the authorized party may initiate a transaction to the blockchain for consuming one or more digital assets, the transaction invoking an intelligent contract to place the digital asset specified by the transaction in a consumed state from an unconsumed state after determining that the digital asset specified by the transaction has a chain-link association with the authorized party and has not been consumed, indicating that the intellectual property usage opportunity anchored by the digital asset has been achieved.

By "legal use" is meant that the usage behavior complies with the usage restriction terms agreed upon by the authorized party and the authorizing party. In practice, if the authorized party finds that the one-time use behavior of the authorized party is not recorded on the chain by consuming a digital asset, the one-time use behavior may be deemed illegal.

As used herein, "consuming" digital assets is understood to mean that each digital asset can only be called once, and once called once by its associated principal, is equivalent to being "consumed" and no longer valid.

In practice, multiple authorizers may share the same intellectual property, in which case the multiple authorizers are required to make decisions based on some decision mechanism in determining whether to authorize the intellectual property to the authorized party. For example, a vote may be made between the plurality of authorized parties, each of which submits a signature of the vote to the smart contract, which performs statistics to determine whether to authorize. That is, the smart contract needs to gather signatures of a specified number of the plurality of authorizers before the issuing step and the associating step can be performed.

Further, in actual application, the authorized party may first request the authorized party to obtain the right to use the intellectual property rights, and then further apply the authorized party to issue a number of digital assets anchoring the single use behavior on the chain based on the right to use. Specifically, the above basic scheme may further include:

in one aspect, an authorized party client invokes an intelligent contract in a blockchain network to perform an authorization request step: determining order information designated by an authorized party, and triggering event messages containing the order information; the order information specifies the intellectual property rights requested for authorized use. The authorization request step precedes the asset application step described above.

On the other hand, after at least one authorized party client monitors the event message containing the order information, calling an intelligent contract in the blockchain network to execute an order confirmation step; the order confirmation step includes: an order is created based on the order information.

Similarly, if there are multiple authorizers, the intelligent contract needs to gather signatures of a specified number of the plurality of authorizers before the order validation step can be performed.

Further, in practical applications, intellectual property corresponds to various usage forms. For example, the plurality of usage forms corresponding to the copyrights of a certain animation film may be a plurality of copyrighted materials (e.g., different animation characters); the various usage patterns corresponding to a particular patent right may include in-production usage, in-sales usage, etc.

Specifically, the step of the authorized party client invoking intelligent contract execution in the blockchain network further includes the step of using the morphology request. The usage modality requesting step precedes the asset application step. The usage pattern request step may be to determine usage pattern information specified by the authorized party and trigger an event message containing the usage pattern information. Wherein the usage pattern information specifies at least one usage pattern. The step of at least one authorizer client, after monitoring for an event message containing the order information, may invoke execution of a smart contract in the blockchain network further includes using a morphology validation step. The usage pattern confirmation step may be to add the usage pattern information to the order.

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

In addition, more than one intelligent contract may be deployed in a blockchain network that shares execution of various steps. In this case, when a certain smart contract performs the step, if the function of other smart contracts is needed, other smart contracts can be called to perform corresponding processing in a calling manner between contracts, and the results returned by other smart contracts are obtained.

In addition, where more than one step is performed by invoking an intelligent contract in a blockchain network, the steps may be performed by invoking the trigger once or multiple times. For example, the authorizer client invoking the intelligent contract in the blockchain network to perform the issuing step and the associating step may be that the authorizer client submits a transaction invoking the intelligent contract to the blockchain network so that both the issuing step and the associating step are performed; or the authorizing party client submits a transaction for calling the intelligent contract to the blockchain network firstly, so that the issuing step is executed firstly, and then the authorizing party client submits another transaction for calling the intelligent contract to the blockchain network, so that the association step is executed again.

In summary, throughout the description herein, "invoking a smart contract in a blockchain network to perform at least one step" may include a variety of situations, may invoke more than one step in a blockchain network, may invoke more than one smart contract in a blockchain network to perform one step, may invoke more than one smart contract in a blockchain network to perform more than one step, may invoke one smart contract in a blockchain network to perform one step, and so on.

On the basis of the basic scheme, a plurality of more specific technical schemes are described below with reference to the accompanying drawings.

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

s400: the authorized party client invokes the intelligent contract in the blockchain network to perform the authorization request step.

In the method shown in fig. 4, it is necessary to pre-freeze at least part of the under-link balance in the under-link account of the authorized party, and create an on-link balance for the on-link account of the authorized party that matches the at least part of the under-link balance.

That is, at least a portion of the under-link balance in the under-link account of the authorized party is mapped to the on-link balance of the on-link account of the authorized party. The purpose of this is to have the virtual resources paid by the authorized party to purchase intellectual property rights on the chain have a corresponding real value.

In a specific implementation, the under-chain account manager may interface with the blockchain network manager, the authorized party requests the under-chain account manager to freeze at least a portion of the under-chain balance in its under-chain account, and then the under-chain account manager notifies the blockchain network manager that the blockchain network manager submits a transaction to the blockchain network for recharging the on-chain account of the authorized party, and the on-chain balance matched with the at least a portion of the under-chain balance is recharged to the on-chain account of the authorized party.

The balance on the chain, which is matched with at least part of the balance under the chain, can be equal in amount or can be exchanged according to a certain proportion.

The data structure of 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 have an on-chain account, but the authorizer's on-chain account does not directly receive a transfer of the authorizer's on-chain account. In another embodiment, the balance may not be set for the on-chain account of the authorizer, which typically includes account identification, authorizer information (e.g., KYC information, license information, legal person information, etc.).

In the method shown in fig. 4, the authorization request step is performed as follows: determining order information designated by an authorized party, and triggering event messages containing the order information; the order information specifies intellectual property rights and usage fees for which authorization is requested.

S402: and after the at least one authorized party client monitors the event message containing the order information, calling an intelligent contract in the blockchain network to execute an order confirmation step and an order proposal step.

The order confirmation step is as follows: creating an order based on the order information and deducting the usage charge from the on-chain balance of the authorized party. Further, an order may be created based on the order information if the number of authorizer clients invoking the 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 currencies, types of intellectual property usage restrictions (e.g., usage times restrictions, usage period restrictions, etc.), status information (whether or not to present), and the like.

The order proposal steps are as follows: triggering an event message requesting that the order be placed. Further, an event message requesting that the order be placed may be triggered if the number of authorizer clients invoking the intelligent contract in the blockchain network to perform the order-placement step is not less than a specified number.

In addition, in the order proposing step, the state of the order can be changed from unrepresentative to proposed.

S404: after determining that the order is requested to be placed, the under-chain account manager device thaws the under-chain balance matched with the authorized expense in the under-chain account of the authorized party, and transfers the under-chain balance to the under-chain account of the at least one authorized party.

When there are a plurality of authorizers, the authorized fees are generally divided according to a certain proportion and then transferred to the under-chain accounts of the authorizers respectively.

In some embodiments of the method of fig. 4, the under-chain account manager device may have a client of the blockchain network, in which case the under-chain manager device may directly monitor from the blockchain network for an event message requesting that the order be placed, and in response to the event message, defrost the under-chain balance in the under-chain account of the authorized party that matches the authorization cost, and transfer to the under-chain account of the at least one authorized party.

In other embodiments, the under-chain account manager does not own clients of the blockchain network. In this case, the under-chain manager device needs to interface with clients in the blockchain network (e.g., manager clients of the blockchain network). The link-down account manager device determines that the order is requested to be placed, in fact, the link-down account manager device receives a notification sent by a client of the blockchain network according to an event message that the client monitors that the order is requested to be placed, and determines that the order is requested to be placed in response to the received notification.

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 the under-chain balance in the own under-chain account to the on-chain balance in the on-chain account, and purchase the right to use the intellectual property right using the on-chain balance. The authorized party may make an order request through an intelligent contract in the blockchain network, the order request carrying order information specifying the intellectual property rights and usage fees for which authorization is requested. The intelligent contract triggers the order information in the form of event information, and after each authority client of the intellectual property monitors the order information, the client decides whether to authorize (in the case of a plurality of authorities, each authority can call the intelligent contract to vote, the intelligent contract counts voting results), and if each authority decides to authorize, the intelligent contract can create an order according to the order information and deduct the use expense from the balance on the chain of the authorized party. In this way, the order of the authorized party for the use of the intellectual property rights is verified on the chain, and the use fee is automatically deducted by the intelligent contract and the paid use fee is recorded in the order (corresponding to being locked in the order), so that the association between the use fee paid by the authorized party and the intellectual property rights can be clarified.

The authorizers may perform the order raising step at any time by means of intelligent contracts in the blockchain network, i.e. raising the usage charges locked in the order, triggering the transfer of the usage charges from the under-chain accounts of the authorizers to the under-chain accounts of the authorizers. Therefore, the order proposal record of the authorized party can be stored in the chain and cannot be repudiated, and meanwhile, the financial supervision and management institution can conveniently supervise the account entering of the authorized party by taking the order proposal record as a trusted basis.

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

s500: the authorized party client invokes the intelligent contract in the blockchain network to perform the asset application step.

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

S502: at least one authorizer client, after monitoring the event message containing the application information, invokes a smart contract in the blockchain network to perform 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 association 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: the authorized party client invokes a smart contract in the blockchain network to perform an asset transfer step.

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

In addition, 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 the transfer fees. That is, the transferee needs to pay a certain fee to the authorized party.

Further, the transfer fee may not be paid to the authorized party at all, but may be divided into a portion of the transfer fee. Specifically, a partial amount of the transfer fee may be transferred to the authorized party.

In addition, the transferee may further transfer the right to use the intellectual property right. Specifically, any transferee client may invoke a smart contract in the blockchain network to perform an asset re-transfer step: determining at least one unconsumed digital asset designated by the transferee that is associated with the chain, and determining at least one transferee designated by the transferee; an association is created between the at least one unconsumed digital asset and the at least one reassigned party.

Accordingly, the asset re-transfer step may further include: the amount owned by the at least one transferee is transferred to the transferor based on the transfer fees. Further, a portion of the amount of the re-transfer fee may be transferred to the authorized party.

By the method shown in fig. 5, an intellectual property right usage authorization system is established based on a blockchain network, one-time usage rights for intellectual property right under the chain are anchored to one digital asset on the chain, and an authorized party needs to acquire opportunities for legal one-time usage of the intellectual property right in a way of consuming one digital asset associated with the authorized party on the chain. The authorized party may further transfer one or more unconsumed digital assets (spent digital assets being inactive) associated with itself on the chain to the transferee.

In addition, intellectual property may be further diverted from the transferee to the re-transferee, creating a longer chain of circulation that clearly manifests itself in the chain.

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

S600: the authorized party client invokes the intelligent contract in the blockchain network to perform the asset application step.

The asset application steps in the method of fig. 6 include: and determining application information designated by the authorized party, and triggering event messages containing the application information. The application information not only specifies intellectual property rights that are authorized to be used, but also specifies that the application use times N, N is greater than 0.

The number of applications may be defined as: using the intellectual property on an application effort of varying amount within an application domain; can also be defined as: the intellectual property right is used on an application result. Wherein an application outcome may refer to a product or an item.

S602: at least one authorizer client, after monitoring the event message containing the application information, invokes a smart contract in the blockchain network to perform the issuing step and the associating step.

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

As such, an authorized party needs to legally use the intellectual property once in a manner that consumes one of its digital assets associated on the chain.

In some embodiments, the triggering event message including the application information may specifically be: checking whether the authorized party is authorized; 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 is authorized; and if the verification result representation passes, issuing N digital assets corresponding to the intellectual property rights.

In some embodiments, the step of the authorized party client invoking intelligent contract execution in the blockchain network further comprises an authorization request step. An authorization request step precedes the asset application step, the authorization request step comprising: determining order information designated by an authorized party, and triggering event messages containing the order information; the order information specifies the intellectual property rights requested for authorized use and an upper limit M on the number of uses.

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

Further, in some embodiments, the issuing of the N digital assets corresponding to the intellectual property may specifically be: and if N is not greater than M, issuing N digital assets corresponding to the intellectual property rights, and re-using M-N as M. In this way, it is ensured that the number of digital assets issued from past times does not exceed the upper limit of the number of uses in orders contracted by the authorized party and the authorizing party.

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

By the method shown in fig. 6, an intellectual property right usage authorization system is established based on a blockchain network, one-time usage rights for intellectual property right under the chain are anchored to one digital asset on the chain, and an authorized party needs to acquire opportunities for legal one-time usage of the intellectual property right in a way of consuming one digital asset associated with the authorized party on the chain. In particular implementations, an authorized party submits application information through an intelligent contract in a blockchain network, the application information mainly specifying the intellectual property rights that the authorized party wants to use and the number of times N that the authorized party applies for use of the intellectual property rights. The authorizing party monitors the application information from the chain, invokes an intelligent contract in the blockchain network to issue N digital assets corresponding to the intellectual property rights, and creates an association relationship between the authorized party and the N digital assets.

In this way, the agreement between the authorized and authorized parties on the number of uses of the intellectual property (i.e., the terms of restrictions) will be documented and the one-time use right for the intellectual property will be anchored to one digital asset on the chain, and each legal use of the intellectual property by the authorized party will be required at the expense of one digital asset on the chain, so that each legal use of the intellectual property by the authorized party can be documented on the chain. In the event that the authorized party and the authorized party dispute the implementation of the terms of restriction on the number of intellectual property uses, the dispute may be resolved using a trusted record on the chain.

Correspondingly, the method shown in fig. 7 further comprises: at least one authorizer client, after monitoring an event message containing the order information, invokes an intelligent contract in a blockchain network to perform an order validation step: creating an order corresponding to the order information.

In some embodiments, creating an order corresponding to the order information may include: and under the condition that the number of the authorized party clients for calling the intelligent contracts in the blockchain network to execute the order confirmation step is not less than the specified number, creating an order corresponding to the order information.

In some embodiments, issuing the at least one digital asset corresponding to the intellectual property 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 ending time of the specified period.

By the method shown in fig. 7, an intellectual property right usage authorization system is established based on a blockchain network, one-time usage rights for intellectual property right under the chain are anchored to one digital asset on the chain, and an authorized party needs to acquire opportunities for legal one-time usage of the intellectual property right in a way of consuming one digital asset associated with the authorized party on the chain. In particular implementations, an authorized party submits application information through an intelligent contract in a blockchain network that primarily specifies the intellectual property rights that the authorized party wants to use and the period of time that the authorized party applies for use of the intellectual property rights. The authorizing party monitors the application information from the chain, invokes an intelligent contract in the blockchain network to issue at least one digital asset corresponding to the intellectual property, each digital asset has a validity period during use, and creates an association relationship between the authorized party and the at least one digital asset.

As such, the agreement (i.e., the terms of restriction) between the authorized and authorized parties during the use of the intellectual property may be documented and the one-time use right for the intellectual property anchored to one digital asset on the chain, each legal use of the intellectual property by the authorized party, may be required at the expense of consuming one valid digital asset on the chain so that each legal use of the intellectual property by the authorized party may be documented on the chain. In the event that the authorized party and the authorized party dispute the implementation of the terms of restriction during use of the intellectual property, the dispute may be resolved using a trusted record on the chain.

Fig. 8 is a flow chart of a method for authorizing the manufacture of an intellectual property product provided in the present specification, comprising:

s800: the authorized party client invokes the intelligent contract in the blockchain network to perform the asset application step.

The asset application steps in the method of fig. 8 include: and determining application information designated by the authorized party, and triggering event messages containing the application information. The application information specifies the intellectual property rights that are authorized for use.

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

The first transmitting step comprises the following steps: and issuing N title digital assets corresponding to the intellectual property rights. The first association step includes: and creating an association relationship between the authorized party and the N title digital assets.

S804: the authorized party client invokes an intelligent contract in the blockchain network to perform the second issuing step and the second associating step.

The second issuing step is as follows: n product digital assets are issued in one-to-one correspondence with the N base products. The second association step is as follows: a one-to-one association between the N title digital assets and the N product digital assets is created.

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

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

By the method of fig. 8, the authorized party makes an intellectual property product based on the base product to which the product digital asset associated with the property digital asset corresponds in a manner that consumes the one of the property digital assets associated with the chain.

In the method of fig. 8, the authorized party needs to be limited in two points when using the intellectual property to manufacture a product: 1. manufacturing an intellectual property product, requiring the consumption of its associated digital property asset; 2. in manufacturing this intellectual property product, it is necessary to use the base product corresponding to the digital asset of the product associated with the digital asset consumed for manufacturing. 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 the property digital assets on the chain, and the authorized party controls the product manufacturing behaviors of the authorized party based on the association relationship on the chain, so that the product manufacturing behaviors of the authorized party meet the agreement, and the authorized party is difficult to abuse the intellectual property product.

Continuing with the method of FIG. 8, the base product may be a physical base product (e.g., a coffee cup) or a virtual base product (e.g., a membership card of a cafe, the code in the card being a virtual product).

Further, in some embodiments, a third publishing step may be invoked to execute a smart contract in the blockchain network: 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, the authorized party can print or post the identification 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 identification of the combined digital asset into the code of the base product to obtain the intellectual property product.

Further, the third issuing step may be invoked by the authorizer client or the at least one authorizer client invoking an intelligent contract in the blockchain network.

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

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

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

respectively 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; if each verification passes, determining that the combined digital asset verification passes; if either verification fails, it is determined that the combined digital asset verification fails.

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

Fig. 9 is a schematic diagram of a blockchain-based IP brand usage authorization system provided herein. As shown in fig. 9, an IP authorization transaction intelligent contract is deployed in a blockchain network, and a plurality of IP merchants (IP merchant A, IP merchant C) and a plurality of IP copyrighters (IP copyrighter B, IP copyrighter D) can conduct IP authorization transactions through the blockchain network. It should be noted that, the IP brand of the on-link intelligent contract that the copyrighter publishes can be represented by using the subject of the copyrighted work owned by the copyrighter.

Fig. 10 is a schematic flow chart of a 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., usage up to 1000 times). Copyright party B (in effect corresponding to a plurality of specific copyright parties) needs to make a multiparty signature validation of the contract (i.e. the order information), create the order on the chain, and IP merchant a can simultaneously complete payment of the usage fee (the usage fee is locked into the order). The IP merchant a may then further specify a certain material under the IP brand (e.g. a certain animated character) as a specific usage modality using the IP brand, and the copyrighter B continues the signature verification. Then, the IP merchant a may apply for the copyright B to issue 1000 NFTs on the chain, each NFT corresponding to a single use opportunity, the copyright B may sign a confirmation, generate and issue 1000 NFTs on the chain.

Fig. 11 is a schematic flow chart of the charging of the on-chain account by the IP merchant based on the off-chain account provided in the present specification. As shown in fig. 11, the bank/financial institution is the under-chain account manager, the IP authorization chain (i.e., blockchain network described herein) funds gateway is the manager of the blockchain network interfacing responsible for interfacing with the under-chain account manager.

Fig. 12 is a schematic flow chart of an IP merchant purchasing IP brand usage rights on a chain provided in the present specification. As shown in fig. 12, IP merchant a places an order by an on-chain smart contract, resulting in an on-chain account deduction for IP merchant a, IP copyright party B acknowledges authorization, triggers the on-chain smart contract to create an order, and locks the usage charge in the order. The IP copyright party B can call the contract to execute the order presenting step by taking the order as granularity, and present the funds locked in the order to the own account under the chain in the bank. Each withdrawal of the IP rights party B is according to the fact that the account on the chain of the IP rights party B has no balance, the order is locked with funds, and after the order is withdrawn, the account model and the uxo model are considered to be spent.

Fig. 13 is a schematic flow chart of the IP copyright party extracting from the chain provided in the present specification. As shown in fig. 13, the IP rights party B invoking a contract to execute an order proposal step will cause the order status to change to proposed, and the contract triggers an event message, which is equivalent to mapping the amount locked in the order out of the chain. The funds of the under-chain account in the bank of the IP copyright party B are increased, and the funds in the under-chain account of the IP merchant A are thawed and deducted.

Fig. 14 and 15 are schematic diagrams of NFT flow-through provided in the present specification. The NFT codes authorized by each brand can be converted into two-dimensional codes to be printed on objects (such as water cups and clothes), and the objects can be communicated for the second time.

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