Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of blockchains, and particularly relates to a digital asset creation incentive method and device based on a blockchain, equipment and a medium. BACKGROUND

[0002] Digital collectibles as digital assets have become one of the hottest topics at present, and with the popularity of digital collectibles, the scale and market of digital collectibles are being continuously expanded. Digital collectibles rely on blockchain technology and play a key role in digital copyright.

[0003] Digital collectibles generate value transfer through buying and selling and circulation, and in this process, the original creators of digital collectibles usually cannot obtain benefits from the circulation of digital collectibles. After the value of digital collectibles is mined and expanded, the creators will not be able to obtain corresponding benefits, which will undermine the enthusiasm of creators. The protocols currently widely used for digital collectibles, such as ERC-721, ERC-1155 and ERC-998, are all focused on digital collectibles and their circulation, and lack an incentive method for creators.

[0058] In order to illustrate the technical solutions described in the present application, the following will be described by specific embodiments.

[0059] Reference Figure 1 , Figure 1 is a process of a digital asset creation incentive method based on a block chain provided by the embodiments of the present application Figure 1 . As Figure 1 shown, a digital asset creation incentive method based on a block chain, the method comprising the following steps:

[0060] Step 101, based on a preset asset minting contract, minting a first digital asset, creating a first asset account corresponding to the first digital asset and storing.

[0061] Among them, the first asset account includes a creator identification field and a creation source identification field.

[0062] Among them, the creator identification field is used to record the first creator identification of the first digital asset, and the creation source identification field is used to record the first account address of the second asset account corresponding to the second digital asset, the first account address is used to obtain the second creator identification of the second digital asset from the creator identification field of the second asset account, and the first digital asset is generated based on the second digital asset.

[0063] Here, the first creator identification and the second creator identification are specifically, for example, the account address of the creator, the ID number of the creator, etc.

[0064] Digital assets: Non-fungible tokens (NFT) are used to identify someone or something in a unique way. This type of token can be perfectly used for platforms that sell the following items: collectibles, keys, lotteries, concert seat numbers, sports matches, etc. Digital assets are formed as digital collectibles on the publishing platform.

[0065] The digital asset corresponds to an asset account, and the asset account is used to store the digital asset. Specifically, the created asset account is used to store the minted digital asset on the blockchain. In one example, in combination with Figure 2 As shown in the asset account structure is as follows:

[0066] The asset account includes an asset address field, a contract address field, an asset identification field, an asset state field, an owner address field, a creator address field, a creation source address field, and a custom information field.

[0067] The asset address field is used to record the asset address. The asset address is the storage address of the asset account. Since the digital asset can only be stored once in different blockchains or different contracts, the asset address can be used as unique identification information of the asset account corresponding to the digital asset.

[0068] The contract address field is used to record the contract address of the current asset account. The contract address is the contract address of the digital asset contract. Since a contract can contain multiple asset accounts of digital assets, the contract address in the asset parameter cannot uniquely identify the asset account.

[0069] The asset identification field is used to record the asset identification information of the digital asset. The asset identification is the identification information of the asset account. The asset identification in the same contract is different, but the asset identification in different contracts can be the same or different. Since the asset account can exist across contracts, the asset identification in the entire chain or different contracts cannot uniquely identify the asset account. However, the asset account can be used as unique identification information of the asset account corresponding to the digital asset, or the asset identification and the contract address can be used as unique identification information of the asset account corresponding to the digital asset.

[0070] The asset state field is used to record the current state of the digital asset. The asset state is the state information of the asset account corresponding to the digital asset. The asset state can be set according to user needs, for example, the asset state is set to active.

[0071] The owner address field is used to record the owner address information of the digital asset. The owner of the digital asset has the copyright and usage right of the current digital asset. The owner address is the address of the owner of the asset account corresponding to the digital asset. For example, the owner address records that the owner of the asset account is A.

[0072] The creator address field is used to record the creator address information of the current digital asset. The creator address is the address of the creator account of the current digital asset.

[0073] The creation source address field is used to record address information of another digital asset in the case that the current digital asset is generated by secondary processing and creation based on the other digital asset. The address information of the other digital asset is specifically the address of an asset account corresponding to the other digital asset, and based on the address of the asset account corresponding to the other digital asset, an owner address recorded in the asset account corresponding to the other digital asset is obtained (forming an owner identifier).

[0074] The custom information field is used to record custom information of the digital asset. The custom information is created according to the requirements of a user on the asset account corresponding to the digital asset.

[0075] Correspondingly, the creator address field in the above example is one of the creator identifier fields in the embodiments of the present application, and the creation source address field is one of the creation source identifier fields in the embodiments of the present application.

[0076] In the embodiments of the present application, in order to be able to realize the incentive to the creator of the digital asset, the creator identifier is added in the storage protocol content of the digital asset, and in order to be able to make the market of the digital asset more extensive, the protocol allowing the owner of the digital asset to create again is added, and a new digital asset will be generated after the secondary creation, but it will be recorded that which digital asset is the creation source of the current digital asset generated by the secondary creation, that is, the creation source identifier is added in the storage protocol content of the digital asset to indicate that the current digital asset is created again by which digital asset.

[0077] The creator identifier field and the creation source identifier field can be used to record information, and a part of the income of the digital asset can be used to incentivize the creator of the current digital collectible and the creator of the digital collectible of the work creation source.

[0078] In the specific implementation, in the case that the first digital asset is a first creation digital asset, the creator identifier field is the first creator identifier of the first digital asset, and the creation source identifier field is empty.

[0079] In the case that the first digital asset is a secondary creation digital asset, the creator identifier field is the first creator identifier of the first digital asset, and the creation source identifier field is the first account address of the second asset account corresponding to the second digital asset.

[0080] The first creation digital asset refers to a digital asset that is created for the first time.

[0081] The digital asset is a digital asset generated by secondary creation based on other digital assets.

[0082] The above embodiment increases new protocol content to meet the demand for digital asset creation incentives on the basis of the widely used ERC-721 protocol of the current digital asset. The two protocol interfaces of casting digital collectibles and transferring digital collectibles are mainly expanded to enable the effective operation of the protocol and the incentive system by expanding the underlying technology.

[0083] First, there are two cases for the casting digital asset interface. One is the casting of completely original digital assets, and the other is the casting based on the secondary creation of a digital asset.

[0084] In combination with Figure 3 If it is the casting of original digital assets, the protocol requires that the creator address be supplemented when casting a new digital asset, that is, the blockchain account address of the initiator of the current digital asset casting transaction, the owner address at this time is the same as the creator address, and the creation source address is empty, indicating that it is an original type digital asset.

[0085] In combination with Figure 4 If it is the casting of a digital asset based on the secondary creation of a digital asset, the protocol requires that the asset account address of the digital asset of the creation source be provided additionally when casting, and it is verified whether the owner account address of the digital asset of the creation source is consistent with the account address of the initiator of the current casting transaction. Only in the case of consistency can the secondary creation casting be carried out, otherwise it does not have the copyright.

[0086] When the address is checked, a digital asset account is created, and the creator address and the owner address are filled in as before when casting original digital assets, that is, the blockchain account address of the initiator of the current casting transaction, and the asset account address of the digital asset of the creation source is written in the creation source address field of the digital asset account.

[0087] Further, in the specific implementation process, the digital asset management equipment calls the contract execution engine in the underlying logic architecture of the digital asset account, and the contract engine creates a digital asset according to the asset parameters based on the preset asset casting contract, creates a digital asset corresponding to the asset account and stores it.

[0088] Correspondingly, in an optional embodiment, in combination with Figure 5 As shown in the figure, the first digital asset is cast based on the preset asset casting contract, the first asset account corresponding to the first digital asset is created and stored, which includes:

[0089] Step 501, calling a contract execution engine in a digital asset account underlying logic architecture, inputting asset parameters into the preset asset minting contract in the contract execution engine;

[0090] Step 502, calling a digital asset account creation interface of a preset chain ledger through the preset asset minting contract, inputting the asset parameters into the digital asset account creation interface, and creating the first asset account;

[0091] Step 503, creating an account type corresponding to the first digital asset in a preset ledger according to the asset type of the first digital asset, and storing the first digital asset transmitted by the first asset account.

[0092] The asset parameters include at least one of an asset address, a contract address to which the asset belongs, an asset identifier, an asset state, an owner address, a creator address, a creation source address, and custom information.

[0093] That is, the digital asset management device calls a contract execution engine in a digital asset account underlying logic architecture, the digital asset management device inputs asset parameters into a preset asset minting contract in the contract execution engine, the preset asset minting contract calls a digital asset account creation interface of a preset chain ledger, inputs the asset parameters into the digital asset account creation interface, and creates a first asset account; the digital asset management device creates an account type corresponding to the first digital asset in a preset ledger according to the asset type of the first digital asset, and stores the first digital asset transmitted by the asset account. Refer to Figure 2 , Figure 2 The asset parameters contained in the asset account corresponding to the digital asset are recorded in the digital asset.

[0094] In this embodiment, the digital asset and the asset account corresponding to the digital asset are created and saved according to the asset parameters, the digital asset is also mapped as a kind of underlying account of a block chain, so that the asset account is derived from the block chain, and because the digital asset is chain-level data, the interface can be directly provided by the block chain to operate the digital asset without a contract, becoming a block chain that naturally supports the function of the digital asset, improving the execution efficiency while flexibly customizing the logic with the smart contract.

[0095] And in this embodiment, the digital asset creator and the digital asset creation source information for creation incentive are originally added in the account model, so that the creation incentive agreement can be realized on the original block chain account model.

[0096] Further, in an optional embodiment, the preset asset minting contract corresponds to a protocol identifier; correspondingly, after the first digital asset is minted based on the preset asset minting contract and the first asset account corresponding to the first digital asset is created, the method further includes:

[0097] Based on the protocol identification, a detection processing flow corresponding to the preset asset minting contract is selected;

[0098] Based on the detection processing flow, a field information validity detection of the first asset account is performed.

[0099] Specifically, the identification of the preset asset minting contract is implemented inside the smart contract execution engine, and the information post-detection of the asset account generated by the minting is performed to ensure that the protocol content can be triggered and to prevent the occurrence of vulnerability contracts. In the implementation, the interface implemented by the contract needs to be specified when the preset asset minting contract is written. The interface here refers to the protocol of the contract, and the contract explicitly provides the ability to the outside by implementing the interface protocol.

[0100] After the smart contract is loaded by the execution engine, that is, the contract is deployed to the blockchain, in combination with Figure 6 As shown in the figure, the contract execution engine records the protocol identification of the interface protocol implemented by the contract that can be identified by the protocol identification module in the contract protocol field in the contract account. The protocol identification is specifically the protocol name, the protocol number, etc.

[0101] Specifically, when the contract is deployed to the blockchain to form a contract account, the contract is mainly executed in the form of bytecode by the execution engine, and the protocol identification module of the execution engine can obtain the interface protocol implemented by the contract through the contract information recorded in the bytecode.

[0102] And the validity detection of the field information of the asset account can be implemented through the post-detection function of the smart contract execution engine, without explicitly writing the detection code in the contract. The precondition is that the HPC921 protocol identification is added when the contract is written. The smart contract post-detection module will judge whether the contract is the minting method of the HPC921 protocol after the execution of the preset asset minting contract method in the contract account is completed. If so, the corresponding legality detection method is run, and the detection content is the detection content described in the above protocol to ensure the data security of the digital collectible.

[0103] Step 102, in the case of the first digital asset transaction transfer, based on the creator identification field and the creation source identification field in the first asset account, a preset payment cooperation contract is called to perform income distribution processing.

[0104] The preset payment cooperation contract is the contract content corresponding to the minting based on the digital asset creation incentive method in the embodiments of the present application.

[0105] The first digital asset transaction transfer process generates a benefit. In an example, the benefit content can specifically include two parts of digital collectible value and transaction fee.

[0106] When the benefit is distributed, the digital collectible value part of the benefit is distributed to the owner of the digital asset, and the transaction fee part of the benefit is distributed among the creators as an incentive.

[0107] In an optional implementation, the step of calling a preset payment distribution agreement to perform benefit distribution processing based on the creator identification field and the creation source identification field in the first asset account includes:

[0108] In the case where the first digital asset is a first creation digital asset, information is extracted from the creator identification field and the creation source identification field to obtain the first creator identification of the first digital asset.

[0109] The preset payment distribution agreement is called to distribute the transaction gain part of the benefit to a first creator account corresponding to the first creator identification.

[0110] The transaction gain part can specifically be the transaction fee part of the benefit generated in the first digital asset transaction transfer process.

[0111] In another optional implementation, the step of calling a preset payment distribution agreement to perform benefit distribution processing based on the creator identification field and the creation source identification field in the first asset account includes:

[0112] In the case where the first digital asset is a second creation digital asset, information is extracted from the creator identification field and the creation source identification field to obtain the first creator identification of the first digital asset and a first account address of the second asset account corresponding to the second digital asset.

[0113] Based on the first account address, the second creator identification of the second digital asset is obtained from the creator identification field of the second asset account.

[0114] The preset payment distribution agreement is called to distribute the transaction gain part of the benefit to a first creator account corresponding to the first creator identification and a second creator account corresponding to the second creator identification according to a set proportion.

[0115] In yet another optional implementation, the first account address is further used to obtain a second account address of a third asset account corresponding to a third digital asset from a creation source identifier field of the second asset account, and the second account address is used to obtain a third creator identifier of the third digital asset from a creator identifier field of the third asset account.

[0116] Correspondingly, the preset payment distribution contract is called to perform the income distribution processing based on the creator identifier field and the creation source identifier field in the first asset account, including:

[0117] In the case that the first digital asset is a secondary creation digital asset, information is extracted from the creator identifier field and the creation source identifier field respectively to obtain the first creator identifier of the first digital asset and a first account address of the second asset account corresponding to the second digital asset.

[0118] Based on the first account address, a second creator identifier of the second digital asset is obtained from a creator identifier field of the second asset account, and a second account address of a third asset account corresponding to a third digital asset is obtained from a creation source identifier field of the second asset account.

[0119] Based on the second account address, a third creator identifier of the third digital asset is obtained from a creator identifier field of the third asset account.

[0120] The preset payment distribution contract is called to distribute a transaction gain part of the income to a first creator account corresponding to the first creator identifier, a second creator account corresponding to the second creator identifier, and a third creator account corresponding to the third creator identifier according to a set proportion.

[0121] In the case that the first digital asset is a secondary creation digital asset, information is extracted from the creator identifier field and the creation source identifier field respectively to obtain the first creator identifier of the first digital asset and a first account address of the second asset account corresponding to the second digital asset.

[0122] In the above implementation, the protocol interface for transferring digital collectibles is extended based on the ERC-721 protocol.

[0123] When digital collectibles are transferred, value is transferred. Generally, in addition to transferring the value of the digital collectible itself to the original owner at the time of purchase, the buyer also needs to pay a transaction fee. This transaction fee is used for transaction service fees and digital collectible creation incentives. The current agreement requires that when digital collectibles are transferred, a portion of the transaction fee be transferred to the creator of the digital collectible, and the specific percentage can be determined by the contract writer, i.e., the project team that initiated the digital collectible. There are also two scenarios here:

[0124] Combination Figure 7 As shown, one type is the transfer of original digital collectibles, which do not have source identification information. Therefore, when incentivizing creation, only the incentives for the creators of the current digital collectibles need to be considered.

[0125] Combination Figure 8 As shown, another type is the digital collectible that has been recreated. In this case, the source of creation information records the asset account address information of the second digital asset. When the second asset account corresponding to the second digital asset is accessed, the creator's identifier of the second digital asset can be extracted from the second asset account.

[0126] In this process, based on the asset account address in the source of creation identifier field, the asset account corresponding to the digital asset of the source of creation is obtained recursively. Similarly, the asset account also contains the creator identifier field and the source of creation identifier field. The creator address of the digital asset of the source of creation (the owner address is consistent with the creator address) can be obtained from the creator identifier field in the asset account to obtain the creator information of the digital asset and the digital asset of the source of creation. Ultimately, the incentive distribution of asset transaction revenue between the creator of the digital asset and the creator of the digital asset of the source of creation is realized.

[0127] Furthermore, the source identifier records the asset account address information of the second digital asset. This asset account address information can be used to extract the creator identifier of the second digital asset from the second asset account when accessing the second asset account corresponding to the second digital asset, and to obtain the asset account address corresponding to the digital asset from which the creation of the second digital asset originated from the source identifier field of the second asset account.

[0128] In this process, based on the asset account address in the creation source identifier field of the second asset account, the asset account corresponding to the digital asset (i.e., the third digital asset) that is the creation source of the second digital asset is further obtained recursively, and the creator identifier of the third digital asset is extracted from the third asset account.

[0129] Specifically, the third asset account also includes a creator identification field and a creation source identification field. The second account address is also used to obtain a third account address of a fourth asset account corresponding to a fourth digital asset from the creation source identification field of the third asset account, and the third account address is used to obtain a fourth creator identification of the fourth digital asset from the creator identification field of the fourth asset account; the third digital asset is generated based on secondary creation of the fourth digital asset.

[0130] In this case, when the preset payment distribution agreement is called to perform the income distribution processing based on the creator identification field and the creation source identification field in the first asset account, it includes:

[0131] In the case where the first digital asset is a two-creation digital asset, information is extracted from the creator identification field and the creation source identification field, respectively, to obtain the first creator identification of the first digital asset and the first account address of the second asset account corresponding to the second digital asset;

[0132] Based on the first account address, the second creator identification of the second digital asset is obtained from the creator identification field of the second asset account, and the second account address of the third asset account corresponding to the third digital asset is obtained from the creation source identification field of the second asset account;

[0133] Based on the second account address, the third creator identification of the third digital asset is obtained from the creator identification field of the third asset account; and it is judged whether the creation source identification field value of the third asset account is empty. If not, the third account address of the fourth asset account corresponding to the fourth digital asset is obtained from the creation source identification field of the third asset account, and the fourth creator identification of the fourth digital asset is obtained from the creator identification field of the fourth asset account based on the third account address. If it is empty, the preset payment distribution agreement is called to distribute the transaction gain part of the income to the first creator account corresponding to the first creator identification, the second creator account corresponding to the second creator identification, the third creator account corresponding to the third creator identification, and the fourth creator account corresponding to the fourth creator identification according to the set proportion.

[0134] In the above process, through recursive processing, when it is determined that the value of the creation source identification field of a certain asset account is empty, the preset payment distribution agreement is finally called to distribute the transaction gain part of the income to the creator account corresponding to each digital asset according to the set proportion.

[0135] The process determines multiple creator addresses that need to be incentivized through recursion, and at this time, the incentive part of the creation income (the transaction gain part of the income) is allocated to all creators.

[0136] Further, in the above process, in the digital collectible transaction transfer part, the smart contract execution engine will also work, specifically, after the end of the contract method execution, it will be judged based on the protocol identifier corresponding to the asset account after the transfer of the first digital asset whether the contract adopted is the transfer method under the HPC921 protocol, if so, the incentive content division will be run, the division ratio will be automatically obtained according to the specified ratio in the contract protocol, the creator information of the digital collectible will be automatically obtained, and the incentive distribution will be automatically performed, the division logic is as described in the foregoing rules, to prevent the case of smart contract abuse harming the rights and interests of creators.

[0137] The above-mentioned digital asset creation incentive method based on a blockchain of the present application will be described in detail below with reference to a specific example.

[0138] User 1 creates a digital collectible and casts it through the protocol of the current scheme, generating a digital collectible, and the blockchain underlying layer generates an asset account P1 for recording the digital collectible, and records the creator and owner of the digital collectible as the account address of user 1 when generating P1 according to the requirements of the protocol, and the creation source address is empty.

[0139] User 2 purchases the digital collectible corresponding to the asset account P1, at this time the owner address on the asset account P1 will be changed to the account address of user 2. At the same time, after user 2 purchases the digital collectible, it will pay the value corresponding to the digital collectible to user 1, as well as the transaction fee of this transaction, part of the transaction fee will be used as the creation incentive for the creator of P1, i.e. user 1, and the specific proportion of the incentive is determined by the specific smart contract.

[0140] User 2 obtains the copyright and ownership of P1 after purchasing it, and then creates a new digital collectible by re-creating it, and creates a new asset account P2 for recording the digital collectible when casting the new digital collectible, and records the creator and owner as user 2 on P2, and the creation source as the asset account address of P1.

[0141] User 3 purchases the digital collectible corresponding to the asset account P2. At this time the owner address on the asset account P2 will be changed to the account address of user 3. At the same time, after user 3 purchases the digital collectible, it will pay the value corresponding to the digital collectible to user 2, as well as the transaction fee of this transaction. Part of the transaction fee will be used as the creation incentive for the creator of P2, as well as the creator of the creation source P1 of P2, and the specific division ratio of the incentive is determined by the specific smart contract.

[0142] Further, in an optional embodiment, the first asset account further comprises an asset owner identification field for recording the owner identification of the first digital asset.

[0143] Before the income distribution processing is performed by calling the preset payment distribution contract based on the creator identification field and the creation source identification field in the first asset account in the case of the first digital asset transaction transfer, the method further comprises:

[0144] In response to the asset transaction request, the initiator identification of the asset transaction request and the owner identification in the asset owner identification field are obtained.

[0145] In the case where the initiator identification is determined to be the same as the owner identification, the transaction transfer of the first digital asset is performed.

[0146] In the above process, it is verified whether the owner account address of the digital collectible of the creation source is consistent with the account address of the current casting transaction initiator. Only in the case of consistency, the asset transaction transfer can be performed, otherwise it does not have the copyright, ensuring the legality of the transaction.

[0147] The above process proposes a new digital collectible protocol based on the underlying technology of the blockchain. Based on the relatively mature protocol content, the protocol is expanded to allow the owner of the digital collectible to create again and the original creator of the digital collectible will continue to receive incentives in the subsequent transaction process. The protocol encourages the creation of digital collectibles. And this series of content through the expansion of blockchain technology, automatically identify the contract protocol content and do the necessary detection, guarantee the safety of data.

[0148] In the first digital asset transaction transfer process, it can be:

[0149] According to the target asset parameter associated with the asset transfer request, the first digital asset in the asset account is transferred, including:

[0150] The target asset parameter associated with the asset transfer request is obtained.

[0151] If the target asset parameter is the contract address, the initial contract address of the asset account is updated to the contract logic in the preset contract execution engine. The contract address is updated to the contract address, and the digital asset transfer is completed.

[0152] If the target asset parameter is user identification information, the owner information contained in the owner identification corresponding to the asset account is adjusted to the asset recipient information corresponding to the user identification information, and the digital asset transfer is completed.

[0153] Wherein, the first digital asset in the asset account is transferred according to the target asset parameter associated with the asset transfer request, including:

[0154] The target asset parameter associated with the asset transfer request is obtained, and the asset state in the target asset parameter is extracted; if the asset state is an editable state, the first digital asset in the asset account is transferred.

[0155] In the embodiment of the application, the first digital asset is cast based on a preset asset casting contract, a first asset account corresponding to the first digital asset is created and stored, and the created first asset account includes an author identifier field for recording the author identifier of the first digital asset and a creation source identifier field for recording the first account address of the second asset account corresponding to the second digital asset, so as to obtain the second author identifier of the second digital asset from the author identifier field of the second asset account through the first account address. The creation source identifier field can be used to indicate which digital asset is used to create the current digital asset again. In the case of first digital asset transaction transfer, based on the author identifier field and the creation source identifier field in the asset account, a preset payment agreement is called to execute the income distribution processing, and a part of the income of the digital asset is used to encourage the author of the current digital collectible and the author of the digital collectible as the source of the work creation. Through digital asset casting and income distribution, effective creation incentive is realized.
