Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, terms such as "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying a relative importance or order.
As mentioned above, with the development of science and technology, more and more digital assets are available, and therefore, it is generally necessary to process these digital assets in order to determine their rightful persons. Especially when faced with a huge amount of digital assets, it will be of vital importance to process these digital assets in order to subsequently determine their righters.
As shown in fig. 1, the digital asset processing system 1 according to the embodiment of the present application includes a blockchain platform 10 and a plurality of clients 20, wherein the blockchain platform 10 is connected to each client 20, so as to enable data communication with each client 20. For example, the client 20 can upload digital assets to the blockchain platform 10 for storage, etc.
The digital asset may be a digital asset of graphic art, text, etc., an NTF (Non-fungal Token), or an audio-video digital asset of sound, animation, video, etc., for example, the digital asset may be a copyright of electronic music, etc.
In practical applications, the client 20 may be a client of an entitlement APP (application), and the client of the entitlement APP (application) may construct a service scene based on a specific service to guarantee digital asset interests, such as digital asset entitlement for graphic arts.
In addition, as shown in fig. 2, the blockchain platform 10 may specifically include an intelligent contract module 11, a server 12, and a blockchain 13, where the intelligent contract module 11 is configured to provide an intelligent contract or an intelligent contract template to the client 20, the server 12 is used as an operation platform for logically determining, calculating a hash value, and the blockchain 13 is configured to store data.
Based on the digital asset processing system 1 described above, the present application provides a digital asset processing method that can be performed by the blockchain platform 10 in the digital asset processing system 1, and in particular can be performed by the server 12 in the blockchain platform 10. As shown in fig. 3, the method comprises the steps of:
step S31: digital assets and owner information for the digital assets are obtained.
In practical application, a user can upload digital assets and owner information of the digital assets through a client, so that a server of a block chain platform can acquire the owner information of the digital assets. The owner information refers to personal information of a user who owns the digital asset ownership, for example, the owner information may be a unique identifier of the user, where the unique identifier may be a user name, an identification number, a contact address, or the like, or a login account of the user on the blockchain platform, or an identification code assigned by the blockchain platform 10.
For example, before a user sends the digital asset and the owner information of the digital asset to the blockchain platform through the client, the user may register with the blockchain platform by using personal information, and after the registration is successful, a registration account, a login password, and the like can be obtained, and in addition, the blockchain platform may allocate an identification code to the user, where the identification code can be used to associate a storage space in the blockchain that is specific to the user, such as generating the identification code by using a network address of the storage space; therefore, in the process of processing the digital assets, a user can log in the client by using the registered account number and the login password, and after the login is successful, the digital assets and the identification code (the identification code serves as the owner information of the sent digital assets) are sent to the blockchain platform.
It should be further noted that, before the user sends the digital asset and the owner information of the digital asset to the blockchain platform through the client, a target intelligent contract corresponding to the asset type of the digital asset may be determined through the intelligent contract module in the blockchain platform, for example, the intelligent contract module may obtain an intelligent contract corresponding to the asset type from a resource library of the intelligent contract module according to the asset type to serve as the target intelligent contract, or the intelligent contract module may obtain an intelligent contract template corresponding to the asset type from a resource library of the intelligent contract module according to the asset type, and further, the user edits, modifies, and the like the intelligent contract template to obtain the target intelligent contract.
For example, the user can select the asset type of the digital asset on the operation interface of the client, and then the intelligent contract module obtains the corresponding intelligent contract or intelligent contract template from the resource library of the intelligent contract module according to the asset type.
The resource library of the intelligent contract module can be used for storing intelligent contracts or intelligent contract templates corresponding to various asset types, the asset types of the digital assets can be divided according to actual needs, for example, the asset types can include NTF digital assets, graphic art and character digital assets, audio and video digital assets and the like.
In addition, based on different service scenes, different intelligent contract templates or intelligent contracts can be obtained from a resource library of the intelligent contract module, and even a user can define the intelligent contracts through the intelligent contract module according to different service scenes of the user and use the intelligent contracts as target intelligent contracts.
For example, for digital assets of the knowledge graph, a user can customize an intelligent contract (as a target intelligent contract) through an intelligent contract module according to actual needs, and the target intelligent contract comprises: providing the right uplink to which the data corresponding to the individual and the organization belong, finishing the individual distribution proportion control of the knowledge graph creator, and when the income exists, specifying how to measure and calculate the income proportion.
For the digital assets of the electronic ticket, the intelligent contract (as the target intelligent contract) can be customized by the intelligent contract module, and the target intelligent contract comprises: and linking the digital assets of the electronic ticket, carrying out purchase and delivery of the electronic ticket through the field time and combining with real-name authentication to finish credible electronic ticket selling so as to prevent the scalper party and the like.
For digital assets of the working experience/academic data, intelligent contracts (as target intelligent contracts) can also be customized by an intelligent contract module, and the target intelligent contracts comprise: the method has the advantages that the method can carry out the right-confirming service on the working experience and the academic data of the staff and construct credible and valuable professional guidance, thereby creating economic opportunities for each developer.
Digital assets (called digital art) created for the art of a photographer's photograph, artist or musician can also be customized (as a target intelligent contract) by an intelligent contract module, the target intelligent contract comprising: and completing data authority chaining, work storage and display on the completion chain and the like on the digital art work.
In addition, the user-defined intelligent contract can also comprise a block chain real-name authentication process, and based on the right of the real-name authentication system real-name authentication chain account address under the chain, the chain link of the authentication data is completed, and the trusted information inquiry and the like are submitted.
After the target intelligent contract is determined, the digital asset and ownership information is sent to the blockchain platform according to the requirements on the format, content, uploading mode and the like of the digital asset and ownership information in the target intelligent contract. Correspondingly, the server in the blockchain platform can acquire the digital asset and the owner information uploaded by the user at the client, at the moment, the digital asset and the owner information meet the requirements on format, content and uploading mode in the target intelligent contract, and the target intelligent contract is determined by the intelligent contract module according to the asset type of the digital asset.
Step S32: a hash value of the digital asset is determined.
After the digital asset is obtained in step S31, a hash function may be used to perform a hash operation on the digital asset, so as to determine a hash value of the digital asset. The hash function may be MD4, MD5, SHS or other hash functions, and the specific type of the hash function is not limited herein.
It should be noted that, it is mentioned above that the target intelligent contract corresponding to the asset type of the digital asset can be determined by the intelligent contract module in the blockchain platform, so that the user can send the digital asset and the owner information to the blockchain platform at the client according to the requirements of the target intelligent contract on the format, content, uploading manner, and the like of the digital asset and the owner information. In practical applications, in order to ensure information security, a privacy level may be further included in the target intelligent contract, for example, the privacy level may be high, medium, low, and the like, and different privacy levels correspond to different hash functions.
Therefore, in step S32, the specific way of determining the hash value of the digital asset may be to calculate the hash value of the digital asset according to a hash function corresponding to the security level in the target smart contract.
Step S33: and correspondingly storing the hash value and the ownership information into a confirmation data account book of the block chain.
After acquiring the owner information of the digital asset in step S31 and determining the hash value of the digital asset in step S32, the hash value and the owner information may be stored correspondingly, specifically, the hash value and the owner information are stored correspondingly in the weight data book of the block chain. In an embodiment, the blockchain provided by the embodiment of the present application may include a plurality of nodes, and a weight data book may be generated in some or all of the nodes, so that in step S33, the hash value and the owner information may be stored in one or more weight data books correspondingly, so that the hash value and the owner information and the corresponding relationship between the hash value and the owner information are stored by using the characteristics of the blockchain that cannot be forged and tampered.
In this confirmation data book, at least two fields, a hash value storage field and a ownership information storage field may be included, so that in this step S33, the hash value may be stored as a field value in the hash value storage field, and the ownership information may be stored as a field value in the corresponding ownership information storage field, thereby realizing the corresponding storage therebetween.
By adopting the digital asset processing method provided by the embodiment of the application, the digital asset and the owner information of the digital asset are obtained firstly, then the hash value of the digital asset is determined, then the hash value and the owner information are correspondingly stored in the weight data account book of the block chain, so that the digital asset is processed, and finally the hash value and the owner information of the digital asset are correspondingly stored in the weight data account book of the block chain through the processing, so that the characteristics of unforgeability and unforgeability of the block chain can be utilized, and the subsequent determination of the owner of the digital asset is facilitated.
In the above steps S31 to S33, the hash value of the digital asset and the owner information of the digital asset are stored in the determination data book of the block chain, so that the correspondence relationship between the two is stored in the block chain. In practice, the method may further include storing the digital asset in a distributed repository, thereby persisting the digital asset. The distributed repository may be a distributed repository established based on an InterPlanetary File System (IPFS), and the IPFS is a hypermedia transport protocol based on content addressing, versioning, and peer-to-peer, and is a P2P distributed File System. At the heart of IPFS is a distributed system for storing and accessing files, websites, applications, and data. Thus, the distributed repository built based on IPFS is transport layer independent and digital assets can be transferred through various transport layers, including TCP, UDT, QUIC, TOR, and even bluetooth, for storage into the distributed repository.
Thus, the distributed repository may be built in the cloud or locally using IPFS, and then digital assets can be stored in the distributed repository.
In an embodiment, the hash value and the owner information of the digital asset may be correspondingly stored in the ownership data book of the blockchain by using the above steps S31 to S33, so that when an ownership dispute of the digital asset occurs or the owner information of the digital asset needs to be confirmed due to other circumstances, the digital asset can be used as the digital asset to be queried, and then the client sends a request for querying the ownership data to the server of the blockchain platform, where the request for querying the ownership data includes the hash value of the digital asset to be queried. And the server can acquire the request for inquiring the right data, and then inquire the book of the right data by using the hash value of the digital asset to be inquired, so as to determine the owner information of the digital asset to be inquired.
Of course, after determining the ownership information of the digital asset to be queried, the ownership information of the digital asset to be queried may also be fed back to the client, or an ownership confirmation report is generated by using the ownership information of the digital asset to be queried, and then the ownership confirmation report is fed back to the client, so that the client can determine the ownership of the digital asset to be queried after receiving the ownership confirmation report or the ownership information of the digital asset to be queried.
It should be noted that, when a ownership dispute of a digital asset occurs or ownership information of the digital asset needs to be confirmed due to other situations, a user sends, at a client, a confirmation data query request to a server of a blockchain platform, where the confirmation data query request also includes the digital asset to be queried (instead of the hash value of the digital asset to be queried), so that after receiving the confirmation data query request, the server may recalculate the hash value according to the digital asset to be queried, and then query a confirmation data ledger using the hash value, so as to determine ownership information of the digital asset to be queried.
The foregoing is a detailed description of the digital asset processing method provided in the embodiments of the present application, and for convenience of understanding, the details of the related art of the method may be further described with reference to specific application scenarios. In this application scenario, the type of digital asset is specifically copyright.
