Examples
Referring to FIG. 1, FIG. 1 is a block diagram of a blockchain-based digital asset validation protection method in an embodiment of the invention. The digital asset right-determining protection method based on block chain provided by the invention specifically comprises the following steps S1 to S
Step S1, rights allocation information pre-agreed by at least two rights people is stored on the blockchain.
In this embodiment, whenever a two-party (or multi-party) right man generates a contract (i.e., rights allocation information, such as a collaborative contract), the contract may be uploaded and documented by the blockchain. Next, when the rights man generates a corresponding digital asset according to the contract and uploads it, it proceeds to step S2 to automatically authenticate the digital asset by the on-chain contract.
Step S2, when the digital asset uploaded by the rights man is received, the digital asset is subjected to rights allocation based on the rights allocation information to form asset rights allocation data.
Wherein the asset rights assignment data includes an ID of each rights person, an asset assignment proportion, and a rights range for recording rights of each rights person having the digital asset. The blockchain has disposed thereon a rights allocation contract for automatically performing step S2 described above upon receipt of a digital asset uploaded by a rights man, ensuring automation and compliance of the process.
In addition, in this embodiment, before receiving the digital asset sent by the rights issuer, the rights issuer is authenticated.
And step S3, generating a multiparty signature certificate according to the asset rights allocation data and the corresponding time stamp to store the multiparty signature certificate on the blockchain.
In this embodiment, the multiparty signature certificate is authenticated and non-tamperable on the blockchain for proving the authorized distribution of the digital asset.
And step S4, when a preset processing action executed on the digital asset is received, reminding a right person corresponding to the right scope based on the right related to the preset processing action so as to acquire the authorization of the right person.
In step S4 of the present embodiment, taking the transfer of a digital asset as an example, if the a, b, and c parties agree in advance that the digital asset is shared by the parties and cannot be transferred privately, then this information is processed in step S2 and is embodied in the rights scope in the asset rights allocation data. Next, if the first initiates a transfer action, the on-chain contract automatically sends a prompt to the second party based on the scope of the rights and allows the first party to continue to perform its transfer action only after both parties are authorized.
And S5, after the authorization of the right person is received, executing preset processing behaviors, and further distributing the fund flow according to the asset right distribution data and generating a corresponding asset confirmation right account book when the fund flow is generated by the preset processing behaviors.
In this embodiment, preset intelligent contracts corresponding to different preset processing behaviors are also deployed on the blockchain. The type of the preset processing behavior is a licensing behavior, a transferring behavior, a transaction behavior, a gifting behavior or a mortgage behavior, and at least one preset intelligent contract, such as a licensing contract, a transferring contract and the like, is arranged corresponding to each behavior.
In step S5 of the present embodiment, before executing the preset processing behavior, a corresponding preset smart contract is determined based on the type of the preset processing behavior, so that execution of the preset processing behavior is completed through the preset smart contract.
Taking the licensing of digital assets as an example, if the a, b and c parties agree in advance that the digital asset needs to be allocated a part of the licensing fees to the remaining two parties when the digital asset is licensed to other people for use and the licensing fees are charged, then the information is processed in step S2 and is embodied in the asset allocation proportion in the asset rights allocation data.
If the a initiates the action of licensing the digital asset, the type of action is first matched and the license contract is determined to be needed in step S5, and if the license is completed and the d has generated the benefit by using the digital asset, the license contract continuously records the benefit generated by the d and the corresponding generated license fee, and distributes the license fee to the a, b and c parties according to the asset distribution proportion. This approach ensures the fairness, transparency (transparency to the three parties of a, b and c) and high efficiency of the whole licensing process.
In addition, as another embodiment, if the preset processing behavior generates a change (such as transfer) of the rights, the corresponding preset smart contract determined in step S5 also generates a corresponding asset flow transfer book according to the change of the rights and the scope of the rights. The asset stream transfer book is used to record all rights currently and historic rights for the digital asset, and the corresponding rights range.
And S6, encrypting the asset confirmation rights account book and the asset stream transfer book based on the common key of the rights person and verifying the asset confirmation rights account book and the asset stream transfer book to the blockchain.
In this embodiment, the blockchain is deployed with an intelligent contract for querying, so that the rights and the supervisory party query the asset confirmation ledger and the asset stream transfer book through the shared key. Because the two account books are encrypted through the shared key of the right person, other people except the right person and the supervision party are prevented from checking the account books, and the data privacy of the right person is protected.
In one embodiment, the asset validation ledger may be non-tamperable.
However, as another implementation, if the automatic generation process of the asset validation ledger is unreliable, the modification of the rights man can be allowed.
At this time, when a request for modification of the asset validation ledger by the rights man is accepted, determining the relevant rights man based on the asset rights allocation data; after the authorization of the related rights man is obtained, a modification request is accepted, and the modified asset validation right account book and each history version are bound and stored.
In the process, the modified asset validation ledger is bound and stored with the previous history version, so that the whole modification process of the asset validation ledger can be disclosed, and the phenomenon of random tampering is avoided.
Finally, it should be noted that: the above examples are only specific embodiments of the present invention for illustrating the technical solution of the present invention, but not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the foregoing examples, it will be understood by those skilled in the art that the present invention is not limited thereto: any person skilled in the art may modify or easily conceive of the technical solution described in the foregoing embodiments, or perform equivalent substitution of some of the technical features, while remaining within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention, and are intended to be included in the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
