Description
Technical Field
The application belongs to the technical field of block chains, and particularly relates to a digital asset chaining method and device.
Background
In the prior art, digital assets (NFT products) issued by each large company often cannot be directly interacted among different series, and thus a data island problem is formed.
The ERC-721 protocol is a standard interface for Non-homogeneous tokens (NFT for short). Taking a parking space as an example, two parking spaces are equivalent to Token of two ERC-721, and different parking spaces may have different values, but even if the parking spaces have the same value, the asset numbers of the two parking spaces are different, so that each parking space is unique and not interchangeable under the ERC-721 protocol. Therefore, based on the ERC-721 protocol, the parking space can be easily traced, the right of the parking space can be quickly confirmed, and the problem of pain of the ownership of the parking space property rights in the industry is solved.
While ERC721 greatly lowers the threshold for issuing NFT products, at the same time, there are many problems, such as the inability of one address to send multiple NFT products to another address at the same time, the inability to send NFT products to multiple objects at the same time, and the inability to cast multiple token types at the same time in one contract. Only one token type can be cast at a time, and the consequences of this are low efficiency, high commission, and in many scenarios large short plates are used.

Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of this application and the above-described drawings, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to the technical scheme, the data acquisition, storage, use, processing and the like meet relevant regulations of national laws and regulations.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The invention aims to solve the problem of complex data cooperation under the condition that data on a current block chain cannot protect privacy.
Based on the technical pain point, an embodiment of the present invention provides a specific implementation of a digital asset uplink method, and referring to fig. 1, the method specifically includes the following steps:
step 100: assigning unique identifiers to different types of digital assets and to different data assets of the same type;
the NFT digital products of the original ERC721 are limited by one contract that intelligently releases one digital product, and different digital products are different contracts in nature, resulting in a certain degree of digital islanding, which is not beneficial to the interaction of different series of products. When a new NFT digital product based on the original ERC721 is released, a new contract is often deployed, so that the NFT digital product is not fast and convenient to popularize, and therefore, different types (series) of digital assets need to be uniformly distributed to Tokenid to overcome the problem.
Step 200: performing a chaining operation on the different types of digital assets according to the unique identifier, wherein: the unique identifications of the different types of digital assets are sequential.
Specifically, the newly-built NFT digital product is realized by calling a contract corresponding interface on a block chain infrastructure through a block chain gateway.
From the above description, it can be seen that an embodiment of the present invention provides a digital asset uplink method, including: firstly, giving unique identification to different types of digital assets and different data assets of the same type; and then, performing uplink operation on the digital assets of different types according to the unique identifier, wherein: the unique identification of the different types of digital assets is sequential. The invention can realize that all NFT digital products are based on the same contract through the optimized ERC721 protocol, thereby eliminating the island problem of different digital products and facilitating the exchange or interaction of different series. In addition, the invention can ensure that the intelligent contract is deployed only once, thereby greatly improving the push-out speed of the NFT digital product.
In one embodiment, referring to fig. 2, step 200 comprises:
step 201: determining the Tokenid of the digital assets according to the unique identifiers of the different types of digital assets and the unique identifiers of the same type of different data assets;
step 202: and performing uplink operation on the different types of digital assets according to the Tokenid.
In step 201 and step 202, further optimization is performed based on the ERC721 protocol. The optimization content is that the token in the protocol is generated, and the token is added from the original one and is added to the original one, and is assigned based on the other two newly created member variables NFTid and id.
The NFTid means unique identifiers of different NFT series, that is, global identifiers of NFTs of different series configured based on the contract. NFTid starts from 0 and increases by one for every new series.
id means the local identification of different NFT assets cast within the same series. Suppose the total number of NFT published assets in the ith series is N i The calculation and assignment formula of the unique global NFT asset identifier tokenid of the jth digital asset in the ith series in the contract is as follows:
In one embodiment, the Tokenid is a decentralized identity DID.
It is noted that when done on a public, decentralized blockchain, this gives the owner the custody and full ownership of their digital identity and their manner of use-just as having your private key can have your cryptocurrency in its entirety. This is subsequently referred to as Decentralized Identity (DID). The DID may also contain different personal information and identities that are kept in the same location, just as a wallet may hold different standards of cryptocurrency tokens.
Rather than having multiple digital identities managed by multiple centralized providers (e.g., driver's license managed by DMV, Google account managed by Google, bank account managed by bank, etc.), individuals may own a digital identity that contains all of this information and is managed separately. Since a third party need not be trusted to keep it, these identities must not be used for any purpose without the express consent of the owner.
In one embodiment, referring to fig. 3, the method for digital asset uplink further comprises:
step 300: building a block chain according to a unique identifier, wherein the unique identifier is given to a node and at least one digital asset publishing node, and the unique identifier is used for giving the unique identifier to the digital asset published by the digital asset publishing node; the digital asset publishing node is used for publishing the digital asset.
From the above description, it can be seen that an embodiment of the present invention provides a digital asset uplink method, including: firstly, giving unique identification to different types of digital assets and different data assets of the same type; and then, performing uplink operation on the digital assets of different types according to the unique identifier, wherein: the unique identification of different types of digital assets is sequential. The invention can realize that all NFT digital products are based on the same contract through the optimized ERC721 protocol, thereby eliminating the island problem of different digital products and facilitating the exchange or interaction of different series. In addition, the invention can ensure that the intelligent contract is deployed only once, thereby greatly improving the speed of launching the NFT digital product.
