Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a digital asset classification management method based on a block chain.
Background
A block chain (Blockchain) is a block chain data structure that organizes data records in blocks, arranges the blocks in time sequence, and combines the blocks end to end by the hash value of the previous block. A blockchain is essentially a Distributed Ledger Technique (DLT) that employs cryptographic algorithms to ensure that records in a block are not tampered and forged. The blockchain technology has the characteristics of decentralization, openness and transparency, difficulty in falsification, data traceability and the like, so that the blockchain technology has been researched and applied in numerous fields.
A Smart Contract (Smart Contract) refers to a program that can be automatically executed on a blockchain. Developers use intelligent contracts to build blockchain applications, mostly for building back-end business services. A Digital Asset (Digital Asset) is a Digital value object that is defined and managed by a blockchain smart contract and represents a specific Asset or service right. Digital assets include the digitization of virtual and physical assets, and blockchain techniques can be used to define, distribute, and manage these digital assets. Technically, a typical solution for implementing digital assets is to create and maintain digital asset contracts on blockchain platforms by means of Smart Contract (Smart Contract) technology, in which contracts the information, functions and other elements of the assets are defined, which are used by users through interaction with the contracts.
Typical applications for digital assets are electronic tickets, digital rights, proof of property, game tokens, digital identities, shares, votes, ownership, rights of use, collectibles, etc. It should be noted that the objects, as long as they can be represented digitally, can be characterized by digital assets (or digital tokens). These assets or tokens may represent different information and usage functions depending on the application. Technically, these digitized objects may be represented by a blockchain data structure, such as a digital asset (or digital token). Different digital assets exist in different blockchain platforms and different blockchain applications, and the digital assets are generated along with the development of the blockchain applications and can meet the requirements of specific applications or services, but the digital assets constructed by the current technical scheme have the problems of incomplete functions, poor mobility, poor compatibility, poor expansibility and the like, and the development of the blockchain digital asset field is limited.

Detailed Description
The following description of the embodiments of the present invention is provided in order to better understand the present invention for those skilled in the art with reference to the accompanying drawings. It is to be expressly noted that in the following description, a detailed description of known functions and designs will be omitted when it may obscure the subject matter of the present invention.
Examples
To better explain the technical solution of the present invention, a brief description will be given to the digital asset model on which the present invention is based.
Based on the purpose of improving the universality of the digital assets, the invention provides a digital asset model which is universal on various block chains and is independent of specific block chain technologies and applications. FIG. 1 is a schematic diagram of a digital asset model of the present invention. As shown in FIG. 1, the digital asset model of the present invention includes asset information, asset properties, and asset functions.
Asset information refers to identity data that distinguishes digital assets from other assets. The present invention defines the basic information that a digital asset should have (i.e., general information), including the asset name, asset symbol, asset issuance volume, and the smallest transaction unit of the asset. In addition, the digital assets may have additional information such as asset description, asset icon, asset link (for binding the mapping of the digital assets to the physical assets), and the like.
Asset properties refer to the interchangeability of digital assets, which refers to whether any two digital assets represent the same good, service, or benefit. From interchangeability, the present invention divides digital assets into three categories: an interchangeable Digital Asset (funnible Digital Asset), a Non-interchangeable Digital Asset (Non-funnible Digital Asset), and a partially interchangeable Digital Asset (Semi-funnible Digital Asset).
Asset functionality refers to the basic operations that a digital asset contract needs to provide when a user uses and manages a digital asset on a blockchain. The invention defines the basic functions that 8 digital asset contracts should have: create, issue, query, transfer, add, freeze, destroy, and authorize. The basic functions can provide complete digital asset management services and support the development and design of any digital asset related application.
Based on the digital asset model, the digital assets can be represented and then classified and managed, so that the digital assets can flexibly flow in different block chains.
Fig. 2 is a flow chart of an embodiment of the digital asset classification management method based on the blockchain according to the invention. As shown in fig. 2, the specific steps of the block chain-based digital asset classification management method of the present invention include:
s201: determining digital asset information:
according to the practical situation of the block chain application scene, determining the digital asset information comprising the name, the symbol, the issuing total amount and the minimum transaction unit of the digital asset.
S202: grouping of digital assets:
and grouping the digital assets in the block chain according to the actual situation of the block chain to obtain a plurality of digital asset groups.
S203: digital asset classification:
determining the category of each group of digital assets according to the interchangeability of the digital assets, and the specific method comprises the following steps:
if all digital assets within a group of digital assets do not differ in the goods, services or benefits that they represent, or there is no difference in the sense of exchange between any two instances of the assets (since both represent the same object, they do not have the sense and need of exchange), then it is determined that the group of digital assets belongs to an interchangeable type of digital asset. Generally, the digital asset group consisting of tokens, points, etc. in the blockchain belongs to an interchangeable type digital asset.
If any two digital assets in all the digital assets in the digital asset group are different in goods, services or rights and interests represented by the two digital assets, the group of digital assets are judged to belong to the non-interchangeable type digital assets, and a digital asset ID is allocated to each type of digital assets. For example, in a scenario where the digital rights of an article are represented by a digital asset, the digital rights of article a or the digital rights of article B cannot be directly exchanged with each other, and belong to an irreplaceable type of digital asset. There are other digital assets such as collectibles, cyber pets, digital identities, and the like.
If all digital assets in the digital asset grouping can be divided into a plurality of subsets, the digital assets in the subsets have interchangeability, and the digital assets between the subsets have no interchangeability, the group of digital assets is judged to belong to the partially interchangeable type digital assets, and a digital asset sub-class ID is allocated to each digital asset subset. Digital assets are partially interchangeable when they are used to construct objects in a blockchain having a hierarchical or sub-category structure, such as shares, securities, memberships, etc.
Fig. 3 is an exemplary diagram of digital asset classification. Representative assets for each type of digital asset in the existing blockchain application scenario are listed in fig. 3.
S204: digital asset management:
in the invention, a digital asset contract is created and managed for each digital asset in a block chain, the digital asset management comprises 8 functions including creation, distribution, inquiry, transfer, distribution augmentation, freezing, destruction and authorization, and each function is explained in detail below:
digital asset creation
When a digital asset needs to be created, a user firstly queries on the blockchain according to digital asset information to be created, if the digital asset information already exists, the digital asset is created in the blockchain, and the digital asset is not repeatedly created, and if the digital asset information does not exist, a digital asset contract is created on the blockchain according to the digital asset information and classification to provide digital asset service operation.
Digital asset distribution
The digital asset manager transfers the digital asset from a preset specific account to the account of the target user according to the agreed asset issuing rule. Technically, digital asset issuance is essentially a process of asset transfer, which differs in that asset issuance is transferred from a specific account (e.g., an administrator account), and requires the transfer of assets according to specific issuance rules.
Digital asset query
The user queries the number of digital assets under a given account through a digital asset contract on the blockchain as needed. This operation is essentially the access and resolution of specific data in the blockchain ledger. Asset querying is the most fundamental function in digital asset applications, as users always want to know the quantity information of various types of assets in their own accounts. In the inquiry, the implementation of the inquiry function is different from the analysis rule of the inquiry result due to the difference of the digital asset types, and the specific method comprises the following steps:
for interchangeable digital assets, designating an account name, inquiring through a digital asset contract, wherein the inquiry result is digital asset quantity information under the account;
for the non-interchangeable digital assets, an account name and a digital asset ID are designated, inquiry is carried out through a digital asset contract, and the inquiry result is binary information of whether the digital assets corresponding to the digital asset ID exist under the account;
and for part of interchangeable digital assets, designating an account name and a digital asset subclass ID, inquiring through a digital asset contract, wherein the inquiry result is the quantity information of the digital assets related to the digital asset subclass ID corresponding to the account.
Digital asset transfer
The user transfers the digital assets under his account to other accounts of the same blockchain via a digital asset contract. Which is essentially an update of the digital asset contract's digital asset quantity information of the user (representing a transfer of ownership of the asset) under the authorization of the user. Digital asset transfer is another of the most basic functions in blockchain digital asset applications, and is a technical guarantee of digital asset liquidity.
Increase in digital assets
During the running process of the digital asset contract, the digital asset manager transfers the digital assets to the account of the target user from the preset specific account according to the requirement. Technically, digital asset accreditation and digital asset issuance are indistinguishable and are the process of transferring assets from a digital asset contract account or an administrator account to a user account. The difference between the two is that the release is typically made at contract creation time, while the enhancement can be made at any time.
Freezing of digital assets
The digital asset manager closes its asset transfer and asset destruction functions for a specified account for a certain period of time via a digital asset contract. Digital asset freezing is often used in application scenarios where asset proof is required, such as recharge, mortgage, and transaction. In practical applications, the digital asset freezing may be accomplished by adding a frozen state to the corresponding digital asset, or by sending the digital asset to a time-locking contract that automatically transfers the digital asset to the original account after the expiration of the locking time.
Digital asset destruction
The user or the digital asset manager destroys a certain number of digital assets in the user account in an appointed destruction mode through the digital asset contract, so that the digital assets exit the circulation field. Asset destruction is commonly used for stock-like digital assets. In practice, asset destruction may be accomplished by transferring the asset to an unavailable account, which is essentially a special transfer action.
Digital asset authorization
A user authorizes the use of a certain amount of digital assets in their account to a third party account, enabling them to host the authorized digital assets. The asset authorization process does not have a substantial transfer of assets occurring, but rather provides a commitment to use the asset, which the commitment custodian can use a portion of the granted digital asset in the authorizer account to enjoy the services or benefits of the asset representative after authorization.
Although illustrative embodiments of the present invention have been described above to facilitate the understanding of the present invention by those skilled in the art, it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all matters of the invention which utilize the inventive concepts are protected.
