Description
Technical Field
The application relates to the field of internet data processing, in particular to asset data processing based on a block chain network.
Background
Enterprises typically have a large number of assets formed from past transactions or issues that the enterprise owns or controls and is expected to bring economic benefits to the enterprise. For example, assets can be classified by liquidity as liquidity assets, long-term investments, fixed assets, intangible assets, and other assets. The energy production brings economic benefits and depends on ownership of resources A; B. the ability to use ownership, i.e., the right to earnings generated based on the disposition of assets. However, in the internet mode, it is difficult to change the generalized assets into commodities which are moved from off-line to on-line, and since the commoditized expressions of the assets are not uniform, the circulation flow of the assets across platforms, industries and regions is restricted, and it is difficult to bring economic benefits to enterprises and regions.
The types of assets are extremely complex and difficult to unify according to a unified standard. Only by taking intellectual property as an example, China currently has a large number of intellectual property assets in a deep sleep state, and the types of the intellectual property assets are relatively limited, such as patents, trademarks, copyrights and the like. Even these types of assets can only be traded within one platform, as they follow different trading flows and rules. That is, if two transaction agents are located on different platforms, it may be difficult to implement a transaction due to the non-uniform standards and rules between the platforms. If the assets of different kinds are changed into the digital assets of unified standard in a digital mode, the digital asset transaction can break the limit between platforms.
Therefore, how to process assets to become high-frequency transaction objects is a difficult problem to be solved urgently, which is beneficial to promoting the circulation of the assets through a mode of participating in transactions by the public, and further enables natural resources to be more reasonably organized and utilized.

Detailed Description
From an economic and technical point of view, the organization and utilization efficiency of natural resources in human society depends on the needs of human beings. From the perspective of assets, if the assets in the general sense of having use value and generating economic benefit can be converted into public demand and high-frequency transaction from meeting the demands of the masses and low-frequency transaction, the method is favorable for accelerating the circulation of the assets and enables the organization and utilization efficiency of natural resources to reach a higher level. The method is a key link for converting various assets like fixed assets and intellectual property assets into digital assets capable of online transaction.
Digital assets are typically non-monetary assets in the form of electronic data, which can only be made highly fluid by converting assets in a general sense to digital assets. Assets can be economically profitable through trading, the key being that they have a use value, and therefore each category or each particular asset has its own objectively available attributes that can be used.
At the heart of the new form of trading resulting from the digitization of assets is the right standardized trading of digital assets. Compared with the conventional property ownership transaction, partial ownership (permission) and right-of-return transaction are increased, and in addition, new transaction content can be added according to different types of properties. For example, for copyright, a disposal right transaction, such as an exercise right transaction, or the like, may be added.
The method provided by the application is characterized in that the digital asset data packets with higher frequent transaction effects are respectively and correspondingly generated for different types of assets by utilizing different types of assets, namely, the number of commodities which can be formed is increased so as to be more easily transacted. The digital asset data package is often referred to simply as a digital asset package, and in some instances is also referred to as an asset data package.
As shown in fig. 1, an embodiment of the present application provides a method for generating a digital asset pack. Assets as resources that can bring economic benefits to enterprises need to be owned and used with usage rights or disposal rights, so that economic benefits can be created. Thus, the nature of an asset and its bringing economic benefits lies in the possession and use of its rights, such as the right to earning, ownership, and disposal, among others. Therefore, the asset digitization consists in the digitization of the rights of the asset, and the digitization of the asset, i.e. the rights of the digital asset, is the object of the transaction, and therefore, the transaction of the digital asset can also be said to be the right transaction. The flow chart of the embodiment shown in fig. 1 embodies the idea. The method specifically comprises the following steps:
s100: selecting at least one tradeable right from a set of tradeable rights corresponding to a given asset, based on the category of the given asset;
in this embodiment, the type of the given asset is not limited to multiple types including patent rights, copyright rights, bad assets, bulk goods, or enterprise equity, as can be seen from fig. 2, according to different types of given assets, rights items included in the corresponding tradable right sets may be different, and in general, all rights items are divided into earnings, ownership rights, and disposition rights, one or more of the earnings, ownership rights, and disposition rights may be included in the tradable right sets, and the number of each type of rights (for example, earnings) is not limited to one or more, and therefore, the tradable right sets are composed of rights items corresponding to different types of digital assets. The following is illustrative of several common categories:
for a patent, the corresponding tradable rights items include: application rights, ownership rights, exclusive permissions, general permissions, sub permissions, cross permissions, and the like, which may include one or more;
for copyright, graphic works such as written works, dictation works, music, drama, music art, dance works, fine arts, photographic works, movie and television, video works, engineering design, product design drawings and descriptions thereof, maps, schematic diagrams, and the like are mainly targeted. The corresponding tradable rights items include: copy right, issue right, lease right, exhibition right, show right, broadcast right, information network transmission right, shooting right, recomposition right, translation right, assembly right, etc.;
for bad assets (banking, business, personal), large commodities (commodity, equity) and enterprise equity (stock, OTC), the corresponding tradable rights items primarily include ownership rights.
The above rights are only examples and rights specific to them may also be established based on a particular digital asset.
In step S100 of this embodiment, the purpose of selecting at least one tradable right in the tradable right set is that, since the combination form of multiple right items can be arbitrarily selected in one set, each different right item combination can be traded as a tradable commodity alone, which is equivalent to constructing a basic logic: digital asset (given asset) = { right to earning, ownership, right to dispose of the asset }, while digital asset commodity for trading = subset of digital assets.
For example, in an example shown in fig. 3, a digital asset a of a movie work has five independent revenue rights and two license rights to be sold, which are denoted as a { x1, x2, x3, x4, x5, y1, y2}, and then the digital asset can be separated into tradeable commodities with the number = C7 1+C7 2+……+C7 7=7+21+35+35+21+7+1=127。
It can be seen that the above-mentioned digital asset a can be evolved into 127 tradable commodities for trading at most, and if other elements are added, such as a regional element (defining a certain permitted use region), more commodities may be formed. If each commodity corresponds to a group, obviously, the mode enables more choices for the buyer, and even possibly negotiates new commodities with the seller on line, the circulated commodity quantity and the buyer data will increase sharply.
Further, in this embodiment, the right item for trading is not limited to the complete right item, but may also include partial right items, such as trading only partial permission right, or defining a period, region, i.e. time-limited ownership, time-limited permission right, income right of a designated place, etc. usable after trading for a certain right item, therefore, in a feasible embodiment shown in fig. 4, the step of selecting at least one tradable right in the step S100 includes:
s110: determining the number of terms of the tradable right for the transaction, which is the number of rights items pre-purchased by the buyer, that is, from the tradable right set, the buyer can select the desired rights items according to the self-demand and put the aggregate of all the desired rights items as the commodity of the transaction to make a purchase demand.
As the previous example, for the set a { x1, x2, x3, x4, x5, y1, y2}, it is first determined which rights are wanted to be traded from x1, x2, x3, x4, x5, y1, and y2, and assuming that x1, x3, x4, x5, and y1 are selected from the set, the finally generated digital asset package only contains the related contents of these five rights, but does not contain the related contents of x2 and y 2.
S120: determining the share of each tradable right, wherein the share is a defined value of each of the aforementioned rights, for example, distinguishing all rights from partial rights, specifically defining a time period, defining a user composition, defining a location range, and the like, which is equivalent to further dividing the rights, and creating a plurality of possibilities for the composition combination of the final transaction product.
Also as in the above example, assuming that the aforementioned sets of x1, x3, x4, x5, y1 have been selected, then in step S120, a presentation share is added to each rights itemOf (2), e.g. S1x1、S2x3、S3x4、S4x5、S5y1 wherein S1-5It can be a percentage, which represents the ratio of partial rights to the total rights, or it can be a descriptive document defining the time period, defining the composition of the user, defining the range of the place.
S200: forming a digital asset package from the tradable right and asset description document, the ownership statement document, and the digital carrier of the asset;
when the right items to be traded are selected and determined, the data related to the right items are packaged together and then published to the blockchain network, so that the data on the chain is complete and traceable, and therefore in this embodiment, the formed digital asset package further includes at least an asset description document, an ownership declaration document, a digital carrier of the asset, and the like corresponding to the tradeable right.
The asset description document mainly includes the relevant introductions to the given asset base case, including for example the asset name, the asset type, etc.
The ownership declaration document at least comprises information of author names, digital asset owner names, right validity periods, ownership modes and the like, wherein the ownership modes can be selected from various options such as originality, purchase, gifts and the like.
The digital carrier of the asset is an entity data packet of the digital asset or an address link for storing the entity data packet, and if the entity data volume of the digital asset is small, the entity data packets can be directly packed and issued together; however, if the digital asset is a large entity data packet, in order to reduce resource occupation and consumption, a better way is to package and issue the address link storing the entity data packet, and after the transaction is completed, the buyer can log in and download the digital asset according to the address in the digital asset packet and the key obtained from the seller.
Thus, in some possible embodiments illustrated in fig. 5, the method provided by the present application will further comprise the following steps:
s201: acquiring an entity data volume of an entity data packet of the digital asset; the entity data volume can be obtained through a query mode and can also be recorded in an asset description document for calling; in addition, the amount of entity data is not limited to a value representing the degree of data duty cycle, and may be in other forms depending on the setting of the threshold.
S202: if the entity data volume is less than the first threshold value, the entity data packets of the tradable right, the asset description document, the ownership declaration document and the asset form a digital asset packet ((r) in the figure); the value of the first threshold is matched with the entity data volume, the value can be established according to experience, industry regulations or other applicability regulations, and the entity data volume is compared with the first threshold to obtain a more appropriate method for forming the digital resource package, so that the forming process and the chain winding process of the digital resource package are quick and efficient, higher safety can be guaranteed, and the operation is facilitated.
S203: if the entity data quantity is larger than or equal to the first threshold value, the tradable right and asset description document, the right declaration document and the address link storing the entity data packet are linked to form a digital asset packet ((C) in the figure).
After the digital resource package is formed, it is necessary to perform the related operations of chaining on the digital resource package:
s300: giving a unique code to the digital asset package, and generating a hash value of the digital asset package comprising the unique code; in order to improve the guarantee of the safety and the credibility of the digital asset package, hash calculation is adopted to enable each digital asset package to have a unique hash value, and further the hash value representing the digital asset package is more difficult to crack through encryption operation; in addition, the unique code given to the digital asset package can be used for facilitating the management of the uplink data package, and can also be used as an identification mark to increase the uniqueness of the digital asset package. In the present application, there is no specific limitation on the formulation rule of the unique code and the hash operation method, and it should be understood that the conventional technical means can be applied to this step.
It should be noted that, in step S300, the digital asset package refers to all the digital asset packages that may be formed, that is, all the aforementioned commodities (digital asset packages) that may be suitable for various purchase demands of the respective buyers, for example, the digital asset a of the film and television works will generate at least 127 (more additional limiting conditions) digital asset packages for uplink distribution, and the corresponding unique codes should also include at least numbers 1-127, and each unique code corresponds to a hash value.
S400: the digital asset package is issued to a blockchain network through the hash value, so that each node in the blockchain network can receive information representing all commodities;
s500: receiving block information fed back by a block chain network;
s600: and recording the block information. Each node packs the received information into blocks and shares it with other nodes.
According to the technical scheme, the method generates the digital asset package by selecting various right item combinations from the tradable right set corresponding to the given asset according to the category of the given asset, and distributes the generated digital asset package to the blockchain network, so that the possibility of product transaction is greatly increased, and the assets in low-frequency transaction are easily converted into the digital assets in high-frequency transaction; in addition, because the formation of the digital asset package and the transaction do not depend on a single platform, the limitation of the platform on the digital asset transaction can be broken, and meanwhile, the digital asset package has higher data security.
FIG. 6 shows a flow chart of a method provided herein under another embodiment;
tradeable rights correspond to and are interdependent with tradeable attributes that an asset has, which reflect the intrinsic properties or parameters that the asset has objectively, and tradeable rights reflect the extrinsic properties or parameters that the asset has objectively, and thus, a tradeable right is determined by a particular asset based on its own objective attributes, which are both the objective attributes that the asset has. For example, for an excavator, the corresponding right to rent, sell, or conditional right to rent, sell is determined by the equipment components it has objectively and its completeness, and if its engine is damaged or malfunctions, the corresponding right to rent, sell will change or be lost. For another example, for an invention patent, the corresponding permission right or conditional permission right is usually based on the premise that the right is in the valid period, and if the invention patent expires or is invalidated, the corresponding permission right or conditional permission right is changed or lost.
Accordingly, the embodiment shown in FIG. 6 provides a method for generating an asset data package based on the objective attributes of the asset itself, comprising:
s101: determining the corresponding tradable right of the asset to form a tradable right set;
unlike the embodiment shown in fig. 1, in this embodiment, in consideration of the objective attribute of the asset, the commodity used for trading may be essentially considered as a tradable right set generated by the tradable right, in this case, the tradable right set has a meaning different from that in the embodiment shown in fig. 1, and the rights included in the tradable right set are not all rights corresponding to the asset, but are objective attributes of the asset itself after the possible changes or losses of the rights, for example, if the object of trading is an invention patent, the method forms the sum of the rights included in the tradable right set, which is the sum of the rights possessed by the invention patent in the current state. It should be appreciated that the embodiment shown in fig. 1 is further derived based on the embodiment shown in fig. 6, the method shown in fig. 6 deals with the totality of rights items objectively owned by an asset, and the method shown in fig. 1 can further screen (further split) the subset of rights items desired to deal within the universe of deals.
