Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
The terms "first," "second," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the order of such use may be interchanged under appropriate circumstances such that embodiments of the invention described herein may be practiced in other orders than those illustrated or described herein.
Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, 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.
The node referred to in the embodiment of the present application may be understood as an abstract machine that responds to an external specific trigger condition and performs state conversion according to a certain rule, and may be a device that can be networked according to application software, such as a mobile phone, a tablet computer, a palm computer, a personal PC, and the like.
The metadata format in the present application may be any one of a json format, an HTML format, a binary format, and a base64 format; can be set according to actual requirements. This will be briefly described below.
JSON (JavaScript Object Notation) is a lightweight data exchange format. It stores and represents data in a text format that is completely independent of the programming language, based on a subset of ECMAScript (js specification set by the european computer association). The compact and clear hierarchy makes JSON an ideal data exchange language. The network transmission method is easy to read and write by people, is easy to analyze and generate by machines, and effectively improves the network transmission efficiency.
HTML, known as hypertext markup language, is a markup language. The document format on the network can be unified through the labels, so that the scattered Internet resources are connected into a logic whole. HTML text is descriptive text consisting of HTML commands that can specify words, graphics, animations, sounds, tables, links, etc.
Binary files contain files of data or program instructions written in ASCII and extended ASCII characters. Computer files are basically divided into two types: binary files and computer programs such as ASCII (also called plain text files), graphic files, and word processors belong to the binary files. These files contain special formats and computer code. ASCII is a simple text file that can be read with any word processing program.
Base64 is one of the most common encoding methods for transmitting 8-Bit byte codes on a network, and Base64 is a method for representing binary data based on 64 printable characters. RFCs 2045-2049 can be viewed, above which is the detailed specification of MIME. Base64 encoding is a binary to character process that may be used to convey longer identification information in the HTTP environment. Encoding using Base64 is not readable and requires decoding before reading. Base64 is widely used in various fields of computers due to the above advantages, however, since more than two "symbol-like" characters (+,/, ═ are included in the output content, various "variants" of Base64 have been developed in different application scenarios. To unify and normalize the output of Base64, Base62x is considered an unsigned, improved version.
The application discloses a processing method capable of changing NFT works. As shown in fig. 1, the method is applied to a server, and the method includes steps S101-S105.
S101, receiving the NFT works sent by the user equipment.
S102, organizing the NFT works into metadata and locally storing the metadata.
S103, sending the storage address of the metadata and the metadata to any blockchain node in a blockchain system, so that the blockchain node allocates non-homogenization certification NFT for the storage address of the metadata and the metadata.
S104, receiving the non-homogeneous certification NFT sent by the block chain node, establishing a mapping relation between the non-homogeneous certification NFT and the metadata and the storage address of the metadata, and storing the mapping relation into a local database.
S105, sending the homogenization evidence NFT to the user equipment.
In one example, the metadata includes at least one attribute of the NFT work, and the attribute of the NFT work includes at least one attribute value; any attribute value of the NFT work comprises selected or unselected two operation states.
In one example, as shown in FIG. 2, the method further includes steps S201-S204.
S201, receiving a modification request of the NFT work sent by a user through the user equipment, wherein the modification request of the NFT work comprises a state of modifying one or more attribute values.
S202, according to the non-homogenization evidence-based NFT in the NFT work modification request, locally inquiring a storage address of the metadata from the server.
S203, according to the modification request of the NFT works, changing the attribute state of the NFT works in the metadata.
And S204, sending the NFT works after the attribute state is updated to the user equipment so as to be conveniently displayed to the user by the user equipment.
At this time, it should be noted that, the modification of the NFT work by the user actually modifies the attribute state of the NFT work; therefore, the modified NFT work is only displayed to the user to be different from the NFT work before modification, because the NFT work before and after modification is only in different attribute states, but still is the same NFT work, and therefore, only the storage in the local database of the server is needed, and the NFT work in the blockchain does not need to be updated.
In other words, the combined storage architecture of the block chain system and the server is adopted, and the storage of the modifiable NFT works is met.
In one example, an author of the NFT work owns the modification rights of the NFT work; when the creator of the NFT work sells the NFT work, the modification right of the NFT work is sold together, so that a purchaser of the NFT work has the modification right for modifying the NFT work.
The type of NFT work is not limited in this application, and for ease of understanding, this application describes from a picture type of NFT work. The size, color, hue, saturation, etc. of the picture can be set as the attributes of the picture by the creator, and how to set these attribute values or select those attribute values for setting is decided by the creator.
In one example, the NFT work is a variable color chameleon pictorial work; when the user moves the chameleon painting from the green bamboo forest background to the yellow ginkgo leaf background, the user modifies the selected green color attribute state into unselected state and modifies the unselected yellow color attribute state into selected state through the user equipment;
when the user moves the chameleon pictorial work from a shrub background to a phoenix tree background, the user modifies the selected smaller-size attribute state into unselected state and modifies the unselected larger-size attribute state into selected state through the user equipment; wherein the content of the first and second substances,
the chameleon pictorial representation comprises a plurality of color attribute states and a plurality of size attribute states.
The method and the device can store the NFT works with changing requirements, can improve the creation experience of the NFT works which can be changed by a creator, further promote the wide application of the NFT technology, and further increase the application scenes of the block chain technology.
Further, the present application is directed to NFT works demanded by alterations; compared with the NFT works stored in a fixed manner, the NFT works in the change requirement are dynamic works and can be set according to the requirements of users. However, this setting is changed within the range of the setting from the beginning of the NFT work creator, and it is not possible to increase or decrease a certain attribute, and it is only possible to select the attribute state, and it is more intended by the creator. The storage of the change demand NFT works is suitable for creators of dynamic NFT works.
The application also discloses a processing device capable of changing NFT works. As shown in fig. 2, the apparatus is a server, and the apparatus includes a receiving unit, a processing unit, and a transmitting unit.
The receiving unit receives the NFT works sent by the user equipment;
the processing unit organizing the NFT work into metadata and storing the metadata locally;
the sending unit sends the storage address of the metadata and the metadata to any blockchain node in a blockchain system, so that the blockchain node allocates non-homogenization pass-through (NFT) for the storage address of the metadata and the metadata;
the receiving unit receives the non-homogeneous certification NFT sent by the block chain node, and the processing unit establishes a mapping relation between the non-homogeneous certification NFT and the metadata and the storage address of the metadata and stores the mapping relation in a local database;
the sending unit sends the homogenization certification NFT to the user equipment.
In one example, the metadata includes at least one attribute of the NFT work, and the attribute of the NFT work includes at least one attribute value; any attribute value of the NFT work comprises selected or unselected two operation states.
In one example, the receiving unit receives a modification request of the NFT work sent by a user through the user equipment, wherein the modification request of the NFT work includes a state of modifying one or more attribute values;
the processing unit locally queries a storage address of the metadata from the server according to the non-homogenization evidence-passing NFT in the modification request of the NFT works;
the processing unit changes the attribute state of the NFT work in the metadata according to the modification request of the NFT work;
and the sending unit sends the NFT work after the attribute state is updated to the user equipment so as to be conveniently displayed to a user by the user equipment.
The method and the device can store the NFT works with changing requirements, can improve the creation experience of the NFT works which can be changed by a creator, further promote the wide application of the NFT technology, and further increase the application scenes of the block chain technology.
