Description

Processing method and device for unchangeable NFT (network File transfer) works

Technical Field

The present application relates to the field of block chain technology, and in particular, to a processing method and apparatus for an unchangeable NFT product.

Background

At present, a block chain, the internet of things and artificial intelligence are listed as three major technologies of future technologies. The block chain technology is based on a decentralized peer-to-peer network, and open source software is used for combining a cryptography principle, time sequence data and a consensus mechanism to ensure the consistency and the persistence of each node in a distributed database, so that information can be immediately verified and traceable, but is difficult to tamper and cannot be shielded, and a private, efficient and safe shared value system is created.

Non-homogeneous tokens (NFT) under the etherhouse ERC721 protocol are used to correspond to virtual objects (e.g., pictures, videos, music, etc.) on the internet, and can also be used to associate real objects (e.g., cars, houses, etc.) in real-life scenes. The NFT is unique in the Etherhouse blockchain system, but the work created by the creator has the characteristic of not allowing the change, and how to store the NFT and the characteristics of the work which is not allowed to be changed is crucial.

For example, a work creator creates a picture that is sold as an NFT work. After the NFT work is sold, the ownership of the NFT work in the blockchain system is that of the purchasing user. The purchasing user purchases the picture, but not other pictures, and the picture is not allowed to be modified and not allowed to be changed; if the picture is changed, the changed picture may not be valuable to the purchasing user. The picture includes color, size, pixels, author signature information, and transaction information, all of which need to be stored unalterably.

The above is only for the purpose of assisting understanding of the technical solutions of the present application, and does not represent an admission that the above is prior art.

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 following is an explanation of the terminology involved in this description:

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.

An InterPlanetary File System (IPFS) is an internet underlying protocol for hard disk sharing (a storage network where idle storage space is shared and gains are obtained).

IPFS uses content-based addresses instead of the traditional domain name-based approach, and when a new file is added to the IPFS distributed network, the hash value of the file serves as an index into the IPFS distributed network for the file. If any modifications exist to the file, its corresponding hash value will change. Since the hash value of the file is used to find the file, the file is more secure and more reliable.

Compared with a blockchain network, each node in the IPFS distributed network only stores a part of data, and files in the IPFS distributed network are divided into a plurality of file blocks to be distributed in each node for storage and backup, so that the files are more difficult to attack or tamper.

The present description discloses an NFT work processing method, which is applied to any blockchain node in a blockchain system. As shown in fig. 1, the method includes S101-S103.

S101, constructing the NFT work into metadata, wherein the metadata is used for describing attribute information of the NFT work.

In one example, the metadata includes any one of the following formats: json format, HTML format, binary format, and Base64 format.

In one example, the NFT work includes a picture work and a music work; the attributes of the picture works comprise picture colors and color distribution, picture sizes, picture definition, picture formats and information added by a picture creator, and the music works comprise audio time length, tone colors and information added by a music creator.

It is explained at this time that the NFT work includes not only pictures and music works but also various styles of creative works. In addition, the attributes of the work include information added by the creator, and the added information includes information that the creator is willing to share, such as creation description, creation motivation, creation mode, creation time, and experience after creation.

S102, storing the metadata in the interplanetary file system IPFS, and storing the address of the metadata in the interplanetary file system IPFS in a block chain.

S103, establishing a binding relationship between the storage address of the metadata and a non-homogeneous evidence-based NFT, and storing the binding relationship on a block chain, so that a user can inquire the NFT works according to the non-homogeneous evidence-based NFT or the storage address of the metadata; wherein the non-homogeneous witness NFT uniquely represents the NFT work in a blockchain system.

In one example, a change in any of the NFT work attributes in the metadata causes a change in the storage address of the metadata in the interplanetary file system IPFS; wherein the metadata is fixedly stored in the interplanetary file system IPFS, and a storage address of the metadata is not changed.

It should be noted that, due to the characteristics of the file stored in the IPFS itself, the NFT work may not be changed after being stored in the IPFS. In addition, because the storage address of the NFT work in the IPFS is known only to the creator of the NFT work or the owner of the NFT work, other users cannot modify the NFT work.

In one example, as shown in FIG. 2, the method further includes steps S201-S204.

S201, the block chain node receives a query request of a user for the NFT work, wherein the query request of the NFT work comprises a non-homogeneous certificate NFT bound to the NFT work.

S202, inquiring a storage address of a first interplanetary file system IPFS according to the non-homogeneous certification NFT in the NFT work inquiry request.

S203, comparing the storage address of the first interplanetary file system IPFS with the storage address of the metadata to obtain a comparison result.

S204, if the comparison results are the same, the NFT works are fed back to the user and are not changed; and if the comparison result is different, prompting the user that the NFT works are changed.

The query regarding the NFT work may be performed by the creator of the NFT work, or may be performed by the purchaser or owner of the NFT work. When a user checks the NFT work through a client, the client can be considered to automatically initiate a query process of whether the NFT work is changed or not when the client displays the NFT work; the client may initiate the query process at a preset time interval, and the query process may also be initiated actively by the user.

Further, in one example, as shown in FIG. 3, the method further includes steps S301-S302.

S301, the block chain node receives the NFT work query request sent by a user, and the NFT work query request includes a storage address of the metadata.

S302, the NFT works corresponding to the storage addresses of the metadata are sent to the users.

At this time, for the user, a query mode is provided, that is, the user can query the NFT work through the storage address of the metadata. The user experience is improved. The block chain node may feed back the NFT work stored on the block chain to the user according to the storage address of the metadata.
