Data is a novel production element, and the digital economy taking the data as a key element becomes a new engine for industrial development. Technical researches on resource integration and security protection of data, management of data, ownership, privacy protection, copyright protection and the like have become important in recent years.
The experimental data is an important data resource, and the corresponding experimental conditions, experimental environment, experimental scheme and acquired experimental result data play an indispensable role in generating important experimental results and forming important research ideas. Particularly, when the experimenter obtains an effective experimental result, the corresponding experimental conditions, experimental environment and experimental scheme are reflected by the design value of the experimenter. In addition, for experimental data generated in a certain subject field or industry, the experimental data may also have application value in other subject fields or industries, and effective sharing and exchange of data are also required to be realized.

Non-homogeneous Token (NFT) is an irreplaceable and unique Token. The special properties of non-homogenous evidences allow for the use of physical assets, such as art, house contracts, etc., that are typically associated with non-replaceable items of actual value to prove ownership of the items. The NFT, which is derived based on the blockchain technology and contains a plurality of rules and information, has an irreproducible and inseparable unique digital encryption right certificate, can be used to indicate the right attribution of a certain digital article, and is implemented by determining the right of pure digital content. By utilizing scarcity, traceability and non-tamper-ability, the digital content corresponding to the non-homogeneous certificate can be stored and circulated on a block chain, and the circulation of the digital assets is enhanced by setting a profit sharing mode in an intelligent contract, and a profit guarantee and intellectual property protection mode is provided while the copyright of the digital assets is protected.
