Abstract

The invention provides a block chain-based data storage method and device, equipment and a storage medium. The block chain deploys an intelligent contract for managing data assets, and the method can comprise the steps of obtaining a data evidence storage transaction initiated by a data holder; wherein the data storage transaction comprises to-be-stored user data. The user data comprises authentication data generated after the authentication mechanism performs user authentication on the user. And in response to the data storage transaction, a data asset generation logic included in the smart contract is called, a data value is marked for the user data, and associated storage is carried out on the user data marked with the data value and user data marked with the data value generated after the user is authenticated by other authentication mechanisms, and data assets corresponding to the user are formed.

Description

technical field [0001] This application relates to computer technology, in particular to a blockchain-based data storage method, device, device and storage medium. Background technique [0002] After authenticating the user, the certification authority can form authentication data related to the user. These authentication data may include information closely related to the user. [0003] Taking the above-mentioned certification body as a vocational certification body as an example, users can obtain vocational skills training provided by various vocational training institutions. After the user graduates, the certification authority can generate certification data for the user that can certify that the user has relevant skills. The above-mentioned authentication data may include data information such as user identity information, age, occupational skills, and education level. [0004] When a user is associated with multiple different authentication agencies, the relationshi...
