Abstract

The embodiment of the invention provides a block chain-based data sharing method and apparatus and an electronic device, wherein the block chain-based data sharing method is applied to a data requester, and comprises the following steps of generating a data query message, wherein the data query message comprises a target data attribute, and the target data attribute is the data attribute of data to be acquired by the data requester; through the data query message, querying a data index record in a regional chain network, and determining a data holder sequence corresponding to the target data attribute; sending a data request message to a first data holder in the data holder sequence, the data request message being used for requesting data corresponding to the target data attribute; and receiving a target data model and target data returned by the last data holder in the data holder sequence. According to the invention, the safe and effective data sharing is realized.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based data sharing method, device and electronic equipment. Background technique [0002] Data sharing generally refers to the practice of providing data held by data holders to other parties for further analysis and utilization, especially in the field of scientific research, which has a long history. Data sharing is considered a key method integral to scientific research. At the same time, the issue of privacy protection in the process of data sharing has also attracted widespread attention. Different countries have legislation to ensure the legal use of data and avoid compromising the privacy of sensitive data in the process of sharing. [0003] Existing data sharing methods can be as figure 1 As shown, data holder A sends its own encrypted data A to the third-party data manager; data holder B sends its own encrypted data B to the third-party data man...
