A method of data sharing and mining based on blockchain

Abstract

The invention discloses a method for data sharing and mining based on blockchain, comprising the following steps: building a consortium chain, so that the consortium chain includes several enterprise nodes and a computing node; the computing node has a basic operating environment for various algorithms and a computing node. Control process; the enterprise node with the algorithm acts as the transaction initiator, and sends the algorithm code to the computing node; the computing node executes the algorithm code and processes the received data according to the logic of the algorithm; after the processing is completed, the calculation result is saved, and the algorithm and Data, and then return the calculation result to each enterprise node that provides the data for result review; when the review is over, the calculation result is sent to the transaction initiator, and the end of the data transaction is broadcast in the network of the alliance chain. The advantages of the present invention are: based on the block chain, common trust computing nodes are introduced to ensure the safety of the calculation process, and the block chain is introduced into the data transaction, so that the transaction process is trusted by various enterprises, cannot be modified and can be traced.

Description

technical field [0001] The invention belongs to the technical field of data sharing, and in particular relates to a method for data sharing and mining based on blockchain. Background technique [0002] In order to obtain accurate calculation results in a certain professional field, data mining technology needs a calculation model suitable for the problem in this field and a large amount of related data. But often the owner of the algorithm and the owner of the data are not the same company or organization, and even the data that conforms to a certain computing model is distributed in the hands of multiple data owners. For data security and core technology secret protection, both data owners and algorithm owners are reluctant to disclose their core assets to each other, which greatly hinders the application of data mining technology. [0003] The existing blockchain-based data transaction system can better allow low-security data to flow in the consortium chain by checking d...
