BIG DATA COMPUTING METHOD AND SYSTEM BASED ON BLOCKCHAIN AND FOG COMPUTING

WIPO Patent Application WO/2019/196397

A1

Provided are a big data computing method and system based on a blockchain and fog computing. The method comprises: an information publication node publishing on a blockchain network a smart contract carrying a data resource directory; a data node publishing data information on the blockchain network; a big data computing requirement node generating, according to the data information and the smart contract, a big data computing smart contract carrying requirement information and a storage location; a fog computing resource node selecting a resource node from a fog computing network and publishing a corresponding smart task contract on the blockchain network; a verification node triggering a target data node according to the smart task contract, the requirement information and the data information; the target data node sending target resource data to the selected resource node; and the selected resource node computing the target resource data according to the requirement information so as to generate a computation result, and storing same at the storage location. By means of the technical solution of the present invention, the leakage of resource data of a data node via a big data computing requirement node can be prevented.
