Commodity traceability system based on block chain and big data technology

The invention discloses a commodity traceability system based on a block chain and a big data technology. The commodity traceability system comprises a data collection and query module, a block chaintraceability system and a big data cluster service environment, wherein the data collection and query module is used for acquiring and querying commodity traceability information data, the block chaintraceability system is used for performing uplink storage on commodity core data, and the big data cluster service environment is used for storing commodity details; wherein the commodity core data is a preset core part in the commodity traceability information data, and the commodity details are all data of the commodity traceability information data. Commodity core data is submitted to the blockchain traceability system for uplink storage, malicious tampering is effectively prevented, and the disaster tolerance capability of important commodity data can be obviously improved through decentralized distribution of blo
