Commodity data information collection system and method based on block chain technology

The invention discloses a commodity data information collection system based on a block chain technology, and the system comprises a code scanning module, the lower layer of the code scanning module is connected with a sub-server, the lower layer of the sub-server is connected with a main server, the lower layer of the main server is connected with a block chain frame, and the block chain frame internally comprises a data layer, a network layer and a consensus layer. The data layer encapsulates data blocks for data encryption and timestamp, the network layer performs data distributed networking, data propagation and data verification, and the consensus layer encapsulates various consensus algorithms of network nodes. By arranging a series of structures, commodity data information can be accurately collected, price information can be edited in a unified mode after collection, and data information leakage caused by network attacks is not prone to occurring. 本发明公开了一种基于区块链技术的商品数据信息收集系统，包括扫码模块，所述扫码模块下层连接有子服务器，所述子服
