Logistics data publicity method and system based on block chain and IPFS

Abstract

The invention discloses a logistics data publicity method and system based on a block chain and an IPFS, and relates to the technical field of data storage. The method comprises the following steps: selecting an IPFS as a technology for sharing files and data; storing files and data in nodes of the mechanism of the interstellar file system based on the block chain through an API. randomly storingcell blocks in several to hundreds of IPFS nodes according to the IPFS synchronization principle of node data, after files and data are encrypted and subjected to hash segmentation; through an IPFS system, automatically segmenting the file into small file blocks by hash, archiving the small file blocks into the IPFS system, and generating a unique hash value; and publishing a hash value listcorresponding to hash values of files and data of all the mechanismsin a mainstream channel and an industry authority mechanism. By adopting a block chain technology and an interstellar file system storagetechnology, the method is applied to logistics file and data storage, the data privacy of related parties is ensured, meanwhile, the physical storage expenditure is saved, and the expenditure of manpower management is saved.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a method for publicizing logistics data based on blockchain and IPFS, and a publicity system for logistics data based on blockchain and IPFS.

AI Technical Summary

Problems solved by technology

[0014] The purpose of the present invention is to provide a method and system for publicizing logistics data based on blockchain and IPFS. By adopting blockchain technology and the storage technology of the interstellar file system, it is applied in logistics files and data storage, and solves the existing problems. The current file and data management systems in logistics, production, learning, research, and supervision have problems such as outdated management methods, inability to share and coordinate, difficult retrieval, data loss, and high storage costs.
