Product circulation tracking method and system based on block chain

Abstract

The invention provides a product circulation tracking method based on a block chain. The method comprises the steps that data information generated in product circulation operation links is collected,graded, encrypted and packaged to generate blocks; whether the information of the blocks is true is verified through authenticated manager node workload proof; the blocks passing verification are stored into the block chain, and meanwhile keys are stored in product packages; and the data information of the products on the block chain in different circulation links is found and decrypted through corresponding key information in the product packages, so that the purpose of tracking and tracing all the circulation links is achieved. The invention furthermore provides a corresponding system. According to the product circulation tracking method and system based on the block chain in the embodiment, the whole production and circulation process of the products can be monitored, and source tracing can be performed no matter which link has a problem; moreover, the network system divides product information into three different levels, supervision is realized hierarchically, and information security is guaranteed; and meanwhile, a strict verification process is available for information input, multiple management nodes cooperate mutually, a single management node cannot impose a great influence on the whole system, and therefore the distributed network tracking system has high practicability in terms of product monitoring and is suitable for large-range popularization.

Description

technical field [0001] The present invention relates to the field of network product information tracking, in particular to a blockchain-based product circulation tracking method and system. Background technique [0002] Blockchain provides a decentralized credit establishment paradigm that does not require trust accumulation. The essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and in a distributed structure. It uses data blocks to replace the current dependence of the Internet on central servers, so that all data changes or transaction items are recorded in a cloud. On top of the system, the self-certification of data in data transmission is theoretically realized. In a far-reaching sense, this surpasses the information verification paradigm that needs to rely on the center in the traditional and conventional sense, and reduces the cost of establishing global "credit". This point-to-point Verification will ...
