Abstract

The invention discloses a method and device for querying recycled articles on a block chain, and the method comprises the steps that a user scans a two-dimensional code of a sold finished product through a client; wherein the finished product is obtained by recycling waste materials and processing the waste materials in a factory; the client acquires recycling process data corresponding to the finished product from a block chain according to a query instruction in the two-dimensional code, wherein the recovery process data comprises article recovery data, article processing data, article delivery data and article sales data. According to the method, after all the recycling process data of the article is linked, query is performed on the block chain, so that user query is more convenient, and the user experience of querying the recycling process data is improved.

Description

technical field [0001] The present application relates to the technical field of block chain, and in particular to a method and device for querying recycled items on the block chain. Background technique [0002] At present, blockchain, Internet of Things and artificial intelligence are listed as the three major technologies of future technology. Blockchain technology is based on a decentralized peer-to-peer network, using open source software to combine cryptography principles, time series data and consensus mechanisms to ensure the coherence and continuity of each node in the distributed database, so that information can be verified instantly and can be Traceable, but difficult to tamper with and unshielded, thus creating a shared value system of privacy, efficiency and security. [0003] In the field of article recycling, the entire recycling chain includes article recycling, factory processing, factory reproduction, and new article sales. When the information of these ...
