Description

A blockchain-based tamper-proof system for renewable resource recovery data

technical field

The invention relates to the field of recycling of renewable resources, in particular to a blockchain-based anti-tampering system for recycling data of renewable resources.

Background technique

The characteristics of the renewable resources industry are that the back-end waste recycling enterprises are large, standardized, and concentrated, while the front-end recycling enterprises are small, scattered, and chaotic, and the degree of informatization is very backward. At present, the preferential tax policies for the renewable resources industry are only aimed at the production and processing links, and a large number of recycling companies cannot enjoy the policies. In order to solve problems such as input cost identification, invoices, and value-added tax income tax, some regional government departments provide industrial support financial preferential policies, but due to the huge demand of the industry , the lack of effective supervision means leads to problems such as false transactions and out-of-control invoices, and the lack of effective protection of transaction bill data. There are problems of key bill data being tampered with and stolen in front-end recycling companies.
