Data processing system based on block chain

Abstract

The invention provides a pesticide database processing system based on a block chain technology. The pesticide database processing system comprises a conversion center, the conversion center is connected with a client, connected with one or more databases and connected with one or more blockchain nodes through blockchain adapters, and the conversion center manages mapping relations between the databases and the blockchain nodes for data writing. The invention further provides a database backup and recovery method based on the block chain technology. According to the invention, the blockchain technology is used; the characteristics of tamper resistance and permanent storage are utilized; meanwhile, the data is distributed in the blockchain nodes; the overall failure caused by the failure ofthe central point is avoided, so that the safe and reliable database backup is realized, most organizations can properly control the cost and effectively deploy backup schemes in the existing environment, the requirements of the organizations can be met, and the method and the system can be universally implemented and have very wide application scenes.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to a block chain-based data processing system. Background technique [0002] In recent years, blockchain has been widely used in industry, agriculture, transportation, shopping malls, banks, public security and other fields. It is one of the important means of modern management and monitoring, which greatly improves management efficiency and automation level. Generally speaking, the sharing and inquiry system consists of the following parts: producers, processors, regulators, transporters, retailers, consumers. [0003] With the continuous development of the Internet, as well as the development of information technology and network technology, people's demand for data sharing is becoming more and more intense. In today's global big data environment, people gradually hope to obtain information from all aspects of society through the mechanism of data sharing. As far as...

Problems solved by technology

[0004] However, in the current data processing system related to pesticide products, it is generally simple to integrate and push the information of the various processes of pesticides, including production and sales, to the data processing requester. There is no effective guarantee based on the logical relationship of each process. Form better traceable data processing, and secondly, the consistency and security of data in the process of data processing and sharing cannot be guaranteed
