The embodiment of the invention discloses an industrial data tracking method based on a block chain. The method comprises the following steps: acquiring a processing equipment number and a processing process number of an industrial processing node; performing Hash calculation on the processing equipment number, the processing process number and the processing data to generate a first Hash value; packaging the processing data, the processing equipment number, the processing process number and the first hash value, and encrypting the packaged data to obtain first encrypted data; verifying the processed data through the verification node, and obtaining a verification number of the verification node after the verification is passed; performing hash calculation on the verification number and the processing data to generate a second hash value; packaging the processed data, the verification number and the second hash value, and encrypting the packaged data through a private key of the verification node to obtain second encrypted data; the first encrypted data and the second encrypted data are uploaded to the block chain, and after the first encrypted data and the second encrypted data are decrypted, tracking of the specified industrial data is achieved.
Description
technical field [0001] This specification relates to the field of blockchain technology, in particular to a method, device, device and medium for tracking industrial data based on blockchain. Background technique [0002] With the rapid development of economy and society, the advancement of computer network technology, and the rise of industrial manufacturing, human society is experiencing the fourth industrial revolution characterized by "the integration of information technology and manufacturing". The volume of industrial data is large, the high-frequency data of a large number of machines and equipment and the continuous influx of Internet data, the data set of large industrial enterprises will reach PB level or even EB level, so industrial big data technology emerges as the times require, big data processing technology It has also gradually matured, and the importance of data security and tamper resistance has gradually emerged. [0003] There are three main sources of...
