Research on Consistency Tracing Technology of Dispatching Control Model Data based on Blockchain

In the era of big data and artificial intelligence development, data has become an important asset. Open data ecology has become an inevitable choice to promote business success. In the process of data open sharing, data provenance technology can supervise the data sharing path among multiple entities, and protect the interests of data owners. This paper proposes a data provenance technology for dispatching and control data based on blockchain. Firstly, a data provenance model is designed based on blockchain, which describes the provenance process of dispatching and control model data.Secondly, the distributed ledger of blockchain is used to record the data sharing path described by the data traceability model.Finally, the automatic implementation of provenance process is realized by using smart contract of blockchain.
