【Abstract】Data provenance is a basic requirement for trusted data management in the era of big data. Before the emergence of blockchain technology, data provenance mainly used a centralized database to store data records, log records, etc., to facilitate subsequent audit tracking, but database has the security problem of data tampering. After the emergence of blockchain technology, researchers have conducted a lot of research on trusted data provenance in the Internet of Things (IoT), product supply chain, medical health and other fields based on the characteristics of blockchain decentralization, tamper resistance, and traceability,etc., to ensure the security and trustworthiness of data provenance results. This paper will sort out the research on the use of blockchain technology for data provenance in different fields in recent years, and analyze the similarities and differences between existing blockchain based data provenance methods as a whole. Finally, the possible challenges in data provenance based on blockchain technology are pointed out and the possible solutions are given.
