Blockchain-Based Traceability Method - A Review

Effective output optimization in various industries requires precise monitoring of all processes and data involved. To facilitate further optimization, information must be easily accessible and traceable. While data traceability can be achieved using various technologies, some methods may have limitations, such as a lack of real-time monitoring or difficulty integrating with existing systems. In recent years, the emergence of blockchain technology has enabled new possibilities for data traceability. Blockchains are composed of blocks of hashed data that are linked to earlier blocks, providing a reliable means of tracing data. This paper explores the fundamental concepts of blockchain technology and its features, highlighting the limitations of traditional traceability systems and the advantages offered by blockchain. Then, this paper reviews existing literatures to provides a comprehensive overview of blockchain-based traceability methods, offering insights into their applications, benefits, challenges, and future prospects.
