The Intersection Of Blockchain And The Web Of Things: A Systematic Mapping Study

Abstract

The integration of blockchain technology with the Web of Things (WoT) has the potential to enhance security, privacy, and interoperability, opening new opportunities for various industries. This systematic mapping study provides a detailed overview of the current state of research in the field of WoT based on blockchain technology. We analyzed 20 papers published until early 2023, classifying them based on their research objectives, methods, and contributions. Most of these papers targeted security and privacy concerns, emphasizing areas such as digital twins, access control, and data sharing. Additionally, topics such as interoperability, scalability, and governance were addressed. A significant number of papers propose the use of blockchain for structural health monitoring and food quality assurance, while others examine the integration of blockchain with wireless sensor networks and e-commerce. Although blockchain-based WoT has garnered increasing attention, further research is required to overcome challenges in scalability and interoperability, and to realize the full potential of this technology.
