Blockchain Technologies App to Enhance Data Exchange Safety in Internet of Things Networks Using Wireless Communications

Abstract

The abrupt surge of Internet of Things (IoT) networks that are wirelessly connected by the medium of 5G and 6G communications has disrupted the data exchange processes of industries. Centralized IoT networks are prone to tampering and harmful access via the medium of security attacks. Decentralized, tamper-evident, and transparent blockchain technology is a best-fit solution via the medium of securing IoT data exchanges. This paper explores blockchain application in IoT security in the areas of light weight consensus algorithms, decentralized authentication, and new interfacing to wireless networks. A Python simulation demonstrates an augmented blockchain platform for storage of data securely in IoT by applying data encryption, scalability enhancement, and visualization of sensor data, revealing its applicability in resource-constrained environments. Scalability, energy, and interoperability issues are resolved through actionable recommendations towards further development.
