Abstract

Modern technologies, supported by the Internet of Things (IoT), have imparted great speed in data sharing between connected devices across several domains of the economy. The Internet of things transformed data collection activities with its creation of smart homes and cities, healthcare, transportation environments, and industrial automation. The fact that there are multiple resource-limited devices, and continuous data transfer of sensitive information has turned the IoT devices less secure and susceptible to threat and leakage of privacy. Modern IoT systems demand lightweight decentralized algorithms that do not exist but are necessitated. The Proof-of-Work concept of the blockchain systems requires high expenditure on energy that eliminates its functioning on processing-limited devices. The energy-consumption-concept that is inherent in the proof-of-work concept makes it difficult to implement in the processing-limited devices. Comparative research develops an indispensable framework, that outlines advantages and disadvantages for researchers and practitioners. This research plunges into investigation of blockchain frameworks implemented for the IoT systems. Scientific approach to IoT privacy threats within existing privacy frameworks requires testing mechanisms to prevent unauthorized access and unintended modifications and data leaks. Modern ways of analyzing provide a variety of recommendations since the analysis presents both positive and negative aspects offering valuable insights for researchers as well as professionals. The review examines the blockchain systems that protect the IoT devices and their confidential information. The study introduces BLOX-IoTs (Blockchain lightweight optimization extensibility for IoT security), which aims to ensure full user privacy while enabling IoT devices to verify information reliability through the use of Blockchain technology. The research offers IoT infrastructure with a scalable solution for protection strategies.

Keywords: BLoX-IoTs, efficient frameworks, internet of things, IoT security, lightweight blockchain, privacy enhancement, resource efficiency, secure communication
