Abstract
The rapidly growing IoT devices pose significant security challenges due to their decentralized nature, limited computing power, and reliance on centralized security models.

(It has revolutionized industry, turning everyday objects into interconnected devices)

Blockchain technology has emerged as a potential solution due to its decentralized, immutable, and transparent nature, providing enhanced security for IoT environments.

This study proposes a blockchain-based security strategy aimed at mitigating security risks in IoT networks.

This study demonstrates that blockchain technology can significantly improve the security of IoT networks by addressing the limitations of traditional and centralized security models.

Blockchain and IoT devices can be combined and improved by using smart contract device authentication, data integrity verification, and results access, authentication speed, energy efficiency, and more suitable key latency. IoT environments.

Using lightweight consensus mechanisms, this system can maintain low energy consumption while processing high-volume transactions in real time.
