How can fog computing architectures influence IoT security measures?

Integrating blockchain technology in Internet of Things (IoT) systems offers enhanced data security and integrity through its decentralized and tamper-proof nature. Transactions recorded on a blockchain are transparent and immutable, ensuring the authenticity of data. However, incorporating blockchain in IoT applications also introduces challenges related to scalability, as blockchain networks may struggle to handle the vast amount of data generated by IoT devices. Additionally, the energy consumption associated with blockchain mining processes can be a concern, especially in large-scale IoT deployments where energy efficiency is crucial. Efforts are being made to address these challenges through advancements in blockchain technology and the development of energy-efficient consensus mechanisms tailored for IoT environments.
