Blockchain for Cybersecurity in Edge Networks

The blockchain is one of the most promising and artistic cybersecurity solutions. It has been practiced in a variety of reinforcements, including healthcare, transportation, and Internet of Things (IoT) applications. However, blockchain has a colossal scalability challenge, limiting its ability to control services with high transaction volumes. Edge computing, on the other hand, was designed to allow cloud services and resources to be deployed at the network's edge, although it now faces issues in terms of decentralized security and management. The unification of edge computing and blockchain within one solution jar provides a vast scale of storage systems, database servers, and authenticity computation toward the end in a safe fashion. This article provides an overview of the secure IoT framework, paradigms, enablers, and security problems of combining blockchain and intelligent edge computing. Finally, broader viewpoints for future research directions are investigated.
