Rakshitha K. Manru, Sowmyarani C.N. . Hierarchical Blockchain-based Security Solutions for IoT Infrastructure: A Technical Review. International Journal of Computer Applications. 186, 47 ( Nov 2024), 1-5. DOI=10.5120/ijca2024924113
The use of Internet of Things (IoT) devices has increased dramatically in this era. An serious lack of storage resources may someday result from the exponential increase in the amount of data produced by these devices. The lack of standardisation in IoT device data format is another issue. This necessitates the requirement for a highly adaptable and scalable system that can securely store the data from these devices while also offering the required protection against several cyberattacks. To address these problems, blockchain offers a practical answer. In addition to offering immutability qualities, its decentralised architecture avoids a single point of failure. It allows for easier coordination between different IoT devices and is more reliable than the conventional centralised solution. However, when employed in Internet of Things applications, the present blockchain systems have constraints regarding security and scalability. It is feasible to build a more effective, safe, and scalable system that can manage the massive amount of data produced by IoT devices by creating a hierarchical blockchain. This study examines the difficulties that current blockchain-based systems encounter and the several hierarchical blockchain-based solutions that scholars have suggested to address these problems.
