Blockchain-Based Scalability Solutions for IoT: A Decentralized Design to Enhance Performance and Security

The Internet-of-Things facilitates the interlinking of an extensive number of devices, each capable of executing independent functions and acquiring diverse forms of information. These entities, in conjunction with the copious quantities of data they generate, necessitate scalable, proficient and safe-guarded management. Centralized solutions are not desired due to security concerns and scalability issue. Alternative to the centralized system, Blockchain – a decentralized systems that is proven to be platform to support both integrity and security is a choice. But, as the IoT devices are resource constrained devices, deploying a blockchain for the data management is a challenging task. In this manuscript, we put forth a multi-layer blockchain framework that accomplishes the goal of achieving scalability and access control in Internet of Things (IoT), gadgets including data. This framework is comprised of numerous permissioned blockchains that come together to configure a multi-layer architecture. As a result, it also attains high scalability using parallel processing, specifically through the utilization of blockchain sharding schemes.
