Over the last several years, the IoT has made significant strides. In conventional IoT ecosystems, sensors feed data onto fog devices, which then upload the data to the Cloud. IoT is susceptible to threats to privacy and security because it lacks inherent security safeguards. With its “security by design,” Blockchain (BC) may assist in meeting the important security needs in IoT. Blockchain solutions may assist address most IoT architectural flaws by avoiding trusted third parties, protecting against a single point of failure, and avoiding trusted third parties altogether. To protect against possible attacks and lower transaction costs, distributed IoT systems may be built using the blockchain's capabilities, such as decentralization, consensus mechanisms, data encryption, and smart contracts. The performance of IoT security might be improved by using blockchain, a decentralized and open database platform. Researchers have been motivated by this to look at blockchain adoption in the IoT ecosystem. This study presents a survey on the integration of blockchain technology for security concerns with cloud, edge, and fog IoT systems. The goal of this study is to examine current research trends on the use of BC-related methodologies and tools in an IoT environment.
