Abstract

Blockchain technology is an innovative economic development that is transforming corporate relationships. Distributed ledgers, safely shared and dispersed across network nodes, comprise its structure and hold detailed transaction records. As communication technologies progress at a rapid pace, the Internet of Things (IoT) is emerging from its early stages and into a fully developed state. Its rapid expansion is shown by the amount of data being processed and sent. A consensus method verifies every transaction that is logged in the network, guaranteeing that the data that is saved is unchangeable. Alongside the growth of the well-known digital currency Bitcoin, blockchain technology has gained popularity. Instead of depending on a single server or personal computer, cloud computing uses a network of distant servers housed on the internet to store, manage, and process data. In this regard, blockchain offers creative answers to problems with network security, data privacy, and decentralisation in cloud computing. Concurrently, Cloud of Things provides scalability and flexibility features to improve blockchain operations efficiency. A recently developed blockchain and cloud of things (BoCoT) combination is well known for being a powerful facilitator for a broad variety of application scenarios. This article provides readers with an in-depth examination of the most recent state-of-the-art blockchain integration, covering a range of topics such as history, driving forces, and integrated design. The goal is to provide a comprehensive overview of blockchain’s capabilities and how it integrates into different fields.
