A Review of Blockchain Technology in Smart Applications: Research Issues and Open Challenges

The increasing urbanization of the worldwide people has a significant impact on societal attitudes, particularly life expectancy, as a consequence of a variety of macroeconomic, sociological, and environmental changes. The idea of a “smart city” creates opportunities for addressing important urban problems. Smart cities strive to provide exceptional services to the populace, more efficiently use public funds, and advance general welfare. Technology tools are essential to the development of ubiquitous computing. Trustlessness, traceability, anonymity, democracy, automation, decentralization, and confidentiality are just a few advantages of blockchain technology.The development of IoT technology and the upgrading of intelligent devices are both facilitated by these cryptocurrency capabilities. In this post, we will provide a thorough assessment of published literature on decentralized blockchain systems in wide variety of applications. We start with talking about the core ideas behind distributed ledger technology before moving on to the various fields it has been used in, like the Internet of Things, agribusiness, financial, as well as other businesses. Finally, we examined several security issues facing the healthcare sector and thoroughly examined blockchain technology’s trustworthiness.
