Block chain technologies have attracted a lot of attention from both the corporate sector and academia because to its decentralized, persistent, privacy, and auditability features. A survey is performed in this survey paper via a search for journal/research papers related to Block chain technology. To conduct this study, datasets were obtained from a variety of academic websites, including Science Direct, ACM Digital Library, and In der Science, to name a few. Following the first round of exclusion, 150 research papers were evaluated for the database survey's final round. The primary aim of this research is to provide academic academics with a comprehensive analysis of Block Chain technology and their many applications. The difficulties of implementing Block chain, as well as the security and privacy concerns that it raises, are also discussed. This study looked into the use of block chain technology in a variety of applications, as well as its implementation problems.
