Abstract

Block-chain technology has evolved from its application in cryptocurrencies to become a widely accepted digital technology in various applications and fields. The major aspects of Blockchain technology are that they render trustworthy and reliability for applications without requiring intermediaries are their key properties of decentralization, immutable nature, cryptographic security mechanisms, and consensus mechanisms and transparency. The review paper majorly aims to study the applications of Blockchain technology in fields like, finance, healthcare, governance, digital forensic analysis, forensic analysis, and Internet of Things (IoT) applications. The review paper consolidates literature studies and provides an overview of various applications of blockchain technology to enhance security in financial transactions, to maintain the privacy and confidentiality of medical records in healthcare applications, and to maintain integrity and purity of evidence in forensic analysis while being free from custody, and complexity of blockchain technology that acts as a hindrance to its own applications and as well as for the applications of blockchain technology in IoT, requiring security and integrity of sources of information that remain untampered and unchanged for its applications and usage. Challenges in this area that the literature survey highlights include the scalability problem, energy issue, interoperability problem, regulatory hype, and no easy solution or process. The last section discusses the future work on how a scaled, privacy-conscious, and bespoke blockchain solution must be developed.
