THE CURRENT REVIEW OF BLOCKCHAIN TECHNOLOGY AND ITSSUSTAINABILITY

Abstract

 The blockchain is a distributed technology for handling information and transactions that was initially created for the Bitcoin cryptocurrency. Since the notion of blockchain technology was first proposed in 2008, interest in it has grown. Blockchain is gaining popularity because of its primary advantages, which include security, anonymity, and data trustworthiness without requiring a third party to manage transactions. As a result, it opens up new research areas, particularly when considering technical difficulties and constraints. To compile all pertinent studies on blockchain technology, we carried out a methodical mapping investigation in this study. Our goal is to comprehend, from a technical standpoint, the current research subjects, issues, and future directions related to blockchain technology.41 original publications from our scientific databases. The findings indicate that more than 80% of the articles concentrate on the Bitcoin system, with fewer than 20% covering other blockchain uses, such as smart contracts and licensing. Most of the related research has focused on identifying and addressing the privacy and security flaws of blockchain technology, although the efficacy of many of the suggested fixes has not been well tested. Numerous other issues pertaining to the sustainability of blockchain technology as a whole, such as throughput and latency, remain unexplored. Researchers are given suggestions for future research directions based on the outcomes of this study.
