Block chain and Its Current Applications: A Critical Analysis

Abstract

 Blockchain has the potential to address these key issues. Bitcoin, along with blockchain, was created as the first and most widely used cryptocurrency. Since the advent of Bitcoin, the first and biggest cryptocurrency, block chain technology has been recognized as a digital currency platform. It has previously been used for decentralization of markets in general, rather than just decentralization of money and payments. The block chain's decentralized transaction ledger may be used to register, confirm, and transmit various types of contracts to other network participants. We fully examine state-of-the-art block chain-related applications that have appeared in the literature in this article. A number of previously published publications were carefully considered for inclusion based on their contributions to the block chain body of knowledge. In the last part of the article, many points are examined and debated.
