Cryptocurrency in the Digital Economy: A Critical Analysis of Technological Foundations, Evolutionary Trends, and Macroeconomic Implications

Abstract

Cryptocurrency has transitioned from a cryptographic curiosity to a transformative force in the global economy. Rooted in blockchain technology, it has catalysed financial innovation, disrupted traditional monetary systems, and spurred new economic paradigms like decentralized finance (DeFi). This paper explores the fundamentals of crypto currency, critically evaluates its technological underpinnings, and traces its evolution over time. Furthermore, it examines the macroeconomic implications of large-scale adoption, including monetary policy challenges, regulatory dilemmas, and the shifting structure of global finance. Through a multidisciplinary lens combining technology, economics, and policy analysis, this paper contributes to a deeper understanding of crypto currency's complex role in shaping the digital economy.
