Abstract

This article critically examines the dual role of blockchain and cryptocurrency technologies as both disruptive forces and pathways for sustainable integration into global financial markets. Through analysis of case studies and regulatory developments, the paper explores the tension between innovation and institutional adaptation. Key findings include case study evidence showing up to 30% cost reduction in blockchain-based remittance systems, juxtaposed with estimated annual global losses exceeding $3.5 billion due to cryptocurrency-related fraud and scams. The study evaluates institutional responses ranging from cautious experimentation to full adoption, and reviews global regulatory strategies, from progressive frameworks like the EU's MiCA to outright bans in certain jurisdictions. While the paper presents a broad synthesis of policy and market dynamics, it acknowledges the limitation of sparse empirical data and emphasizes the need for ongoing interdisciplinary research. Ultimately, the manuscript argues that hybrid approaches—such as private blockchain consortia and central bank digital currencies (CBDCs)—represent the most viable path forward, balancing innovation with financial stability and compliance.
