Economic Impact of Cryptocurrency Technologies in the Era of 4IR and 5IR: A Systematic Literature Review

The rapid development of cryptocurrency technologies now strongly affects worldwide economic change as nations implement the Fourth and Fifth Industrial Revolutions (4IR and 5IR). This review system investigates how blockchain technology and DeFi and smart contracts and digital identity systems interact with new governance approaches including regulatory sandboxes and innovation hubs. The 4IR focuses on digital automation and technological convergence yet the 5IR brings forward an ethical human-centered approach to innovation. The current governance systems face challenges because they operate independently from each other in different geopolitical areas while researchers study cryptocurrency regulation through different conceptual frameworks. The study uses PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for its Systematic Literature Review (SLR) to combine peer-reviewed articles from 2020 onwards for addressing these research gaps. The review examines 73 scholarly articles which were chosen through a multi-stage screening method in leading academic databases. The research uses thematic coding and semantic analysis to detect worldwide governance patterns and experimental regulatory approaches and ethical innovation indicators in 4IR and 5IR environments. The research investigates how cryptocurrency technologies transform economic systems into more inclusive systems which maintain adaptability and ethical principles. The research develops expandable governance systems which enable enduring digital transformation across multiple international environments.
