Blockchain - Integrated Digital Payment Systems in the Public Sector: Innovation, Transparency, and Economic Efficiency in Emerging Markets

Abstract

The ability of blockchain technology to innovate digital payments system is increasingly recognized, particularly in the public sector of emerging economies. This paper takes an exploratory approach to find out how it can be possible for blockchain-integrated digital payment systems to create enhanced transparency and security alongside improved economic efficiency in public finance by developing India's Unified Payments Interface as a model for scalable, government-supported digital payment frameworks. In an emerging market, blockchain immutability and decentralization potentially minimize corruption and reduce transaction costs, enhancing ease of cross-border payments, which are believed to spur inclusive economic growth. This study builds on a comprehensive review of previous literature and an analysis of the application of blockchain in public finance to examine the potential of blockchain to foster transparency and trust, overcome technological and regulatory challenges, and improve efficiency in financial transactions. In addition, a UPI case study is performed to describe the blockchain pros and cons in mature digital payment infrastructures. Based on this analysis, practical policy recommendations are derived for governments, central banks, and other stakeholders who are interested in blockchain adoption for sustainable, secure, and transparent digital finance ecosystems. This paper endeavours to explain the comprehensive framework to understand the value of blockchain in public sector payment systems by providing some insights into the opportunities that can be pursued and practical steps that need to be taken in order to fully leverage blockchain in the digital payment landscape of emerging economies.
