Digital Public Infrastructure refers to shared digital systems—typically built on open standards and governed as public goods—that enable identification, payments, and data exchange at population scale. Just as roads, electricity grids, and legal systems form the backbone of a physical economy, DPI provides the invisible rails on which digital economies run.
The concept gained global recognition through India's pioneering "India Stack," which demonstrated that emerging economies could leapfrog legacy systems by building interoperable digital layers from the ground up. Since then, the G20, the United Nations, and the World Bank have elevated DPI as a development priority, recognizing its capacity to accelerate financial inclusion, streamline public service delivery, and catalyse private-sector innovation.
Unlike traditional government IT procurement—often monolithic, proprietary, and slow to evolve—DPI follows a platform approach. Governments build thin, interoperable layers (identity verification, payment switching, consent-based data sharing) and allow markets to build applications on top. The result is an ecosystem where competition thrives, costs fall, and citizens retain choice.
