The G20 Digital Economy Working Group and New Delhi declaration have drawn significant attention to the concept of Digital Public Infrastructure (DPI) and made it a critical topic of discussion in international fora. Here at University College London’s Institute for Innovation and Public Purpose (IIPP), David Eaves and Jordan Sandman defined DPI as a set of digital capabilities that are essential for participation in modern society. Prominent examples of DPI include the Central Bank of Brazil’s Pix (instant payments), India’s Aadhaar (digital ID), and the Estonia-led X-Road (data exchange layer). Others, such as the UNDP, have adopted similar or even broader definitions, often grounded in Brett Frischmann’s view of infrastructure as a “shared means to many ends.”
