Digital Public Infrastructure and the Future of Inclusive State Capacity

For much of India’s post-independence history, governance reform meant expanding institutions. New departments, new schemes, and new administrative layers were created to solve development problems. The result was often a dense architecture of welfare programmes that struggled with coordination, identification of beneficiaries, and delivery inefficiencies. Over the past decade, however, India has begun experimenting with something different. Instead of building new bureaucratic layers for every policy objective, the state has started constructing digital systems that multiple programmes can use simultaneously. These systems, commonly described as Digital Public Infrastructure (DPI), are gradually reshaping how governance itself is organised.

At its core, DPI rests on a simple idea: the state provides open, interoperable digital rails that both public services and private innovation can run on. Rather than delivering each service through a stand-alone administrative apparatus, governments rely on shared digital platforms that standardise identity verification, payments, documentation, and data exchange.

Three foundational layers have come to define India’s DPI architecture.

These platforms were not built simultaneously. They emerged gradually through policy experimentation between 2009 and the mid-2020s. Yet together they now form an integrated ecosystem that increasingly underpins welfare transfers, financial services, digital commerce, and even administrative documentation. The most visible component of this architecture is the Unified Payments Interface (UPI). Launched in 2016 by the National Payments Corporation of India, UPI created a public digital payments infrastructure that any bank or fintech firm could plug into. Instead of competing proprietary payment networks, India adopted a shared system where private companies build user-facing applications while transactions are settled on a common infrastructure. The scale this system has reached in less than a decade is remarkable.

UPI now accounts for the vast majority of India’s digital payments ecosystem, with around 85% of all digital transactions flowing through the platform.

Monthly volumes frequently exceed 20 billion transactions, with daily averages approaching 700 million payments processed across banks and payment apps.  These numbers are not simply evidence of technological success. They illustrate a deeper institutional shift. For decades, financial inclusion was pursued primarily through expanding bank branches or subsidising accounts. DPI approached the same problem differently, by lowering the cost of transactions and allowing digital payments to become routine even for small-value purchases. Street vendors, small retailers, and informal workers increasingly use QR-code payments as part of everyday commerce. In many small towns, the question is no longer whether digital payments will replace cash, but how quickly the transition will happen. The same logic is visible in welfare delivery. Earlier, social protection programmes relied on elaborate bureaucratic chains to identify beneficiaries and transfer benefits. Leakages, delays and duplication were persistent challenges. By linking Aadhaar identification with bank accounts and mobile connectivity, often referred to as the JAM architecture (Jan Dhan–Aadhaar–Mobile), welfare transfers increasingly move directly from the treasury to citizens.

These outcomes suggest that DPI is not merely about digitisation. It changes the administrative logic of welfare itself. Once digital identity and payment rails are laid out, new schemes can be implemented far more rapidly because the underlying infrastructure is already in place. The COVID-19 pandemic offered a revealing demonstration of this capacity. India’s CoWIN platform coordinated vaccination scheduling, verification, and digital certification at a national scale. Irrespective of the political debates surrounding pandemic management, the digital platform showed how governance could be organised through interoperable technological systems rather than purely through administrative hierarchies. Yet the governance implications of DPI extend beyond welfare delivery.

One of the more interesting features of the Indian model is that the state builds infrastructure but does not monopolise services built on top of it. UPI is a good example. Google Pay, PhonePe, Paytm and numerous other apps compete for users, but all operate on the same payments backbone. This approach preserves competition while preventing the infrastructure itself from being captured by a single private platform. The model resembles public infrastructure in the physical world. Highways are built by the state but used by private vehicles and logistics firms. Similarly, digital public infrastructure provides the rails upon which private innovation can operate. This approach has attracted growing international attention. Countries across Asia, Africa and Latin America are now studying the Indian model as a way to expand financial inclusion without relying entirely on expensive banking networks.

However, treating DPI purely as a technological success story would overlook the challenges that accompany it. The first concern is exclusion. Digital governance assumes reliable connectivity, functioning authentication systems and a certain degree of digital literacy. When these conditions fail, individuals can find themselves temporarily locked out of services. Biometric authentication failures, patchy network connectivity in rural areas, and limited familiarity with digital interfaces remain real constraints. Second, data governance is becoming an increasingly sensitive issue. DPI platforms generate enormous volumes of personal and financial data. The question of how this data is stored, accessed and regulated will determine public trust in the system. India’s evolving data protection framework is an attempt to address these concerns, but institutional capacity in this domain is still developing. Third, there are emerging concerns about concentration within the ecosystem itself. Even though UPI is an open infrastructure, a high percentage of transactions flows through a small number of private applications. Regulators have already explored mechanisms such as transaction caps to prevent excessive concentration within the payments ecosystem. These debates are inevitable in any infrastructure transition. Railways once raised concerns about monopolies and regulation. Telecommunications required decades of regulatory refinement. Digital infrastructure will likely follow a similar trajectory.

Despite these challenges, the broader significance of DPI lies in the institutional imagination it represents. For decades, the dominant debate in development policy revolved around the relative roles of the state and the market. Should governments deliver services directly, or should markets take over? Digital public infrastructure suggests a third possibility: the state as a builder of foundational platforms that enable both welfare delivery and market participation. The implications of this approach extend beyond payments and welfare. New initiatives such as the Open Network for Digital Commerce (ONDC) are attempting to apply the same logic to e-commerce by creating interoperable digital marketplaces that reduce platform monopolies. Similar efforts are emerging in areas like health records, education credentials and data-sharing frameworks.

If these systems succeed, governance in the digital age may increasingly operate through infrastructure rather than programmes. In other words, the real transformation underway in India is not simply the digitisation of government services. It is the emergence of a new administrative philosophy: build shared digital rails first, and allow both public policy and private innovation to move across them. Thus Digital public infrastructure is not just a technological achievement. It represents a new way of organising the relationship between the state, markets and citizens; one that could redefine governance in the twenty-first century.
