Digital Public Infrastructure | Chatham House 2025 Report

What Is Digital Public Infrastructure and Why It Matters Now

Digital public infrastructure (DPI) represents a fundamental shift in how governments approach technology — moving from fragmented, vendor-dependent IT projects to society-scale digital systems built on interoperability, openness, and secure data sharing. The October 2025 Chatham House report by Rowan Wilkinson, Alex Krasodomski, and Isabella Wilkinson presents DPI as both a set of design principles and the digital platforms that emerge from them, including digital identity systems, payment networks, and data exchange frameworks.

The report arrives at a critical juncture. As the global order fractures along technological lines — with US-China competition intensifying, the second Trump administration reshaping tech policy, and the Russia-Ukraine war demonstrating the strategic value of digital resilience — nations face unprecedented pressure to secure sovereignty over their critical digital systems. DPI offers a tested, scalable, and remarkably cost-effective alternative to the traditional approach that has left governments locked into expensive contracts with foreign providers.

Currently informing the digitalization strategies of approximately 60 nations, DPI was formally recognized by the United Nations and the G20 in 2023. This recognition signals a fundamental reframing of the digital state — not as a passive consumer of commercial technology, but as a platform for innovation and sovereignty. For organizations seeking to understand how digital transformation reshapes institutional practice, the Chatham House analysis provides an indispensable framework.

The Failure of Traditional Government Digitalization

Before understanding why DPI matters, the Chatham House report meticulously documents how traditional approaches to government digitalization have consistently fallen short. Past efforts have been characterized by astronomical costs, long-term dependence on foreign service providers, siloed projects resulting in duplication and waste, vendor lock-in, and inflexibility that leaves systems unable to adapt to new challenges.

The numbers are stark. Government IT spending in OECD countries runs approximately 20 times higher than in non-OECD nations, averaging roughly $250 per capita in advanced economies compared to just $14 per capita elsewhere. Closing this gap would require nearly $1.4 trillion in new annual spending — a figure that underscores how the traditional model simply cannot scale to serve the developing world.

Failed mega-projects illustrate the human cost. The UK’s National Health Service digitalization attempt collapsed in 2011, described as one of the “worst and most expensive contracting fiascos” in public sector history. During the COVID-19 pandemic, the United States lost an estimated $280 billion to relief fraud — a failure the report attributes in part to state unemployment systems running on technology nearly 50 years old. These failures are not aberrations; they are the predictable outcomes of a procurement model that prioritizes commercial relationships over institutional resilience and digital innovation.

Digital Identity Systems Transforming Government Services

Digital identity represents the foundational layer of DPI, and the Chatham House report provides compelling evidence of its transformative impact. India’s Aadhaar system, the world’s largest biometric identity program with over 1.4 billion enrollments, reduced the cost of identity verification from $10–$12 per transaction to approximately $0.20 — a 98% cost reduction that has enabled an explosion of digital services.

The impact extends well beyond cost savings. Indian adults with bank accounts more than doubled between 2011 and 2021, driven largely by the ability to verify identity digitally during account opening. Singapore’s Singpass system provides citizens access to over 2,700 services across 800 government agencies and private businesses, creating a seamless digital identity layer that spans the public and private sectors.

Open-source approaches are making sovereign digital identity accessible to developing nations. MOSIP (Modular Open Source Identity Platform), launched with just $28 million in philanthropic funding and operating on an annual budget of $5–7 million, has already engaged over 25 countries. This demonstrates that building foundational digital infrastructure no longer requires the massive budgets associated with proprietary solutions — a lesson with profound implications for the roughly 850 million people worldwide who still lack any form of official identity.

The United Kingdom announced mandatory digital identity verification in September 2025, but the Chatham House authors argue that success depends on extending digital ID far beyond right-to-work checks into healthcare, taxation, and cross-departmental service delivery. They specifically recommend that the UK adopt India’s Data Empowerment and Protection Architecture as a model for managing citizen consent over personal data use.

Digital Payment Platforms Driving Financial Inclusion

Digital payment systems represent perhaps the most immediately visible DPI success story. Brazil’s Pix platform, launched by the central bank, now serves 153 million users with average merchant transaction costs of just 0.22% — compared to credit card fees of 2.2%. This tenfold reduction in transaction costs has transformed the economics of small business commerce and dramatically expanded financial access for underserved populations.

India’s Unified Payments Interface (UPI) serves over 500 million users, enabling instant mobile payments across the entire financial system. Kenya’s M-PESA mobile money platform has become so deeply embedded in the economy that 59% of Kenya’s GDP now flows through it — contributing to a measurable 3.4% increase in per capita real income between 2006 and 2013. The system’s success also created new fiscal opportunities: Kenya imposed a 3% duty on M-PESA transactions in 2024, demonstrating how digital payment infrastructure can expand the tax base.

The crisis resilience benefits are equally significant. Countries with pre-existing DPI reached three times more beneficiaries with emergency cash transfers during COVID-19. Togo’s NOVISSI program used mobile payment infrastructure to deliver targeted relief to vulnerable populations rapidly, while Bangladesh distributed anticipatory mobile transfers of $37 per person ahead of forecasted floods — a model of proactive disaster response enabled entirely by digital payment rails.

Data Exchange Frameworks and Interoperability

The third pillar of DPI — data exchange systems — addresses the chronic problem of government data silos. Estonia’s X-Road platform, the gold standard in this category, facilitates over 3,000 public and private services through a secure, decentralized data exchange layer. Now deployed in over 100 countries, X-Road demonstrates that interoperability at national scale is both technically feasible and economically advantageous.

The efficiency gains are remarkable. Estonia claims its DPI ecosystem saves over 1,400 years of cumulative working time annually, contributing to estimated GDP savings of 2%. Denmark’s Digital Post system — a cross-government digital postal service — saves €270 million annually by eliminating paper-based correspondence. South Korea’s Busan smart city project projects savings of 124 hours per year per resident, spanning 60 hours in commuting, 20 hours in administrative tasks, and 5 hours in hospital waiting times.

International trade presents another compelling use case. Singapore’s TradeTrust platform reduced bill of lading processing from 5–10 days to under 24 hours by digitizing and standardizing trade documentation. The EU Digital COVID Certificate, adopted by all 27 member states, demonstrated that cross-border data verification can be implemented rapidly when built on interoperable standards — a proof of concept now being extended to other health credentials through the WHO’s Global Digital Health Certification Network.

Peru’s PIDE platform and Sri Lanka’s emerging DPI stack further illustrate how data exchange frameworks can be adapted to diverse institutional contexts. The key insight from Chatham House is that interoperability is not merely a technical requirement but a governance principle — it ensures that digital systems serve citizens rather than the commercial interests of the vendors who build them.

Digital Sovereignty in a Geopolitically Fractured World

The Chatham House report places DPI squarely within the geopolitical context of 2025, arguing that digital sovereignty has become a strategic imperative rather than a technical preference. French President Macron’s declaration that Europe “cannot depend on a few American companies to manage our data infrastructure” captures the urgency: critical digital systems controlled by foreign entities represent a vulnerability that nations can no longer afford.

The evidence supports this concern. The July 2024 CrowdStrike outage caused an estimated $10 billion in damages within hours, exposing how deeply governments and businesses depend on a handful of technology providers. US Senator Ron Wyden warned that “the government’s dependence on Microsoft poses a serious national security threat.” Ukraine’s wartime experience, while demonstrating the value of digital platforms like Diia for maintaining government services, also revealed dangerous dependencies on US cloud providers for critical national data.

Estonia’s innovative “data embassy” concept — a data center in Luxembourg operating under Estonian jurisdiction, inspired by the Vienna Convention on Diplomatic Relations — represents one creative solution to sovereignty challenges. The EU’s proposed EuroStack initiative and GAIA-X cloud project aim to create European alternatives to American cloud dominance, though the report acknowledges that these efforts face significant headwinds given the entrenched position of AWS, Azure, and Google Cloud.

For developing nations, the sovereignty stakes are equally high. The report warns of a binary choice emerging between US and Chinese technology ecosystems, with Pakistan’s exposure through the China-Pakistan Economic Corridor digital systems cited as a cautionary example. Open-source DPI offers a third path — one that enables nations to build sovereign digital capabilities without aligning exclusively with either technology superpower.

DPI for Crisis Resilience and National Security

The report makes a compelling case that DPI strengthens national resilience in ways that go far beyond routine service delivery. Ukraine’s Diia platform — which maintained critical government services including tax filing, war bond purchases, troop movement reporting, and e-restoration programs throughout active military conflict — stands as the most dramatic example of DPI’s value during crisis.

COVID-19 provided a global stress test. Countries with pre-existing digital public infrastructure reached three times more beneficiaries with emergency cash transfers than those without. The contrast with the United States, where an estimated $280 billion in relief funding was lost to fraud due to outdated systems, illustrates the cost of delayed DPI investment. Bangladesh’s ability to deliver anticipatory flood relief payments of $37 per person via mobile infrastructure demonstrated how DPI enables proactive rather than reactive disaster response.

The security dimension extends to critical infrastructure protection. The CrowdStrike outage demonstrated that concentration risk in commercial technology creates systemic vulnerabilities. DPI’s emphasis on open-source components, interoperability, and distributed architecture reduces single points of failure. Estonia’s data embassy ensures government continuity even if the country’s physical territory were compromised — a consideration that resonates far beyond the Baltic states in an era of hybrid warfare.

Risks, Governance, and Democratic Safeguards for Digital Infrastructure

The Chatham House authors are candid about the risks accompanying DPI expansion. Centralized digital identity systems can enable surveillance and authoritarian abuse — China’s Social Credit System represents the dystopian endpoint. Digital payment systems are inherently more monitorable than cash transactions, raising profiling and social scoring concerns. Biometric data collected for identity verification can be repurposed for controversial applications, including automated facial recognition in law enforcement.

The report identifies several categories of risk requiring active governance. Privacy and data protection demand robust legal frameworks, with India’s Data Empowerment and Protection Architecture cited as a model for managing citizen consent. The digital divide threatens to exclude populations without reliable internet access or digital literacy, potentially worsening existing inequalities. Vendor capture — where commercial software “masquerades as DPI” while maintaining proprietary lock-in — represents a subtler but equally dangerous threat, as illustrated by concerns over the UK’s NHS Federated Data Platform.

Governance recommendations emphasize transparency, democratic oversight, and accountability mechanisms. The authors call for privacy-enhancing technologies, clear avenues for public redress, and governance structures modeled on successful international organizations like Gavi (the global vaccine alliance). The encryption debates — highlighted by UK legal battles with Apple and WhatsApp — demonstrate that regulation alone cannot guarantee sovereignty; technical architecture must be designed from the outset to protect civil liberties.

Policy Roadmap for Digital Public Infrastructure Adoption Worldwide

Chatham House distills its analysis into four core recommendations for governments seeking to adopt DPI approaches. First, establish a clear political and institutional mandate by recognizing digital infrastructure as a strategic national asset. This requires creating dedicated institutional mechanisms — whether mandated government departments (as with the UK’s Department for Science, Innovation and Technology), US-style public-private taskforces, or digital architecture boards with statutory powers.

Second, grow technical capacity aggressively. Governments must develop institutions capable of designing, procuring, operating, and regulating critical technologies. This means reforming workplace culture, investing in human capital, and using strategic immigration policy to attract and retain technical talent. The UK’s Advanced Research and Invention Agency (ARIA) and Government Digital Service (GDS) are cited as models worth emulating, alongside the concept of “focused research organizations” modeled on the Large Hadron Collider or Human Genome Project.

Third, identify high-impact use cases through rigorous cost-benefit analysis rather than pursuing digitalization for its own sake. This requires coordination among budget holders, digital regulators, and sector-specific agencies. The report emphasizes that successful DPI implementations in one context can often be replicated where conditions are similar — making the case for international knowledge sharing rather than building everything from scratch. For institutions exploring how digital tools can transform organizational knowledge management, this use-case-driven approach offers a practical model.

Fourth, plug into global DPI networks. No nation — not even technology superpowers — can achieve full digital self-sufficiency. Participation in initiatives like the UN Global Digital Compact, the 50-in-5 program (aiming to deploy DPI in 50 countries within five years), and the Digital Public Goods Alliance enables countries to leverage shared resources, set international standards, and avoid redundant investment.

Global DPI Networks and the Path Forward

The final sections of the Chatham House report look ahead to the emerging global architecture for DPI cooperation. The 50-in-5 initiative represents the most ambitious multilateral effort, aiming to deploy foundational DPI components — identity, payments, and data exchange — in 50 countries by 2028. The Digital Public Goods Alliance maintains a registry of open-source tools that meet international standards, though the authors note that gaps remain and funding for open-source DPI is insufficient.

The report frames DPI as a diplomatic instrument as well as a technical one. The authors argue that “had China, rather than the US, been the driving force behind the internet, the core principles of freedom of expression, open access and user privacy that today shape many digital societies might have looked rather different.” This observation underscores the stakes: the design principles embedded in foundational digital infrastructure shape the societies built upon them for generations.

For the European Union, the path involves consolidating fragmented initiatives — eIDAS for digital identity, GAIA-X for cloud sovereignty, the EU Digital COVID Certificate framework for cross-border verification — into a coherent DPI strategy. The estimated cost of extending Estonia’s X-Road across the EU was just €252,000 per country, with EU cohesion funding potentially covering up to €352,000 — a remarkably modest investment relative to the billions spent on proprietary alternatives.

The report concludes that DPI is “more than a technical solution: it is a new theory of change that reframes the digital state as a platform for innovation and sovereignty.” For governments, international organizations, and private sector leaders navigating an increasingly fragmented digital landscape, the Chatham House analysis provides both the evidence base and the policy roadmap for a fundamentally different approach to digital transformation — one that prioritizes public interest, interoperability, and democratic values over commercial convenience.
