Over the past decade, the term Digital Public Infrastructure (DPI) has moved from a policy buzzword to a national priority. Countries are realizing that foundational systems like digital identity, payment rails, and trusted data exchange are as critical as roads, power grids, or water supply.
We have seen remarkable progress: India’s Aadhaar and UPI, the EU’s work on the EUDI Wallet, Smart Africa’s blueprint, and national ID systems across Asia, Africa, and Latin America. These initiatives prove the potential of DPI to drive inclusion, efficiency, and growth.
But some of these implementation offer a crucial lesson: centralized models of DPI are not sustainable for the future.
Security Risks
A central database is a prime target for cyberattacks. A single breach can compromise millions of citizens’ data.
High Costs
Building and maintaining centralized infrastructure demands continuous investment in servers, connectivity, and data centers.
Limited Reach
Citizens must often travel to fixed service points. Rural, offline, or underserved communities remain excluded.
Innovation Bottleneck
With government owning and running everything, the private sector’s role is limited to integration—not co-creation.
No more single points of failure. In a decentralized architecture, identity credentials, payment tokens, and health records are distributed across citizen-controlled wallets and institutional nodes. If one system goes down, the ecosystem continues.
2. Lower Total Cost of Ownership (TCO):
Instead of maintaining massive centralized infrastructure, governments can leverage existing citizen devices(smartphones), financial institutions, and telcos. This shifts costs from taxpayers to a shared ecosystem model while reducing government overhead.
3. Inclusion at Scale: With decentralized wallets, verifiable credentials, and offline capabilities, the system goes to the citizen—not the other way around. Rural farmers, urban workers, refugees, and migrants all gain access without depending on centralized service points.
4. Privacy and Trust: Citizens can share only what’s needed, when it’s needed. Technologies like selective disclosure and zero-knowledge proofs allow verification without revealing sensitive personal data. This restores trust between government and citizens at a time when data misuse is a growing concern. Trust is bilateral, while services providers can assert they are serving the right citizen, the citizen can also trust the service provider is legitimate and operating within approved guard rails.
5. Ecosystem-Led Growth: Governments don’t need to build every app or service. By establishing a trust framework and open standards, they enable banks, fintechs, healthcare providers, and innovators to build on top. The result? A thriving digital economy that extends well beyond government services.
