Definition
Digital Public Infrastructure refers to a set of open, interoperable and scalable digital systems that enable governments, citizens and businesses to deliver and access services efficiently. It functions like physical infrastructure such as roads or electricity, but in the digital domain.
Core Architecture of DPI
DPI generally operates through three foundational layers supported by interoperable platforms.
A. Digital Identity Layer
• Unique and secure identity authentication
• Enables e-KYC and service access
• Reduces duplication and leakages
Example: Aadhaar
B. Digital Payments Layer
• Real-time, low-cost and interoperable payment rails
• Enables instant fund transfers
• Supports DBT and financial inclusion
Example: UPI
C. Data Exchange Layer
• Consent-based and secure data sharing
• User-controlled access to financial and personal data
• Enables credit access and digital services
Example: Account Aggregator Framework
D. Supporting Platforms
• Digital document vaults – DigiLocker
• Unified service access – UMANG
• Public procurement – GeM
• Health platforms – CoWIN, eSanjeevani
• Open APIs – India Stack, API Setu
Evolution of DPI in India
Phase 1: Siloed E-Governance (Pre-2010)
• Department-specific portals
• Limited interoperability
• Fragmented service delivery
Phase 2: Foundational Platforms (2010–2015)
• Launch of Aadhaar
• India Stack architecture
• API-driven governance
Phase 3: Ecosystem Expansion (2015–2025)
• UPI for payments
• DigiLocker for document digitisation
• CoWIN for vaccination management
• Account Aggregator for data empowerment
• Integration across sectors
