India's Digital Public Infrastructure (DPI)
India's Digital Public Infrastructure forms the backbone of its AI ambitions. The India Stack -- comprising Aadhaar (biometric identity for 1.4 billion), UPI (Unified Payments Interface processing over 16 billion monthly transactions), DigiLocker, and Account Aggregator framework -- provides the digital rails upon which AI applications can be built at population scale. India's DPI model has attracted global attention, with the G20 New Delhi Leaders' Declaration (2023) recognising it as a template for inclusive digital transformation. The DPI approach follows an open, interoperable, and population-scale design philosophy.
- Aadhaar: 1.4 billion+ enrolments, world's largest biometric ID system
- UPI: 16+ billion monthly transactions valued at Rs 28+ lakh crore (January 2026)
- India Stack model endorsed by G20 New Delhi Declaration (2023) for global adoption
- ONDC (Open Network for Digital Commerce) extends the DPI model to e-commerce
- CoWIN platform demonstrated DPI's scalability during the vaccination drive (2.2 billion doses administered)
