How does the ABDM's registry architecture reflect India's broader 'digital public infrastructure' approach seen in Aadhaar and UPI?

Q. How does the ABDM's registry architecture reflect India's broader 'digital public infrastructure' approach seen in Aadhaar and UPI? (15 marks, 250-350 words)

Digital Public Infrastructure (DPI) refers to minimal, open and interoperable digital building blocks provided as public goods, on which both state and market actors build services — the template set by Aadhaar in identity and UPI in payments. The Ayushman Bharat Digital Mission (ABDM), launched in 2021 under the National Health Authority (NHA), applies precisely this template to health by making verified registries, not a single government app, its core.

A trusted identity layer — the Aadhaar analogy - ABHA, a 14-digit health account, works as health's identity spine, stitching records scattered across providers into one longitudinal record [1]. - Adoption is population-scale, as with Aadhaar: over 90 crore ABHAs created and over 100 crore health records linked [2][3]. - HFR and HPR extend this to institutions and providers — verified directories of health facilities and professionals (3.63 lakh and 5.64 lakh respectively as of February 2025), supplying the trust that any transaction layer needs [1].

Unbundled, interoperable rails — the UPI analogy - Just as UPI separates payment rails from consumer apps, ABDM's Health Information Exchange & Consent Manager, Unified Health Interface and National Health Claims Exchange let any standards-compliant application discover facilities and exchange data [4]. - Over 450 public and private health-tech solutions have integrated with the ecosystem — private innovation riding on public rails [2]. - The design is federated and minimalist: records stay with providers, only pointers and consent artefacts move; NHA sets standards while states onboard entities [1].

Institutional and governance parallels - A dedicated custodian (NHA, mirroring UIDAI/NPCI) with a Cabinet outlay of Rs. 1,600 crore over five years [5]. - Explicit consent-based sharing, read with the DPDP Act, 2023 — engaging the same privacy questions Aadhaar raised.

ABDM thus demonstrates that DPI is a replicable governance method rather than a one-off innovation: identity, registry and interoperability layers built once and reused widely. Sustaining it will require closing rural digital-divide and last-mile onboarding gaps, so that these registries translate into genuine Universal Health Coverage.
