[Challenges and responses]
⚠️ Energy Consumption Matters: RBI Asks All Node Operators to Transition to Green Data Centres by 2025
⚠️ DIGITAL DIVIDE: Telecom Ministry launches Rs 1 billion special fund to develop voice-driven blockchain interface

This cycle of change is creating an incremental market space of about $12 billion per annum. With the deeper integration of the Aadhaar system with the CBDC, it is expected that India could be the first major economy to achieve a "full-stack digital financial infrastructure" by 2026.
