DHRUVA framework
Why in News?
May 2025: Department of Posts proposed DHRUVA (Digital Hub for Reference and Unique Virtual Address).
Government released:
Draft amendment to the Post Office Act, 2023 to legally enable DHRUVA.
Follows the launch of DIGIPIN (geo-coded location pin system).
Policy concerns raised by:
Dvara Research on privacy, consent, and urban governance limitations.
Relevance
GS 2 – Governance
E-governance, Digital Public Infrastructure
Consent-based data sharing and privacy
Urban governance and service delivery
Legal gaps in data regulation
GS 3 – Infrastructure & Digital Economy
Logistics efficiency
Platform economy
Last-mile service delivery
Smart cities and geospatial governance
What is DHRUVA?
DHRUVA = a proposed Digital Public Infrastructure (DPI) for standardised digital addresses.
It converts physical addresses into virtual “labels”, similar to:
Email IDs
UPI IDs
Example:
Instead of writing a long address → user shares something like amit@dhruva.
Core Objective of DHRUVA
Standardisation of addresses across platforms
Consent-based sharing of address data
Service discovery:
Identifying what doorstep services are available at a user’s location
Improve:
Governance
Logistics
E-commerce delivery
Emergency services
What is DIGIPIN?
Developed in-house by India Post.
10-digit alphanumeric, geo-coded digital pin
Coverage:
Every 12 square metre block in India
Use-case:
Rural areas with weak descriptive addressing
Precise fallback for:
Postal delivery
Emergency response
How Will DHRUVA Work?
DHRUVA ecosystem includes:
Address Service Providers (ASPs)
Generate proxy address labels
Address Validation Agencies (AVAs)
Authenticate address authenticity
Address Information Agents (AIAs)
Handle user consent management
Central Governance Entity
On the lines of National Payments Corporation of India (NPCI)
How Will DHRUVA Be Used?
(A) Consent-Based Address Sharing
Users tokenise addresses, like:
UPI tokenises bank accounts
User controls:
Who can access
For how long
For what purpose
(B) Seamless Address Updating
When a person shifts residence:
All linked platforms automatically update delivery location.
(C) Logistics & Platform Integration
Supported platforms:
Amazon
Uber
India Post
Gig economy & food delivery platforms
Why is DHRUVA Being Framed as DPI?
DHRUVA is aligned with India’s DPI model like:
Aadhaar → Identity
UPI → Payments
DigiLocker → Documents
DHRUVA → Addresses
Features:
Public ownership
Interoperable
Platform-neutral
Consent-based data flows
Will It Help Urban Governance?
(A) Key Concern Highlighted by Dvara Research
Addresses in DHRUVA are linked to people, not independently mapped physical structures.
Implication:
Urban planning requires structure-based data, not merely person-based data.
(B) Consent Paradox
Since personal data is collected:
User consent becomes mandatory.
If citizens refuse consent:
Datasets become incomplete
Result:
Weak urban planning
Faulty population projections
Inaccurate infrastructure mapping
(C) Global Best Practice Contrast
In most advanced economies:
Digital addresses are linked to surveyed buildings
Not tied to personal identity
This:
Eliminates consent dependency
Enables richer governance datasets
Governance & Legal Challenges
No standalone law yet authorising large-scale address data collection
Dvara recommendation:
Dedicated draft legislation required
Key risks:
Surveillance through address linkage
Profiling via location-based service history
Function creep across welfare, policing, taxation
Benefits of DHRUVA (If Designed Safely)
Faster emergency response
Seamless service discovery
Reduced address fraud
Lower logistics costs
Inclusion of rural habitations without formal addresses
Key Risks
Privacy erosion
State surveillance potential
Market monopolisation by large platforms
Weak anonymisation of geospatial data
Exclusion if digital consent infrastructure fails
Strategic Bottom Line
DHRUVA represents:
Next frontier of India’s DPI stack
Digital control layer for geography + service delivery
However:
Without clear legal backing, anonymised structure-mapping, and privacy-by-design:
It risks becoming a surveillance-grade address infrastructure
Success hinges on:
Independent structure mapping
Firewalls between identity and location
Strong statutory oversight
Crypto transactions crossed ₹51,000 cr. in 2024-25 in India’
Why in News?
2024–25: Crypto transaction value in India crossed ₹51,000 crore, registering 41% year-on-year growth.

What is Cryptocurrency?
Cryptocurrency = a digital asset based on:
Blockchain technology
Cryptographic security
Decentralised ledger system
In Indian law, crypto is classified as:
Virtual Digital Asset (VDA)
Not legal tender
Treated as a taxable asset, not currency
What are Virtual Digital Assets (VDAs)?
Defined under the Income Tax Act as:
Cryptocurrencies (Bitcoin, Ether)
Non-Fungible Tokens (NFTs)
Other cryptographic tokens
Excludes:
Indian digital rupee (e₹) issued by RBI
How is Crypto Taxed in India?
Legal Basis
Introduced under the Finance Act, 2022
Continued under the Income Tax Act, 1961 (retained in I-T Act 2025 framework)
Tax Structure
30% flat tax on profits from VDAs
No loss set-off allowed
1% TDS on every transaction
Deducted at the time of transfer
Applies irrespective of profit or loss
How Was ₹51,180 Crore Estimated?
Government collected ₹511.8 crore as 1% TDS
Since:
1% TDS = Total Transaction Value × 0.01
Therefore:
Total crypto transaction value
= ₹511.8 crore × 100
= ₹51,180 crore
What Does the Growth Indicate?
Mass retail participation despite:
High volatility
Strict taxation
Indicates:
Rising financialisation among youth
Shift towards alternative assets
Platform-driven crypto trading boom
Why Is Crypto Growing Despite Heavy Taxation?
Frictions like:
30% flat tax
1% TDS per transaction
Yet growth due to:
Bull cycles in global crypto markets
Ease of app-based crypto trading
Narrative of crypto as:
Inflation hedge
High-risk, high-return instrument
Economic Implications for India
(A) Revenue Mobilisation
Stable non-traditional tax base
Predictable TDS inflows
(B) Capital Flight Risk
Unregulated cross-border transfers
Potential FEMA violations
(C) Financial Stability Risk
High retail exposure to volatile assets
No deposit insurance or investor protection
Key Policy Challenges
Absence of:
Dedicated crypto regulator
Consumer protection framework
Risks:
Money laundering
Terror financing
Tax evasion via foreign wallets
Market manipulation
Takeaways
Crypto in India has moved from:
Grey-zone experiment → High-volume taxable asset class
The surge to ₹51,000+ crore shows:
Effective tax collection
But also deep systemic exposure to an unregulated financial instrument

Gallbladder cancer
Why in News?
December 2025: Investigative public health report highlighted Gallbladder Cancer (GBC) as an “invisible epidemic” in India’s Gangetic belt.
Key triggers for national attention:
India contributes ~10% of global GBC burden
~70% of patients are women
Heavy clustering in:
Uttar Pradesh
Bihar
West Bengal
Assam
Strong links established with:
River pollution
Arsenic & heavy metal contamination
Weak cancer surveillance
Governance issues flagged:
Poor environmental enforcement by Central Pollution Control Board
Weak monitoring by Central Ground Water Board
Limited rural reach of the National Cancer Registry Programme
Relevance
GS 2 – Governance
Public health surveillance failure
Environmental governance
Cancer as a non-notifiable disease
Policy neglect of preventable disease clusters
GS 3 – Environment & Health
River pollution
Heavy metal contamination
Environmental cancers
Industrial regulation failures
Groundwater contamination
What is Gallbladder Cancer?
A highly aggressive cancer of the gallbladder
Often asymptomatic in early stages
Detected mostly at Stage III or IV
Medical characteristics:
Rapid local spread
Early liver and lymph node metastasis
Survival:
5-year survival < 10% in advanced disease
Why is GBC Concentrated in the Gangetic Belt?
Geographic clustering along the Ganga River basin
Primary environmental drivers:
Arsenic contamination in groundwater
Cadmium and lead from industrial effluents
Pesticide residues in agriculture
Adulterated mustard oil
Daily exposure routes:
Drinking contaminated groundwater
Consuming polluted river fish
Cooking with unsafe oils
Long latency:
Carcinogenic exposure accumulates silently over decades
Gendered Burden: Why Women are Disproportionately Affected
~70% of GBC patients are women
Contributing factors:
Reuse of cooking oil
Storage of leftover food without refrigeration
Daily exposure to contaminated water during household chores
Nutritional deficiencies
Delayed health seeking due to:
Poverty
Patriarchy
Limited access to diagnostics
Hospital-stage data:
At Tata Memorial Hospital,
>80% of women present at Stage III/IV
Economic & Social Impact
Treatment cost:
₹8–12 lakh per patient
Consequences:
Medical impoverishment
Discontinuation of treatment
Intergenerational poverty cycles
Geographic overlap with:
High multidimensional poverty
Poor sanitation
Gender inequality
Governance Failures at the Core
(A) Environmental Governance
Weak enforcement of:
Water pollution laws
Industrial effluent norms
Continued discharge into rivers
Poor remediation of contaminated aquifers
(B) Health Surveillance Failure
Cancer registries cover <10% of India’s population
NCRP relies heavily on:
Hospital-based reporting
Rural poor remain statistically invisible
Why GBC Remains “Invisible”
Cancer is not a notifiable disease in India
No mandatory cluster reporting
Result:
Delayed detection of regional spikes
No targeted prevention strategy
Low political salience despite high mortality
What Needs to Change?
Make cancer a legally notifiable disease
Integrate:
Health surveillance with National Clean Ganga Mission
Strengthen:
Groundwater testing
Industrial discharge audits
Community-level interventions:
Low-cost screening through district hospitals
Routine water testing
Women-focused awareness campaigns
Develop:
Gender-sensitive cancer policy
Learning from Global Best Practices
Bangladesh:
National Residue Control Program for seafood
Vietnam:
Coastal heavy-metal monitoring
Philippines:
National Residue Monitoring Plan for aquaculture
India’s gap:
Marine Products Export Development Authority residue control applies only to exports, not domestic fish consumption
Public Health Interpretation
GBC in the Gangetic belt represents:
An environmental cancer epidemic
Driven by:
Pollution
Gender disadvantage
Surveillance failure
It is:
Preventable
Detectable early with proper systems
Politically neglected
Takeaway
Gallbladder cancer in the Gangetic belt is:
Not a medical mystery
It is a governance failure in slow motion
The epidemic survives because:
Pollution is tolerated
Women’s health is deprioritised
Cancer is statistically invisible
Declaring cancer notifiable is the single most powerful trigger for reform, as:
What gets counted → gets governed → gets prevented
Conclusion
Gallbladder cancer in the Gangetic belt is an environmental, gendered and governance-driven epidemic — not of biological inevitability, but of regulatory neglect.
