The Big Picture
Like neurons have immunity after registration, new subnets have immunity from dissolution. NetworkRegisteredAt records when the subnet was created. Combined with NetworkImmunityPeriod, it determines if the subnet is still protected.
Why This Matters
Is this subnet still protected from dissolution? Check (current_block - NetworkRegisteredAt) vs NetworkImmunityPeriod. Also shows how established the subnet is.
Example Scenario
Query NetworkRegisteredAt(netuid=18) returns 6500000. Current block is 7000000. Subnet is 500,000 blocks old (~11.5 days). Check if that exceeds NetworkImmunityPeriod.
Common Questions
- What does subnet immunity protect against?
- Dissolution. New subnets can't be removed during immunity, giving them time to establish themselves and attract participants.
- Can I see all subnet creation dates?
- Yes, iterate NetworkRegisteredAt for all netuids to see creation history.
Use Cases
- Check if subnet is still in immunity period
- Calculate subnet age
- Build subnet tenure analytics
- Research subnet creation patterns
- Verify subnet legitimacy through age

MAP ( netuid ) --> block_created
Purpose & Usage
Purpose
Track subnet age for immunity - when did this subnet first appear.
Common Query Patterns
- Query by netuid
- Calculate subnet immunity status
- Research subnet age and tenure
