TargetRegistrationsPerInterval

Storage Map v101 → v411

Target registrations per adjustment interval.

Queried by: minersvalidatorssubnet ownersdevelopersanalytics

The Big Picture

The system adjusts difficulty to achieve this target registration rate. If actual registrations exceed target, costs rise to reduce demand. Below target, costs fall to encourage registration. It's the thermostat setting for registration economics.

Why This Matters

Will registration costs go up or down? Compare RegistrationsThisInterval to this target. Above target = costs rising. Below target = costs falling.

Example Scenario

Query TargetRegistrationsPerInterval(netuid=1) returns 3. The system aims for 3 registrations per interval. If there were 5, expect costs to increase at next adjustment.

Common Questions

Why have a target?: Controls subnet growth rate. Too fast = chaotic. Too slow = stagnation. The target balances turnover with stability.
Can this change?: Yes, subnet owners can adjust. Higher target = faster turnover, more accessibility. Lower target = slower turnover, higher costs.

Use Cases

Predict whether costs will increase or decrease
Understand subnet growth targets
Research registration economics
Design subnet turnover parameters
Build registration timing tools
