RegistrationsThisInterval

Storage Map v101 → v411

Registrations in current adjustment interval.

Queried by: minersvalidatorsdevelopersanalytics

The Big Picture

This counter tracks how many registrations have happened since the last difficulty adjustment. At each AdjustmentInterval, it's compared to TargetRegistrationsPerInterval to determine whether costs should increase or decrease.

Why This Matters

Will registration get cheaper or more expensive? Compare this to TargetRegistrationsPerInterval. Above target = costs rising. Below = costs falling.

Example Scenario

Query RegistrationsThisInterval(netuid=1) returns 5. Target is 3. We're 67% above target, so expect difficulty and burn to increase at the next adjustment.

Common Questions

When does this reset?: At each AdjustmentInterval. After difficulty adjusts, the counter resets to zero for the next interval.
Does this include both POW and burn?: Yes, this is total registrations. Check POWRegistrationsThisInterval and BurnRegistrationsThisInterval for the breakdown.

Use Cases

Predict whether costs will increase or decrease
Monitor registration activity in real-time
Research registration patterns
Build registration activity dashboards
Plan registration timing
