dTao Compatible Subnet Deregistration

dTao-Compatible Subnet Deregistration

Background

Since the dTao launch, our existing subnet deregistration (dissolve_network / remove_network) is no longer working correctly.

Subnet Pruning

• Triggered when SubnetLimit is reached
• Step 1: Exclude subnets still within NetworkImmunityPeriod
• Step 2: Among the rest, find the subnet with the lowest current emission
• Step 3: If multiple share the same emission, pick the one with the earliest registration timestamp

Network Dissolution

• In dissolve_network / remove_network, perform full dTao cleanup:
  • Destroy all α-in and α-out stakes
  • Distribute remaining Tao to α-out stakers pro-rata
• Maintain root-only access to direct calls for now

Explicit Subnet Limit

Add new sudo hyperparameter SubnetLimit starting at 128.

High-Level Flow

New Registration → check slot cap?
  ├─ No → register network, grant immunity
  └─ Yes → prune one subnet → deregister → register new
Deregistration (manual or pruning) → destroy α-in/out → distribute Tao → remove network
