The Big Picture
Subnet owners invest significant TAO (lock cost) and effort (building the validation mechanism). This constant sets what percentage of subnet emissions they receive as compensation. It's a tax on miners/validators that funds subnet development and maintenance. Higher cuts incentivize subnet creation but reduce participant earnings.
Why This Matters
As a miner or validator, this percentage is taken from emissions before you're paid. As a subnet owner, this is your revenue. Factor it into ROI calculations.
Example
With InitialSubnetOwnerCut of 900 (9%), if a subnet generates 100 TAO in emissions, 9 TAO goes to the subnet owner, 91 TAO is distributed to miners and validators based on their weights/stake.
Common Questions
- Can subnet owners change their cut?
- The current implementation sets this at registration time. Governance may adjust network-wide limits, but individual subnet cuts are typically fixed.
- Is owner cut taken from miner or validator share?
- It's taken from total subnet emissions before the miner/validator split. Both groups effectively pay the tax proportionally.
Use Cases
- Emission distribution
- Owner rewards
