Split alpha_out (owner / miners / validators)
最后审阅于 2026-10-16
This page shows how a subnet's alpha_out is divided among participants, then points to the rest of the flow.
The alpha_out split (1 α/block)
Each subnet has its own split, stored on chain as SubnetEmissionWeights. New subnets start on the default:
- Subnet owners receive 18% of subnet emission.
- Miners receive 41% of emissions.
- Validators receive 41% of emissions — which is then further divided amongst their stakeholders (steps 4–6).
Per-subnet splits
The subnet owner can change the split once every 50,400 blocks (about 7 days), within these limits:
| Share | Allowed |
|---|---|
| Owner | 0% to 33% (lease subnets: at least 18%) |
| Validators | at most 50%, and at least the subnet's validator floor |
| Miners | at least 33% |
Root TAO stakers keep their baseline share of the subnet's emission whatever split the owner picks: the chain sets a per-subnet TAO weight (SubnetTaoWeight) to hold it level. A cut to the validator share comes out of alpha stakers' dividends. The validator floor is the lowest validator share at which that still works. Full rules and the formulas: eTao.
To read a subnet's current split, use the get_subnet_emission_weights runtime API, or btcli subnets emission show --netuid <netuid>.
What's next
Step 4 — Parent / child hotkeys: aggregate each validator's dividends across its parent and child hotkeys. Then:
- Step 5: Root vs alpha split — divide the validator's dividends into root and alpha proportions.
- Step 6: award stakeholder rewards — root and alpha.
