Incentive scores for neurons on a subnet .

Queried by: minersvalidatorsanalytics

The Big Picture

Incentive is what miners earn. It's derived from rank and determines the miner's share of emissions. High incentive = high earnings. This is the final output that matters for miners - the number that translates directly to TAO rewards.

Why This Matters

How much will your miner earn? Incentive score directly determines emissions. Higher incentive = larger share of the subnet's emission pool.

Example Scenario

Query Incentive(netuid=1, uid=47) returns 0.05 (5% of normalized incentive). If the subnet emits 100 TAO per epoch, this neuron earns approximately 5 TAO.

Common Questions

How is incentive different from rank?: Rank is the raw consensus output. Incentive is the emission-weighted result after applying subnet economics. They're related but not identical.
Do validators have incentive?: Validators receive dividends, not incentive. Incentive is for miners who receive weights.

Use Cases

Check your miner's earning potential
Build emission prediction tools
Analyze incentive distribution fairness
Compare miner performance across subnets

Code Examples

import { createClient, Binary } from "polkadot-api";
import { getWsProvider } from "polkadot-api/ws";
import { sub } from "@polkadot-api/descriptors"; // generated by: npx papi add sub -w wss://entrypoint-finney.opentensor.ai:443

const client = createClient(getWsProvider("wss://entrypoint-finney.opentensor.ai:443"));
const api = client.getTypedApi(sub);

// Query Incentive storage
const netuid = 1;

const result = await api.query.SubtensorModule.Incentive.getValue(netuid);
console.log("Incentive:", result);
