Root network alpha dividends per subnet .

Queried by: validatorsanalyticsdevelopers

The Big Picture

Root network validators (netuid 0) set weights on subnets and earn dividends from those subnets' performance. This tracks how much each root validator earned from each subnet - the economic link between metagovernance and subnet success.

Why This Matters

Root validators govern which subnets get emissions. In return, they earn dividends from subnet success. This creates economic incentive to weight good subnets.

Example Scenario

Query RootAlphaDividendsPerSubnet(netuid=1, hotkey=root_validator) shows how much this root validator earned from subnet 1's operations.

Common Questions

Why do root validators earn from subnets?: Root validators allocate emissions to subnets. They're rewarded for good allocation - weighting successful subnets means higher dividends.
Is this different from AlphaDividendsPerSubnet?: Yes. AlphaDividendsPerSubnet is for validators ON a subnet. This is for ROOT validators earning FROM a subnet through their governance role.

Use Cases

Check root validator earnings from specific subnets
Analyze how subnet performance affects root dividends
Build root network economics dashboards
Research metagovernance incentives
Track capital flows from subnets to root

Code Examples

import { ApiPromise, WsProvider } from "@polkadot/api";
import { stringCamelCase } from "@polkadot/util";

const provider = new WsProvider("wss://entrypoint-finney.opentensor.ai:443");
const api = await ApiPromise.create({ provider });

// Query RootAlphaDividendsPerSubnet storage
const key1 = 0;
const key2 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";

const result = await api.query
