LoadedEmission

Storage Map v101 → v411 · 1 shape change Changed in v411

Preloaded emission data for a subnet .

Queried by: validatorsdevelopers

The Big Picture

Emission calculations are preloaded and cached here before distribution. Contains (hotkey, server_emission, validator_emission) tuples ready to be applied.

Use Cases

Debug emission distribution
Monitor emission calculations
Build emission analytics

From Chain Metadata

MAP ( netuid ) --> (hotkey, se, ve)

Purpose & Usage

Purpose

Cache emission calculations for efficient distribution.

Common Query Patterns

Query by netuid

Migration Notes

v120 v121 Breaking

value type changed from Vec<(AccountId, u64)> to Vec<(AccountId, u64, u64)>

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.

Query Keys

#	Name	Type	Description
1	netuid	u16	netuid (u16, hashed key component)

Stored Value

Vec<(AccountId, u64, u64)> Vec

(hotkey, (Vec<(AccountId, u64, u64)>)

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 LoadedEmission storage
const netuid = 1;

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