The Big Picture
Childkeys allow stake delegation hierarchies. This burn cost prevents spam creation of childkey relationships. The burned TAO is removed from circulation.
Use Cases
- Calculate cost of setting childkeys
- Plan childkey hierarchy expenses
- Build childkey management tools
From Chain Metadata
ITEM --> CK burn
Purpose & Usage
Purpose
Cost in RAO to create childkey relationships.
Common Query Patterns
- Single value query
Stored Value
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 CKBurn storage (no keys - plain value)
const result = await api.query.SubtensorModule.CKBurn.getValue();
console.log("CKBurn:", result);Runtime Info
