This storage item was removed in v195
This storage item is no longer available in the current runtime. Existed from v161 to v165. Shown here for historical reference.
BaseDifficulty
Storage Removed Plain v161 → currentPurpose & Usage
Purpose
Stores chain state data.
Common Query Patterns
- Query by key
- Iterate all entries
Stored Value
Value in RAO (÷10⁹ for TAO)
RAO -> TAO (/ 10^9)
Default Value
10000000 0x8096980000000000
Absent keys read as this value — querying a key that has never been written returns this default, not an error or empty result.
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 BaseDifficulty storage (no keys - plain value)
const result = await api.query.SubtensorModule.BaseDifficulty.getValue();
console.log("BaseDifficulty:", result);Runtime Info
