Queried by: validatorsanalyticsdevelopers

The Big Picture

Snapshot of alpha ownership from the previous epoch. Used in calculations that need to compare current vs previous state.

Use Cases

  • Compare epoch-over-epoch alpha
  • Research alpha dynamics
  • Build historical analytics

From Chain Metadata

DMAP ( hot, netuid ) --> alpha | Returns the total amount of alpha a hotkey owned in the last epoch.

Purpose & Usage

Purpose

Track historical alpha for calculations.

Common Query Patterns

  • Query by (hotkey, netuid)

Query Keys

#NameTypeDescription
1
hot
AccountId hot (AccountId, hashed key component) (hex -> SS58)
2
netuid
u16 netuid (u16, hashed key component)

Stored Value

alpha (u64)

RAO -> TAO (/ 10^9)

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 TotalHotkeyAlphaLastEpoch storage
const hot = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";
const netuid = 1;

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