FlowNormExponent

Storage Plain v334 → v411 Changed in v411

Normalization exponent for TAO flow calculations.

Queried by: developersanalytics

The Big Picture

The flow normalization exponent (p) affects how TAO flow values are scaled. Part of the economic formula determining subnet weight based on flow dynamics.

Use Cases

Understand flow normalization
Research subnet economics

ITEM --> Flow Normalization Exponent (p)

Purpose & Usage

Purpose

Control flow normalization in subnet economics.

Common Query Patterns

Single value query

Part of: TAO Flow

Stored Value

FixedU128

value (FixedU128)

Decoding the value

FixedU128 (Q64.64 fixed-point)

FixedU128 encodes as Q64.64: raw bits divided by 2^64 gives the rational. Magnitude > 0 means non-zero.

const fraction = Number(value as bigint) / 2 ** 64;

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 FlowNormExponent storage (no keys - plain value)
const result = await api.query.SubtensorModule.FlowNormExponent.getValue();
console.log("FlowNormExponent:", result);
