TaoFlowCutoff

Storage Plain v334 → v411 Changed in v411

Cutoff threshold for TAO flow calculations.

Queried by: developersanalytics

The Big Picture

Small flows may be ignored in economic calculations. This cutoff defines the minimum flow that affects subnet weight calculations.

Use Cases

Purpose & Usage

Purpose

Minimum flow for economic calculations.

Common Query Patterns

Single value query

Part of: TAO Flow

Stored Value

FixedI128

value (FixedI128)

Decoding the value

FixedI128 (Q64.64 signed fixed-point)

Signed Q64.64. Same divisor as FixedU128 but bits can be negative.

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

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