SubnetProtocolFlow

Storage Map v411 → current New

Per-block accumulator for protocol cost per subnet (emission + chain buys - root sells). MAP (netuid ) → i64.

Queried by: analyticsdevelopers

The Big Picture

The raw signed accumulator that gets EMA-smoothed into SubnetEmaProtocolFlow and then deducted from emission shares when NetTaoFlowEnabled is on.

Use Cases

Reconstruct protocol cost adjustments to emission shares
Track protocol cost trends per subnet

From Chain Metadata

MAP ( netuid ) --> subnet_protocol_flow | Per-block accumulator for protocol cost (emission + chain buys - root sells).

Purpose & Usage

Purpose

Signed-integer running flow used by net-TAO-flow accounting.

Common Query Patterns

Query SubnetProtocolFlow[netuid]

Part of: Net TAO Flow Accounting

Query Keys

#	Name	Type	Description

subnet_protocol_flow (i64)

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 SubnetProtocolFlow storage
const netuid = 1;

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