AdminFreezeWindow

Storage Plain v320 → current

Window length at tempo end during which admin operations are frozen.

Queried by: subnet ownersvalidatorsdevelopers

The Big Picture

To ensure fair epochs, admin operations (hyperparameter changes) are frozen near tempo boundaries. This storage defines that freeze window length in blocks. Changes attempted during the freeze will fail.

Use Cases

Plan hyperparameter changes around freeze windows
Understand when admin operations are blocked
Build admin tooling aware of freeze periods

From Chain Metadata

Global window (in blocks) at the end of each tempo where admin ops are disallowed

Purpose & Usage

Purpose

Prevent hyperparameter changes near epoch boundaries.

Common Query Patterns

Single value query

Stored Value

Code Examples

import { ApiPromise, WsProvider } from "@polkadot/api";
import { stringCamelCase } from "@polkadot/util";

const provider = new WsProvider("wss://entrypoint-finney.opentensor.ai:443");
const api = await ApiPromise.create({ provider });

// Query AdminFreezeWindow storage (no keys - plain value)
const result = await api.query
  [stringCamelCase("SubtensorModule")]
  [stringCamelCase("AdminFreezeWindow")]();
console.log("AdminFreezeWindow:", result.toHuman());
