Economic spam prevention for commitment registration .
Current Value
0 TAO (0 raw)
Conversion: ÷ 10^9 (RAO → TAO)
Relevant for: validatorsminersdevelopers
The Big Picture
Like identity registration, commitments may require a deposit to prevent spam. This is the base deposit for creating a commitment. Currently set to 0 on Bittensor, meaning no deposit required.
Why This Matters
Check if a deposit is required before committing. If non-zero, you need this TAO reserved.
Example
InitialDeposit is 0. You can create commitments without locking any TAO for deposit.
Common Questions
- Do I get the deposit back?
- Yes, when you clear or replace your commitment, the deposit is returned.
From Chain Metadata
The amount held on deposit for a registered identity
Use Cases
- Calculate deposit needed for first commitment
- Plan budget for commitment operations
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 InitialDeposit constant
const value = api.consts[stringCamelCase("Commitments")][stringCamelCase("InitialDeposit")];
console.log("InitialDeposit:", value.toHuman());
// Convert RAO to TAO if this is a balance value
const taoValue = value.toBigInt() / BigInt(1e9);
console.log("TAO:", taoValue.toString());Type Information
