Call v138 → v277, v290 → current #26Sets the bonds moving average parameter for a subnet .
View calls on chainCall Workflow
This diagram shows the call execution flow: starting with sudo_set_bonds_moving_average, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch and modifies storage: SubtensorModule.BondsMovingAverage, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.

Used by: subnet owners
The Big Picture
Controls how fast the bonds between validators and miners update. Higher values mean slower, smoother changes.
Use Cases
- Tuning bond responsiveness
- Stabilizing validator-miner relationships
From Chain Metadata
The extrinsic sets the bonds moving average for a subnet. It is only callable by the root account or subnet owner. The extrinsic will call the Subtensor pallet to set the bonds moving average.
