This diagram shows the call execution flow: starting with enable_voting_power_tracking, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch which emits events: VotingPowerTrackingEnabled, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.

From Chain Metadata
Enables voting power tracking for a subnet. This function can be called by the subnet owner or root. When enabled, voting power EMA is updated every epoch for all validators. Voting power starts at 0 and increases over epochs.
Migration Notes
v424 v432 Breaking
netuid changed from u16 to NetUid
Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.
Input Parameters
| # | Name | Type | Description |
