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

The Big Picture
Net TAO flow is the v411 mechanism for charging protocol cost (emission + chain buys - root sells) against a subnet's emission share before distribution. This switch toggles the whole accounting model at the network level.
Use Cases
- Switch the network between gross and net flow accounting
- Roll back to gross flow if net accounting causes issues
From Chain Metadata
Enables or disables net TAO flow (protocol cost deduction from emission shares). When enabled, emission shares use net flow = user flow - protocol cost. When disabled, emission shares use gross user flow only (current behavior).
Input Parameters
| # | Name | Type | Description |
|---|---|---|---|
| 0 | enabled | bool | True to use net TAO flow (subtract protocol cost) in emission share calculation; false for gross flow |
