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

Used by: subnet owners
The Big Picture
Some subnets can have multiple consensus mechanisms. This controls the count.
Use Cases
- Multi-mechanism subnets
- Advanced subnet configuration
From Chain Metadata
Sets the desired number of mechanisms in a subnet
Input Parameters

Root
Required Role
Permission data inferred from metadata. May be incomplete.
Requirements

- Subnet exists
Effects
Storage Modified
Postconditions
- MechanismCount updated
Side Effects
