Notes

1. Editable vs. Non-Editable
   Many parameters have a corresponding sudo_set_* extrinsic. Those without any listed extrinsic may be read-only or not yet exposed for editing.

2. Permissions

• root: Full-chain access (often associated with the governance root/sudo account).
• sn_owner: Owner (or controller) of a specific subnet.

3. Audience

• Miners: Parties primarily affected in PoW-based registrations or mining operations.
• Validators (Valis): Nodes involved in the validation and weighting process.
• Subnet Owners (sn_owners): Entities that created or manage subnets.
• Potential Subnet Owners: Anyone interested in creating new subnets or controlling them.
• Stakers: Parties that stake tokens or nominate validators.

4. Additional Hyperparameters
   Some extrinsics, such as sudo_set_default_take or sudo_set_subnet_owner_cut, may govern additional economics or reward distribution parameters not explicitly detailed in the snippet above. Where a parameter is not shown in the table, it may be network-specific, newly introduced, or simply not documented here.

5. Getting Current Values
   To view the current hyperparameter values for a subnet, use:

btcli subnet hyperparameters

Then select the appropriate netuid (subnet ID).

6. Setting Hyperparameters
   To set any hyperparameter that is editable, you typically use:

btcli sudo set ...

which will internally call the relevant sudo_set_* extrinsic, assuming you have the required permissions.

---

Quick Examples

• Setting MaxWeightLimit (as sn_owner):

  btcli sudo set --key <sn_owner_key> --netuid <subnet_id> max_weight_limit 700
• Setting Tempo (as root):

  btcli sudo set --key <root_key> --netuid <subnet_id> tempo 120

(Ensure your wallet/key has the proper on-chain privileges: root or sn_owner.)
