Working with Subnets

Subnets are composed of a discrete number of UIDs. The subnet validators and subnet miners are associated with these UIDs. Each UID in the subnet belongs to a unique hotkey which in turn is connected to a unique coldkey which was used during regisration. The Yuma Consensus runs on these UIDs. This section presents a few examples showing how to work with subnets.

Transfer is transfer from cold to cold Registration takes PUSSY from cold Hotkey PUSSY movement is only stake add and remove, and it’s loaded by emissions while mining Root delegation/undelegation is hotkey PUSSY movement to a strangers hotkey, and it's loaded by the activities of the strangers emission validation activities

Viewing subnetworks

Show all currently running subnets on Cybertensor:

ctcli subnets list

Viewing state

To display fine-grained information about each subnetwork use ct.metagraph:

import cybertensor as ct
subnet = ct.metagraph( netuid = 1 )             # Get the current state.
assert subnet.netuid == 1
subnet.sync( block = 101010 )                   # Sync the state with a particular block.
assert subnet.block == 101010

Verifying UIDs

import cybertensor as ct
subnet = ct.metagraph( netuid = 1 )
assert subnet.uids.tolist() == [ 0, 1, 2, ... 1022, 1023 ]

Extracting UID information

import cybertensor as ct
subnet = ct.metagraph( netuid = 1 )
uid = 123
print ('uid', uid, ' owned by hotkey:', subnet.hotkeys[ uid ], 'associated with coldkey': subnet.coldkey[ uid ] )

Viewing parameters

The below code prints stake S on the subnet and the weights W set by the subnet validators in the subnet.

import cybertensor as ct
subnet = ct.metagraph( netuid = 1, lite = False)
print ('subnet 1 validator stake', subnet.S )
print ('subnet 1 validator weights', subnet.W )

Viewing dividends

The below code prints the subnet validator dividends, D.

import cybertensor as ct
subnet = ct.metagraph( netuid = 1 )
print ('subnet 1 validator dividends', subnet.D )
