Vast internal guide to test subnets inside the Opentensor image

This tutorial shows how to use the Bittensor testnet to create a subnet and run your incentive mechanism on it.

​
1. Install Bittensor subnet template

cd into your project directory and clone the bittensor-subnet-template repo:
Bash
git clone https://github.com/opentensor/bittensor-subnet-template.git
Next, cd into bittensor-subnet-template repo directory:
Bash
cd bittensor-subnet-template # Enter the
Install the bittensor-subnet-template package:
Bash
python -m pip install -e .

​
2. Create wallets

Create wallets for subnet owner, subnet validator and for subnet miner. Follow all of these steps:
Bash
btcli wallet new_coldkey --wallet.name owner
Create a coldkey and hotkey for your miner wallet:
Bash
btcli wallet new_coldkey --wallet.name miner
and
Bash
btcli wallet new_hotkey --wallet.name miner --wallet.hotkey default
Create a coldkey and hotkey for your validator wallet:
Bash
btcli wallet new_coldkey --wallet.name validator
and
Bash
btcli wallet new_hotkey --wallet.name validator --wallet.hotkey default

​
3. Get the price of subnet creation

Creating subnets on the testnet is competitive. The cost is determined by the rate at which new subnets are being registered onto the chain.
Bash
btcli subnet lock_cost --subtensor.network test
The above command will show:
Bash
>> Subnet lock cost: τ100.000000000

​
4 Go to the Bittensor discord channel and ask them for test Taos

Here is the link to the discord channel for Bittensor.

​
4.5 Transfer test Taos to your miner wallet

Use the following command to list all your wallets:
Text
    btcli w list
You will get an output like this:
Text
    Wallets
    ├── 
    │   owner (5FyRdpzddeN7KGLhn6S6ia1up7dzbtXiZ5trc2hmm9AN9Pj4)
    ├── 
    │   miner (5GCahkVacWRHzVgRBfSmnt11gHnWWZhkapquzPEwR7je1a8w)
    │   └── default (5CUgZBi3GQpJDhe1EhdPJfzBb6pyWvnkuSWJ6SBhEpSby1XP)
    └── 
        validator (5FZSLAZsiFaZzhcL2oxMesSrQQHmWHSGpPfNjMUmiruBpYGB)
        └── default (5EqaFbjHDUQCHRbG5592QvCbpNkvAxsLCLKRNoLaVLN76g55)
Then transfer 0.001 Taos to your miner and validator wallet.

​
Transfer to miner wallet

Text
    btcli wallet transfer --dest 5GCahkVacWRHzVgRBfSmnt11gHnWWZhkapquzPEwR7je1a8w --wallet.name owner --amount 0.001 --subtensor.network test
Make sure the —dest key is the same as your wallet key that you get from the btcli w list command.

​
Transfer to validator wallet

Repeat this step for the validator wallet as well.
Text
    btcli wallet transfer --dest 5FZSLAZsiFaZzhcL2oxMesSrQQHmWHSGpPfNjMUmiruBpYGB --wallet.name owner --amount 0.001 --subtensor.network test

​
6. Register keys

This step registers your subnet validator and subnet miner keys to the subnet, giving them the first two slots on the subnet. Register your miner key to the subnet:
Bash
btcli subnet register --netuid 15 --subtensor.network test --wallet.name miner --wallet.hotkey default
Follow the below prompts:
Bash
>> Enter netuid [1] (1): # Enter netuid 1 to specify the subnet you just created.
>> Continue Registration?
  hotkey:     ...
  coldkey:    ...
  network:    finney [y/n]: # Select yes (y)
>> ✅ Registered
Next, register your validator key to the subnet:
Bash
btcli subnet recycle_register --netuid 15 --subtensor.network test --wallet.name validator --wallet.hotkey default
Follow the prompts:
Bash
>> Enter netuid [1] (1): # Enter netuid 1 to specify the subnet you just created.
>> Continue Registration?
  hotkey:     ...
  coldkey:    ...
  network:    finney [y/n]: # Select yes (y)
>> ✅ Registered

​
7. Check that your keys have been registered

This step returns information about your registered keys. Check that your miner has been registered:
Bash
btcli wallet overview --wallet.name miner --subtensor.network test
The above command will display the below:
Bash
Subnet: 1                                                                                                                                                                
COLDKEY  HOTKEY   UID  ACTIVE  STAKE(τ)     RANK    TRUST  CONSENSUS  INCENTIVE  DIVIDENDS  EMISSION(ρ)   VTRUST  VPERMIT  UPDATED  AXON  HOTKEY_SS58

1        1        2            τ0.00000  0.00000  0.00000    0.00000    0.00000    0.00000           ρ0  0.00000                                                         
                                                                          Wallet balance: τ0.0

​
8. Run subnet miner and subnet validator

Run the subnet miner:
Bash
python neurons/miner.py --netuid 15 --subtensor.network test --wallet.name miner --wallet.hotkey default --logging.debug
You will see the below terminal output:
Bash
2024-01-22 17:34:42.694 |       INFO       | Miner running...              1705944882.6945262
