Mining on Bittensor

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:

1 git clone https://github.com/opentensor/bittensor-subnet-template.git

Next, cd into bittensor-subnet-template repo directory:

1 cd bittensor-subnet-template # Enter the

Install the bittensor-subnet-template package:

1 python -m pip install -e .

2. Create wallets #

Create wallets for subnet owner, subnet validator and for subnet miner.

Follow all of these steps:

1 btcli wallet new_coldkey --wallet.name owner

Create a coldkey and hotkey for your miner wallet:

1 btcli wallet new_coldkey --wallet.name miner

and

1 btcli wallet new_hotkey --wallet.name miner --wallet.hotkey default

Create a coldkey and hotkey for your validator wallet:

1 btcli wallet new_coldkey --wallet.name validator

and

1 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.

1 btcli subnet lock_cost --subtensor.network test

The above command will show:

1 >> 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:

btcli w list

You will get an output like this:

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 #

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.

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:

1 btcli subnet register --netuid 15 --subtensor.network test --wallet.name miner --wallet.hotkey default

Follow the below prompts:

1 2 3 4 5 6 >> 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:

1 btcli subnet recycle_register --netuid 15 --subtensor.network test --wallet.name validator --wallet.hotkey default

Follow the prompts:

1 2 3 4 5 6 >> 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:

1 btcli wallet overview --wallet.name miner --subtensor.network test

The above command will display the below:

1 2 3 4 5 Subnet: 1 COLDKEY HOTKEY UID ACTIVE STAKE(τ) RANK TRUST CONSENSUS INCENTIVE DIVIDENDS EMISSION(ρ) VTRUST VPERMIT UPDATED AXON HOTKEY_SS58 miner default 1 True 0.00000 0.00000 0.00000 0.00000 0.00000 0.00000 0 0.00000 14 none 5GTFrsEQfvTsh3WjiEVFeKzFTc2xcf… 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:

1 python neurons/miner.py --netuid 15 --subtensor.network test --wallet.name miner --wallet.hotkey default --logging.debug

You will see the below terminal output:
