The validator ships as part of the platform-network package. Installing it gives you the platform CLI (pyproject.toml:43).

​
Requirements

  • Python 3.12 or newer (pyproject.toml:5).
  • A Bittensor wallet (coldkey + hotkey) for signing on-chain submissions.

​
Install

1

Install with the validator extra

The validator extra installs bittensor>=9, which is required to submit weights (pyproject.toml:40).
pip install 'platform-network[validator]'
2

Confirm the bittensor extra

Submitting weights needs the bittensor dependency. If it is missing, the runtime raises a clear error telling you to install the extra (src/platform_network/bittensor/factory.py:27-28):
pip install 'platform-network[bittensor]'
3

Verify the CLI

Check that the platform command resolves.
platform --help

​
Validator node install (Docker Swarm)

For the submit-only deployment used on the validator node, the supervisor venv provides the Python interpreter, and the wallet lives under /var/lib/platform/wallets/<wallet_name>/hotkeys/<wallet_hotkey> (deploy/swarm/submitter/run_submitter.py:24-28). See The submitter for that path.
The validator node holds the hotkey. Keep the private key off shared hosts and out of logs. The submitter logs only the public hotkey SS58 address (deploy/swarm/submitter/run_submitter.py:65-87).
