This is the fastest path to a running validator that submits weights on-chain for netuid 100 (src/platform_network/config/settings.py:12).

​
Prerequisites

  • Python 3.12 or newer (pyproject.toml:5).
  • A Bittensor wallet (coldkey + hotkey) registered on netuid 100.
  • The platform CLI installed with its bittensor extra (next step).

​
Get started

1

Install the validator

Install the package with the validator extra, which pulls in bittensor>=9 (pyproject.toml:40).
pip install 'platform-network[validator]'
The install provides the platform command (pyproject.toml:43).
2

Create your config

Copy the example validator config and edit the wallet and network fields.
cp config/validator.example.yaml config/validator.yaml
The example sets netuid: 100 and the validator loop defaults (config/validator.example.yaml:1-22). See Configuration for every field.
3

Point at the registry

registry_url defaults to https://chain.platform.network (config/validator.example.yaml:16). When weights_url is left null, the validator fetches weights from the same registry_url (src/platform_network/config/settings.py:50-52).
4

Run the validator

Start the runtime. It reconciles challenges and submits weights on-chain (src/platform_network/cli_app/main.py:834-854).
platform validator run --config config/validator.yaml
The default config path is config/validator.example.yaml (src/platform_network/cli_app/main.py:835).
5

Confirm it is submitting

The submit loop runs every weights_interval_seconds, which defaults to 360 seconds (config/validator.example.yaml:19, src/platform_network/config/settings.py:45). Watch the logs for weight submission. See Monitoring.

​
Verify the registry connection

Print the live registry the validator reads, to confirm connectivity (src/platform_network/cli_app/main.py:943-948): 
platform registry print --config config/validator.yaml
If the validator infrastructure requirements are too high, you can delegate validation power with Bittensor CHK / stake-weight check instead of running this stack (config/validator.example.yaml:10-13).
