Node Registration

This guide walks you through registering your Bittensor full-archive node on the FlameWire network.

Prerequisites

Before registering, ensure you have:

• A full-archive Bittensor node running and fully synced
• Your node must be online and accessible from the internet
• A Bittensor wallet with a registered hotkey on subnet 97
• The btcli command-line tool installed

On the node machine, install signing dependencies:

sudo apt install -y libclang-dev clang curl build-essential
cargo install subkey --git https://github.com/paritytech/polkadot-sdk

Node Configuration

Your node must be properly configured before registration:

Registration Steps

Step 1: Access the FlameWire Dashboard

Navigate to the FlameWire application and sign in with your Google account:

FlameWire App

After signing in, you'll be redirected to the My Nodes page with the registration modal already open.

Step 2: Enter Your Node URL and Hotkey

In the registration modal, enter your node's WebSocket endpoint and your hotkey.

ws://your_node_ip:9944

Or if you have SSL configured:

wss://your_node_domain:9944

Step 3: Sign the Registration Message

Sign the verification message on the node machine using the node key (not the wallet hotkey):

echo -n "verify:[hotkey]" | subkey sign \
  --scheme ed25519 \
  --suri "0x$(cat /path-to/chains/bittensor/network/secret_ed25519 | xxd -p -c 32)"

Replace the placeholders with your actual values:

• [hotkey] — Your SS58 hotkey address (starts with 5)
• /path-to/chains/bittensor/network/secret_ed25519 — Your node key file path

Example:

echo -n "verify:5ExampleHotkeyAddress" | subkey sign \
  --scheme ed25519 \
  --suri "0x$(cat /var/lib/bittensor/chains/bittensor/network/secret_ed25519 | xxd -p -c 32)"

Step 4: Complete the Registration

Paste the values into the modal:

1. Hotkey — Your Bittensor hotkey address (starts with 5)
2. Signature — The signature output from the subkey sign command

Click + Register Node to complete the registration.

Node Verification

After registration, FlameWire performs automatic verification:

• Connectivity check — Ensures your node is reachable
• Sync status — Verifies your node is fully synced
• Archive data — Confirms historical block data is available

You can monitor your node's status in the dashboard. A Healthy status indicates your node is ready to receive traffic.

You can also track miner status on the subnet metagraph:

btcli subnet metagraph --subtensor.network finney --subnet.netuid 97
