Become Discoverable by CKB Node Probe
Make sure your internet connection and firewall settings allow for external connections to your node.
Step 1: Locate CKB folder
For Neuron
In the Neuron wallet, go to Settings -> Data -> CKB Node Config & Storage
For CKB mainnet node
Find the installation folder of your CKB mainnet node.
Step 2: Pause your node
For Neuron
Completely close the Neuron wallet. Ensure it's not running in the background.
For CKB mainnet node
Pause the running node.
Step 3: Configure ckb.toml
file
- In the CKB folder(from step 1), locate and open the
ckb.toml
file.
- Scroll down to the [network] section, add the following bootnode entry:
# Observer
"/ip4/52.33.75.45/tcp/8124/p2p/QmPHzhEzekyjB14eQsnsVRxmymtYmAyntcfJgVYRiUq4Lb",
- Review and edit the bootnodes list, keeping a maximum of 3 closest to your location. Here's an example:

- Scroll down to whitelist_peers, remove the # in front, and add the same bootnode entry:
"/ip4/52.33.75.45/tcp/8124/p2p/QmPHzhEzekyjB14eQsnsVRxmymtYmAyntcfJgVYRiUq4Lb"

- Scroll down to max_outbound_peers and change its value to 20.

- Save your changes to the ckb.toml file.
Step 4: Delete peer_store
folder
Within the same CKB folder, navigate to data -> network and delete the peer_store
folder.
Step 5: Restart your CKB node
Re-open the Neuron wallet or reactivate your CKB node to apply the new configurations and ensure your node becomes discoverable by the CKB Node Probe.
Note
If you're on a VPN, your node will show up on the map where your VPN is, not your actual location.
Verfication
To verify the connection to the observer node, paste following command in your web browser's address bar and hit enter:
data:text/html,
<script>
fetch("http://127.0.0.1:8114", {method: "POST", headers:{"Content-Type": "application/json"}, body: '{"id":0,"jsonrpc":"2.0","method":"get_peers","params":[]}'}).then(response => response.json()).then(response => document.write(JSON.stringify(response)));
</script>
Check whether QmPHzhEzekyjB14eQsnsVRxmymtYmAyntcfJgVYRiUq4Lb
is one of your peer nodes.
