Setup and Connect a node to the Mainnet

cd ~

git clone _repo_path_

The binary files required to run JuneoGo are:

• juneogo
• jevm
• srEr2XGGtowDVNQ6YgXcdUb16FGknssLTGUFYg7iMqESJ4h8e

To grant execution permissions of the binary files, please execute the following commands:

chmod +x ~/juneogo-binaries/_project_name_
chmod +x ~/juneogo-binaries/plugins/jevm
chmod +x ~/juneogo-binaries/plugins/srEr2XGGtowDVNQ6YgXcdUb16FGknssLTGUFYg7iMqESJ4h8e

After this, the juneogo binary should be moved to the home directory. The remaining two binaries should be moved to the ~/.juneogo/plugins directory.

To do so, please execute the following commands:

mv ~/juneogo-binaries/_project_name_ ~

mkdir -p ~/.juneogo/plugins

mv ~/juneogo-binaries/plugins/jevm ~/.juneogo/plugins
mv ~/juneogo-binaries/plugins/srEr2XGGtowDVNQ6YgXcdUb16FGknssLTGUFYg7iMqESJ4h8e ~/.juneogo/plugins

Create service file

sudo tee /etc/systemd/system/juneod.service > /dev/null <<EOF
[Unit]

After=network.target

[Service]

Start service and check the logs

sudo systemctl daemon-reload && \
sudo systemctl enable juneod && \
sudo systemctl start juneod && \
sudo systemctl status juneod

Wait for synchronization.

Check logs

sudo journalctl -u juneod.service -f --no-hostname -o cat

This will start fetching blocks and bootstrapping your node.

Add a Node to the Validator Set

1. Retrieve Your nodeID, publicKey and proofOfPossession:

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"info.getNodeID"
}' -H 'content-type:application/json' 127.0.0.1:9650/ext/info

Output should look like this:

{
  "jsonrpc": "2.0",
  "result": {
    "nodeID": "NodeID-4JfgcoMWBpxCQL5VmyQ1f6L36mUbLLBga",
    "nodePOP": {
      "publicKey": "MyBLSKey",
      "proofOfPossession": "MyBLSSignature",
    }
  },
  "id": 1
}

2. Copy the value for the nodeID, publicKey, and proofOfPossession from the response.

3. Log into mcnwallet.io.

You can use your own seed phrase to connect or create new for this node project.

4. Go to Stake and open the Validate window.

Enter the Node ID, BLS key, and BLS signature that you previously saved. Add at least 100 JUNE token and set the validation period to at least 90 days.
