# Express Node Setup Guide

This is for those that are familiar with the software. For a more in-depth guide, continue onto the [Setting Up a Validator Node](https://pliangroup.gitbook.io/plian/master/using-the-blockchain/validator-node-guides/setting-up-a-validator-node) page.

Install, Download Bootstrap, and Run:

```
LOCATION=$(curl -s https://api.github.com/repos/pchain-org/pchain/releases/latest | grep "tag_name" | awk '{print "https://github.com/pchain-org/pchain/releases/download/" substr($2, 2, length($2)-3) "/pchain_mainnet_" substr($2, 2, length($2)-3) ".tar.gz"}') ; curl -L -o pchain_mainnet.tar.gz $LOCATION
mkdir -p pchain_main ; tar xzf pchain_mainnet.tar.gz --one-top-level=pchain_main --strip-components 1
mkdir -p pchain/log pchain/bin pchain/.pchain pchain/scripts
cp ~/pchain_main/pchain ~/pchain/bin/
cp ~/pchain_main/run.sh ~/pchain/
cd pchain
wget https://pchainblockdata.s3-us-west-2.amazonaws.com/blockDataWithChild.tar.gz
tar -xzf blockDataWithChild.tar.gz
~/pchain/run.sh
```

Start Auto-update Scripts:

```
sudo apt-get install jq -y
cd ~
cp ~/pchain_main/pchain.cron ~/pchain/scripts/
cp ~/pchain_main/scripts/* ~/pchain/scripts/
sudo crontab ~/pchain/scripts/pchain.cron 
crontab -l
```

Create New Address:

```
~/pchain/bin/pchain attach ~/pchain/.pchain/pchain/pchain.ipc
```

Then once that opens the console, generate a new address:

```
personal.newAccount()
```

{% hint style="danger" %}
Make sure to back this information up! Losing this is losing your rewards and balance.
{% endhint %}

Once that is complete, type `exit` to exit. 

Then generate a BLS Key:

```
~/pchain/bin/pchain --datadir ~/pchain/.pchain gen_priv_validator your_address
cp ~/pchain/.pchain/priv_validator.json ~/pchain/.pchain/pchain/
cp ~/pchain/.pchain/priv_validator.json ~/pchain/.pchain/child_0/
kill $(pidof pchain)
~/pchain/run.sh
```

{% hint style="danger" %}
Make sure to backup this key as well! Losing this means you would have to reregister and potentially lose validation time. 
{% endhint %}
