# 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](/plian/master/using-the-blockchain/validator-node-guides/setting-up-a-validator-node.md) 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 %}

You are now ready to Register and Vote!

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://pliangroup.gitbook.io/plian/master/using-the-blockchain/validator-node-guides/express-setup.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
