This section will detail the hardware and software needed to run a Pocket node.
Hardware Requirements: 4 CPU’s (or vCPU’s) | 16 GB RAM | 200GB Disk
{% hint style="info" %} These are just the hardware requirements for your Pocket node. You'll also need to run the full nodes of other blockchains, which may have their own hardware requirements that surpass Pocket's. {% endhint %}
There are three ways to install the software you need to run Pocket Network.
Install your dependencies
- go
- go environment GOPATH & GOBIN
- git
Create source code directory
mkdir -p $GOPATH/src/github.com/pokt-network && cd $GOPATH/src/github.com/pokt-network
Download the source code
git clone https://github.com/pokt-network/pocket-core.git && cd pocket-core
Checkout the latest release
{% tabs %} {% tab title="Command" %}
git checkout tags/<release tag>
{% endtab %}
{% tab title="Example" %}
git checkout tags/RC-0.8.2
{% endtab %} {% endtabs %}
Make sure you have $GOPATH setup
{% tabs %} {% tab title="Command" %}
echo $GOPATH
{% endtab %}
{% tab title="Response (Mac)" %}
/Users/<your username>/go
{% endtab %} {% endtabs %}
Build your binary and put it in the $GOPATH/bin directory
{% tabs %} {% tab title="Command" %}
go build -o <$GOPATH/bin directory> <source code directory>/...
{% endtab %}
{% tab title="Example" %}
go build -o $GOPATH/bin/pocket $GOPATH/src/github.com/pokt-network/pocket-core/app/cmd/pocket_core/main.go
{% endtab %} {% endtabs %}
Test your installation
{% tabs %} {% tab title="Command" %}
pocket version
{% endtab %}
{% tab title="Response" %}
> RC-0.8.2
{% endtab %} {% endtabs %}
{% hint style="info" %} Check your version number against the latest release here. {% endhint %}
Install your dependencies
- go
- go environment GOPATH & GOBIN
- Homebrew (Mac or Linux)
Install using Homebrew
brew tap pokt-network/pocket-core && brew install pokt-network/pocket-core/pocket
Test your installation
{% tabs %} {% tab title="Command" %}
pocket version
{% endtab %}
{% tab title="Response" %}

- Reverse Proxy: For SSL termination and request management
- Ports: Expose Pocket RPC (Default :8081) and P2P port (Default: 26656)
- SSL Cert: Required for Validator's serviceURI
ulimit -Sn 16384
{% hint style="warning" %}
This Open Files Limit is set based on the standard config provided with Pocket Core in <datadir>/config/config.json. If you modify your config, you will need to ensure that you modify your Open Files Limit too, according to the formula below.
{% endhint %}
The required ulimit can be calculated using this formula:
({ulimit -Sn} >= {MaxNumInboundPeers} + {MaxNumOutboundPeers} + {GRPCMaxOpenConnections} + {MaxOpenConnections} + {Desired Concurrent Pocket RPC connections} + {100 (Constant number of wal, db and other open files)}
Make sure the server that hosts your node is protected by up-to-date anti-virus and anti-malware software. Protect your node with a firewall but make sure to maintain login access for yourself and keep the above ports open.
