Node Technical Requirements

Node Specifications

These are some recommended specs to a ZetaChain node.

Node Type CPU Memory Data Disk
Observer Signer 8 CPUs 32 GB Memory 300+ GB Data Disk
Core Validator 4 CPUs 16 GB Memory 300+ GB Data Disk

Operating System

ZetaChain nodes have been developed and tested on x86_64 architecture. Our binary files have been compiled with Ubuntu 22.04 LTS x86_64. This guide assumes you are using Ubuntu 22.04 LTS x86_64. If you are using a different OS you may need to make some adjustments.

Getting Started

Set Limits on Open Files and Number of Processes

To better manage the resources of your nodes, we recommend setting some limits on the maximum number of open file descriptors (nofile) and maximum number of processes (nproc).

Edit /etc/security/limits.conf to include or modify the following parameters:

*       soft    nproc   262144 
*       hard    nproc   262144
*       soft    nofile  262144 
*       hard    nofile  262144

Edit /etc/sysctl.conf to include the following:

fs.file-max=262144

Monitoring

In a production environment we recommend monitoring the node resources (CPU load, Memory Usage, Disk usage and Disk IO) for any performance degradation.

Prometheus can optionally be enabled to serve metrics which can be consumed by Prometheus collector(s). Telemetry include Prometheus metrics can be enabled in the app.toml file. See the CosmosSDK Telemetry Documentation for more information.
