Introduction

This is a not official recommendations for Linux based pool nodes. This, is my node's config which runs on Ubuntu 18.04.3 LTS (Bionic Beaver) server (/w Jormungandr v0.8.4) and does not have any issues at all, since the changes.

Before the change of the settings to these below, my node was struggling and missed almost all of the leaders' time due to the forks that caused by not having the latest tip/blocks.

After, I changed the settings, I have not missed any schedule for creating blocks.

# This script monitors a Jormungandr node for "liveness" and executes a shutdown if the node is determined
# to be "stuck". A node is "stuck" if the time elapsed since last block exceeds the sync tolerance 
# threshold. The script does NOT perform a restart on the Jormungandr node. Instead we rely on process 
# managers such as systemd to perform restarts.

There are two keypairs that are required to register a pool:

1. reward account (costs and rewards) and
2. owner stake (pledge) keypair.
