set -e, -u, -x, -o pipefail

The set lines

• These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
• With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

• set -euxo pipefail is short for:

set -e
set -u

Baking on Tezos

This document describes how to setup a Tezos node and delegate baking rights to it. It involves configuring two instances:

• Node: Public vps instance that interacts with the tezos network and runs tezos-node, tezos-baker, tezos-endorser and tezos-accuser.
• Signer: Private instance on your home network that contains the baker keys and authorizes baking requests via tezos-signer.

Prep Instances

This guide assumes you have already created two instances running Ubuntu 18.04.
