-#!/usr/bin/env bash
-# Demonstrate the creation and usage of UTXO snapshots.
-#
-# A server node starts up, IBDs up to a certain height, then generates a UTXO
-# snapshot at that point.
-#
-# The server then downloads more blocks (to create a diff from the snapshot).
-#
-# We bring a client up, load the UTXO snapshot, and we show the client sync to
-# the "network tip" and then start a background validation of the snapshot it
-# loaded. We see the background validation chainstate removed after validation
-# completes.
-#
-# The shellcheck rule SC2086 (quoted variables) disablements are necessary
-# since this rule needs to be violated in order to get bitcoind to pick up on
-# $EARLY_IBD_FLAGS for the script to work.
