One of the most useful things I've ever created: I found a Piglin Bartering design with automatic storage using shulkers and combined it with Ilmango's classic gold farm.

To activate the farm, just pull the lever in the AFK area. There is another lever below to switch between farming gold blocks or obtaining the Piglin Bartering materials.

If you have questions about the Piglin Bartering part, watch the video I left here from the original creator, who explains everything very well.
