Minecraft wiki entry for Bartering_farm, associated text: An AFK farm is linked to a zombified piglin farm, then it can travel through a hopper system (water currents cannot be used as the nether instantly evaporates it upon placing the water bucket) and drop out of a dropper or dispenser, and collects through a hopper system. To make the farm more effective, make a hopper organizer, as seen in this YouTube video.
