Gold Farm Schematics

Gold farms kill zombified piglins, which drop rotten flesh, gold nuggets and occasionally gold ingots. Zombified piglins spawn in Nether Wastes and Crimson Forest biomes, and in the Overworld from nether portal blocks, so designs either build large spawning platforms in the Nether or stack portal frames in the Overworld.

The largest Java Edition designs are built on the Nether roof, above the bedrock ceiling at Y 128, where the farm's platforms are the only spawnable space nearby. Zombified piglins become angry when one of them is attacked, and many farms use that behaviour to draw them towards a kill point. Like most mobs, they only drop experience when a player kills them, which makes gold farms popular for XP as well as gold.

Zombified piglin behaviour changed in 1.16, so farms built for older versions may not work. A nether roof farm is a large project: compare the number of platforms, the materials list and how the design returns the drops to you before you start.
