Economics of Supply

Economics of Supply (EOS) adds an economy system to minecraft via the Altar block. At the altar, players can offer valuable items to an unknown entity in exchange for currency. The price paid for the item is determined by a demand curve. As quantity supplied increases, price offered will decrease. Demand curves and currencies are configured via datapacks.

Quantity supplied is averaged across a configurable number of intervals with a configurable duration in ticks. For example: The average number of diamond sold each Minecraft day (24000 ticks) over the past 7 days. This value is plugged into the demand curve for that item to determine the price offered.

The mod also includes a price ticker. Players can set a price ticker to a track a particular item and a price floor for that item. If the price of the tracked item falls below the set price floor, the price ticker will emit a redstone signal that can prevent an altar from selling.

This is meant primarily as a tool for modpack devs. By default, the mod only includes demand curves for a few items with emeralds set as the currency paid out.
