### **Landmark Types**

There are four types of landmarks: Regular, Official, Special, and Certified. \
The distinctions lie in map display, initial level, initial price, and output. Levels range from 1 to 30, with the system currently open up to level 20. Outputs vary accordingly:

* **$POTATO:** This token is used to incentivize landowners within the ecosystem, with a total supply of 10 billion. The initial liquidity is 1%, and the remaining portion is entirely produced by the land. \
  $POTATO are designed to incentivize non-financial contributions within the ecosystem, such as check-ins, likes, photo uploads, and comments. They are non-transferable but can be used to purchase services or props, like discounts, memberships, and powerful effect props.
* **Props:** Available through in-app purchases and airdrops, props provide special rights or special effects within the game. The specific list of props is forthcoming.
