The map divides the entire surface of the Earth into Places where Players can slap Stickers. Places are rectangles 0.01° wide and 0.01° tall. Only the most recent Slap at each Place is visible on the map by default.
Players can create Slaps anywhere on Earth using any active Stickers in the game. The record of a Player slapping a Sticker on a Place is called a Slap. Slaps exist forever, even after they are covered by other Slaps at the same Place.
Stickers are images which Players can slap on the Board. Players may create Slaps with any active Sticker, with the exception of Stickers that are limited to players with a non-zero balance in an external contract.
The account that creates a new Sticker in StickerChain is its Publisher. The Publisher receives half the protocol fees every time a Player slaps their Sticker. They can also set a premium price for their Sticker. The Publisher is responsible for the Sticker content following the game rules (no IP infringement, no sexual content, etc).
Each Objective is an external contract which implements a sub-game inside StickerChain. When a Player slaps stickers they can optionally choose to attach an Objective to their Slaps. The logic of the Objective contract determines additional functionality for the Slaps passed to it. Initially only the admin can create new Objectives, but in the future Objectives will be able to be created permissionlessly.
