T&T’s conceptual model

Game, World

The game is T&T itself. The game contains multiple worlds, and each world corresponds to a project that uses T&T.

Player

Players are the users of T&T and the members who participate in each project.

Token

T&T has tokens called base NFTs.

Base NFTs, also called character NFTs or membership NFTs, serve as a kind of pass for accessing the T&T universe. There is one contract per world.

Check-in Record (CheckInLog)

A check-in log is recorded when a player checks in, and serves as a record of the player’s activity. For a regional project, it might be a record of participation in a festival; for a blockchain game, it might be a record of clearing a dungeon.

In T&T, items can be granted to a player upon check-in.

Item (InventoryItem)

Items are owned by players and are granted in return for participation in and contribution to a world. An item may be a dress-up item that decorates a token, or it may represent an owned quantity, such as in-world currency (Credit) or experience points.

Equipment

Equipment is the setting of an item a player possesses onto a token. By equipping items, the base NFT can be dressed up, and items can also be expressed as special badges or attributes.

Characteristics

T&T separates the concepts of player and token so that it can express both what requires holding a token and what can be done without one. This is intended to enable a freemium-like mechanism in which players take part in a world’s activities and, once they come to support those activities, obtain an NFT to participate more deeply.
