Arweave

Arweave allows users to store data permanently without any fees and that it uses a proof-of-access consensus mechanism and a blockweave data structure. Arweave is more reliable for long-term storage than IPFS. So, we are decide to use Arwearve.

Object Size

All objects have x, y, z size information. When writing Object to Philand, it is performed based on this size information. If there is already an object written on the map, it is considered to be in collision and cannot be written. In addition, it is not possible to exceed the map and must be placed within an 8 * 8.

Writing Object to Philand ex.Size(1,2)

The size is determined when the object is created. It generally does not change.

World Type, Object Theme, Object Type

All objects have a World Type, Object Theme, and Object Type.

• Currently, only "Land" is available for [World Type], but we plan to expand it in the future.

• [Object Theme] represents the basic themes for creating objects, such as Basic, ENS City, Dungeon, and SuperM.

• [Object Type] offers a wide range of options, such as Motorbike, Logo, and Chess Piece. It is added to categorize the objects into common categories.

Using these information, and (x,y,z) coordinates can create potential for extensibility in other games.
