​
On-Chain Asset

Assets that are created by a third party with the existence attested on a blockchain network supported by the Asset Register. The Asset Register can only interact with these assets through the interface provided by the smart contract or runtime module on the blockchain where the asset is located. Therefore, it is imperative that asset collections deployed on the respective networks adhere to the NFT specifications.

​
Off-Chain Asset

Assets that are created by a third party and attested by the third party’s system. Therefore, the third party is the creator and has superuser access over all their off-chain assets. Each asset must be registered on the Asset Register and registered against a schema to be a valid off-chain asset.
A link between two assets (parent and child) based on a relationship path e.g. equippedWith_gloves. The Asset Register uses these relationships to build the asset trees that describe an asset.

​
Asset Schema

Describes the properties of an asset and its compatibility with other assets through asset links. Schemas should be stored in a globally accessible and permanent location and be registered against an asset. The Asset Register will provide internal Futureverse teams with the ability to store schemas on a Futureverse namespace.

HairStyle Example

​
Turtle Syntax

Turtle syntax is used to create the schemas.
