Items
What are Digital Items?
Digital Items are individual, ownable objects stored by the Marble contract. A Digital Item can represent anything from a trading card to a deed of ownership to an in-game spaceship.
Upon creation, every Item is given a unique contract-wide serial number used to identify it among all other Items in the contract.
Ownership of an Item can be proven by controlling the account that owns a given Item. Every Item also belongs to one and only one Group, which dictates the different kinds of behaviors the Item can perform.
Behavior Rules
Items follow the behavior rules set by their respective groups. For example, if an Item belongs to a group whose transfer
behavior is set to false, then the Item is not transferrable. If the group manager were to activate transferability with the toggle()
action, the Item would become transferrable. See the Behaviors section for more information on behaviors.
