There will be many types of digital assets that can be issued on Tari. The aim of this Request for Comment (RFC) is to help potential asset issuers identify use cases for Tari that lead to the design of new types of digital assets that may or may not exist in their ecosystems today.
Tari digital assets may exist on the Tari Digital Assets Network (DAN), are perceived to have value and can be owned, with the associated digital data being classified as intangible, personal property.
Digital assets may have the following high-level classification scheme:
- Event-driven or historical, e.g. a rivalry or a highly temporal event
- Artefacts or objects
- High demand
- In-game items
- Full or fractional representation
- Bearer instruments/access token
- Chat stickers
- Personality trait(s)
Digital asset tokens may influence the following behavioural types:
- Advance purchase
- Experience enhancement
- Reward for performance
- Donating to a charity
Digital assets have many different properties, which may be one or more of the following:
- Digital assets can be interactive:
- Easter eggs;
- dynamic, e.g. imagine if assets were similar to sounds, visualizations or other kinds of "demos" or "gifs")
- Game mechanics;
- Easter eggs;
- Digital assets can be combined to create super assets.
- Digital assets can be attribute(s) of another digital asset, e.g. wheels of a vehicle or a VIP ticket has two drink cards.
- Digital assets can have contingencies, e.g. ownership of a digital asset is contingent on ownership of a different digital asset. Using this digital asset is contingent on holding it for a particular duration, etc.
- Digital assets can have utility, e.g. be useful.
- Digital assets can be used across platforms, e.g. a digital asset for a game could be used as avatars in a social network.
- Digital assets can have history.
- Digital assets can have user-generated tags and/or metadata.
Digital asset owners may have the following interactions with the DAN and/or other people:
- Digital asset owners can attest that they have ownership over their assets at time
- Digital asset owners may attest ownership to an individual, to a group of friends or to the entire world.
Rules are the governance of how digital assets may be used or transferred, as defined by the asset issuer:
- Royalty fees. Digital asset issuers can set a royalty that charges a fee every time the digital asset is transferred between parties. The fee as defined by the issuer can be fixed or dynamic, or follow a complex formula, and value is granted to the issuer(s) and/or other entities.
- Contingency. Digital asset ownership/interaction may be contingent/dependent on another asset.
- Timing controls. Digital assets can only be transferred or used at particular times.
- Sharing. Digital assets can be shared with others or even co-owned.
- Privacy. Ownership of a digital asset can be changed from private to public.
- Upgradability/versioning. Digital assets can be upgraded and/or versioned.
- Redeemability. Digital assets can be used once or multiple times.
Some examples of how different types of digital assets with different attributes, rules and interactions may be manifested are provided here:
- Is rare, it is 1 of 5.
- Is legendary:
- press reports that this artefact could be worth $X.
- Drives collectability.
- Drives advance purchase, e.g. if you are one of the first 100,000 people to buy tickets to Indiana Jones World, you have a chance of winning this 1 of 5 artefact.
- Has superpowers and utility, e.g. if you have this item while visiting Indiana Jones World, you get to skip the line three times.
- Is a contingency for another asset, e.g. if you collect this item, two Sankara stones and the Cross of Coronado, you
can buy the ark of the covenant:
- Ark of the covenant is rare. It is 1 of 1.
- Ark of the covenant is legendary.
- Ark of the covenant gives you lifetime access to Indiana Jones World.
- Ark of the covenant has rules; 20% of the resale price goes to Indiana Jones World.
- Is not rare, it is 1 of 100,000.
- Is legendary - https://www.youtube.com/watch?v=HK6B2da3DPA.
- Drives collectability, it is part of a series of bats from famous batsmen.
- Can be combined with other assets, e.g. be one of the first 10 people to combine six bats to turn this asset into a
One Day International (ODI) century bat:
- ODI century bats are rare, they are 1 of 10;
- ODI century bats are legendary.
- Has no superpowers.
- Has no utility.
- Has no rules.
- Is rare, it is 1 of 200.
- Is legendary:
- Has a game mechanic:
- Every time it’s transferred, it may become a golden ticket that grants you access to any Drake show.
- If it becomes a golden ticket and is transferred, it loses its golden ticket superpower.
- Has utility:
- Unlocks exclusive media content feat. Drake hosted by OVO SOUND.
- May become a golden ticket that grants you access to any Drake show.
- Has rules - every time its transferred Supreme and OVO SOUND receive 25% of the transaction value.
