Concepts

Background, not instructions. These pages explain the model nfty is built on, so the app and the command line behave the way you expect. Read the first two before anything else; the rest when a question comes up.

Page	Answers
The vocabulary	What a CookBook, Recipe, Ingredient, Variant, Set, Kitchen, Menu and Ticket are, and how they nest.

How uniqueness is decided	What an asset's DNA is made of, and why the unique DNA figure is a count, not an estimate.
Rarity and weights	How weights, optional layers and rules turn into the percentages a buyer sees.
Why a seed reproduces a collection	What is guaranteed to repeat, and the edits that change a collection.
Depth: paper, front and back	How a flat picture becomes a 3D model, and why a soft edge cannot.
Why nfty never resizes your art	The canvas rule, and why a wrong-sized picture is refused.
What sealing does and does not do	The real encryption, and the limits of a view-only mark.
