Derived Collectibles
A digital collectible today is usually just an unchanging picture plus a transaction history that nobody actually reads or displays. That history, and the passage of time itself, carries interesting information (who held it, how long, how often it moved) that is thrown away instead of being used to change how the piece looks. This standard describes a way to make a collectible's appearance change over time and with use, computed fresh from public chain facts, instead of being fixed forever or controlled by a server.
