Suppose you want to start a hedge fund like Numerai. You want to issue a token that can only be held or traded by data scientists, whose models you want to collect and evaluate.

You first solicit applications from data scientists through your website and decide whether they’re worthy to participate. The candidates you’d like to enroll send you their Ardor addresses, and you use your account to mark their accounts with a special property indicating that they are eligible to participate. Next, you issue an asset on Ignis using the new Asset Control and Vote by Account Property features, and specify that your asset can only be traded by accounts with the property you used to designate eligibility. You then make payments of your asset to each account proportional to how well the account holder’s models perform, and you pay dividends to all asset holders in proportion to their holdings. The result is that people who submit the best models get the biggest shares of your dividends.

Perhaps you charge your users a fixed quantity of your asset for each model they submit, both to ensure they have some skin in the game and to help redistribute the asset away from the users who submit the worst models. Since Ignis supports sending short messages along with payments, a user could annotate such a payment with an ID number that corresponds to the submitted model, allowing you to easily track which models’ submission fees have been paid.

Note: This can be done right now on the Ignis blockchain using the standard Ardor wallet. Or you can write an app with a custom interface that interacts with Ignis on the backend and your users won't even know that they’re transacting on a blockchain.
