especially if called function is intellectual property or patent-protected

If an entity such as a mathematician comes up with a new way to solve a problem — which is extensive such as a machine-learning technique — the solution-function can be rented-out as a contract or micro-business on-chain. The solver doesn’t need to know anything — similar to renting a calculator. Similar to open source but this time the creator of the computing-function gets paid “Passive income” per calculation for her brilliance.

Would like to see this written up including a description of how it would work in a realistic business scenario; namely, the callee (solution provider) charges the caller (customer) a fee for the service of calcuation the quadratic solution.

Then since the solution is ephemeral to the customer, it'd be interesting to see it written into a transaction output which has zero satoshis (ZSO).

Why ZSO? 2 reasons

1. The callee solution provider is getting paid by the caller customer, so there's no need to send back satoshis along with the solution.

2. The solution is itself ephemeral but useful to the caller's contract as an input? so there'd be no need to keep it once the caller customer uses it for it's own purpose. Thus there's no need for it to be SAT-ful.

But perhaps this is stretching it? Perhaps the solution is just payload to a transaction which includes the mining fee, thus doesn't really need to be zero-sat.
