Hey! Yeah that was a project I put together for the impervious hackathon. It's still unclear if it's really a good idea to use lightning to move data back and forth like this does. In reality I'd love to find a way to do the same thing but just use lightning for pay-per-execution. I think you can pretty much do this type of thing with LSATs but would still be nice to build a little framework around it. I'd also love to find a way to enable 'trustless' code execution where you can pay someone to run the function for you but have proof they didn't modify the code that is run. I think there's a way to do this as some future extension of ideas used in DLCs.
