There's one problem that I've been trying to find solutions for, but I think it's just way out of my depth. So for example if I'd created farming kits with built-in sensors that measure everything from soil acidity, moisture, crop height sensor, etc for distributed research via blockchain data "rental". How do I even begin to be able to trust that I'm paying for real data? Someone could just fake any signals, unless there's a way to pair signals with hardware and time of transmission. Not even sure what word I'm looking for to describe this problem.
