In the last few months, I've been working on something that, quite frankly, I have struggled to name. At first glance, it feels like a rollup—a validity rollup, to be precise. But then again, it also feels like an oracle. Sometimes, it even starts to resemble a zk coprocessor or some strange hybrid between them all. In truth, what we are building may not fit neatly into any one of these categories, and that's precisely why I want to talk about it.
