The Hard Problem With the Knot-Based Bond Money Scheme
We believe we can use such a framework that generalizes the knot-based money scheme into something we call invariant framework. In this framework, basically, we have these sets of elements that can be divided into equivalence classes. And within each equivalence class, there is a permutation. There is always a path of operations that you can operate a sequence of actions on one element that allows you to permute to the other Element. We bring up these very generic assumptions called harness of class fighting and knowledge of path assumption. Based on these two assumptions, we are able to prove our upper-money secure. So, actually, quantum-lightness is just a strengthened version of quantum-
