We’re at that point where the rubber meets the road. Pawel, what we had ultimately wanted to talk about was your experience with temporal logic of actions, TLA+: what drove you to use it, what your experience was, and then talk about that experience in the context of what we ultimately want to deliver with the behavioral type system for Rholang.
Pawel: Let me tell you my story, which has been a fun experience with formal methods. I had absolutely no idea what formal methods were a year ago. I’ve been using them for some dependent type languages, but the term itself was completely new to me. Then I stumbled upon a presentation at one of the conferences in London two years ago. That presentation was prepared by Kathleen Fisher. She was talking about this program called HACMS. This was a DARPA program where they performed research on whether formal methods can eliminate an ...
