Many zkVMs are implemented in Rust, using the Plonky3 library to describe their circuits. While Rust is efficient and expressive for describing complex circuits, it is a complex language when it comes to formal verification. We present here a way to pretty-print the list of constraints generated by a Plonky3 program. That way, we will be able to import the constraints in a formal verification system like Rocq to make sure they are safe and correct.
