Wow- treating a hash function as if it’s random is standard in cryptography. We always knew that it is not 100% theoretically justified and there were works (also by me) with contrived counter examples. This is the first time there is an attack on a standard protocol that’s

Really nice work. I've suspected for a while that a result like this would hold but I'd never been able to show it. Congrats to Dmitry, Ron and Lev! I imagine a natural direction now is to see if this attack can be extended to other argument systems?
