@real_or_random @claudiorlandi Let me add that in principle, the RO could be instantiated with a trusted party that answers to queries. Agreed is useless in practice, but theoretically it does implement an oracle, and if your proof relies on using its code, simply cannot be instantiated.

@real_or_random @claudiorlandi The point is there is no poly-size *circuit* that can implement the RO. I can't pinpoint a reference for this; https://t.co/0lfbcbhOOf shows that if the RO is implemented with a function that is *fully specified* to the adversary,the RO methodology fails.
