From the spec:
> The large botnet is a serious operation with many thousands of computers organized to do this attack. Assuming 100k medium-range computers, we are talking about an attacker with total access to 200 THz of CPU and 200 TB of RAM. The upfront cost for this attacker is about $36k.
They appear to define it by compute capacity, so I'd expect the attacker can solve harder puzzles than legitimate users would attempt.
