If you're referring to src/cuckatoo/mean.cpp, then the reason there's no mean32xN target in the Makefile is because that program cannot handle DEDGEBITS=32 in any way (without a major rewrite). A...

Yes, such OOPS errors are expected:-(

Separating the main functions is on the todo list. There's also a huge amount of overlap between cuckoo and cuckatoo solvers. Eventually I will try to merge those back into...

The paper claims that "All of these checks ensure that the difficulty transitions of queried blocks are valid." which to me seems incorrect, unless they check every single difficulty adjustment,...

Please hold off on rewriting hash_with_index. I'm entirely unconvinced we need that. In my last email to Benedikt I wrote: Wouldn't it suffice to check that the cumulative difficulty change...
