No, there is no cryptocurrency using Cuckoo Cycle as proof of work.
Btw, in absolute performance, it runs much better on GPUs than on CPUs.
But I don't know which is better in terms of performance per watt.
Thanks, I've been reading a bit more about it. I've been away for a while - did I miss anything in the CPU space? What do you think is the most GPU resistant PoW around now?
I've come to realize it's really really hard to resist GPUs. For portability across different CPU architectures,
I haven't seen anything more resistant than Cuckoo Cycle. If you're willing to target recent x86 exclusively,
then you can increase resistance by employing the AES-NI instruction. Replacing the underlying siphash in Cuckoo Cycle by an AES-NI based hash function would likely render it much more GPU resistant. But I don't like the idea of excluding vast markets of potential hashing power (like smartphones while charging overnight).
Slowly ramping up coin distribution does seem fairer, but then a coin loses the 'goldrush' feeling that is so helpful in gaining momentum and early user adoption.
That's not so much user adoption as miner adoption, and does little to the long term staying power...
