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 remember Anonymint saying he had a secret CPU PoW years ago - has he said any more?
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.
