Hello!
There is a new coin named Copperlark (
https://copperlark.com/en) - with SHA3 algorithm.
One developer wrote a pool client for this coin, however there are some questions remained.
The pool client is working so far and gives a possibility to mine on the graphic cards. However the hashrate lies below the expected values of many hundreds of MH/s (like for e.g. bitcoin). The typical 7970 speed does not exceed 25-30 MH/s. So there is some code optimization needed. If someone feels like he can look on the present algorithm and suggest new ideas (as proposals or as a source code) please contact me.
Thanks!
