Writing just to present additional KRB mining pool at
http://krb.sberex.com/Decided to launch new one for a couple of reasons:
1) Im not quite satisfied with existing KRB pools as for GPU mining encountered an issue of work in idle when pool doubles complexity each step. By try and error I think I resolved the issue.
2) It is often when one pool has more than 51% capacity of the network which may potentially lead to 51% attack. So more decentralization is needed.
3) Making a pool is really interesting thing!
Thats it!
