I have heard that Spondoolies is testing their miners in pools right now. I have also heard buzzing about the fact that they are not yielding as many solved shares as should be theoretically possible. Could this be because of a hardware bug in their chips?
Source?
It is requires special logic in ASIC to withhold winning blocks in HW while keeping the non winning blocks.
It is relatively easy to withhold winning blocks on any miner in SW.
We are open source miner. We compile official Con's cgminer from his repository in our official image. Of course, anyone can compile block-withholding SW for our miners, but the official image that we release and test does not do it.
