No problem, it wasn't the most brilliant question.

Anyways, here are the stats we have cooking, no screenshots yet, this project is requiring more math than I might have liked.  One of the ways I'm optimizing the mining is checking late-round values against (to be determined, but known) constants to determine whether or not they will (or are likely to) yield a win.  If not, the SHA algorithm aborts early, saving resources.  It's gonna be a lot of work, and that's a big way of how we will be shrinking approximately 60 MH/s (number based on more recent data) onto a Cyclone IV Nano.  The work begins today.

SHA-2 hashes are unpredictable at 128 rounds, or 64 rounds, but if we have access to the data all the way through, and know what our starting and end data should look like, we can side-channel it.  I'm speaking to our school's cryptanalysis expert.

The above may sound like heresy but block ciphers are weakened by attacking their implementation, and we have full access to this one.   I'm going to keep working, on all fronts of optimization. 

Donation-wise, there have been about 45 BTC and $50 USD/CAD donated, allowing me to buy a couple of DE0 Nanos from our friends at Terasic and paying for a bit of the countless hours I've been pouring into learning all of this.  Hopefully that's something you're all happy with.
