The office space indeed looks a bit dodgy but of course this is the "bricks and mortar" portion in the UK...I cant really blame Alpha for not spending a ton of overhead in a high end area to properly register.
The most critical aspect of the development is the technology which is obviously in India. Dexcel certainly appears legit. As already mentioned in this thread, I think it's important to carefully consider the DATA that Alpha and Dexcel have produced to date, two parts in particular 1) proof of concept publication and 2) prototype video.
I am not capable of peer-reviewing Dexcel's concept paper, "Implementation and Analysis of Scrypt Algorithm in FPGA (Proof of concept)" (link below) but for those who have read and understand it, is the physics, math and code feasible? And as for the video, I did not quite understand what the dude was showing on the screenshot. Is anyone familiar enough with hardware to comment on the board and setup?
I guess what I'm getting at is can anyone explain or comment on the feasibility of these two bits of data?
