im going to be the skeptic; don't take it the wrong way.
Why arent you doing this? :
The expected production process is as follows:
(2) Gather enough pre-orders to be viable - aim over next 1-2 weeks.
(1) Give out full details of product and offer.
(3) Payment for pre-order/ hard commit by customers.
(4) First production boards get delivered approximately 8-10 weeks after stage (2)/(3). We will try to better this but this number determined by our parts suppliers.
Things such as currently working bitstreams, guarantee of algos that will be available by what date (specifically) as well as hash to power figures....
As of this point; in this day and age; you
should have at least a physical demo and review of the hardware verified by a heavily trusted member before taking in any funding.... as in the past; taking in funds before us seeing some actual results on this website from a trusted reviewer, has almost always resulted in disaster of many different levels and proportions.
At first glance, I see a big up front hardware cost; with no promise of return other than a stated interest in algos (no word on active development or working hashing bitstreams for instance...); especially since you mention algos that are constantly changing to be as asic/FPGA resistant as possible... we aren't not even any sort of efficiency datum or anything; just a spec sheet for a publicly sourceable fpga.
The hardware looks like it should be very versatile; and it looks like the product as shown is a sound concept/design.. but; you are asking a bunch of people to jump off a cliff right now without knowing if there's a parachute attached to their back while boarding the plane.
I hope you understand my concern, and its meant in the best of light to help you succeed. These are the main red flags I have to share and ask about.
