Nova: You have blatantly misunderstood how hash functions work, and specifically how scrypt works. I agree with WindMaster, there is no way you have made, or will make a scrypt FPGA. I advise everyone to not send Nova money.
Ok, elaborate. Please explain in laymans terms how a cryptographic hash function in general works first. Then also explain in laymans terms how scrypt differs from the SHA-256 of bitcoin.
If I have completely misunderstood hashing over a lifetime of programming, then I really have some long hard thinking to do.
My guess is that you're focusing on an over simplified explanation, something I can present to people who may or may not have any sort of experience with programming or hardware dev and assuming that the reductions and omissions are there as an oversight or misunderstanding rather than the fact that they are not relevant to what I'm attempting to explain and thus intentionally omitted.
mtrlt, please enlighten us.
While doing so, don't try to point at the flaws in my explanation and say "it's not x but y & z". Instead start from scratch. Try to remember your audience here.
Frankly I'm genuinely interested in this. I'm also impressed with all these FPGA experts chiming in with their knowledge, looks like lots of people have fully working LTC FPGAs.
As for everyone else, the offer is still open here.
If anyone has sent me money and decided that they no longer feel comfortable with the idea of what I've stated before they can request a refund.
Also mtrlt is half right, I have not made a fully functional FPGA for LTC yet, it's sort of why I'm asking for help to raise funds to buy the bits I need.
Some good news is that people have been suggesting alternatives to build this on which could end up being much cheaper. I'm currently swimming in whitepapers
Anyways, I'm with mtrlt & windmaster on this. I expressly advise against anyone sending me money unless they understand that what they are getting is the collective result of what I learn in this process. While the goal is to produce an FPGA with a version of scrypt with a slower section optimized away, this effort may not produce a result other than "oh ok, so it didn't work because I was wrong about x". If I had all the information I needed or I had the money to purchase the equipment to check it out, I wouldn't be going this route.
I am learning a lot though. There do appear to be candidate boards that may work. I'm studying them carefully now.
