Hi, thank you so much for this great video. Do you still remember how much resources this project used? I am trying to port your code to tang nano 9k which has only 8600 luts. I am a little bit worry it is not enough for it.

How much time did it take to break even the initial cost of the FPGA? Is it a good idea to mine using an FPGA? (I am a hardware engineer too) by mining i mean any coin, not just bitcoin.

Hi Richard. Great video and a very cool project. I want to try your design on another board and I was wondering in which byte order your sha256d_wrapper expects the mining data...Liitle endian or big? From what i could figure out by looking through your code it seems: MID_STATE = "big" RESIDUAL_DATA ="little" TARGET = "big" Am I right? Thanks for your work and the excellent explanation.

@waldemarleise7201 2 жыл бұрын

Could finally verify your design by using sha256d_fpga_sim.py to construct the necessary data. Thx a lot. The Xilinx Spartan-7 chip i am using only supports 12,5 MH/s.

I like the way the stack is displayed. This can be a nice tool for reverse engineering by tracking program execution and buffer overflow in stack. And it will be perfect if also added memory representation to track heap mangement and overflow and heap and stack collision.

I really like this project, and want to try something similar. Since the vid, have you thought about other algoritms like ETC, ERG, FLUX? If your board does 40 MH/s on BTC SHA256, I think that would bee sufficient for algos like ETC, RVN, and more. Looking fwd to more vids! Thank you!

This really reminds me of stationary points in an iterated map: the idea is if you have a mapping f acting on a stationary point N times, then output will just be the stationary point regardless of how large you make N.

Your "Ps" sound too loud, and I think there is a software making the audio quieter when you say a "P", i guess in an effort to make it less prominent, but it also drags the rest of the audio down, which is not ideal, at least for me. I can also hear some clicks but that's not as bothering as the "Ps". PD: Really interesting video!

Could a different notion of ‘distance’ (taxicab, etc) used in the Gaussian potentially yield a different lattice type?

@matthewpoynter7906 2 жыл бұрын

Love it! In the original paper, the σ value had a very strong impact on the shape of the resulting lattice. How does your explanation account for this? Does this boil down to the SOM or is it again a property of the data?

@richardharris1224 2 жыл бұрын

Great question! I've noticed that with larger sigmas, there is a single, main star shape in the center of the SOM, while with smaller sigmas, there are more broken and disjointed star patterns. But the patterns themselves have the same features for both large and small sigma (a star with 6 lines). I think this makes sense because when sigma is smaller, the learning region is smaller, so the patterns are more localized rather than global across the whole SOM. So while I did not cover this in the video, I believe my explanation still makes sense for different sigmas because the patterns are the same, just more localized for smaller sigma.

@msq7041 2 жыл бұрын

Couldnt you explain a lot of the SOMs properties by considering a kind of "surface tension" to be present, within a system where particles on average repel each other, due to being forced into too few dimensions?

@richardharris1224 2 жыл бұрын

That might be one way of thinking about it. The winning nodes in the SOM tend to move away from each other

@msq7041 2 жыл бұрын

@@richardharris1224 one way of testing this might be to feed a som with one dimensional data and see what happens; or to try and see how higher dimensional inputs affect the winning nodes...
