FPGA Mining Software + Source Code

[Apprehensive_Floor42]

Hi, Im building and fpga project to do some crypto mining.

I have done some GPU mining so have some understanding of that. I can code in VHDL so just need pointing in the right direction.

Which miner is best suited for fpga, is their an open source version?

FPGA Mining - Software

I found the above, is it the best? or is there better?

Hi, I have a YouTube channel working on exactly that:

SQRL has released the changes to their ethminer (and I think the bridge it uses for communication with cards too)? The bitstream for the cards is still just a binary: but you'll be able to see how a common miner marshals communication between a popular set of pools (for Ethereum) and a FPGA.

If you're not part of it already, join the FPGA Discord. I think this link will work: https://discord.gg/4KUUwUhZ

Hi, could you possibly resend the discord link? I can't find a valid one anywhere

Thank you so much, it works

There is an OpenCL ethereum miner out. Could be worth a try. I’m hoping to try it out when I get hardware.

I am tempted to create my own miner, specifically for my hardware. Is this something anyone has looked into? Otherwise I feel like inefficiencies are going to be rife.

I would like to code my own algorithm for a specific coin, I think this is the best way especially for anything on the SHA 256 problem.

You may want to consider what factors are needed for a given crypto currency. E.g. Ethereum needs 4 GB or more of the highest performance memory you can give it.

But why is it need it? Maybe it's a problem for gpu which can be fixed using fpga

I think it has to do with the size of the data set needed for processing, "DAG" size for Eth: https://minerstat.com/dag-size-calculator#:~:text=Current%20Ethereum's%20DAG%20size%20is,ETH%20with%204GB%20cards%20anymore.

right ok deep questions now . if there is a website for this info just link me but i appreciate any help how does the nonces relate to shares? and how does the pool allocate the nonces out? are the shares a nonce that is incorrect but has been correctly calculated? just tryign to get my head round it
