Hi Guys,

I'm relatively new to bitcoin, but not to FPGAs. After developing a few things in VHDL I thought it might be fun to do our own bitstream, so who is in? I don't know if we get it better than the ztex one but since it doesn't use any enhanced stuff like DSPs or blockrams there might be some space for improvements besides, I think it is good to have a second choice, because diversity is always good.

So, who is in?
Transactions can optionally carry transaction fees. Whoever mines the block which ends up containing your transaction will get the fee. The Bitcoin client will sometimes force you to pay a fee when it thinks that no miner will accept your transaction otherwise.

well, thanks, but its not that hard, we only need a very lightweight sha256 implementation. the algorithm itself isn't very hard to understand, but making it light and smooth will take some work Smiley and when we have that we basically need to add a little bitcoin stuff, if I understood it completely that is just a small thing checking if our hash we found is good enough (in terms of difficulty).
when we have these two things we just need to add a UART, since basically every FPGA board supports UART and then we are done with it.
but if I had enough time to do everything myself I wouldn't ask here Smiley
