I just wanted to through this idea out there, sorry if this thread is considered dead or not it has been quite a few days. I was kind of curious if it would be possible to implement an FPGA as a sort of hardware wallet that could be interfaced with an Ethernet adapter (say for arduino). Just kind of a thought I guess, some sort of stand alone, networked FPGA system that would hold onto your bitcoins and not rely on the computer (which can be more easily breached). I guess I'm thinking of something like a piggy bank for bit coins.
