Title: FPGA/GPU optimized but ASIC proof SHA256 coin? Is it possible? Post by: TheSwede75 on June 13, 2013, 02:55:30 PM Completely hypothetical question. Would it be possible/feasible to design a coin that uses SHA256 but with variables that are explicitly ASIC hostile (memory requirement, cycles or other factor) towards the current BFl/Avalon architecture and optimized for current gen GPU/FPGA?
I think it's if nothing else a fun proposition. Title: Re: FPGA/GPU optimized but ASIC proof SHA256 coin? Is it possible? Post by: markm on June 13, 2013, 02:59:06 PM Sure, just do sha256(sha256(sha256))) instead of sha256(sha256)

This is interesting, both from a hardware perspective as well as programming/software. I'm almost tempted to get something running on testnet and analyze performance differences. |
