I use pooled merged mining currently. Will the BFL ASIC's be able to also mine namecoins, or just the bitcoins? Maybe my gpu's can stick on merged mining, but mainly be there to get namecoins if those ASICs can't mine namecoins.
BFL asics should be able to merge mine. You could mine litecoins with GPUs.
Well, GPU's are very programmable. The ASICs not so much. From what I have been reading, if the hash algorithm for bitcoins changes any bit by say a potential shift to SHA-3 (especially when SHA-2 gets compromised) the ASICs are then worthless. I have no clue if all these other coincurriences (namecoin in this case) uses the same hash algorithm as bitcoins. If it is the same, it should then be able to merge mine or mine other coins so long as the software is there to support it right?
