Let's hope mtrlt either holds on to his GPU kernel like it appears he has to this point, or if released, it's released to all. Anything else risks the stability of the YaCoin network.
This is indeed my plan.
So, theoretically, what would happen to YAcoin if GPU mining was available to all right now, and suddenly came to a halt in August? What technical consequences would there be? How long would it take difficulty to readjust back to a level where CPU mining was viable?
edit: I should learn to read more.
The other risk here is a possible inadvertent "difficulty attack" if this N=8192 issue is real and a GPU miner is released to all. At that point, difficulty would increase sharply, and once N=8192 is hit, drop off a cliff. I wonder if there would be enough hash power after that to get it back to a sane level without necessitating a hard fork like feathercoin has done (maybe WindMaster has more input on this). Also, whether POS minting would be enough during that time to validate new transactions on the network. Maybe others much more knowledgeable than I on these matters could comment.
