I posted this idea on Bitcoin Talk so I thought I should at least seed the project here on the forum.

Once we have established that we can change the hashing algorythm to NeoScrypt, there is no reason why Feathercoin can't change the algorithm again. There is already the possibility that Feathercoin could remain with consumer equipment mining (ie GPU), such that if an ASIC is developed for NeoScrypt - we could change the algorithm.

Obviously, it would be not be good idea if Feathercoin were the largest hasher of NeoScript, by an order of magnitude. However, what if Dogecoin changes their mind on Litecoin takeover and goes NeoScript, or another meme coin becomes mad popular with NeoScript, or no one can ever develop a NeoScrypt ASIC?

However, it is also possible to do things the other way round, that is develop an ASIC and then change the Algorythm such that only that ASIC ( or general GPU) will work with Feathercoin, thus removing the main downside, coin swapping by big coins taking over the network.

My original idea was to hardware modify Scrypt ASIC miner with a special chip. It could just be a code chip. We would use a modified Scrypt algorithm + the decoder. Other coins could use the same principle to have their own ASIC, they would just develop their own "coder chip" and implement the modified scrypt.

Basically, ASICs are cheap, efficient, quiet and don't use gallons of electric. They are essential for a serious coin, but each coin does need their own ASIC to prevent 51%. Adding a hardware differentiator would make it hard to coin swap and takeover other coin networks.
