A year on, and the N change approach it started seems to be catching on in face of scrypt ASIC.
For me though, the most interesting thing about YACoin is the reward scheme. With most coins, the block rewards just keep going down. For many coins released in the past few months, their POW reward go way down even in the first year.
For YACoin, the block reward now is actually higher than a year ago when it launched. Instead of starting the reward at its peak and then keep going down, the reward scheme has a bit of a fat middle part because reward increases with lower hashrate and every N change reduces hashrate/hardware. Quite an opposite of the "fastmine" in vogue these days.
