i don't mean to piss in the pool but with AI GPUs on the verge of peak supply and the market commoditising there is a serious problem that any hash function can be run by inordinate amounts of compute power. novel hash function is meaningless when you can implement it in cuda or opencl in a day. the hash function is not spamcoin's vulnerability. it's its difficulty adjustment and hashpower. draw enough sha256 asics off spamcoin and they are the ones with 5 hour blocks.
