@ -5,6 +5,36 @@ so it would be 2^12 for this one. or for (~uint256(0) >> 16) it would be 2^(32 -
so really for every algo you simple need the bitshift on a zero value uint256.
I believe these are the true diff1 values that should be used on pools for each algo

Maxcoin devs, it seems, did not simply implement keccek in the way that litecoin devs implemented scrypt.
Or how the darkcoin devs implements x11, or how the quarkcoin devs implemented quark. The maxcoin devs
decided to change several parts of how the the currency works - so that instead of simply changing the block
hashing from sha256d to keccak, you have to change a few other parts of the block creation/submission progress.
I believe there is actually at least one coin that implemented keccak hashing normally - copperlark coin.
Too bad its source and binaries are only on some sketchy russian site and neither will compile/run on my
system.. Anyway, it looks like several coin devs forked this maxcoin and switched out keccak with
a different algo. This group of max-tainted algos I believe to be: keccak, fugue, blake.
There may be more, and there may be coins that implemented those algos the regular way instead of the maxcoin
way. So.. for each of these max-tainted algos we may have to implement, for example, blake and blake-max.
