what i cant understand is this code taken from https://github.com/zcoinofficial/zcoin/blob/master/src/main.h#L1356:

You see that "if TestNet" hashing is LYRA2, else it is scrypt_N_1_1_256

so are we mining scrypt_N ? Huh

Code:

uint256 GetPoWHash(int height) const
{
uint256 thash;

if( !fTestNet && height >= 500){
LYRA2(BEGIN(thash), 32, BEGIN(nVersion), 80, BEGIN(nVersion), 80, 2, height, 256);
}else if(fTestNet && height >= 138){
LYRA2(BEGIN(thash), 32, BEGIN(nVersion), 80, BEGIN(nVersion), 80, 2, height, 256);
}else{
scrypt_N_1_1_256(BEGIN(nVersion), BEGIN(thash), GetNfactor(nTime));
}

return thash;
}

Are you seeing straight? Look at these lines:

if( !fTestNet && height >= 500){
LYRA2(BEGIN(thash) ...

For those of us who aren't technically versed in programming: it basically means "if the miner isn't in working in TestNet AND height is above or equal to 500, then use Lyra2". Hashing algo was switched in order to improve the resilience against GPU/ASIC mining.

OPS, i just noticed the "!" which means "not" Grin
