Hello! is it possible to merge mine this together with NMC? they are on the same chainid....
Ack. 611 is not merge minable together with NMC because it shares the same (default) ChainID with NMC:
hook.h:    virtual int GetOurChainID() = 0;
Changing this setting would require a hard fork:
bool CBlock::CheckProofOfWork(int nHeight) const
{
    if (nHeight >= GetAuxPowStartBlock())
    {
       / Prevent same work from being submitted twice:
       / - this block must have our chain ID
       / - parent block must not have the same chain ID (see CAuxPow::Check)
       / - index of this chain in chain merkle tree must be pre-determined (see CAuxPow::Check)
        if (!fTestNet && nHeight != INT_MAX && GetChainID() != GetOurChainID())
            return error("CheckProofOfWork() : block does not have our chain ID");
NMC merge mining profits are near to zero. The yield mining 611 has significantly been higher since a few years.
Is this design flaw therefore a real issue to 611 miners?
