how much cost 1 Zcoin?
i want to buy few coins for testing, shoot me pm someone who can sell me few coins for testing at fair price

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 ? 

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;
}

        }

        return thash;
}

It was scrypt_N and i have mined with GPU initially. But there were some TITAN scrypt that raped entire hash, and after block 500 zcoin was forked to Lyra2 only CPU to prevent GPU asic.

        }

        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"

I want to repeat my question.
I tried to run the zcoin-qt.exe wallet application, but how can I generate an address with it?

Thanks!!!

Click on the 'Receive' tab and then 'New address', bottom left.

Yet it premine with hidden gpu miner, get ready ass because it will hurt

there is no gpu miner, also there is no hidden gpu miner!

are you joke? so how do you explain this hashrate?

Maybe it is a botnet or someone rented Amazon EC2.

Doubt it's EC2. Not cost effective. 32 core server was averaging 250H/s. At that rate you'd need to be running 1,200 of those instances to get 300KH/s.

Undoubtedly a botnet or private GPU miner/farm.

        }

        return thash;
}

From block 500 lyra2

So your saying, that ontop of a 10% on-going premine, The first 500blocks had been Scrypt-N to benefit GPU miners?

what do you think about poloniex and other exchanges? there will be chances to be on it?

[tomsmith26]

if this coin was listed on those exchanges . it would be a 0.015-0.02btc/xzc . i'm sure

this ANN needs to be translated into some languages to get the attention of those non-english speaking traders and investors, we have some translator here in the forum, we made translation for a bounty, if in case you need one, i can do the Filipino translation.

why not fix this shit ?

however the codebase is old and needs lots of cleaning of unused shit, and migrating to a newer codebase.

Which is price for btc with that old code from 2009? I think 630 usd right?

Any serious trader that doesn't speak english fluently should seek for a new job.

Stop those ridicolous bounty translations, no one needs them, get yourself some coins by mining like everyone else or buy some.

Cpu-pool what is happening with the hashrate ?
190 workers = 3.83 KH/s ?!
My hashrate too shows real hs / 5 ??

Trying to get the correct hashrate displayed, but it's not so easy.. It decreases with very new block it seems
