NOTE: No binaries are posted at this point. You'll need to build from source from my GitHub repository during these early stages of development. Windows client build is still problematic, as the scrypt-jane library does not compile cleanly with mingw.

I was doing some digging, and saw that there were commits to scrypt-jane a couple weeks ago labelled as "fixes so it will compile and run under mingw" - if you pulled that, could we get updated Windows binaries and get them posted?

https://github.com/floodyberry/scrypt-jane

Only one way to find out! I will add the changes to my repo and you (or someone with Windows) can test from there - if everything looks good I will send a pull request to WM to request that it's added.

Suggestion for official Yacoin currency symbol Ɏ or U+024E

Symbol: Ɏ
Unicode name: Latin Capital Letter Y with stroke
Code: U+024E

great idea, i like this!

It's really cool to see a live altcoin build brick by brick. :-)

I think it's very important to see YAC on sites like http://www.coinchoose.com/

I found this post with formula for BTC : https://bitcointalksearch.org/topic/m.743237

But i have no idea how we can integrate N in this formula.. someone have an idea ?

YAC was on CoinChoose for a bit, but I think sal002 took it off because it skewed the graphs. Perhaps there's another way we could have it added (on a separate "CPU Coin" section...or not have a line for it on the graph, but have it in the grid, etc).

I do agree that it's very important to have it on CoinChoose, but as it is a CPU coin with a low value, the result may not be that impressive anyhow.

The challenge is to find a way to calculate the income functions of hardware ... it is very important for someone who decides to invest in mining .. but the change in N makes it very difficult ..

Anyone willing to create logos that reflect the symbol, please feel free! Sometimes the perfect graphic isn't self evident till it's seen. I'll try myself too when I can.

Note that scrypt-jane isn't a hashing algorithm, it's a generic scrypt library that supports many different variations of scrypt, including scrypt+salsa20/8 as used by Litecoin. I've noticed quite a few people refer to the scrypt variant used by YAC as "scrypt-jane", but that's actually wrong.

So what's the name for it? Roll Eyes

We shall give it a name, scrypt-chacha?

That's probably the closest option at this point. In that scenario, scrypt-salsa would accurately refer to the algorithm used by Litecoin, and scrypt-chacha would accurately refer to the algorithm used by YAC. It's not perfect, as it describes the choice of mixing algorithm but not the choice of hash. But until someone does something strange like create an altcoin that uses chacha20/8 combined with SHA256 instead of Keccak512, I think "scrypt-chacha" is probably concise enough for now.

So, unless anyone has a different idea, let's indeed call it scrypt-chacha and correct people that call it scrypt-jane (since that's not correct regardless what we decide it should be called!).

Good one, that's another bit of originality for YAC.

I vote for this one.

I second this, it is a pretty good simple plus unicode is definetly a plus.

Sounds good. I don't think the Igorot people in the Philippines will mind. http://en.wikipedia.org/wiki/Y_with_stroke

You need a formula for the block reward, Nfactor affects only difficulty.

EDIT: from the source:

Code:

int64 GetProofOfWorkReward(unsigned int nBits)
{
    CBigNum bnSubsidyLimit = MAX_MINT_PROOF_OF_WORK;
    CBigNum bnTarget;
    bnTarget.SetCompact(nBits);
    CBigNum bnTargetLimit = bnProofOfWorkLimit;
    bnTargetLimit.SetCompact(bnTargetLimit.GetCompact());

    // ppcoin: subsidy is cut in half every 64x multiply of difficulty
    // A reasonably continuous curve is used to avoid shock to market
    // (nSubsidyLimit / nSubsidy) ** 6 == bnProofOfWorkLimit / bnTarget
    //
    // Human readable form:
    //
    // nSubsidy = 100 / (diff ^ 1/6)
    CBigNum bnLowerBound = CENT;
    CBigNum bnUpperBound = bnSubsidyLimit;
    while (bnLowerBound + CENT <= bnUpperBound)
    {
        CBigNum bnMidValue = (bnLowerBound + bnUpperBound) / 2;
        if (fDebug && GetBoolArg("-printcreation"))
            printf("GetProofOfWorkReward() : lower=%"PRI64d" upper=%"PRI64d" mid=%"PRI64d"\n", bnLowerBound.getuint64(), bnUpperBound.getuint64(), bnMidValue.getuint64());
        if (bnMidValue * bnMidValue * bnMidValue * bnMidValue * bnMidValue * bnMidValue * bnTargetLimit > bnSubsidyLimit * bnSubsidyLimit * bnSubsidyLimit * bnSubsidyLimit * bnSubsidyLimit * bnSubsidyLimit * bnTarget)
            bnUpperBound = bnMidValue;
        else
            bnLowerBound = bnMidValue;
    }

    int64 nSubsidy = bnUpperBound.getuint64();
    nSubsidy = (nSubsidy / CENT) * CENT;
    if (fDebug && GetBoolArg("-printcreation"))
        printf("GetProofOfWorkReward() : create=%s nBits=0x%08x nSubsidy=%"PRI64d"\n", FormatMoney(nSubsidy).c_str(), nBits, nSubsidy);

    return min(nSubsidy, MAX_MINT_PROOF_OF_WORK);
}

I've noticed a huge increase in network hashrate. It is now 600x my own hashrate, while it was still 300x two days ago.

The client sometimes reports garbage, take a look at these graphs, they're averaged over 144 blocks (10 blocks for 24h graphs).
Network hashrate actually decreased on the 29th due to the Nfactor change.

Hmm someone should put a bounty up for proper software or better yet integration into cgminer (which is much more likely than BFGminer due to lukejr's view on alt coins)
I'd be willing to throw a couple coins in to get a bounty up. (by coins I mean both YAC and BTC)

AMD's next gen APU with HSA will be very interesting, the unified memory addressing can be the boost for the scrypt or even scrypt jane. In next year, we can try Kaveri.
