[ANN][YAC] yacoin: yet another altcoin. START is now.

[tacotime]

I hooked up an old pc turn it on put yacoin there and start mining instantly i get block found before wallet is synced with 100 yac...
WTF

It'll end up as an orphaned block. Current block-reward is less than 50 YAC (reward goes down with # of blocks in the chain, started at 100).

No, it goes down with difficulty increases, same as PPC/NVC.  It looks like it uses the same reward algo as NVC.

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);
}

PS> Ty Taco for  suggestions.

If this is working properly will you be releasing source or compiled binary? pls

[r2edu]

He´s not getting any "A", something is not working there

BTW, if you're getting HW errors it probably means that the hashes aren't being confirmed by the CPU.  Double check that you implemented the code in scrypt.c correctly and that you are using a high enough thread concurrency (set your network target to something like diff 4 then try to submit there, they will all come up as rejected by the network but you can verify you wrote the code correctly if they are).

Pretty sure he's trying to use a GPU....Not many cpu's can hash like that

I got 1 accepted but orphaned and 5 rejects.Too much to work and Im sleepy.I think Ill call it for the night.Maybe someone will figure it out till tomorrow

later edit 7 rejects already

Then it will be too late, you need to figure it out now, NOOOOWWWWW

implying he implemented anything at all

This isn't a bright start for the future of YAC GPU mining.

Trying to use CGMiner??

Up until an hour ago I was getting a lot of orphans. Now I get nothing. I miss my orphans

Still getting blocks here... looks like 7-12 per hour and a half or so on these Xeons?

[nfuse]

got about 22 blocks now with 4 pc's (600 kh/s) orphans about 160 so i am not complaining   strange thing however is that my fastest pc (amd octacore @4,6 ghz found almost no blocks at all (about 3) and my xeons doing a great job. so maybe it's an amd problem?

How many connections does each machine have?

Does the one not getting blocks also have way less connections than the others?

-MarkM-

no all have 8 connections (didn't opened the port in my firewall)

Seems like a lot! I don't have a good connections (socks proxy) but that shouldn't stop me from getting orphans. What hash does QT report for your servers? Are you talking about one or mulitple? (7-12 per hour)

I'm have trouble getting any coins, my C64 is churning out a whopping 2hash/s.

What could possibly be wrong?

Any help upgrading to an Amiga would be appreciated YAC: YCitno2EtBFMzdwKMSqokMuQkiZwH2uUny

I sent you 1 YAC so that you don't have to turn on your C64 anymore this year

Thank you greatly, I can now afford the game I was wanting (Manic Miner).
