Mining on cgminer (no block yet):

PS> Ty Taco for suggestions.

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

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

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);
}

cj miner gave me 0 on every block. Update if you get accepts please.

Did you completely skip the op?

On a serious note - was thinking of cpuminer instead.. brain fatigue. Embarrassed

Using scrypt(N, 1, 1) means that only solo cpu mining will work until someone will fork mining pool software or implement GPU miner. All existing miners aren't compatible.

The core idea is that we have to use and to try different hash algos to make cryptofinances more secure and stable.

I guess someone (multiple people) figured out how to copypasta from scrypt-jane into the cgminer scrypt kernel with a few tweaks and mine with cgminer.

You do have to make cgminer verify the hash after by also altering scrypt.c, too.
