ThirtyBird, I don't understand.

18 Jan transaction:

c0da477d4db7c4f82342a3f65e0c6bdc2d7ebfea7a220102a504ab3b4e156ad5

7 Mar transaction:

The question mark still shows on the left side of the qt. It SUBTRACTED the coins for stake right? Well I currently have 0.00 coins in my wallet under 'Stake'. It is as if the coins were supposed to be sent to stake but actually just disappeared.

It isn't happening for every stake. This error has happened only 3 times this year (out of about 70-130).

You're giving transactions that do not exist.  If you have no coins in your wallet, either the coins were never staked, or were stakes successfully and you spent them (or you need to restart the client - without any valid information to look at, who knows?).  Provide the address that received the coins and a time/date they were received.

My point of posting those transactions was for you to see that they do not exist. But you saw the screenshot from my wallet. Also, POS always shows 0.00--I imagine that is because nothing is being sent to another address. When you earn coins from POS, it still shows 0.00, so that means nothing in terms of saying I gained coins or lost coins.

I honestly cannot say if those last couple transactions actually caused a decrease in total coins in my wallet. However, the first time it happened, I am pretty certain it did (I didn't have many coins in my wallet at the time. so I noticed 500 coins gone). Either way, this is STILL a big problem that I think needs to be addressed. I'm afraid the only way for me to know for certain is to lose thousands in one stake, but then you may not believe me even then.

What it shows right now is that I have 875 total coins sent to stake, but they have never come back nor are they in the block explorer as having been sent to stake at all. Whether you believe I am actually missing coins or not, that is what it SHOWS. If they were orphaned, there needs to be a way to indicate that?

Orphaned stake transactions are currently confusing that's for sure. For now, you can spot them with the question mark to the left (signifying an undefined transaction) and in the transaction details it says "Status: 0/unconfirmed". Orphaned blocks are supposed to have their transactions removed from the client wallet's transaction database. It works for orphaned POW blocks, but there is a bug in Reorganize which is making the orphaned POS block transactions hang around even after closing and reopening. When the next version of the yacoin client gets released there are changes in place to ignore orphaned POS transactions so they won't show up in the transaction list after a restart of the client. But as of now the bug will still manifest itself in the "Number of transactions:" field on the main window.

There are also changes in place to report the actual number of coins gained from your POS blocks in the transaction list, instead of reporting the number of staked coins. And a new transaction category has been added called "Stake interest" which will allow you to more easily count up how much interest you have earned. I'm sure this will stop people from thinking their wallets have lost coins, since the interest generated from a POS block is much smaller then the number of coins staked.

Just post the address.  

The address for all three is my main address YL5kf54wPPXKsXd5T18xCaNkyUsS1DgY7z.

Anyway, thanks ThirtyBird, Groko. I'm looking forward to the next release from Joe_Bauers. I'm not going to lose sleep over the 875 coins, but I would lose sleep over the potential to lose more. But I appreciate the assurance that, in reality, no coins are actually being lost and that it is just the client erroneously implying such a thing is occurring. Just imagine me trying to convince a friend to buy YAC and hold on to them for stake, then telling him not to worry about that minus 500 transaction with the '?' next to it. Sorry to sound like an armchair quarterback (not a computer programmer--which is a gross understatement), but I figured this issue, whatever is happening, was a crucial one that needed to be fixed. I beat the dead horse.

Thanks you so much.

Do those correlate the the amounts you are looking for?

Joe_Bauers & Sairon, Since the TXID is different than his client thinks it is - could Transaction Malleability be affecting POS generation within the client?

Ugh well unfortunately I'm not going to have access to my wallet until Wednesday, so I won't be able to check if those transaction are in my wallet until then. :/  I don't know off the top of my head how many other proof of stake transactions (and amounts) I had that day. But yea, that would correlate to the right amounts.

Just focusing on the 18 Jan transaction, I took a screenshot of a possible stake that eventually went through? It was approx 500 coins with that question mark. I have many 125, 250, 500 packets of coins if you will that stake regularly, so it seems impossible to tell if those very coins were indeed staked correctly at a later, or previous, point in time....

Not sure without looking into a lot further. I think it's partially the case of the horrible way the client shows pos transactions and what groko already fixed, but if the TXID is indeed different, then obviously something weird is going on.  Maybe the YbCoin folks can fix it  Cheesy

I made a lot of progress on the stake function for Qt today.  I can see why no one did it in the past, it's a real pain  Tongue but will be cool when done.

Also, forum.yacoin.org is now live. Thanks to Sahtor for doing all the work to get it going again!

That one showed up in block 388734 with the transaction id you show.  Do you know how to use the block explorer to search for these things?

I'm obviously doing a terrible job explaining things... the txid I just posted is from the transaction in blue letters (1/20/2014 01:02). You made the point that my coins are find and that I just have to find them. Well there are many candidates if you just judge by approx time (within a few days) and coin amounts. But how am I supposed to know the 1/18/2014 14:22 transaction is somehow related to the transaction i just took a screenshot of or the block explorer links you posted previously. It still looks like I just lost coins into stake oblivion if I open up the 1/18/2014 14:22 transaction.

Thanks so much Joe_Bauers. YBC qt will have nothing on YAC qt.

I know your pain Joe_Bowers. I tried totaling up up all the inputs eligible for staking in CWallet::CreateCoinStake (in wallet.cpp) then printing the result out the log each time it's called. But the total just jumps around randomly. I can't figure out if there is a bug in that function, or I just don't understand how that function goes about finding inputs that should be checked for possible POS block generation. There is supposed to be some unpredictability function so people can't game their POS blocks for some kind of timed attack. Perhaps that's whats making it tricky to understand.

I wrote a How-To for determining how many coins in your wallet are being mined for POS interest.
I show how to use Coin Control get your total number of coins being minded by the YACoin client.

You can find the How-To here:

It's great news!
Can you provide an option not to split staked coins on two parts?

Sure there is. Follow the instructions at https://github.com/yacoin/yacoin/blob/master/doc/build-msw.txt. At step 26 use Makefile.Debug instead of Makefile.Release
Code:
c:\yacoin>mingw32-make -f Makefile.Debug
c:\yacoin>cd debug
c:\yacoin\debug>copy ..\release\*.dll .
c:\yacoin\debug>gdb yacoin-qt.exe
(gdb) list CWallet::CreateCoinStake
1373        return CreateTransaction(vecSend, wtxNew, reservekey, nFeeRet, coinControl);
1374    }
1375
1376    // ppcoin: create coin stake transaction
1377    bool CWallet::CreateCoinStake(const CKeyStore& keystore, unsigned int nBits, int64 nSearchInterval, CTransaction

OK, I added the stake function to testing. I tested it over the past few days and everything looks good. Test it out if you can (you'll need to build), and if no problems, I will release it (including a windows build) soon.

if someone is still interested in my case Smiley....the coins arrived at last.

i opened the third ticket, and i was a little bit rude and sarcastic, maybe that helped, but,
agent Leah, again excalated ticket to tier 2agent, Mullick.
He said that these problematic transactions have gotten stuck in their wallet due to being to large to fit into a block (too many inputs).
he resent them and now, after two months, YACs are my wallet.

I wrote a How-To for determining how many coins in your wallet are being mined for POS interest.
I show how to use Coin Control get your total number of coins being minded by the YACoin client.

You can find the How-To here:
http://yacointalk.grokonet.com:8090/t/calculate-your-staked-coins-with-coin-control/41

I am not familiar with YAC POS calculation. I see this line here
Quote
Each chunk of eligible coins has it's interest calculated based on the chunk's age in the range between 30 and 90 days.

Does it mean for POS generation if I have 100 YACs in the wallet for 1000 days I can only expect 100 * 90* 5% / 365 reward if a POS block is found? In PPC POS calculation the probability of finding a POS block is based on coin age capped by 90 days but the reward value itself is not capped. In the above example I would expect 100 * (1000 - 30) * 1% / 365 reward.

I've got only promises from Mullick 24 days ago but nothing in my wallet..
I will open another ticket!

Groko - that is a great post on yacointalk.  I've been mining YAC since the launch, and I learned a few things from your overview.  Thanks!  Smiley

And I believe mhps is right - I think YAC caps POS at 90 days.  So a 100 YAC transaction at 1000 days would produce the same interest as at 90 days (100 * 90 / 365 * 0.05 YAC = 24.65 coin years * 0.05 YAC => 24 years * 0.05 = 1.20 YAC gained). 

Again the guide is very well written, but it maybe helpful to add an example, or two, of how the 5% interest is calculated.  Things like the coin-year rounding down to the nearest whole year weren't initiative to me when I originally started.  From the example above, I would have expected 1.23 YAC instead of 1.20 - it boggled my mind why all POS were 'rounded' to the lowest 0.05.  I figure if we can save someone an hour of sifting through the forums, it will benefit the community.
