that's how bitcoin works, that's why we called it 'blockchain', previous outputs used as inputs for new transaction.

Damn I need to learn this shit more in depth  Grin Grin Grin

OK OK OK

Guys this has been fantastic. Thank you for the help!

It looks like it could have been dropped as the member above said as a double spend.
I cannot find the on any explorer either.

That transaction was one I made a while ago. I assumed it had gone through. My wallet hasn't downloaded the whole blockchain yet so it's still displaying as having left my wallet.

But if that's the case, that means the funds from that transaction are actually still in my wallet. (4ab3ecc9a14ce6a9866ee048eeef4a7ea8c726e016e6316f2a00d5973f22cbae is the ID of a transaction i made from the wallet to this address: 3MPLa3XGKGcDbSCvBdjEtXWkvXAhNGJmcJ and it hasnt confirmed. im not sure what the inputs were or how i'd find out. i don't even recall who i was sending this to or why)

I think I still don't see how that affected this new transaction though. Surely the unconfirmed transaction isn't being considered a "parent" of the new transaction? I don't see how that makes hierarchical sense...

But on the plus side... theoretically I can abandon that old transaction, and that would mean i have more coin in my wallet, and i guess i write a new transaction which would select valid inputs? (bit out of my depth here i think lol)

Nice, I was wondering where that address came from.

post your hex rawtx for above txid, that tx might have been dropped for double spend reason

ah sorry, what is a hex rawtx? isn't that what i posted already?

6  Bitcoin / Bitcoin Technical Support / Re: Transaction started with enough fee is not in blockchain. Orphaned? What to do? on: December 23, 2017, 10:03:43 PM
Assuming you are using the Bitcoin Core wallet...

If your transaction is not showing on any of the block explorers, then first of all don't worry, you still have your coins in your wallet. They just aren't showing, but they are there with your private keys, of that I am fairly certain.

To get them to show up in your wallet, I think you need to quit the wallet, then delete it's local mempool file (will be in your file system somewhere, probably in the same directory as your wallet.dat file). Then restart your wallet with -walletbroadcast=0 (if you are on a mac use the command line / terminal  "open /Applications/bitcoin-qt.app --args -walletbroadcast=0"). Then you should be able to right-click and "abandon transaction" on the transaction in the transactions tab.

I think this is what I did, though I may have had to restart the wallet after also.

As for the error you got from pushtx, regardless of whether your fee is high enough or not to get confirmed, this is strange to me, having too low a transaction fee shouldn't prevent your transaction from showing up in block explorers. It would only explain why a transaction hasn't been confirmed yet. So I don't understand this part.

Maybe someone with more knowledge can help.

(I have a similar problem with my transaction not getting into the mempools but the error i get is different, i'm told "missing parent". If anyone can help my thread is here: https://bitcointalk.org/index.php?topic=2637574.0.
7  Bitcoin / Bitcoin Technical Support / Bitcoin Core transaction not reaching mempools (missing parents) on: December 23, 2017, 05:58:26 PM
Tried to send all the BTC in my wallet to an exchange. Set fee at 0.004 BTC / kb

Transaction ID does not show on any block explorer. In BC, the transaction displayed as "0/unconfirmed, in memory pool" (I assume it means my wallet's local mempool).

After 48 hours, I extracted the hex code from the transaction (getrawtransaction) and ran it through https://blockchain.info/pushtx. This gave me:

Quote
Missing parents for MY-TRANSACTION-ID while inserting: [UNKOWN-ADDRESS]

After some searching it seemed I could try sending it again with higher fees.

So I updated my client from 0.13.2 to the latest 0.15.1, then managed to "abandon transaction" by removing the mempool file from my system and starting Core with -walletbroadcast=0 in terminal ("open /Applications/bitcoin-qt.app --args -walletbroadcast=0").

This allowed me to try sending the amount again, this time I upped the fee to 0.005 BTC / kb.

I got exactly the same problem.

It seems to me that it isn't a matter of fees at all. Because this isn't even about getting confirmations, I'm not even getting into the mempools. And that is not a fee problem afaik.

So it seems to me that the "missing parents" problem has to do with the source of my btc funds in my wallet. Both times I used pushtx on the hex, it was the same UNKOWN-ADDRESS being inserted that caused the error to show.

There are not that many transactions ("inputs"?) going into my wallet. Only 8. And when I inspect any of these transactions' details, they all show as confirmed. So I would have thought they're all fine. But this "missing parents" problem remains.

What can I do?

(Also, the reason I am sending the BTC is because I want to get at the BCH and BTG that is supposedly in this same wallet. And I wanted to move the BTC somewhere safe while I did that.)
