Title: Transaction not showing in blockchain
Post by: koston on January 14, 2018, 11:34:17 AM
Hey,

I've send an bitcoin-transaction 12 hours ago and after I send it it I realize that I've choosed a very low fee.
I've used Bitcoin Core and choosed the proposed transaction fee, because I thought that Bitcoin Core suggests the correct transaction fee.

I donīt find the TX ID in the Blockchain-Explorer.

How can I solve the problem? Does anyone have an idea?

Thanks!

koston

Hmmm, you sure you are connected to server, maybe something wrong with server or you are offline.
Also is you balance reduced my amount you send?

Bitcoin Core is up to date and synchronized.
Yes, the balance is reduced.
The status of the transaction is: unconfirmed, in memory pool.

Blockchain.info is just one of many block explorers, and it ignores transactions with low fee. There is no "one memory pool".
Your transaction does show up on blockexplorer.com (https://blockexplorer.com/tx/31b3e23780cf5e459ce8b2baeaf3582de97e1b412a8357b191d0a58f0beb341b). At 20 satoshi/byte, I would have expected blockchain.info to show it though.

At this low fee, it's very unlikely to confirm. It's best to abandon the transaction and try again with a higher fee.

Thank you for the answer!

What is the best way to abandon the transaction with bitcoin core?
I've never done it before. I have googled it, but I am not sure which is the right way.

First off all is that only transaction in your wallet? I mean if you send something before that and is not complected then maybe this is problem.

Also blockchain.info is showing all transaction even with extremely low fees.

My advice is to abandon transaction and move to better wallet, my friend got same problem with another wallet. Electrum if fine...

Yes, it is the only unconfirmed transaction in my wallet.
Because I haven't done it before, I am not sure how to abandon the transaction with Bitcoin Core.
Sounds very complicated for me.. ;)

This is not true, as the above transaction proves.

There is no better wallet than Bitcoin Core. It's the original and gives you full control. The fee problem isn't caused by Bitcoin Core, it's a result of the user being in full control.

What is the best way to abandon the transaction with bitcoin core?
Let me quote myself to answer this:
You can manually remove the transactions from Bitcoin Core:
-Exit Bitcoin Core
-Backup your wallet.dat, even though you should have a backup already, make another backup
-Start Bitcoin Core from a command prompt with options -zapwallettxes -rescan (if you're using a pruned wallet, you can't use this)

Depending on your hardware, it will take a few hours to rescan. After this, your transactions should be gone, but Bitcoin Core might pick them up from mempool again. In that case just wait for it to drop again.

Full description of the commands:
Code:
  -zapwallettxes=<mode>
       Delete all wallet transactions and only recover those parts of the
       blockchain through -rescan on startup (1 = keep tx meta data e.g.
       account owner and payment request information, 2 = drop tx meta
       data)
Code:
  -rescan
       Rescan the block chain for missing wallet transactions on startup

it seems lately bc.info mempool's minimum fee has been raised to somewhat high rate
a couple days ago I failed pushing a tx with 50s/B, bc.info rejected with message
Code:
Validation Error: Insufficient fee. Please try again with a higher fee.
@koston just follow LoyceV instructions to abandon your transaction
then you can resend again with higher fee, not too high, but sufficient for it to get included in the next few blocks
if you don't want to wait, you can import to another wallet and create a new "double spend attempt" transaction

@LoyceV - thank you for the information, I will try it. :)
@Thirdspace - also thank for the information

Is it also possible just to wait?
The transaction isnīt urgent.

Or is it necessary / better to abandon the transaction?

You can wait, but I doubt it will confirm any time soon. Fees haven't been this low in months now.

@LoyceV - yes, that's clear.

I've read that the mempools forget low-fee transactions after some days (maybe longer). An option is just to wait until this happens, but I can't evaluate if this information is true.

Bitcoin Core will keep broadcasting the transaction unless you manually stop it.
