I have an unconfirmed transaction and/or it is confirming super slow. What should I do?

---

Be patient and wait. The transaction should confirm within 5 days. If it does not, tell the sender to resend with a fee. Do not ship goods without at least 1 confirmation. Please do not ask for help; it will not speed up confirmations.


Blockchain.info says it should be confirmed by now, but it is still not confirmed!

---

Blockchain.info's confirmation time is just a guess. Confirmation times may vary wildly, so do not be concerned when your confirmation time is long. Sit tight and your transaction will confirm.


How can I speed up confirmation in the future?

---

Use a wallet with dynamic fees (most do nowadays) and use the recommended fee set by the wallet. For fastest confirmations, always set dynamic fee to be the highest estimate.


How does Bitcoin's fee policy work?

---

Transaction fees are based on the size of the transaction. Sending to many recipients, or sending from a wallet that received "dust" transactions will increase transaction size. How much fee you pay matters as well; 0.001 btc/kb will confirm within the next block whereas 0.0001 may take several blocks. These policies are in place to prevent large blocks (bad for miners) and transaction spam (bad for everyone running a full node).


How do I resend a transaction?

---

Bitcoin-qt will rebroadcast unconfirmed transactions every 30 minutes or so. As long as the sender has his client open, the transaction will be rebroadcast.


How do I resend a transaction with extra fee?

---

For Bitcoin Core users:

• Right click the transaction and choose "Abandon Transaction"
• Send the coins again with a fee

Third party client users (https://bitcointalk.org/index.php?topic=231309.0)


How do I remove an unconfirmed transaction?

---

If you do not want to see the unconfirmed transaction, you can remove the transaction from your wallet (https://bitcointalk.org/index.php?topic=35214.0). Once the transaction gets confirmed, it will reappear in your wallet.

This should be sticked https://bitcointalk.org/Themes/custom1/images/icons/show_sticky.gif

If it is, I suggest adding the double-spending method to "If you sent the transaction"
https://bitcointalk.org/index.php?topic=231309.0


Why waiting? Afaik it's not necessary but I may be wrong.

You need to wait a few days for the transaction to drop from the memory pool. If you don't wait, the current implementation will treat it as an double spend attempt.

If you have a recent backup of your wallet, it would be easier to go back to that than to use pywallet. Just don't delete your "broken" wallet until you're sure you have all of your funds.

A week? Seriously???

Within a week. I stated this because confirmation time varies wildly. Don't want people getting upset their transaction didn't get confirmed within the average confirmation time. Worst case scenario IMO is a 0 fee transaction that normally would require a fee. Last time I sent such a transaction, it was confirmed overnight.

Does it require more fees when more transactions are behind it? I used to use faucets a lot, and I just sent a transaction, and it has a bunch of faucet transactions. That makes the transaction bigger, which requires more fees, right?

Yes

I have a large transaction that appears to have been abandoned by the network, no confirmations in 5 hours. I'm using Ubuntu 13.04 and when I try to get the dependencies I get these error messages:

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

I've already used the sudo command.

I can't wait a week because the transaction is to a temporary deposit address to CampBX that expires in 1 day, 9 hours. Any ideas? Any other ways to remedy this?

What dependencies are you talking about?
Could you post the tx you'd like to broadcast?

Well bitcoin-qt just corrected itself. 20 confirmations.

Dependencies:

Debian-based Linux:
 aptitude install build-essential python-dev python-twisted python-bsddb3

Stupid question: does deleting the transaction remove it from the network and put the coins back into your address so they can be sent again?

deleting the transaction does the following:

• prevents your client from rebroadcasting the transaction
• ...which causes nodes to "forget" the transaction ever existed (since unconfirmed transactions are not "remembered" after shutdown)
• ...which allows you to double spend the input to another address(since there won't be a conflicting transaction on the network)

I normally just delete the wallet and use my backup wallet !

My reaction to this is your avatar

I'm actually experiencing the same issue.
I sent from Blockchain.info, normal send (typically it includes a fee) but actually it says 0 FEE
http://blockchain.info/fb/16abbkq (http://blockchain.info/fb/16abbkq)

I am not asking for a warranty, but would it be someday processed?

Yes, I do think it could be Uncomfirmed for life

What happens if you skip step 2, double spending before the network forgot?

Notice: If you want a payment to go through in less than several hours, increase your Bitcoin client's optional/voluntary fee to something higher than 0.0001/kB for all transactions. Priority is given to higher fee transactions.

Some transactions sending large amounts of Bitcoin may qualify to be free, but you should add this additional fee in your Bitcoin's options, so that no transactions are sent without fee. The default additional fee is 0, which still allows some non-fee transactions to be created.

The Bitcoin network is very busy right now. There are several transactions a second being sent, and currently 6000 and 5MB of transactions are waiting for inclusion in the blockchain. Inclusion is what makes payments confirmed and trustable. If there were NO more transactions sent, clearing this backlog would take over an hour of maximum-size blocks.

Just the web page attempting to list unconfirmed transactions is about 2MB, and will make your browser crawl:
https://blockchain.info/unconfirmed-transactions


Also note: If you have already sent a payment with Bitcoin-Qt, the best thing to do is wait. Other wallets may make "bad" transactions, with less than the mandated minimum fee that will never confirm, but Bitcoin-Qt transactions will always confirm given time.

The first-post instructions for removing a transaction and re-sending a new one with fees apply only if the original transaction was created with a "bad" client, or if it was sent while attempting to bypass Bitcoin fee rules. Removing a transaction record from your client and re-sending another transaction will likely do you little good. The network won't soon "forget" your original transaction if it is properly constructed, will recognize a new transaction as attempting to double-spend the same money, and will discard the new transaction anyway.

Nodes which "know" of the first tx will drop the second tx as an invalid double spend.  It is very likely outside of some rare conditions that no miner will ever see the second tx or include it in a block.

Would there be any drawbacks to implementing nodes so that they would relay transactions they've seen before, with the only addition of extra inputs? I.e the exact same transaction but with an extra fee. Unless there's risk of blockchain spam, DoS attacks or something like that, that would be a great feature to have IMHO.

There is a plan for that, it is called "tx replacement" and it is partially complete no idea when it will be included in a release version of the client.  Obviously there are certain harmful double spend and other type of issues which need to be considered.

Another easier to implement option would be for one or more pools (HINT HINT HINT POOLS A WAY TO MAKE SOME EXTRA COINS HINT HINT HINT) to have a webform where you can supply a tx id and the pool will offer you a price (say 0.15 mBTC) to guaranteed inclusion in the next block the pool solves.  Give them the tx, send them the fee (as a new seperate tx) and BLAM your in the next block.  A "get our of limbo" card if you will.

In the interim using a 0.1 mBTC fee (or slightly higher) for ALL transactions (including high priority ones which "can" be free) is a good way to ensure you will be rapidly included in a block.  I have made about 80 tx in the last two days.  All but a few were included in the next block, the "slow" ones were included within three blocks.  Honestly it is a couple pennies and this is one instance of being penny wise and pound foolish.

lol, that's exactly what I am in need now, as I explain here:

https://bitcointalk.org/index.php?topic=348189.0

Can someone help me with this?

I am willing to pay as much as 0.01 BTC to get my transaction included in the next block.

sadly, no such pool implements such a system. i also doubt any pool admin is going to go through the trouble of manually prioritising a transaction just for you.

is it normal for a transaction to be listed as unconfirmed at blockchain.info but not show up, even as unconfirmed, in your wallet?

Like this

https://blockchain.info/address/1LQ9mnhGeKsuK3MXjvjpvSmAKgJxKwdZMT

Do you mean confirmed?  Because that's listing as 39 confirmed.  No, it isn't normal.  But I've had it happen with Multibit and it's generally fixed by resetting blockchains and transactions under Tools.

No it was unconfirmed at the time I posted it.
It went through. Turns out the escrow accidentally sent it without fees so it had to wait in line for a while lol. Went through though and everything is fine now.

CoinMKT is telling me they sent my withdrawal to this wallet:

https://blockchain.info/address/1EbwbMgEnh4ajnQsNhqwgk7fcjCcBxMkez

but nothing is on there at all.  Could they have sent it and it's just not showing up at all?  I thought it would show up on the blockchain but just show as unconfirmed?

Yes, of course.


blockchain.info is not the blockchain, neither it is a full report of transactions going through the bitcoin network at any given time.
There are plenty of reasons explaining why a transaction was sent by someone and you don't see it on blockchain.info.

All these reasons are not relevant once the transaction makes it to a block, at this time you should see it within few minutes on blockchain.info as well as on every nodes. I suggest you just wait a bit, I'm 99.9999% sure that your post was made too early and you'll just say "oh, I see it now!" :)

THanks - I have just never had this problem before after tens of transactions.  Plus it is my first withdrawal from CoinMKT so I"m more worried than normal.

However I have been waiting 8 hours ...  :-[ and I paid the .0002 fee to make it go "faster."

Well, to update, it took like 9 or 10 hours but it did show up.  It was odd because I had paid and fee and everything to speed it up.  But it was the first time I just didn't see ANYTHING in my wallet, even that it was unconfirmed.

This is likely the fault of the service not actually sending the payment until later, not delayed processing on the part of the Bitcoin network.

In answer all my questions, definately a good source for beginners. "Be patient and wait." :)

Not to be too repetitive, because this was suggested earlier in the thread, but this would be a good sticky. 

yes it does. however, each coin may have a different fee policy and/or block time. please take those variables into consideration.

Someone sent me a very small donation (0.00121 BTC) without paying fees. I don't know who sent it and I know this type of transaction are rejected by miners. Take a look at it below:

http://imagizer.imageshack.us/v2/xq90/844/v5g8.jpg (https://imageshack.com/i/ngv5g8j)

Even with a low probability of confirmation, I was hoping that after a few days it could be included in a block, but Blockchain.info simply removed it (I know
the sender sent from a Blockchain.info wallet, because he added a note):

https://blockchain.info/pt/tx/3cde47ee3979a46b36bd61bdb0caf9c11dea58ac99f17fb17b95728766de70e0

Does it mean this transaction has gone forever? I mean, what exactly happened to the bitcoins sent? Are they in limbo now?

Now my bitcoin-qt shows it as Unconfirmed. Should I delete manually this transaction from my wallet?

It would be nice if the receiver could have a chance to pay the fee when the sender didn't pay any fee. For example,
I could pay a fee of 0.0001 BTC and receive 0.00121 BTC. In the end I'd have 0.00111 BTC. Better than nothing.

Ben Davenport answered my question in the bitcoin-devel list:

"You can create a transaction which spends the output to yourself, attaching a fee to that transaction. In order for miners to grab the transaction fee on that transaction, they would have to also mine the original transaction. Likely, you'd have to do this by hand, but software could be written to simplify doing it. No protocol changes needed.

Ben"

This is good news. It's good to know the possibility exists. We just need it implemented in the software.

I have the same problem as the guy above!

Correct me if I am wrong, but I thing waiting 48-72 hours is sometimes not necessary.
If you send transaction with very low or no fees it will not propagate in the network very well. It might even get stuck after being announced to a few nodes. If you send coins again with the fee and use only the nodes that has not received your first low-fee transaction then you do not have to wait more than several minutes. Using only uninformed nodes should not be difficult as this will be majority of network (your low-fee transaction is stuck only on several nodes.)

I think you are right but i really want to know how to use nodes that has not received your first low-fee transaction because i sent 0.01btc from blockcain.info with 0 fee and it wasn't refunding those coins after 24hours so i decided to double-spend on my bitcoin qt 0.8.6 while it was synchronizing(about 20hours behind or so) and no active conections to the network i sent those coins and then i checked the tranasctions id on blockchain.info/tx and other blockchain explorers it sayed that tranasction dose not exist what could be wrong and why and why does this happens?

It is difficult to choose nodes manually. I think it is actually possible with some low-level approach. (Probing nodes by IP, accumulating more nodes addresses, requesting specific txids form nodes, connecting selectively to such nodes that do not know about previous transaction.) But I do not know if you have to modify and recompile your client or if it can be done by RPC calls. It is quite difficult both ways.
What I actually meant was not to try this manually, but hope that your low-fee transaction is either:
- too low fee and thus unpropagated and thus it is only matter of time and trying to double spend
- reasonable fee and thus well propagated and it is only matter of time when someone will include it
(so it should work automatically)

Unfortunately in this case, blockchain.info has some very well connected nodes and it sends transaction to big part of the network. So you can not double spend, because low-fee transaction is both of above :-/. Both well propagated (due to blockchain.info initial propagation is always well) and too low fee (that is why it does not propagate further and why it is not included by miner). When you try to double-spend, all nodes you connect to probably already know about prior low-fee transactions.

I think, you can only wait and if AFTER rescan you will not see your previous (unconfirmed) transaction, you have chance to double spend. Or maybe the transaction will get included in low-fee variant after all. But, again, you have to wait :-/.

I tought transactions are allmost instant and there is no fee. That was reasons i bolieved btc is better than plastic. Who get that Bitcoins from fees anyway?

Im having a small problem with the blockchain today. Its been close to 3 hours and no confirmations....even though my QT wallet says 11 confirmations. I paid the recommended fees and checked the propagation and shows network at 26% with about 700 nodes connected....so will this transaction go through or do I have to rebroadcast or reload backup wallet?

Thanks
Bgw

All set guys....blockchain was extremely slow today

Thanks

What is transactions, how these works, how to buy bitcoin, how to earn?

Thanks

Start here: http://www.coindesk.com/information/

Then look up bitcoin on wikipedia

I was just going to ask about this because I'm getting a lot of those type of messages in my error log as well transaction already spent? I just sent some money in exchange for paypal, and I don't want to come across as untrustworthy, I'm keeping in contact with the seller but I really want to know if there's some way to fix this? I feel really bad that this isn't work out faster or better for me and him but I have no idea why it's not working faster.

For reference I have the 64 bit bitcoin-qt and I'm on semi slow internet. It wasn't a large amount (about 50 bucks worth) so it really shouldn't take this long right? I sent it over an hour or so ago, it should have at least one confirmed but it's not.

Did you pay a fee?  What was the transaction?  (This should probably not be in the FAQ section though).

Hello!
Thanks! This post is really helpful! I was going to start a new topic but this post solved my answers. I found a site all about confirmation :- https://en.bitcoin.it/wiki/Confirmation . Maybe it will help some.  :)

I couldn't understand what is your problem. I saw your photos but still confusing.
Can't you send btc to other address? Is that your problem? Can you explain?

Kindly,
        Muhammed Zakhir

One thing that worked for me is spending the change from my no-fee transaction with a fee high enough to cover both. It still took longer than usual but they were both confirmed within an hour or two.

Well ok,

I've had two transaction unconfirmed (sent by blockchain), definitely don't have any HD space nor connexion allowing me to install btc qt, etc...

https://blockchain.info/fr/tx/da08920045d17cbb983bd4079760ef5446a717fc8742d4128a3319e3048d4957

I promise a bounty to whoever manages to help me -help hem go through?- with that (0.016 or so...).

One already got 6 confirmations but the other will take some time. It is stated that it has medium priority. So Wait for 1 day, it will be done, IMO.

Kindly,

Does someone know why this is still unconfirmed ???

It isnt, but according to the link you paid no fee. This usually leads to your TX waiting for a long time till a miner finally takes a heart* and confirmes it.

* thats not techincally acurate.

it's already confirmed after renewing the QT.

May I ask you why you are posting here? :) it isn't the correct section. Please start a new thread to get most help from others. Good Luck! :)

  ~~MZ~~

that's more like it, a week is really too long for me.

I was just going to ask about this because I'm getting a lot of those type of messages in my error log as well transaction already spent?

can someone please explain me why this transaction has not be confirmed yet? https://blockchain.info/tx/946cacddf93116e4511fd5a47ab01bdb9e68679cd6a11de794fad126af3d3ec0
even if it has 0 fees:

It is smaller than 1,000 bytes.
All outputs are 0.01 BTC or larger.
Its priority is large enough (411159279*69/225)

thanks

Probably because it looks like there has only been one block (maybe 2) since it was created.

It has been nearly 45 minutes since the last block.

Thanks for the answer but that's not the reason
It was created 2015-04-07 22:08:00 and now it s 2015-04-08 01:38:55
So 3 hours and half have passed

And your transaction is confirmed in block 351193, 242 minutes after creation. :)

From my personal experience, 0 fee transaction will take quite some time (up to a few hours) to get confirmed even when it satisfies all the 3 conditions. If you need it to go through fast, it is better to include a transaction fee.

Yes, they take time. The reason behind this is that there is only 50KByte per block for transactions without a fee by default. Thus you are not competing for a spot within the full 1MB of a block, but for a much smaller space.

thanks for the answers. yep finally my transaction was confirmed. there were a lot of blocks with just a few transactions, before the one in which my transaction was confirmated, so to me it looks like a waste of time to wait so much.

This is essentially what it boils down to. Either you want the transaction confirmed fast and pay a fee or you have a bit of time or do not care if it takes longer and can get it confirmed without paying a fee if other conditions are met.

I tought bitcoin protocol allowed to send transactions basically free but apparently miners don't allow that.
There is always such confusion around transactions fees

You can send a zero-fee transaction but it will take some time to get confirmation. Some miners don't add transactions which have less than recommeded fee but most miners add all transactions but give priority to transactions with recommended fees.

There is no minimum and maximum. However, you can take 10 minutes as minimum but it is not really true in all cases.

Is there any service for manually adding a fee to a pool? Created Transaction using blockchain.info wallet... Usually it takes some fee, but in this case, it doesn't for some how... It is <0.5 kb , only 2 outputs >1 btc each and it says High Priority. But It takes 6 hours for now, and it still stays unconfirmed :(

Can you please post TXID?

P.S. You can use Blockchain.info custom spend to set a fee of your choice.

Transaction id

https://blockchain.info/en/tx

I used Iphone application, it doesn't include option for any fees at all. But usually it adds 0.0001 fee. On a computer-browser version my fee is set to 0.001

Thanks! It confirmed now! Muhammed Zakir, It was you?

It is confirmed. Now it has 3 confirmations. It took time to confirm because you didn't add any fees.


When I used to use Blockchain.info, fee was added. I don't know why it didn't for you. There is a change Blockchain.info didn't add it because of the high priority* of transaction or there maybe some problems.

* I didn't calculate priority of the transaction.

Edit:


Of course, not me. I don't have any magical power nor do I have a miner to do it.

As I understood, blockchain.info didin't add fee automaticly, because even without fee it was High Priority Transaction. For now, I change fee policy in my wallet to add 0.001 to each transaction anyway.

My transaction has been stuck without confirmation for > 2 days. 

https://blockchain.info/tx/1efea73fc797ae98edcaf9f407742152bd473cef6fbd4376326b330da558e379 (https://blockchain.info/tx/1efea73fc797ae98edcaf9f407742152bd473cef6fbd4376326b330da558e379)

Is there anything I can do to confirm this tranaction?

I own the privatekeys for these 4 wallet addresses involved in the unconfirmed transaction:

I used electrum to send the first three transactions and bitcoin-qt for the last (v0.10) on linux.  I tried pywallet to remove the transactions.  It looks like my first three tranactions are now merged into this one.  Notice the double spend warning on top.  I turned my qt and electrum off for now.  Anyone know what is going on?

Well if Bitcoin is meant to be king why would anyone want to wait 5-7 days to receive there payments just as well go back to the old cheque book method if thats the case

https://blockchain.info/tx/332c8589498d46cd1767988b3db6248bbdce539871aa37dbaf38da273323cd3b

#1 its not even 2 days
#2 your fee is low even without the current spam; 1650 satoshi for 373 bytes
#3 the network is currently heavily spammed, if you want a fast transaction you have to pay a higher than regular fee.

I get email notification from freebitco*in payment
but while I check blockchain*info account , my balance not update till now more than 48 hours ago
any problem at blockchain?

Did you check whether your address received that transaction or not? Use Blocktrail.com, btc.blockr.io and Blockchain.info and see if that transaction shows up.

Here's an audio clip that might be of use to anyone reading this thread.

Andreas A. discusses the three ways to change a too-low-fee TX (https://soundcloud.com/mindtomatter/ltb-e234-doublespends#t=40m14s)

• Wait & Resend - Discussed above in this thread
• Replace By Fee (RBF) - Patch available to recompile Bitcoin-QT with RBF support.  Mining pool support is unknown (by me)
• Child Pays for Parent (CPFP) - Already implemented in Android Wallet and Eligius mining pool

I have a Cryptsy BTC withdrawal that has been either not showing or showing Unconfirmed for 3 days

The fee was lower than I would normally set but in this case I used a free w/d coupon so it was set by the sender 226 bytes / fee 0.00002363 BTC

Blockchain never recorded the transaction giving this message “Transaction rejected by our node. Reason: Unable To find all tx inputs”

Blockr did originally show it as Unconfirmed for a couple of days but now doesn’t show it at all

Blocktrail still shows it as Unconfirmed - https://www.blocktrail.com/BTC/tx/cf9e13855beae75131101f201d33ba946cbe2afe009e4bf8dd702e763dd45e58

Does the fact that it still shows at blocktrail mean it might be processed within the 5 day waiting time recommended at the beginning of this thread or am I wasting my time waiting any longer and should request a resend now

And would the fact that it is still showing as Unconfirmed at blocktrail make a resend any more complicated and if so how long might it take for blocktrail to not show it?

Thanks

I need help regarding two transactaions which are showing up as 0 confirmatiosn for last 24hrs

What can I do get them to confirm ? Kindly help.

regards

Wait, you might want to consider paying a higher fee in the future. There are many transactions currently waiting for a confirmation, once those paying a higher fee per byte are confirmed yours will get a confirmation.

Many thanks for the advice :)

Ok so looks like both of my transactions in questioin here now have confirmations .

Should be all ok now

Wow! Thanks for this guide! I finally understand why my smaller transactions take much longer to confirm

I also suggest you to delay your deal until transaction gets confirmed..
And wait for few days more..
Sometime it happens when there are too many blocks or depends upon transaction fees..
So wait otherwise it will be double spending for sender...

I have a sending transaction in bitcoins2x.com, I wonder why I don't receive The 3days. These is my transaction. It appear on my coins..pH that it send

I set up a simple form to (re)broadcast bitcoin transactions using either the txid, or raw transaction

I heard this might help, but I make no guarantees

http://services.moloch.net/broadcast

http://services.moloch.net/images/tx_broadcaster.jpg (http://services.moloch.net/broadcast)

it was working well until you put that - 66: Mempool Min Fee Not Met

Hmm, yeah... the thing about that...

If there are too many pending transactions, you get that error when your transaction does not make the cut...

Basically, there are 18,000 people in line who are willing to pay a higher fee than you

I set the mempool to 500MB (default is 300MB), but there are currently over 18,000 unconfirmed transactions... cumulative fees for unconfirmed transactions are up to 1,282.62774345 BTC! (an average of 0.071 BTC fee per transaction?!?)

HI Guys

I made a couple of cash outs more than a week ago and still see nothing in my wallet. Can you please assist.

Stefan

#1 which wallet/service?
#2 from where to where di you send?
#3 tx id?

Hi

I'm using Blockchain "MY Wallet"
I transferred bitcoins from BITFactory to My Wallet
My Wallet address is 1FKez51GxTVNtSBdBG9bsKaynCfP6EyEW2

Stefan

Since you are talking about BITFactory and assuming you are talking about blockchain.INFO (vs some other blockchain service or the blockchain),  you should talk to BITFactory technical support.   If you tried to withdraw from them, did they give you a transaction ID?

You also might try asking in the correct thread.

my node behaves strange, after mem usage on mempool gets close to 300Mb suddenly all inputs get lowest priority enforcing higher than usual fees, all gets back to normal with restarting daemon every 2 days

AFAIK thats normal with 0.12 (core, not sure about classic) as 300 MB is the default limit where the node will drop TX from memory and raise the minrelayfee. This would also affect its feeestimate.

yes bigger transaction required bigger fees.so that transaction can made faster as soon as possible.
and if you don't spend anything any fees sended btc will reverse to sender wallet automatically. ;D

No, this depends on the wallet the sender uses.

sometime they take really long to get confirmed

It has now been over 5 days since I accidentally sent bitcoins with a too small fee from my old wallet to my new wallet, and it has not been received.

From: My bitcoin-qt.exe, version v0.8.3-beta. At 2016-05-10 11:06.

To: My new Electrum wallet version 2.6.4.

Transaktions-ID: 487823c8ab2d791828241409d004f56cecc8523e84cc87caeaddb0431aa4b5d8

Please advice me to how I can either cancel the send or to make it go through?

Thanks,
Fredrik

Thanks again! :)

hello,
anyone can help me?
i am confused now.
6/6/2016 i made transaction using blockchain and the transaction is unconfirmed for 2 days.
yesterday i saw the amount back to my wallet and suddenly it appears again in my blockchain transaction.
is there any way to cancel it stop broadcasting after rejection?
or how long i have to wait the bitcoin back to my wallet?
the hash transaction is fe09397d068f68fc3656d345e8e6621a3b7a1e301e50dd7884a84e42128ca6d9
for the worst case, will the bitcoin loss?
because i am really confused now.
anyone can help me will have a reward given.. =)
cheers

Hmm, https://blockchain.info/tx/fe09397d068f68fc3656d345e8e6621a3b7a1e301e50dd7884a84e42128ca6d9 indicates the transaction was received less than 2 days ago but perhaps it started before that elsewhere in the network.  The whole trick is to get it forwarded to miners.  Many (most?) nodes will refuse to accept transactions without fees.

If you had included an appropriate fee (instead of zero) then it would have gone through quickly.  https://bitcoinfees.21.co/ provides guidance; it is currently indicating a delay of 840-infinite minutes for transactions with no fee.

Which wallet are you using?  Many (most?) wallets these days have a feature to redo the transaction with a fee.

Hello Sir.
I am using blockchain legacy wallet.
Do the wallet allows to redo transaction with fee?
I am actually put a fee for the transaction but i dont know when i send the connection is quite slow. Maybe my internet connection is bad. And suddenly i saw the fee is zero.
Any idea to help me?
Sir. You said the trick is forward to the miner. How to do that?
Thank

And 1 question. Will be bitcoin loss??

Hmm, you should convert away from the legacy wallet.  Even the old wallet used a default of 0.0001BTC for the fee but this was manually overridden (don't do that).  I don't see an obvious way in the legacy wallet to redo the transaction to add a fee; we need to research that.  Worst case we might be able to load the private key into another wallet that does offer that feature.

After you convert, Blockchain says https://blog.blockchain.com/2016/03/16/introducing-dynamic-fees/ so it will calculate an appropriate fee depending on the current traffic.  The speed/quality of your internet connection is not the problem.

No.  Even without redoing the transaction to add a fee, odds are eventually the transaction will be included in a block so, no, the bitcoins will not be loss.

Thank you reply my post, Sir

Yes, someone in this thread reccomend me to use a private key to another wallet. But that one i am quite worry because i am not good in this. I worry anything will goes wrong.

Since everybody said the bitcoin will not be loss. I will be calm now. I just worry it will stuck there forever. But i think it wouldnt be happened.

After this case. I will convert to the new beta blockchain wallet to get a better TX fee. To avoid this case happened.
Thank you Sir for replying me.
Have a good day.

Your transaction was pruned by Blockchain.info (which just means I can't check on the progress that way); so, what is the address involved instead?

I think electrum is not working, the wallet is guess work to what is actually happening in the wallet, i don't understand it, i am trying to send a BTC payment to an address but the person i am sending it to is not getting it, electrum dont even have support, they send you here to figure everything out which is not helpful, when the amount is showing red on the electrum wallet page, what dose this mean ? any body out there willing to guild a newby like me on how to work out how to actually operate electrum wallet so i can pay people with my balance which i have in my electrum wallet ?

Any help at all would be very appreciated thank you  >:(

Electrum is working pretty well ...  and about support , sorry but you are wrong too ... electrum is one of the most maintened wallet with a great support ...  
- you can PM directly Thomasv , here on Bitcointalk , or you could go to Electrum IRC room ,on freenode,  i assured you on the fact you will get all the help you could need ..

a good start should be here :  http://docs.electrum.org/en/latest/ (http://docs.electrum.org/en/latest/)

http://prntscr.com/bfe64f

1- i used manage wallet ( repair wallet)
2- i reinstalled wallet
3-i used special words on breadwallet but it says word does not match even words are correct and  i recovered words on multibit HD on pc they acceopted words but in the end they again unconfirmed all my transections after verifying blocks   http://prntscr.com/bfe64f
4- i installed multibit HD on other pc and used phrase but in the end it again it took all transections to unconfirmed.

i feel the reason of this error may be

i have many tiny transections may be becouse of it ?
i received every payment with new btc adress.
i had network issue when i was receiving these payments..

please if someone can help for this and can you please tell me other softwares or clients which accept multibit HD phrase like breadwallet .
and i needed multibit HD support ,email or contact .

Did I just get scammed here? Has this been double spent?

The fee seems sufficient but currently there are over 18700 unconfirmed transactions^[1] in the network.
Maybe you will have to wait for another hour or so.

Hello,

My account is: https://blockchain.info/address/16uEg5LvVwdzsPqnxTyGzfKbZeo4cR8fak
I got mission from my company to sweep key. The transaction is 4days already but no confirmed, Blocklchain support said wait it will auto refund back to sender account.
Im using Electrum to sweep. I am very afraid of being fired :(

Thank you very much !

Don't worry about it. Eventually, the mempool will forget about the transaction and you can respend the inputs. You can also try doing a manual double spend. Next time, use a larger fee. 0.0005BTC isn't enough for a 20k bytes transaction. People with smaller transactions, like 500 bytes usually use 0.0001BTC+, so for miners, it is less profitable to confirm your transaction. When you resend it, use at least 0.003BTC in fees (0.00015BTC/kb) so it will actually confirm.

Yes, im waiting 5 days already but everyday, blockchain update received day.. I cant find  the transaction in blockexplorer.com but blockchain always update it :(
Dobule spend can cancel the transaction? :(

Hello guys i am having trouble with my transaction can anyone help me ?

https://blockchain.info/tx/985324471273def41aef2bd3c99fc4d3ccfcfcddc38a2ee6653d312ca4fa27a3

this transaction is still unconfirmed and i need it to pass can anyone help me ?

Status: 0/unconfirmed
Date: 14/06/2016 12:59
To: Send to  wallet 1ESz2tJ35T1VU9KA2JHHTjXEuWhP9Xgqj2
Debit: -0.01065500 BTC
Net amount: -0.01065500 BTC
Transaction ID: 3797806a3b79df6588222329c1641809577506a796f8cbc0dc4d67a3b857b678-000

As you can see, I sent the above on 14/06/16 and still have no confirmations to date.
I am using Bitcoin Core wallet version v0.10.3 (64-bit) and cannot update as I am running OS X 10.6.8

I sent with a small fee, but the tickbox "send as a zero-fee transaction if possible" was ticked.

Have read the pages in the forum and see that people keep giving the advice to cancel the transaction and resend with a higher fee or to double spend.

Cannot see any way of cancelling the transaction. Have looked everywhere within Bitcoin core several times and do not see any option to cancel a transaction.

I need somebody to explain VERY simply how I achieve this or how you would be able to double spend.

I have sent many bitcoins to other addresses since and had no problems, but I still have the no confirmations with the above transaction.

Can anyone help?

My first transaction was unconfirmed for a week, then I had to stop Electrum and start it again. After that my transaction has 1151 confirmations! From nothing to a huge confirmation.

Is this expected behavior?
Best
Fran

Electrum sometimes does not update its data from the server, not sure why but restarting it usually fixes it. Its not that there were 1151 blocks found in quick succession, but that your wallet was out of sync for almost 8 days.

did i mess up? how long are these gonna take?

edit: went through, took 14 hours

blockchain.info is not the blockchain, neither it is a full report of transactions going through the bitcoin network at any given time.
There are plenty of reasons explaining why a transaction was sent by someone and you don't see it on blockchain.info.

I am stuck with my transaction: https://blockchain.info/tx/1b2b6d5692df0b166e383de46947efe0c5f35044eed9d8d4df0ffb1546304993

It's not getting confirmed since 2 days now and I did a mistake by adding a fee below the recommended one. Should I just wait or is there any chance of it getting dropped by the network? Should I try to double spend it to the same receiver?

Hello, what can i do to complete the transaction? Here is my problem: https://blockchain.info/tx/c8847648f5d23e02fccfeb727cd3cd3067a300db20a0212f4b2a478a9b73e851 (https://blockchain.info/tx/c8847648f5d23e02fccfeb727cd3cd3067a300db20a0212f4b2a478a9b73e851) , I using bitcoin core and I don't know what to do. I wait 7days but still nothing. Help! please

You haven't added any fee to your transaction which is why it will never get confirmed. Follow the instructions given in this video and double spend those coins which are still in your wallet and have not been sent due to 0 confirmations. Add a fee of atleast 0.0003-0.0005 to get the transaction confirmed fast.

Given the lack of a fee it might never go through as is as it competes with fee-paying transactions.  If you arrange for your wallet to stop retransmitting the transaction then eventually the network should forget it.  I haven't done it myself but apparently the right-click abandon transaction is the thing you need.  After that then you can send a new transaction with an appropriate fee which will go through in a reasonable amount of time.

My transaction has remained unconfirmed for 19 hours. Originally sent using Electrum wallet w/ a fee of 0.00011382 BTC for 225 bytes.

https://live.blockcypher.com/btc/tx/7683eaf16ee48fe4034b413859f94f928499be66f04cecf588b20d8d1a95786c/

Attempted a fss-rbr using coinb.in but wouldn't go through. Followed these steps: https://www.youtube.com/watch?v=ycq7O48aPvQ

All my funds are in the same wallet and I don't want to attempt another transaction and have it stuck as well. Any help?

Your fee of 50 satoshi per byte is half of what is recommended which is 100 satoshi per byte. It may confirm soon but there's no guarantee. If you want it to be confirmed faster try doing what I posted here (https://bitcointalk.org/index.php?topic=1701673.msg17061114#msg17061114).

I have a transaction , ID 8aa4db7b1454f019d3a56a57a67ef511d934c40277f73163888f3db81cb250a3  unconfirmed even after 3 hours. Is waiting , only option. Both the wallets ( origin and destination ) are web wallets.

Since you are using a web wallet, you likely don't have much control so it will be difficult or impossible to perform an RBF transaction. All you can do is wait. You can try contacting Quickseller (https://bitcointalk.org/index.php?action=pm;sa=send;u=358020) and macbook-air (https://bitcointalk.org/index.php?action=pm;sa=send;u=16114) as they are known to have been able to help people with this.

Thanks for the reply..  the fee added was sufficient.. still its showing pending.. is it possible that i may lose these BTC ?

No it is not. Your fee is ~65 satoshis/byte. According to http://bitcoinfees.21.co/ the current recommended fee is 100 satoshis/byte.

No. Bitcoin does not just "disappear" or magically become lost due to an unconfirmed transaction. Either the transaction will be "forgotten" and your wallet will revert to a state where that transaction never happened (i.e. it "returns" to your wallet) or the transaction will confirm and the Bitcoin will go to the intended recipient.

I withdrew it from a games website , and it was automatic withdrawal , so typically i do not have control over adding fee or if btc reverted to do anything. please suggest me what to do

Contact Quickseller and macbook-air as I said in my first response to you.

Can anyone tell me a wallet thats is not as expensive  as blockchain?

All wallets will require that you send a transaction fee. The transaction fee does not go to the wallet developers or the service running the wallet but rather to the miner who confirms your transaction. The fee is really an incentive for the miner to include your transaction sooner rather than later.

With the Blockchain.info wallet you can set the amount of fee manually

I was waiting from noon about five hours and jump to
https://www.viabtc.com/tools/txaccelerator/ (https://www.viabtc.com/tools/txaccelerator/)
After two hours I got my confirmation finaly.

waiting 24hours already and more,my friend is waiting 48 hours

dont know what to do  ??? ???

Check this review for viabtc tx accelerator service http://coinour.com/index.php/review-viabtc-bitcoin-transaction-accelerator/
In case you have any question, you could pm me.

Have been perusing several of these "unconfirmed transaction" threads yet don't think I have seen my forthcoming question asked quite this way:  In order to make an unconfirmed Bitcoin transaction drop more quickly from the memory pool; should I leave my Bitcoin Core wallet shut down (turned-off/not running)? I have done -zapwallettxes twice and the transaction is still there (it's been 48 hours). Also, 'abandon transaction' is grey'd out on my left-click menu. I am running Bitcoin 0.14.0 (64-Bit).

I ignorantly had this happen once previously, but did not catch my (at the time purely unknowing) mistake for several days. (Unsubstantial transaction fee ::) )

This time I more or less did it deliberately  ;D  ::)  and was wondering if there were any other options besides waiting the 72+ hours to be able to resolve this.

I have been waiting over a week now   :o

sent from blockchain.info the transaction seems to be rebroadcasting the transaction, preventing it from expiring because the date keeps changing

was the 15th, then the 19th and now the 23rd

will it ever expire and be forgotten?

Join the club. I figure $800+ would be handled in under and hour. I guess not...

https://blockchain.info/tx/9d3971f59c4dfcf9f7f6f42e826703596e3aa219947f650ae7956947353d992c

Isnt it great that the amount you transfer doesnt matter?

Post pretty old...very interesting. Thought the unconfirmed Transaction thing is a recent phenomenon. Think Op should update the post to meet current reality

Isn't it great that the monetary amount you transfer doesn't affect the data or processing cost to network members, or cost of disk space that nodes must allocate to store your transaction forever?

Well, anyway, the commentary should be that if it was important to have processed quickly, then paying a larger-than-default fee would have been a much smaller percentage of this non-trivial amount.


My amendments below to the first post's points still stand valid - don't experiment with paying the lowest fees possible for important transactions:


The Bitcoin white paper doesn't say anything about free or cheap transactions, this came from Bitcoin promoters while it was still true. In fact, reasonable and balanced fees are necessary to discourage trivial transactions and to replace the shrinking block rewards paid to miners. The economics of this are competitive and self-correcting - as more transactions pile up, more fees are needed for timely confirmation. What hasn't happened in the last five years is exponentially cheaper hard drives or processors that could have kept Bitcoin data growth less expensive.
