Topic: Unconfirmed Transactions Problem - page 8. (Read 9372 times)

In the past few day, blockchain has received a significant number of transactions from many bitcoin users. According to some financial chart, the number of bitcoin transactions rise rapidly without any notice. I think people should calm down because you do not have to worry about this problem. It will be solve quickly

Have had my rather larger sends of bitcoin not confirmed and it has been close to 18-20 hours now.
The tx fees that were sent to cover the miner's fees were as per usual.
Over 0.0008btc should of been enough to cover the sent amount and have them delivered by now.
If this is an ongoing trend then I expect not to see many people trading bitcoin until this issue with the blockchain has been resolved.

Same here brother.
Had one last week not confirm until 4-5 hours and was getting worried that it would not fully and completely send to the recipient for 20 hours and I would have to refund them until it did.

Yes, I have also noticed that in the past day, the mempool has been quite backed up.

I have not seen much explanation from anybody regarding what is going on exactly.

The back-up from last week lasted for about 12 hours. 

I'm thinking that there is some kind of spam attack going on, because exponential peaks, like this, just do not make much sense.

As we can see from the linked blockchain.info chart, blockchain.info has only been providing (and tracking) mempool fullness data since early May 2016.

 I have a current transaction has been stuck for almost 19 hours, as I type, and zero confirmations, and the one that I had last week was backed up for nearly 3 hours.  Most of my other previously long transactions were  about 90 minutes.... otherwise most of my transactions had tended to go through in less than an hour.

I am thinking that the big blocker, blocksize limit arguing folks are kind of losing credibility with seg wit about to go live, and they may be attempting to get some attention to the matter by spamming the blockchain for the next few months..   That's my current theory and thinking based on my lack of information regarding some of the specifics, and my ongoing witnessing of the level of desperation, contradiction and bitcoin sabotaging that sometimes seems to be coming out of some folks from that big-blocker nutjobs camp.

Seems like it, but that's a pretty crappy attack these days. These spam attacks used to be very disruptive, but now the mempool cleanser has been introduced (I think that was version 0.12) as well as compact blocks, the sole effect is to push fees up a little.  I really hope whoever is behind it is feeling frustrated at how little they can disrupt the network these days.

You have to consider that many entities will send many transactions every day. $0.35 may not be a lot of money, but when spend hundreds or thousands of times per day, it quickly adds up.

If the transaction fee related costs continue to rise, then using Bitcoin may exceed the cost of using more traditional payment methods like credit cards and ACH transfers.

Yes maybe it is the cause of the growing number of users bitcoin. It sometimes takes a long time for confirmation if you want to send. I never experienced a transaction that has not been confirmed for around 5 days. Perhaps it should be fixed in order confirmation can be faster.

Looks like more an attack with several small transactions that anything else, the hash keeps the same from the miners, the transactions are getting into high values really, its insane someone be doing such thing for what delaying transactions from all.

Just to get clarity here you mean there are people who actually have control on how transactions are run for every satoshi sent and received

Interesting, where can we found some data like whom is spaming ?

Changed to 24 hour view, it is growing from about 10000 to almost reaching 50000
I am surprised now.

You can see live charts of the unconfirmed transaction queue at https://www.bitcoinqueue.com (my project)

This is by far the highest peak of unconfirmed tx we have ever seen so far... 

the transaction still delayed try to send my btc earnings from yobit to c-cex for almost 2hrs now but still nothing is
confirmed yet hope this delayed can be resolved while btc is rallying up.

Yes, today transaction is delayed too long.
I hope it will get fixed soon.

one that became my way to speed up the transaction is to increase the transaction fee. because the larger the fee, the faster also solve the bitcoin block in the system. it would be very helpful every transaction we do. 

OK, so you're supporting the blocksize trolls who push for unwise increases to the network burden without considering the ill-effects? At least things are clear now.



So, what are you, yes you John, going to do about it? Come on, wow us with your incredible never-heard-before insights into how to expand the capacity of the Bitcoin network? Oh, wait, what's that? You've got nothing but a bunch of hand waving? (and political soundbites from persona-non-grata Jeff Garzik, courtesy of his narcissists-anonymous account?).

You're a real productive, useful person around here, aren't you?

if you don't know, Your 2nd transaction won't get confirm as your first transaction is still unconfirmed.Try to contact with pool winner's the will be add your transaction on next block.Maybe with a little tip.

Nothing you can do but wait and keep patients

yes a lots of unconfimed transactions..

Even though you increased the fee. There will be no changed because of so many pending unconfirmed transaction. I think you became suspicious when the transaction takes too long to confirmed. When my 1 btc withdrawal takes 1hr without confirmation, i decided to stop withdraw other funds so that they will not got stuck up. Btw i hope our BTC will ne process as soon as possible.

Yeah, this is really frustrating I've been waiting for 9 hours this time for just 0.025 transactions, and I've send a small amount of btc to a gambling site but it as what others experiencing this time, its 0 confirmation since I've send it. 

Actually I believe it's a spam attack.
We've had it about a week ago too, back then the mempool rose to 23MB then and it took one day to clean up and get to normal.
Now I see again a rise to 16MB yesterday and one more started last night and still continuing, now reaching about 28MB. Somebody is clearly trying something... it's ugly and needs time to clean.. after the spam stops...
