Unconfirmed Transactions Problem

[JayJuanGee]

  I`m waiting bitcoins to arrive for more then a half day, its clear to me now why some people are complaining so much about confirmation time. This is annoying as hell. Why they just dont change that 1 mb block size, from reading this comments that can make things works faster and better.
   Or I`m missing the point there, they could change that long time ago. Now with increase of transactions network cant process all that fast enough. When will they change this? Is anyone have some clue about it? Or this will be like this forever?

I doubt that merely changing the size of the block limit is the solution, especially when the apparent issue is a kind of an attack on the network, rather than blockage from actual transactions and organic growth.

There are probably other and better technical solutions, but I happen to not be technical enough to say anything, and really, we have not pinpointed, yet, exactly what is actually causing the transaction delays (what is the nature of the spam attack, this time and is it a recurring theme or is this a new kind of an attack, this time?).

Hi guys,

I hope you can help my newbiness and help me understand what is happen. I used coin mixer.se to tumble some coins, on the coin mixer website it says it 'sent' the coins successfully to my output address many hours ago.

However, no  coins have reached my output address.

What is more worrying for me is that wen I type the output address in the blockchain website, it says 'no transactions found for this address'.
When there has been a delay before, the block chain website at least shows the correct amount of coins heading to that address. However this time there is literally no information.

Should I be worried? Or is this basically what all of you are also going through? coin mixer.se set a randomised fee for me when i did the tumbling participation - so there was no way i could of controlled it or made it higher. I think there is also no way for me to go back and do anything.

Please let me know your thoughts !

Hi. The network is cluttered. If you used the service in the past and things went well you should not be too worried.
If you have a tx id we can see more.

If those transactions don't get confirmed and returned to their senders' wallets, so many shit on its way waiting for us. If bitcoin can be stopped in this way there is no way for that serious business owners will accept bitcoin again for a payment method. I hope it gets fixed soon.

It won't!

It's been like this for a year or so...

If the spam attack ends, the network will be like new until Saturday or Sunday!
But you have a valid point there, the network needs some big fixes, one being to filter out these attacks somehow and quick.
The normal mempool used to be up to 4MB and during the last attack it rose to 40MB.
Devs have to take seriously into account that the world is not nice and shiny, Bitcoin also has enemies and people that try to profit from any weakness they can find.

Hi,


Summary
Address   1CxhsVHTfL1eiGJ7PgF5ZX9V6TtL9Wrxt8
Hash 160   833260e3cadd463e85d630bd7ec27769e0d437ce


The address is the wallet that is supposed to receive the coins . I copied and pasted that from the block chain analysis website. I am not sure what hash 160 is, but hopefully this is all the information you need? If not then let me know where i can get the 'tx id'. Thank you SO much for helping me in advance... yes I have used the coin mixer.se website before and it is usually very good.... but for some reason this time i don't know what is happening. my biggest worry is that when i type the output address in the blockchain website, it is as if nothing has happened.

Sorry, the info you have doesn't help now. The hash 160 is basically the same thing as your address.
The tx id is something the sender should have given you to show it have sent your money.
But since it doesn't show even as "Unconfirmed transaction", the network doesn't know about it yet, so there's no tx id yet.
You...have to wait...

I made a transaction today, with a good fee, and I had to wait like two hours until the first confirmation from the network happened. this is pretty rare.. usually takes 30-40 minutes to get the first confirmation maybe the network is overloaded.
when this happened I could not stop thinking about the problem of bitcoin scalability , and we are probably under a spam attack

I wouldn't say it's constantly been this bad for a year or so but it has always been there and seems to be happening more often these days.

Who's saying that this is a spam attack?

[Looarn]

Who's saying that this is a spam attack?

In fact, someone have solid proof of that ? Seeing a peak is not a proof of spam attack.

If it was a spam attack that I should do, I'll use several wallet to send the monimum amount paying the minimum fees, so on the load we gonna see like an explosion of no fees to min fees.

That's not the case here.

Or I'm wrong ?

That's right we need tof see solid proof of a spam attack on the network before saying that and it probably wouldn't be too hard to find with the right program, just look for shit loads of small dust transactions.

The charts suggest that. How else could the unconfirmed tx pool jump from 2-4MB range to 40MB?
That's the current part here https://btc.com/stats/unconfirmed-tx

About a week ago there was another bottleneck, some 23MB high iirc, it took 24h to clear up, then all was nice for some days.

Somebody even suggested that miners may do such spam attacks to increase tx fees.
Shame I don't know of a better/longer history of unconfirmed transactions so I have to rely on what I remember (which is proven not to be very accurate for most people).

Do you have a better theory?

You're a liar. 13.1 was released today.

You know just as I do that a Bitcoin client with a 4x blocksize increase is now out, and that they've put months and months of work into it. Why don't you go and troll someone else's months of cutting edge technology work instead, hmmmm?

[gmaxwell]

Seeing a peak is not a proof of spam attack.

There is never any proof, short of the person transacting saying "it's a spam attack".

What we do have is an interesting change in transaction behavior reflected in the UTXO set: https://blockchain.info/charts/utxo-count?timespan=60days which coincides with the flood of higher fee transactions starting and stopping.

I could be wrong but I don't think it would be profitable enough and too time consuming for the miners to spam the network just to receive a few higher fees.

[NeuroticFish]

I agree to that. It's not the miners.
But I've already seen posts about double spends, for example. Some do profit from this situation and I feel like they're more than usual.
I would still like to hear a better theory for this than the possible spam attack.

Just got a confirmation after 16 hours and i feel lucky, lol

It could easily be "opportunistic piggy-backing", i.e. there is a real surge in transactions taking place due to the buoyancy in the exchange rate we have right now, and a spam artist  decided to use the opportunity to increase the pressure on the mempool.

Either way, it seems to me that it is currently too easy for the network to get overwhelmed. We need a quicker solution than SegWit.
