It has been half a day without a confirm. He was suppose to be sending escrow money.

I don't think so , if it was Double spend Blockchain.info should show a message about it .
As you can see it says Medium Priority , when you put the cursor on that sign near it , it will tell you that you paid inferior fees then the recommended ones and that was the reason of the delay , so you need to wait . In case it never gets confirmed money may just get back to the owner . Still ... don't trust 0 confirmation transactions .

That transaction looks like a bunch of small inputs transacted into one address, which shouldn't be malicious by itself.
Can you give more info about who was supposed to escrow, what etc.  Looking at the size of the fee, i'm surprised it still didn't confirm.

Idk escrow claims funny stuff might be going on and that he is no longer watching this, suggesting it will not confirm.

Looking at the adress I'd say it's OgNasty ? he is a trusted member as far as I know so there is nothing to worry about on that part , same goes for your items I guess ? I mean you didn't ship anything right ? so if that transaction don't get confirmed you simply don't send anything and that's it , you try to find another serious buyer to sell your goods .

Looking at the fee that was included and the address' history of what appears to be multiple double spend attempts, I am not going to follow this transaction anymore.

Let me know if it ever confirms (it won't).  ProfessionalGoogler, if you wanted to create a scam accusation, this address is all the proof you need: 17YEaLjrxygTBtm2aRgPmLvm8neUTkWmie

Please don't ask me any questions or debate this with me.  I don't want to waste any more time on this.

There's another unconfirmed transaction from those inputs (https://blockchain.info/tx/5d331af8fb81f39cdd95db47dbc9a7329016122fd9863a57492ca088e430a2ff) and it sure does look fishy.
Under no circumstances take it seriously if it doesnt atleast have few confirmations. I would search for another buyer in the meantime, and if this does confirm, ognasty will surely return it
to the sender if there's no trade.

seems the originating funds do not total the 4btc+ needed..
plus another 4btc was tx's within 3 hours, which again looks to not have enough funds..

It is a large transaction with a small fee. It is over 25 Kb. A good enough fee for that should be at least 0.0025 BTC, but the fee is only 0.0008, which is too small for a transaction of that size. It should confirm eventually. If the money is going to you, you could attempt a CPFP transaction to get it to confirm faster, or you can just wait for it to confirm normally.

Regardless of the fee, by my count also the originating address doesn't seam to have enough funds to cover all of the outputs.
I doubt it will even get confirmed.

That is not at all possible. No wallet would allow that, no node would relay the transaction, and blockchain.info would not accept that nor display the transaction. Your math is wrong.

Well I think it will confirm. There is no indication that there is a double spend yet.

I have asked for help in the below  thread.

https://bitcointalk.org/index.php?topic=232979.new#new

I chose the default fees that was asked uisng the quick payment method by bitcoin core client, and never knew this will casue me so much headache.

In the past, paymenst with default fees used to get confirmed in 2-4 hrs..

Based on some of the comments above, I may just have to wait

Even if it's outdated, I think it shouldn't be a problem derived from having an old version. Even tho is stupid to not update it, I think he simply didn't use the standard suggested fee.

Post by: tazdas on November 05, 2015, 06:45:08 PM
yeah , since yesterday my 6th sense has been telling me that i need to update my bitcoin client..  it must be calculating the default fee amount based on old numbers ( if indeed that how it works )..

Anyhow I have updated the client now.

Also I used the recommended fee, i never changed any amounts with the fee.

The default fee estimation needs to have Bitcoin Core be running for a few hours before it can accurately estimate fees. You need to start up Bitcoin Core and let it run for a while (long enough for a few blocks) before its fee estimate will be accurate. Otherwise you need to set the fee manually.

Believe it or not my bitcoin client had been continuously running for weeks . and I never restarted it before I sent the 2 payments ..  it must be the old version
