Blockchain annoying issue

[rkandrades]

Hi...

Since yesterday my bitcoins are stuck on Blockchain.info.

I tried to do 5 transactions and all of them still UNCONFIRMED for more than 12 hours...

This morning my faucet dried because of this problem and I had to buy bitcoins in a brazilian online market. Translating: I'm losing money.

Somebody is experiencing this same problem or would know what I have to do to solve this?

How big in bytes, how high a fee in satoshi and do the TX rely on eachother?

Alternativly: TX IDs

I heard that there is a problem with transactions having double spent during thoses days so just when sending your coins (better with a fee ~0.0001 or a bit more) wait for the transaction to be confirmed and do not spend it over and over.
That's what I noticed from different users posts in btctalk, personally didn't made a transaction during this period.

Can you give us the url of the transactions or your btc address to check the transactions?

Of course.

Please, check it and help me to understand this.

Thats an address, which of the 69 transactions are you talking about? All are confirmed according to blocktrail[1]

I am having a similar problem. A transaction I sent about 40 minutes ago was "returned" to my blockchain.info address - without any action from my side. It was a payment, and the receiver confirmed the receival, but I have doubts it will confirm.

The transaction I sent as a payment still has no confirmations, while the "returned" transaction has already 3 confirmations.

Perhaps it's best not to use blockchain.info until this issue is resolved. I use it only for small amount, but nevertheless it is annoying. Annoyingly, blockr.io shows the same data, so it's not only a UI bug.

Nah look here https://blockchain.info/address/1AEdT62Tgfte4L6ni1e584BT4C1D5CH1tk
You will find the unconfirmed transactions and when checking them i found a double spent as expected..

I did a contact with the Blockchain.info support.

They send me this answer:

There is currently an attack on the bitcoin network that is causing these double transactions to appear. This attack is effecting almost all bitcoin transactions - not just Blockchain.info users. Your funds are *not* at risk and these duplicate transactions will never confirm. After 24-72 hours they should be rejected by the bitcoin network as invalid, which they are. When sending transactions during this attack you may see it appear twice. One will likely be marked as a double spend, which can cause a great deal of confusion.

We understand this is an inconvenience to our users, and all users of bitcoin. With your funds not at risk during this attack the most anyone can do is to wait for these transactions to be rejected. There isn't anything Blockchain.info can do to clear this issue up faster, as this is an attack on the bitcoin network itself. You can read more about the attack here - https://www.cryptocoinsnews.com/bitcoin-attack-coinkite-reports-malleability-attack-urges-caution/.

Yes a transaction malleability attack that's happening since some days ago. I think that many people are affected but it seems to me that the blockchain.info wallet customers are more affected by this than the others.

You will just have to wait as they suggested, until the transaction doesn't get dropped and this will take 24-72 hours.

On the other side I have sent 6 transactions yesterday, all using mycelium Android wallet. I sent one from Poloniex, one from Localbitcoins and 4 to my Trezor and I had no problem whatsoever.

Thanks... lets see.

Looks like we start here -> https://blockchain.info/de/tx/76e8dd7ea8a89939cf0dac72bdfa0ff961b1a3d555adb6f0ade27db8c9bf385f

However created that TX did not pay a fee.

The change from above unconfirmed TX is used here -> https://blockchain.info/de/tx/25d0095555d24b1325b5d90ac30315f3e53ee688d200de2f456bfbf421bc100a

This TX pays a fee of 0.0001 BTC, but it will not confirmed until the 1st TX is confirmed.

The change from above unconfirmed TX that relies on the 1st unconfirmed TX is used here -> https://blockchain.info/de/tx/d8d0d825daf90c5b6c51995cc5fe09aaf0856c306247e500d5ececf9f405f63d

This TX pays a fee of 0.0001 BTC, but it will not confirmed until the 1st and the 2nd TX are confirmed.

The change from above unconfirmed TX t hat relies on the 2nd unconfirmed .... is used here -> https://blockchain.info/de/tx/905dcf5726a3bfd952d8fc8d28514d401207188216afae8bbb7179fffe75071b

...

is used here -> https://blockchain.info/de/tx/59d4b6b8483610e4174d50ef3648730ad0b586b8b70daa880f80c8af834f40ea

Yeah.

I see no issues due to malleability. Its just plain not paying a fee and building TXs on top of that in the hopes that it changes anything, which it does not.

tl;dr: Just wait.

The transaction I sent as a payment still has no confirmations, while the "returned" transaction has already 3 confirmations.

That does not sound right, but I suggest you open your own topic.

Shorena, the first transaction with 0 fee was sent to an address (https://blockchain.info/en/address/19AcLEnoiQWoskfke1YDeweoKMUERBDpHx) that contains this :
Warning! this bitcoin address contains transactions which may be double spends. You should be extremely careful when trusting any transactions to or from this address.

I think that the transaction was double spent from the beginning and the 0 fee will delay the confirmation which in this case will  exceed 48-72h and finally return to the sender. Also blockchain.info support confirm the malleability problem. (am i wrong?)

But the input to 19A... is unspend. If you start from the 1st TX I listed and follow the spend (or rather used) outputs there is only one route and its still intact. I think its more likely that bc.i is answering with a generic reply without actually looking into each specific case. Bc.i also does not show a warning on any of the TX along the line which they usually do if there is a twin TX.

I am not entirely 100% sure you are wrong, but IMHO the signs point to OP trying to get away with a free TX in the middle of a 90k TX spam attack and an ongoing malleability attack, yet none of the attacks are the reason for the delay.

I can see what you mean. Thanks for the answer 

@OP: there is few wallets that pay your fees like xapo & coinbase if you don't want to spend the 0.0001 fee.

Well... The solution is to wait up to 72h and do not send new transactions between this time?

[shorena]

It might take longer, but yes. The solution is to wait until the TX all others depend on confirms or blockchain.info stops broadcasting it. When exactly the later happens I do not know, but IIRC its after 2-3 days.
