Hi everyone. Sorry for the trouble on that.

This tx did cause us some issues. https://coinbase.com/network/transactions/88eb395b48a6d3875d8d55a6efd34afd2e1d4e397b43f9f790479914fba0c74b and should not have been used as an input - that was our error.

We are pushing out a fix for this now so transactions like this should not be used in the future. Luke-Jr was kind enough to starting mining it for us (we sent him a bounty). Hopefully it should be cleared up soon. Apologies again for the trouble and thank you for bearing with us.

Thanks for the update. Glad to hear you are fixing the software.

Strength in numbers

I'm nearly certain coinbase will pay if you pester them. This or something similar has happened twice to Seals players and it has been fixed by coinbase sending new funds.

FWIW one way this may have happened is if they accepted one (or possibly two) confirmations as sufficient to re-use the txout to make another transaction, and then the block that confirmed the tx was orphaned and that tx was not picked up by another miner. The reference Bitcoin client works this way.

Not quite as negligent, but they still should really be waiting at least two confirmations, preferably 3 or more, given they are handling other peoples' money.

This. Very much so.

I will update if anything happens, as well as let you know anything that Coinbase gets back to me with. I'm not an expert with this bitcoin stuff, but there are not any alternative explanations, right?

in any case, don't give up on the 13 BTC, and keep your wallet backups safe

it's possible that a miner could be offered additional financial incentive after the fact, to include an old unconfirmed TX in its next block

in this scenario, coinad should probably be the one to offer the incentive, although stakeholders such as yourself might also volunteer some payment in order to get it processed

willnye,

You can confirm that the following transaction is from coinbase to your wallet, correct?
http://blockchain.info/tx-index/52509782/9eb202978e1653a0d3b1c936c2a07228055ce434c6c065c727336cfc0a74d115

If so, then it doesn't really matter to me why the following output is unconfirmed:
http://blockchain.info/tx-index/52509763/0

The fact that it is unconfirmed means that coinbase should not be using it for customers who are trying to acquire bitcoin. There is simply too much risk of the transaction either never confirming, or ending up part of a double spend. If coinbase wants to take the risk of paying out cash without waiting for confirmations, that's up to them, but they should not be forcing that risk onto their customers.

The person who created that original transaction could re-use the outputs from their transaction and include a nice fee so that a miner confirms it and suddenly the current chain of transactions from those outputs ceases to exist. coinbase isn't out anything, because they already forced the risk onto you. You however are suddenly without your bitcoins. It could happen today, next week, or in a few months.

It looks like you have a chain of a couple unconfirmed transactions there. I'd say that's pretty special and not a good thing.

Woah!! 23kb transaction with only a .0005 fee. No wonder it hasn't confirmed . . .

I agree. coinbase.com should not be accepting transactions like this, and definitely should not be using the output from a transaction like this as the input to a transaction where they are sending someone funds after taking money from their bank account. coinbase.com should not be recommended until/unless they resolve this issue.

If you trace back each of your inputs you come to this transaction that is unconfirmed due to a 0.0005 from CoinAd.

EDIT: This thread was necro-bumped 13 months later on Feb. 28, 2014. This is long since resolved and does not apply to any current bitcoin exchange issues. I'm locking this topic now to prevent further bumps that might lead to confusion among those that don't pay attention to the dates on threads that they are reading.

According to willnye here:

Quote from: willnye on February 12, 2013, 09:06:45 PM

. . . My transaction (http://blockchain.info/tx-index/52509782/9eb202978e1653a0d3b1c936c2a07228055ce434c6c065c727336cfc0a74d115) has been unconfirmed for like 8 hours now and I think I traced the backup to the OPs transaction by using bitcoincharts. I guess there is no recourse right? I just hope I didn't just lose 13btc because of random chance . . .

Quote from: willnye on February 12, 2013, 10:21:11 PM

This was a payment from coinbase to my wallet. I didn't do anything wrong (I don't think)

coinbase.com used this unconfirmed 13 BTC output from this transaction:
http://blockchain.info/tx-index/52509763/0

As an input into this transaction:
http://blockchain.info/tx-index/52509782/9eb202978e1653a0d3b1c936c2a07228055ce434c6c065c727336cfc0a74d115

I certainly wouldn't be comfortable knowing that the currency exchange that I'm using is disbursing funds on unconfirmed outputs, and using them as inputs. Way to much risk of a double spend, or a screwed up transaction that never confirms. I won't be recommending coinbase.com to anyone unless/until they make good on this transaction, and I'd suggest that anyone who currently uses coinbase.com contact them and let them know that you are not happy with this practice.[/size]
