Title: Bitcoin Transaction Stuck For 3 Days (Potential DoS Bug) Post by: HasherMe on July 12, 2015, 03:28:08 PM My transaction has been stuck without confirmation for > 3 days.
Yesterday this was stuck and a double spend warning on top: https://blockchain.info/tx/1efea73fc797ae98edcaf9f407742152bd473cef6fbd4376326b330da558e379 Today this is stuck: https://blockchain.info/tx/91f04808fb89a18b08c523cea2037f1ec6372309e5fc21a873a5e6064bb75b0f Somehow the transactions are changing. I own the privatekeys for these 4 wallet addresses involved in the unconfirmed transaction: 1PLoWicvwt4ZQyPXjob1qF5PNwnchfkhR8 1HEEehUwzadonZ62a1bBVknofeqEjG58Kp 1AmirA93DaDaKMsTjWaNdSyiEyU3SVN59C 1Amir1fqsTfbf4XF3CsnnJkPCHrtnhMrTx I used electrum to send the first three transactions and bitcoin-qt for the last (v0.10) on linux. I tried pywallet to remove the transactions. I turned my qt and electrum off for now. Anyone know what is going on? Is there anything I can do to confirm or rollback this tranaction? Since every wallet address I send to gets stuck at unconfirmed, couldn't someone use this as a DOS by sending a small amount of coins to many addresses from one of these corrupt accounts?

This means that the problem lies in TX1 (https://blockchain.info/tx/8e6db292e10cf3e228be8aea7b505d0bb17332d65b1239e2074f0e183fb333f5) and TX2 (https://blockchain.info/tx/f51119ad38643fcdd20a5f211e024a590e8f97ec147846b2b5dd3a3a247633c2). This problem was caused solely by you and not the network. You've included a fee (Fees :0.0001 BTC) less than the recommended one. The rate is 0.0005 BTC per 1K of data consumed by the transaction. (https://en.bitcoin.it/wiki/Transaction_fees)
I think that you should backtrack from the last transaction and start manually deleting. Start by deleting this one (https://blockchain.info/tx/91f04808fb89a18b08c523cea2037f1ec6372309e5fc21a873a5e6064bb75b0f) and then TX2 and then TX1 as mentioned above.

Title: Re: Bitcoin Transaction Stuck For 3 Days Post by: HasherMe on July 12, 2015, 04:37:52 PM Doesn't this give me the ability to spam many other wallet addresses and cause a DoS? All I need to do is send 1 satoshi with a very small transaction fee to many addresses and they will be stuck as well.
Why doesn't the network reject low fee transactions instead of acting so unpredictable? I thought this is a protocol with hard rules. ??? My address with 0.9 BTC has been stuck since last Wednesday (7/8/2015). I really screwed up by sending with a low fee but this might be a potential vulnerability in the Bitcoin protocol. I can infect other addresses with these toxic wallet addresses. Once I send to another address, that address becomes stuck and propogates the issue. I was able to remove the 3 transactions from my Bitcoin Qt wallet. I will let it sit for days or until I don't see the transactions anymore on blockchain.info. |
