Title: [HELP] Sent a transaction with 30sat/B, increased the fee now Double Spend Post by: jpoker272727 on July 05, 2017, 07:47:08 PM I'm having issue with Electrum
Sent a transaction with 30sat/B but is taking too long, then increased the fee (Replaceable) but still not confirmed. Now blockchain doesn't recognize the new tx id, when I checked in blocktrain it shows the first one as Double spend and the second (new) one as "OPT-IN RBF" Is everything going right or I'm missing something!! Thank you...

I'm worried because I'm making a transaction to a platform that has a bitgo or something like this and I am afraid that is not counting the second transaction as a valid one until the first one gets cleared.

Just wait a few days (usually 3 or 4 days) and the transaction will end up getting dropped from the mempool just like it never existed.Title: Re: [HELP] Sent a transaction with 30sat/B, increased the fee now Double Spend Post by: pooya87 on July 06, 2017, 02:54:57 AM first of all an RBF transaction is a kind of double spend, because you are practically creating a new transaction and it doesn't matter that you are spending the same output and sending to the same key.
secondly not all bitcoin nodes have implemented RBF or accept these transactions. some of them will reject it as a double spend and so they will keep the first one in their mempool until it becomes invalid. thirdly i believe from what you said your first transaction was not an RBF transaction. the first one needs to be and RBF transaction so that you create a new one that easily replaces it with a higher fee. if you haven't then that means you are simply double spending and it doesn't matter if you only mark the second one as "replaceable".

There is nothing to worry about.

Thank you very much pooya87, I learned new things about double spend, and the electrum did a perfect job. I didn't know that we can "extend" the transaction to another one, after the first confirmation it got listed in blockchain.info |
