[umarkah]

Hello all . I am a new bitcoin user and today i sent 0.001btc to this adress 1BGd2NgvQhGz6wQDeuKtjj3EPzi2wd6gnK from my bitcoin core wallet. After a while When i went to https://blockchain.info/address/1BGd2NgvQhGz6wQDeuKtjj3EPzi2wd6gnK?filter=7 to have a look at my transaction i saw 2 transactions of 0.001btc instead of one . And when i clicked on the both of them stated this error
Warning! this transaction is a double spend. You should be extremely careful when trusting any transactions to/from this sender.
I also made another transection of 0.0012 yesterday that still needs to confirm but i dont know where did the third one come from
Please help me solve this issue I have no idea whats wrong here im just a newbie please help and thanks in advance.

there are still some attacks on the network, where bad people forward your transaction with a different tx id trough the network (malleability attack), this caused the "error" you are seeing on blockchain.info.

You bitcoin client (core in that case) should sort this out after a few new blocks. (So just wait for more conformation as one of the tx will be dropped if the other will stay).

If it won't sort out itself you can perhaps also try to -rescan your wallet.

Hope that helps

Shouldn't the Bitcoin Core's latest version which was patched for this sort of attack stop this? Or maybe OP is using the older version Bitcoin Core.

Which version are you using OP?

And if you notice the two transactions they have different fees. It's not possible for the attacker to change the fees, the first one has a very low fees. I don't think this was the malleability attack. But can't say what happened.

It should be patched and nodes with the latest client would not relay it and consider it non standard. Anyway, I believe -zapwallettx works too.

To my understanding:
You initiated this transaction first: https://blockchain.info/tx/64447ecaad274a2d4edb7e9716f4dbf1cc8a871bd29ac815497968dde91f6234
The next day, you initiated this transaction: https://blockchain.info/tx/a15f81a67cb3b990ab89c36a15348db66ab8f39c6007e4c9ed6b8631eb936fe7
And this transaction: https://blockchain.info/tx/c471d60bece79ffad8cb5230d3dd80da1b351b3a3a21c054b490b59193880d7a.

The first two transaction will not confirm because the third transaction has already confirmed. They are definitely not malleability attack since all of them have different fees.
