55 sats \ 2 replies \ @senf 9h \ on: What Happens to transaction in a 'reorg' ? bitcoin
Yeah, that's right. I have no idea about Monero, but with Bitcoin the transactions can still end up in a block if the input UTXOs haven't been changed. If a person has paid and received their goods and sees that this has happened, they could RBF and send the sats back to themselves.
i see, and so the reorg attacker would spend their coins, do the reorg attack, and then if successful, be able to spend them again. Thus, the reason for a reorg attack is to be able to spend your money more than once...so the attacker needs to be coordinating the reorg with their own spends. Any other benefits to an attacker ?

That's right.
Any other benefits to an attacker?
They would also come in as the miner with all the new blocks, so they'd have the block rewards associated with those blocks involved in the reorg. They would have been able to do that or something close to it with honest mining too, so I'm not sure that would count as a benefit.
