The p2p nature of transactions broadcasting
I am talking about rebroadcasting. And rebroadcasting logic behaves differently for cases:
- you are the owner of public key (even if only on receiving site)
- you are not the owner of public key
And any externally visible difference for those two cases can be leveraged to deanonymize users.
reasonable to say that the node that you see as the broadcaster to you of the transaction is not the creator of the transaction.
And that's why I pointed out the 'repeatable rebroadcast' part. Single measurements obviously won't reveal the owner. But repeated measurements over time will do it faster than you would expect.
How is rebroadcasting different from broadcasting in the p2p network?
Can you point to some resources?
Never said it is different. Rebroadcasting means repeated broadcasting.
And the "repeating tx broadcasting forever (because of low feerate)" part is privacy compromising. Hope that helps clear things up. For more info just google "bitcoin rebroadcasting".
How is it compromising if you rebroadcast repetedly any tx in the mempool? What exactly does it compromise? It gives out the information that you have a mempool that holds transactions longer than the median holding time of the network, that's it. That tx is possibly not yours.

IP address to all peers.

Yeah, unless you wait for 2 weeks (or whatever the default eviction mempool policy is) after which the transaction rebroadcasting links it to your IP. I repeat again. Bitcoin core treats those transaction as your own when your pubkey is the receipient. And will not stop trying to rebroadcast them.

Wtf? The p2p nature of transactions broadcasting is not an attack, it'simply how a p2p network works. Since things are as such, the logical conclusion is that basically you can never assume that the creator of the transaction is the one who broadcasts it. Or better, it's reasonable to say that the node that you see as the broadcaster to you of the transaction is not the creator of the transaction.
