Can somebody explains in a simple sentence (subject + verb + object) what's the problem with this attack, besides that can be a possible duplicate for your transaction that never gets accepted by the Blockchain and gets deleted by the Blockchain after 1 week (estimated time)?

There are two problems:

1. Some wallets get confused should they send a transaction that gets changed by the attack, giving wrong status information to the user.

2.  The attacker can increase the size of the memory pool of unconfirmed transactions, which uses extra processing resources, memory resources and network bandwidth, potentially causing sluggish performance of the network and crashing weak nodes.


So: only the weak will suffer.

Thank You for your reply.


Best regards.
