Title: Congestion Attacks in Payment Channel Networks Post by: ABCbits on February 18, 2020, 01:42:52 PM I was looking for few papers on arXiv and found very interesting paper with title "Congestion Attacks in Payment Channel Networks"[1] and just submitted 2 days ago.
They mention 2 possible attack which are : 1. Attacking whole network by relaying a transaction to the attacker himself. Surprisingly, similar method is suggested to improve user's privacy[2] 2. Isolate a single node/hub by creating multiple payment request through attacked node/hub (i don't really understand this part) What do you think?

It may worth a read, I don't know, I still didn't completely understand it.
