Onion Message Jamming in the Lightning Network

[erickcestari]

Thanks for explaining further. Two things I want to check before responding:

• This implies forwarding OM only to peers you have a channel.
• Is this reputation a separate metric from the channel-jamming one, or the same score?

And when does an OM cost reputation: only once the upstream peer trips a configured limit, or does every message debit something?

My argument is, if a circuit is broken, the offending node’s reputation should be charged.

@brh28

I contend this attack is not free. The adversary has to do useful work to earn a reputation that is subsequently spent.
