Onion Message Jamming in the Lightning Network

The email delves into the specific mechanics of a reputation system linked with message forwarding among peers within a network. The sender queries whether the reputation metric is distinct from or identical to another score used for channel jamming. Clarification is sought on when exactly the reputation cost is incurred: is it only after an upstream peer exceeds a set threshold, or does each transmitted message carry a reputational cost?

Furthermore, the discussion highlights the consequences of a network breach caused by a node. The sender advocates that if a node disrupts the circuit, it should bear the reputational expenses. This stance is underpinned by the argument that any malicious activity within the network is not without cost to the perpetrator. Essentially, the adversary must initially engage in beneficial activities to accumulate enough reputation, which they then risk losing in conducting any attack. This mechanism ensures that engaging in disruptive actions comes with significant risks, thereby potentially deterring such behaviors.
