📅 Original date posted:2023-03-03
🗒️ Summary of this message: Continuous solutions allow for more precise blocking of attackers and low-reputation nodes. Reporting c truthfully is important to maintain reputation.
📝 Original message:
The benefit is that you can be more precise when blocking. With a binary
solution a single attacker can easily fill your quota of low-confidence
HTLCs and then all low-reputation nodes are blocked. But not all of them
are attackers, some of them just don't send you enough traffic to get a
high reputation for instance and you're going to block them too. With a
continuous solution you can differentiate between an active attacker and
someone who just sends to nodes with poor connectivity and only block the
first.
For reporting c truthfully, if you report it too high you will be penalized
by having your reputation lowered, if you report it too low you will
penalize your HTLCs and still get the same reputation as if you had
reported it truthfully.
