Hi all,
My understanding of the local reputation channel is the following, when Bob
receives a HTLC forwarding request from Alice to Caroll:
- if Alice has reputation of 1 and Alice endorses the transaction, Bob
forwards and endorses the HTLC to Caroll
- else if the HTLC amount is under the
Hi all,
Sorry if I jump in the middle of the party!

I completly agree! Why we will not propose an practical definition of the

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
Could you explain the benefits of continuous solutions over binary? This is
something we should definitely understand before going in a more
complicated direction.
Also, I'm still not sure that the rational behaviour is to report *c*
truthfully.

By giving a high confidence to HTLCs you increase the chance that they are
relayed which should be your goal. Having a high reputation is not a goal
in itself, it's just a way to make your HTLCs more likely to be relayed. If
you always report confidence 0, then yes you will have a reputation of 1
Hi Thomas,
Thanks for the example.

Is there anything to gain from giving high confidence? By doing this, you
risk lowering your
To give a very simple example, imagine a node that sends the same
confidence c for all HTLCs. We want c to be equal to the probability p that
its HTLCs succeed.
- If c = p then all is well and we give a reputation of 1 to the node.
- If c > p then this node is overconfident or is lying to have its
Hi Thomas,
I really like the idea of taking into consideration the failures. In our
proposal, a failure won't benefit your reputation, as the neighbour is
trying to reach a fee threshold, but taking it into account instead of
ignoring it could be helpful against an adversary trying to manipulate
Hello,
I think the local reputation is more important than upfront fees and should
be worked on first because 1) the most likely attack against the network
today is the slow jamming attack against which upfront fees are not very
effective (an attacker would only consider fast jamming if the
Hi List,
We’re writing to seek early feedback on a draft for a neighbour reputation
setting recommendation as a jamming mitigation. The main idea is that
allowing full access to liquidity and slots in a channel can result in
jamming. To prevent this, we allow full access only to neighbours that
