Is this new Amboss function as hazardous as it appears? The analytics firm unveiled “Reported Channel Balances” and the bitcoin planet straight away reacted with serious criticism. Were they overreacting or did they have a point? Is bitcoin’s Lightning Network at danger? Let’s study precisely what occurred and discover out. It all begins with the notion that a node’s capacity is not the very same as a node’s liquidity.
We’ve also offered node operators the potential to share and analyze their node status, which includes channel balances. This will let us to provide improved insights, notifications, and valuations for bought channels. pic.twitter.com/YgJmxFokS8

In the medium post announcing the “Reported Channel Balances” function, Amboss expands on the thought:
“One major piece of information that has been missing since the beginning of the lightning network is the difference between lightning’s capacity and its liquidity. To find the difference, we need a piece of information that (thankfully) is private by default: channel balances.”
Since that is nonetheless a crucial piece of data, several actors discover out channel balances by working with the probing approach, “which is an attempted payment designed to fail, reveals private information about channel balances without consent. It is, in a way, an attack on the privacy of nodes.” So, Amboss knows that the Lightning Network’s privacy is at stake. The sender’s funds are also a stake, considering the fact that they “may get locked, temporarily.” And it is even worst for the target.
Amboss’ Idea: Reported Channel Balances
So, to phase out probing, Amboss enabled a way for nodes to voluntarily report their balances. “we’ve created a single endpoint that users can send this data to and it will be displayed on the node’s Amboss page.” There’s the possibility of sharing the information just with Amboss, but nodes can go public with their data if they want. “The settings span from Private (shared only to Amboss), Range (balance shown publicly as 25%, 50%, or 75%), or Public (the specific percentage is shown to Amboss visitors).”
In basic, the thought behind the function appears a tiny naive, and nowhere is that additional evident than in the way they’ll treat lying nodes. “In truth, anyone can write a script to lie about their balances. Instead of trying to rout out the liars from our data set, we’ll try a different approach: deliver services based solely on the information we’re told.” The Amboss folks took “kill them with kindness” to a new level.
“We’re building tools to help node operators whether it be through providing notifications and alerts or through providing insights that help users make good decisions with their nodes. The best way that we can help is if users are sharing their balances honestly.”
So, the incentive to be truthful is the useful information that Amboss will give you? Sounds frail.

The Case Against Reporting Channel Balances
Lightning developer Openoms, whose twitter bio says “Building nodes for Security, Privacy and Freedom,” lead the charge against Amboss’ new self-policing function. “If this data sharing and aggregation by Amboss gets widespread and accurate we’ll have a huge problem with Lightning privacy.” He also supplied options, doable guidelines, and a clear course of action. “Good it is open-source, let’s make it not possible to share more than 2 bits of data.”
Some mitigations for now:
cannot genuinely inform if somebody is sharing privately, nonetheless:
* never peer with sharing nodes
* stay clear of paying by way of sharing nodes
* appear out for CLN peers who cannot run Thunderhub
* feed it random information if something
* use aggressive MPP and longer routes

Openoms also breaks the currently frail logic behind the function and poses that as an alternative of producing “data sharing the norm because probing is already possible” we should really “make probing more difficult, expensive and inconclusive.” As for the actionable products, Openoms presents “some mitigations for now:”
- “Don’t peer with sharing nodes”
- “Avoid paying through sharing nodes”
- “Look out for CLN peers who can’t run Thunderhub”
- “Feed it random data if anything”
- “Use aggressive MPP and longer routes”
How did Amboss react to the criticism?
Amboss’ Quick Response
Say what you will about the analytics firm, but their response was cool, calm, and collected. “We sincerely appreciate all of the feedback (even if it’s negative) with respect to our channel balance sharing feature,” Amboss tweeted. Then, they gave credit exactly where credit was due. “Special shout out to Tony Giorgio & Openoms who’ve provided valuable insight on serving our users while preserving network-level transaction privacy.” Amboss also clarified that the function is opt-in and comes disabled by default.
One crucial reality to get ideal amidst the controversy: The @thunderhubio style is OPT-IN only and private by default.
Thunderhub is a user-friendly MIT-Licensed node manager that respects the user’s selections.

Before we go, we have to discover out what did Tony Giorgio say that was so insightful. He led the discussion in the phenomenal Stacker News, and began the fire by writing:
“We do so much to try to protect the privacy of the lightning network but always going to be constantly fighting the tendencies for society to give away information for convenience. I can’t begin to tell you how aggregating this information to a single party is an attack on Lightning and the privacy of all individuals as a whole.”
Sweet, old comfort. How considerably problems have you led humanity into?
