What are the privacy implications of spending btc via ecash like Cashu?

Im early in my exploration but have extensive experience as a routing node operator.

Id imagine that in this scenario you are only as strong as your weakest link, which in this case is lightning. For example, spending of ecash across mints requires liquidity on lightning, and is only as private as we can assume lightning, limited by publicly created channel liquidity and potential man in the middle attacks whereby a well connected routing node may also function to surveil the network flows.

Can I assume the closest we get to perfect privacy with Cashu is when spending WITHIN the mint, where our anonymity set is infinite among other network users, and equal to the pool of participants using the mint, when viewed from the mint operator's perspective?

If these discussions are occurring or have occurred elsewhere Id appreciate any info.

Boosted to get your name out there

we all need a good boost from time to time.

Ive got some.more sats for the next 10 minutes if anyone else is hungry.

Boosted and followed thank you ser ๐Ÿ™

Hungry? Starving.

Appreciate all who participated in my morning marketing test. Now only zapping for content ๐Ÿ˜Š

Ill post some results this evening for those interested.

Done, but late to the game! No worries! Welcome to NOSTR!

done because I need to learn more about this

Yep. I built a lightning payment system where payments are cleared via a mint and settled via Lightning. If the payer and payee use the same mint, the clearing is done directly via the mint and does not even touch lightning.

๐Ÿ™๐Ÿ™ this is powerful tech

Itโ€™s been almost two years to the day that I discovered Cashu. It supercharged my learning curve, and now I am building my own wallet that works completely on nostr.

so happy to have found you and look forward to collaborating and supporting your work

Boosted it as soon as I saw it ๐Ÿค™

Hope it helps spreading the message

Thank you!

Havent run into 'boosts' yet but you are the second to mention. Thank you!

Privacy and anonymity is always down to the side of the crowd you are hiding in.

If you are in a mint of 10,000 people and you make an internal payment all that can be seen (even by mint operator) is that one of 10,000 has made a payment to one other. Or perhaps they just swapped some notes!

This can be degraded based on networking considerations or if particular scripts are used that might leak other info.

In terms of lightning the privacy you would see something similar. I.e one of 10,000 people has paid a lightning invoice but you wouldnโ€™t know who.

Hope that helps.

What about multiple mints, with few users but only on onion net based on only onion LN nodes? Users could be protected but also mints should be .. the easy thing to shot down a mint is find its owner and point an fire arm in the head and asked him to stop running it .. but what if mints are many and without owner as is as their LN nodes?

sounds similar to fedimint protocol
