Question about #cashu #ecash: let’s say I run my own mint with LNBits. I’d be the only person using my mint (don’t want to custody other peoples money). So if I send ecash to someone else, it would result in a transaction from my node to whatever node hosts the other party’s mint.
Does this defeat some of the privacy advantages of ecash? Would it make more sense for me to trust someone else’s mint if the alternative is hosting my own for which I’m the only user?

If you send me ecash from your mint, I have to choose to trust you and your mint.
Let us say I accept your ecash and want to exit to lightning then I present the mint a LN invoice, it melts my ecash, finds the sats that back it and pays the invoice with those.
You dont have to exit to lightning or mainnet, but only when you do those actions are node-handled transactions happening. withiin ecash there is no transactions, only minting and melting of blind signatures
Thanks for that. So what I take from this is that there is no privacy benefit to Cashu in the case where I run my own mint, am the only user of that mint, and “cash out” some of my tokens to pay a LN invoice. Because at the end of the day it’s still a lightning transaction from my node where my funds were not commingled with others?
You have privacy within ecash through Chaumian blind signatures, but you lose it if your mint has only one keyset/user as your Lighning anonset is 1 (only one funding LN tx that mints corresponding ecash)
so if you fund a mint, then settle LN invoices using the same mint, it is the same as you just paying LN invoices from your node directly
If you do a multimint swap and then pay the LN invoice from another mint you may gain *some* privacy, but a LN channel connects the two mints so theoretically it is the same privacy as routing payements on LN.
If privacy is the feature you are seeking, I would suggest using trusted mints with more users in it, or set one up witu a group of your trusted friends, and have many unique LN funding and invoice payements interacting with it...
but what do I know, I am just a cat on a keyboard
Makes sense, thank you kitty cat
