I saw "temporary mint" and immediately thought "rug pull".
Your thoughts are precisely why I am against popularity rankings for mints. Popularity contests can be gamed and will get gamed most by those who have most to profit from being on top.
I see mints as ways to manage community funds. Uncle Jim model. My kids will want e-cash cause UTXOs will be too expensive for them early on. Also it's great for privacy.
But how do you keep it to the community / private group that you run the mint for?
That's what I don't grasp yet. I want to run it as a Community Bank.
But if I ask for authentication, I'm a privacy honey pot etc...
How does this compare to running Alby Hub?
thats the thing, it requires you to already have a lightning node.. after which it's very easy to install this in addition.
So let's say:
- I set up a group chat for my normie friends (Uncle Jimming a relay+blossom server for them).
- I run a lightning node (Alby Hub style)
- I run a #cashu mint on top of it
How do I now:
1. only let that private group use the mint?
2. maximize privacy?
Is there some kind of "Proof Of Group Member" that they can share?
Is there a way for me to run the mint in "Blind Mode" or something (and prove it to them!)?
id be interested to know this too

Proof of membership. There is a public member list (in this case that's the relay-based-community list) and you want to prove your npub is part of that list without revealing to the verifier which npub u are.
There is a way to do it by using zero-knowledge sets, however my understanding is limited. It should be similar to (and simpler than?) the work nostr:nprofile1qqsxwkuyle67y94tj378gw8w2xw2wa6nwmwlqhddlwnz0z7sztsaw2qppemhxue69uhkummn9ekx7mp0su9alh is doing (tldr; prove that I own UTXOs that exceed the value of X sats, without revealing with ones)
nostr:npub176p7sup477k5738qhxx0hk2n0cty2k5je5uvalzvkvwmw4tltmeqw7vgup I need that "Proof Of Group Member" we talked about, again 😏
yeah, this idea is super interesting in this context.
Yup, TrEnDiNg mints kinda combines two of the worst things about the internet 🤦♂️
