I wanna say @npub1h2q…w8ch mint is amazing but it seems like they don't like Tor so their mint isn't reachable by this tool. Maybe something they'd reconsider?

2024-10-10 06:52:44

I've built a thing: The Cashu mint Round Robin auditor
An app that perpetually monitors a list of mints by randomly sending Lightning payments between them. Forever. The sats go in a circle until all is lost to fees or rugs. If a mint fails to pay an invoice, it is marked with a scary red label.
You can donate Ecash from any mint to add it to the list of audited mints!

I've been thinking too much about NFC payments lately. It would be insane if we could achive card-to-terminal payments one day but I think challenges with storage and coin selection make the naive approach (store nuts on card, terminal takes them out) infeasible in the short term. However, we can still achieve a lot with phones.
The naive approach with phones would be to send the nuts directly via NFC form device to device. This is possible in Android through Host Card Emulation (HCE) where one phone can pretend to be an NFC card with data on it (the nuts) and the other phone simply scans it. Unfortunately, Apple will never allow us to use their (your!!) hardware for HCE so we shouldn't depend on it.
There is an alternative approach though, which use payment requests. Payment requests are a work-in-progress Cashu NUT protocol update. They are generated by a receiver to tell the sender how to send them nuts. They include information transport methods (how to reach the receiver), optional amount and receiver pubkey. For example, a payment request can say "send 100 sats to this HTTP endpoint, or DM this pubkey on nostr". It can also include instructions to lock the tokens to a pubkey. A payment request can be shared as a QR code, which can be scanned by another cashu wallet that then makes the payment (similar UX like Lightning invoices).
We can use payment requests in combination with NFC to make a very good payment UX that works with Android, iPhones, and on the web (webnfc). If we put a payment request onto an NFC card, that card can be scanned by a sender's phone. The sender's phone could then do the coinselection and send the nuts via nostr to the receiver, for example. This would basically be almost instant. A web wallet like cashu.me could even generate payment requests and store them on an NFC card (from the browser) which another cashu.me wallet could scan (also from the browser) to make a payment. A little bit like a cursed PoS system.
Should be further explored!

It's could be as straightforward as "paste token here" in the beginning. Eventually (I hope soon), we will have NWC for ecash operations and ecash payment requests so that it's more convenient to pay ( @nprofile…le0h is the man here).

That's very interesting, it would indeed be very useful for mints not having to reveal their UTXOs for a proof of reserves. Thanks for noting that.
I haven't been able to look at your protocol yet so I have a rather basic bunch of questions that come to mind:
- The ~55 Mb keyset file you load seems to have information up to a certain block height. Is this file generic for the entire chain or custom to the prover?
- The processing of the file takes quite some time and you mention this can be done once and proofs can be checked faster after that. Does the client need to do the processing or could someone else do it for them?
- Does it require processing custom to the prover or can it be used to prove anyone's claim?
- Is there a window for cheating when the file is for a lower block height than the current one? Since I don't know the UTXOs, is there a way to make sure the coins haven't been moved since the proof was made?
- The range was from 100k to a power of two, you say it's just the way you set it up. Can the range be arbitrarily precise?

Privacy: NIP-60 proposes a new event kind so it would be visible that there's activity. The ecash coins themselves are encrypted but the number of coins (which is visible) *might* allow correlations (realistically speaking, I'm not concerned by this). Example: "Martti seems to have 10 encrypted coins on this relay... I'm guessing that's around 10000 sats but who knows, could be 10, could be a million".
It might make sense to use a different key pair for NIP-60 that's derived from your OG keys, but that would be harder to agree on.
NIP-61 is about using these ecash coins for zaps so the whole idea there is to be public.

cashu.me is still far from being NIP-60 ready. There are code bases you can have a look at, probably the simplest one being nutsack.me - @nprofile…qdrm's NDK will/does support NIP-60 wallets afaik. We use NDK in cashu.me as well.

We had a Cashu dev call yesterday and four (!!) new wallets based on NIP-60 were presented. NIP-60 is a standard for storing ecash on no:str relays, encrypted with your keys.
You open a wallet for the first time, login with your nsec, and boom, your balance appears.
Don't like this wallet? Switch to another one, enter your nsec, and your ecash appears there too.
This is pretty insane. If you're building a wallet, you're immediately plugged in into a social net. Now you can also carry your money around from app to app, or website to website.
If you're a Cashu dev, you should join our monthly open dev calls. Hit me up!

Another cool part: the universe is expanding. That means the thing you're looking at is moving away from you as you're looking at it. The speed at which it moves away increases the further it is away from you (like a dough expanding in the oven, you're the raisin in the bread). But the speed of light is constant. So combining these two facts, it means there are things that are so far away that they move faster away from us than the light they can emit to reach us, which means their light never reaches us. Never.
It's your (personal) edge of the universe.

Spent time with a bunch of good Bitcoiner friends. Most of them don't use nostr. All of them urged to explain why they don't without being asked to do so. An indication of a bad conscience, I guess that's good for nostr but it doesn't really matter. Anyway, what's their reason? They haven't seen nostr used for much more than "just social media".
Obviously, they're retarded and wrong and I love them. But that doesn't matter either. They don't know that the most exciting use cases of nostr are beyond a Twitter clone and it seems that that's what would make them reconsider it, but I don't believe them really. I think they don't care and made up a bunch of nonsense excuses because they feel the social pressure from their Bitcoiner peers.
