So I have also written a tool specifically for merchants that need to request a payment of a certain amount of sats. Basically what it does is:
* Read the card
* Receive the token -> generates fresh coins
* Split the fresh coins in amount to keep and change
* Try and flash the change to the card
- if that fails, print a qr code with the change to the screen instead.

2024-10-04 11:05:20

- reply

well the cards i am using here are 1Kb. It works if the number of coins is small. So if you flash, for example, 128 sats (1 coin) works fine. But if you flash 127 sats (7 coins) it will fail.

The idea of an ecash credit card that you can just swipe and pay with is very tantalizing.
The only real problem? A savvy merchant could record all your unspent secrets and spend them later if you forget to swap them back.

Idk what it could look like with nostr. initially I thought the authority could be the municipality or the district where you go to vote, which would verify your identity before signing your blinded ballot.
The benefit of this is mainly the assurance that your vote is anonymous and that each vote that is cast is surely signed by someone within the public keys set (for example a foreigner cannot vote)

2024-09-05 19:09:19

I am wondering if a digital voting scheme would be possible by combining ring signatures, blind signatures and nostr.
With ring signatures a voter can sign their vote anonymously, and anybody can verify that "someone" that is registered as a voter has cast a valid vote.
The problem with this is that a voter can cast multiple valid votes, while we'd want to constrain that to one.
If everybody votes the cheating can be spotted, because the votes would surpass the number of voters. But even then, it would not possible to distinguish which votes are duplicate.
If we introduce and authority figure, then we can use blind signatures.
A voter creates their vote, turns it into a number, blinds that number and then communicates it to the authority.
The authority only signs that blinded vote if it can confirm the identity of the voter and that it hasn't already cast a vote.
The voter can then unblind the vote (only they can do that) and create a ring signature of the vote with the public keys of other plausible voters.
Now I am thinking: could we split that authority amongst nostr relays and have it collaboratively blindly sign something?

* Don't even bother publishing proof of reserves?

2024-08-27 22:15:52

- reply

I do not agree.
Dismissing this problem as one that will fix itself is kinda naive to me.
Bitcoin nodes basically only do one thing: validate blocks. That's why anybody can run them. That's why the decentralization works. They require low processing power, low space. People don't need an incentive to run them (hell I ran one on a 13 year old PC with a Pentium and some additional HDD slapped on)
Nostr relays don't have a set limit to their applications (literally "AND OTHER STUFF"). Basically, they could be doing anything at one point. Especially with the pace at which things are developing.
Right now people run relays because they like to and they might even be relatively cheap (I don't know), but at some point it might become so burdensome that they would need a revenue model. And few people will use paid relays.
You could end up with a situation like Tor, where 2/3 of the network is in the hands of three letter agencies that don't mind doing all kinds of nasty shit.
Anyway, just my opinion. I hope I am proven wrong.

2024-08-18 22:09:57

With cashu there's always been a dilemma when sending ecash to someone: did they claim the payment?
Sure a wallet can ask the mint if a certain set of tokens were spent, but that creates a link between the sending and receiving wallet. It's a leak of information that loses you privacy.
A first solution, although maybe impractical, would be to let the mint stream the information about all the spent tokens to clients that request them (through apposite WebSocket endpoints).
So If I am a wallet and I have just sent some e-cash to someone, I can connect to the mint and "listen" until I am satisfied (until I know the e-cash was claimed).
This could put some pressure on the mint and it's not clear to me if it could be used to perform some DoS attack.
A better approach could leverage Nostr!
A mint with that advertises its associated `npub` on the `/v1/info` API endpoint could then regularly publish notes with all the information about freshly spent e-cash.
Clients would just have to query for notes with a `p` tag referencing the `npub` of the mint and look for the e-cash they just sent. Easy.

Nope cashu is single custodian.
But if people are gonna be hooked on stablecoins for convenience and price "safety", then they might as well get hooked on USD e-cash, instead of Tether.
You get more privacy, basically free transactions and when you redeem, you get an equivalent amount of sats.

With Cashu we'll soon have USD e-cash backed by perpetual futures short BTC (on platforms like LNMarkets), instead of treasury notes or real cash.
Would you or your people be interested in using this instead of tether?
Not to mention this would also spread bitcoin adoption because these tokens can only be redeemed for an equivalent amount in sats, over lightning.
