Yes, absolutely, I have this in mind as well. Should not be difficult.

Also, with NUT-10/11/14, you can add conditional spend conditions, for example, expiry dates, or, who can spend etc.

That's it, yes.

The user can split the token and send a fraction to someone else.

The token is an IOU redeemable _only_ at the issuing merchant's store for goods and services.

Here's a demo of a decentralised digital voucher system (still WIP) leveraging the Cashu and Nostr open protocols to issue, verify, send, and receive digital vouchers (gift cards).

I started this project with the goal of giving anyone with a Nostr key pair the ability to create and sell vouchers to their customers, for whatever currency they choose.

The voucher is serialised metadata, digitally signed and stored in a Cashu token envelope. It's issued with a negligible sat amount (e.g., 10 sat) paid by the merchant and stored in a NIP-60 compliant wallet.

In the short demo, I play the role of a customer buying a 10k FCFA (fiat) voucher from an existing merchant, and sending 6k to someone else's wallet. The merchant receives the 10k payment (in this case, the sat equivalent) and automatically issues the token (the voucher).

I envision many more use cases to emerge.

Feedback welcome!

Ich war heute wieder in Darmstadt, zum ersten mal nach über 25 Jahren. Da ganz oben rechts wohnte ich.

That's before VAT, lol.

My cashu lib implementation in Java, now public, is part of an ecosystem of multiple projects used primarily for issuing vouchers on nostr.

It's getting increasingly difficult to hide this sad truth.

The article says 10£ per shot, not one pound, as mentioned in your note...

> DragonFire offers a cheaper (£10 per shot compared with, for example, over £1m for a Sea Viper missile)

Ok, just read the article. Toilets etc are ALREADY taxed. The new law will add new items that contribute to increase the comfort of a property, and thus its market value, to justify higher tax property. Maybe we're going back to the window tax after all?

«La taxe foncière repose déjà sur la surface des habitations, mais aussi sur six éléments de confort: raccordement à l’eau et à l’électricité, présence d’une baignoire, d’une douche, d’un lavabo, de WC et d’un chauffage ou climatiseur. Chacun de ces éléments ajoute une superficie fictive au calcul, influençant directement le montant à payer. Par exemple, l’eau courante ajoute 4 m², l’électricité 2 m², la baignoire 5 m² et ainsi de suite.

L'opération de fiabilisation des bases foncières qui va être menée en 2026, dont la réalisation a été arrêtée en concertation avec les associations d'élus, consiste à prendre en compte, pour les logements qui en sont très vraisemblablement dotés au vu des caractéristiques actuelles standards dans les habitations, ces éléments de confort lorsqu'ils ne sont pas aujourd'hui intégrés à la base foncière.»

Au Cameroun, on fait le décompte des votes à la main, et c'est pourquoi il faut en général 15 jours pour déclarer les résultats des élections présidentielles. 🤡

15 jours pendant lesquels une fraude à grande échelle s'opère, rendue possible par une corruption massive des différents acteurs clefs: certains leaders de «l'opposition», la cour constitutionnelle, les responsables des bureaux de vote... Bref, le système semble être verrouillé.

Si jamais ils réussissent encore leur coup cette fois-ci, ce sera reparti pour au moins sept autres interminables années d'extrême supplice...😢

This is the most ideal resting heart rate curve, with the lowest RHR in the middle of the night, which indicates a good night rest. (Exactly what is needed when returning to the fiat mine, after a long vacation!)

"Boko Haram," a djihadist group, inherited most of the weapons given to the Libyan rebels and started destabilising countries in the Sahel region: Cameroon, Nigeria, Tchad, Mali etc.

This is still happening until today...
