App idea: Uber but all payments are made with Cashu, journeys are published in Nostr, and a review system based in Nostr. The driver could set a desired €/km and the user could make offers.
Obviously it'd not work:
- network effects
- the regulator of each country will punish drivers (taxi cartel)
- the mainstream don't use BTC already...
But sounds not so difficult to implement, I'd be concerned about privacy because one would be publishing its routes on Nostr 😓
