I should know this since i work on databases, but I assume for mom and pop stores a Nostr database would be efficient enough.
However for people without a Nostr client on their phone, it would be hard to pay. Tho most people paying in Bitcoin also probably have a Nostr client.
Actually, rewards programs like Starbucks kinda seems like a specialized Nostr client.
This all just sounds like yet another way to pay.
I'm trying to gamify getting workers incentivized to have wallets on the phones and accept Bitcoin payments. And gamify stores being happy to have a cheap easy POS. And gamify customers installing this ecosystem.
I'm tired of people not having change for $10s and 20s and what the hell, El Salvador is on the bleeding edge of dedollarizing.
Every 3 pack of pupusas sold for 1 dollar instead of Bitcoin is going to be worth 33 cents in Bitcoin terms in just a few months.
People worry about the price of Bitcoin, but we should worry about the price of the dollar. people are selling things for 1 dollar like it was decreed by God.
