I apologize for the bump, but this has been done Cool
There’s also a good (albeit too detailed for the average consumer) explanation of how it works in the video.

How does the protection against double-spending work?

Why doesn’t someone who wants to operate vending machines also operate a mining rig that specifically prioritizes confirms from transactions from it’s vending machines?  This way, it could release the goods immediately from receiving the btc and then expedite the confirmations thus minimizing risk of double spends.

why doesnt someone that wants to operate vending machine have a small service where people put in pocket amount of funds in per day while taking a shower in the morning EG 0.1BTC which get pre confirmed into the service. then the funds are ready to use throughout the day

and the balance is deducted when they scan qr codes from the vending machine.

then they can expand this pocket money service to also cater to a payment gateway for starbucks, 7-11 etc..

i wouldnt call it a bank i would call it more like a prepaid service. much like how people use oyster cards in london to pay for train tickets and other things.

You just described green addresses.

i think it is the solution to those kind of problem.

Otherwise i’ll allways be able to give my private adress to 10 friends buy a snack, send a txt to them and they all go to buy a snack with the same private adress. If i send the txt message before buying the snack i can even get poeple using that private adress in china at the very same moment i use it in london so it might be very hard to be instant AND secure without green address.
