Hi, artist here.
I want to use the moment of attention to ask around for ideas on how to conceptually build the reverse of this. The current idea would be to also use a web wallet, ie. you would preload an easywallet.org wallet with some coins, then give the URL to the machine (type, QR, whatever) and it spits out cash. There must be something more clever to solve the problem of transaction verification (inside easywallet it's instant and we don't have to wait 10m) and authentication (if the machine would receive your bitcoins on a special address, how the machine know you sent it?).
- tomflack 14y agoThere are NFC bitcoin wallet apps for android aren't there? And "POS" NFC apps? Just cram an android board and an NFC reader in it set to accept taps, look up the exchange rate and spit out cash.
- 178 14y agoNFC has 0 users in my area, so later on this would be an option. But what about something right now, not involving complicated tech?
- tomflack 14y agoBitcoin probably has less users in your area than people with NFC capable phones. I think for an art project this is a non-issue. I also think if you consider my solution so "complicated tech" then this probably isn't the project for you.
- gwillen 14y agoYou would probably have to give people a unique address to send coins to, along with a corresponding secret code to use for their withdrawal.
- aristus 14y agoAs an aside, how do you generate the QR code? Do you have to create a separate wallet?
- 178 14y agoThe value of 1€ is stored in a seperate wallet. The QR code is the link to the URL of this web wallet.
