Thanks for producing this davout, these is a great need for an iso wallet. Can I ask if both sender and receiver need Paytunia for this to work? I was not quite sure from the description.
Transfers are instant between Paytunia users, if you receive money from the Bitcoin network you will have to wait for two confirmations.
Are my bitcoins stored on my phone or on a server somewhere? Does this make a wallet.dat file on my phone, or am I making an online bank account with bitcoins in it?
Bitcoins are stored in Paytunia's hosted wallet, which contains only a small fraction of the deposits. Your phone is a lightweight client consuming our
API, which is compatible with the Bitcoin-Central.net API.
There already exists an iOS app that act as a full Bitcoin node, but we think that's overkill given the limited storage amount and network connectivity of such an iPhone.
Paytunia does not require 1G+ free space, doesn't take more than a few seconds to get started with, and will notify you of balance updates whether you're on Wifi, 3G, or regular network. Oh, and it's gonna be free too !
