    That would happen in an ideal society but at that point you basically have cash. Cash works offline but a digital currency wouldnt because there is no way to prove that youre the one who has the money. This way an offline transaction could be used to basically duolicate money and the first one to reconnect to the network would get the money. But idk, there are much smartee people than me, they can probably figure something out.

      Fully offline is of course impossible. But it can be partially offline. Blockchain, for instance, doesn’t require an internet connection to prove that a transaction is possible, but it does need an internet connection to submit and settle. So you would not need an internet connection to pay, the merchant does to accept payment. Similarly to how this works today with card payments.
