warning out of the way, this is the best implementation of this terrible idea I've seen so far: https://offline.cash
In offline e-cash, you still need an online mint to initially create and validate tokens. The mint provides the cryptographic signatures that make the tokens valid. When you go offline, you carry pre-signed tokens of various denominations. These tokens can be exchanged directly without real-time verification from the mint, but the mint must have originally signed and authorized those specific tokens. So "offline" really means peer-to-peer exchange using pre-validated tokens, but the initial token creation and validation still requires an online mint.
Are we overloading the word "offline"? Surely the LN payment eventually needs to reach the online LN eventually?
