Oddbean new post about login | logout But you can zap someone with Lightning when they are offline too, no? I wake up and have new zaps in my wallet. I didnt have to accept them.
He's talking about the node. If the node is out of reach for some reason he can give you the token and you will redeem it when it's back up. Example you go to a store to pay, the store LN service is down or the store has no net, the store might accept the ecash and redeem it when it gets online again.
