How do ‘Sphinx’ invoice-less payments on the Lightning Network work?
There was recently a WIP draft published to the
lnd Github, for a ‘Sphinx payment mode’ for Lightning Network nodes. To quote Roasbeef from the Github PR:
Though this is a WIP, it can apparently be used on mainnet already, as long as all nodes involved are upgraded to include the new code.
So how does this work? At a high level, what does the UX look like? At a low level, what differences are there in terms of completing the payment (passing HTLCs around), compared to a standard LN transaction? Whats going on under the hood?
