So, I have been trying to understand the basic functioning of lightning, but cannot connect the theory with the practice. This is what I mean.
Any theoretical introduction starts by assuming two persons, Alice and Bob, want to pay each other without on-chain settlement every time. So they open a channel, put sats that move along the channel etc. Then even if Charlie and Alice want to exchange sats, they can both use existing channels to Bob without opening their own channel etc. Makes sense somewhat intuitively.
But in practice, all I do is use my Aqua wallet to generate an invoice or pay into a merchant’s invoice. I do not see any concept of channel or anything at a user level.
So I need to bridge the gap between these two seemingly different worlds. As an example, supppose I am booking a vacation on Travala and they show me an invoice to pay 800,000 sats. So when I pay using my Aqua wallet, where are the channels and such? Any resource to learn about this?
