He didn't reached that level of understanding :)

Also note that Phoenix uses electrum, whereas Zeus/Blixt uses Neutrino. The latter offers better privacy.

What is the Difference between How Phoenix and Blockstream Green Do Lightning?

If you want to use those bullshit offers of bolt12 why not just run a CLN node?
Or at least an Alby Hub with LDK backend.

Phoenix yes is a node on your device, but a limited node. I would not consider it a burden. It serve a purpose pretty well.

Blockstream is something else. The node is not in your device, you have only the keys to manage that node that runs on Greenlight infra. It also serve a purpose.

Are 2 different models.
