1. No. AlbyHub first of all is a private node, not a public one. Secondly, it is done through an Alby account, only the node is self-hosted. So no port fw, no reverse proxy is needed.
  2. You still have to connect it to an alby account, but can be anyone, no need for a standard one (invitation only). Is just one click to connect: https://m.stacker.news/49621
  3. Yes, is still work in progress but is possible to use it like a "hub for many accounts". read more here
Is nice that you can choose many funding sources for the hub: https://m.stacker.news/49622 Only that when you setup the hub, click on "Advanced" mode to be able to select one. By default is going to be hosted on the "cloud", but if you want to self-host on your own hardware and choose a different funding source you must go on "advanced" mode: https://m.stacker.news/49623
  1. and 2) so old custodial alby account / wallet is now split to account and self custodial alby hub. Account communicate with hub over NWC? is my understanding correct?
  2. so If I start using hub now just for my self will be possible used it for my kids later?
later you are trying to say that by default alby hub connect some default LN node in "cloud" but if I want to use "lets say" my LND node I can do it during first configuration in advance setup. IS that default LN node run by alby?

  1. No and yes, depends what do you want to do. For example:
  • if you have an old alby custodial account but you want to migrate it (as is) to a self hosting node, you can link it to your new setup, self-hosted. You can keep same LN address and balance as you had before, only that from now on, you manage it yourself.
  • if you do not have an old ably custodial account, you can create a new one (no need for invitation, invitation is ONLY for those that still want to have a custodial account) and link it to your new hub node (on cloud or self-hosted, it doesn't matter).
  • if you have an old custodial account but you want a new one, only for your new hub self-hosted, you can create a new one and keep it separate from old one. You can even setup with your own domain the LN address or keep it as @getalby.com, as you wish.
  1. Yes, is possible
  2. Yes, you can link it to an existing LND node if you want and act as lndhub with accounts for your family. You can use Zeus, Bluewallet, BitBanana to connect those lndhub accounts. By default Alby Hub is going to run a LDK node (standalone local node), if you do not link it to other source. See the screenshots I posted above.
Indeed, with Alby Hub you have many options. Definitely worth trying it and understand all the features. I think is just the beginning.
