Kind of incomplete question. There are many types of nodes and I explained them in many of my guides.
Seems that many people still do not know them and I will try to list them here, because are many differences:
  1. Main Bitcoin Core nodes
  • Just running a Bitcoin Core on a simple PC, for personal use, with limited connections
  • Running a public Core node with more than 10 outbound connections, good bandwidth, stable that will serve for many other small nodes to sync
  1. Core + LN nodes
  • PUBLIC routing nodes
  • LN banks, kind of mixed public and private LN node, serving multiple users
  • LSP kind of LN bank serving liquidity for private users and routing it to public channels
  • PRIVATE non-routing nodes
a. desktop private nodes b. mobile private nodes
I've explained the LN topology here: #486306 Do you want me to enter in more details from here ? OK but first please read all the guides I wrote about nodes: https://darth-coin.github.io/nodes/nodes.html
