I can import watch-only addresses into my full-node's wallet. I can start querying their utxos from that point onward.
- Where are watch-only addresses stored and how does my node keep index of their balances / utxos?
- If I want to backup and boot a new instance of my node will it retain the indexes associated with my watched addresses?
- Is there a limit to how many addresses I can watch, will many make querying inefficient?
