Hi there!
Is it possible to relate 2 different addresses generated from an HD wallet (both deriving from the same seed phrase)?
I mean, being addr-1 the first generated address and addr-2 the second generated, would it be possible somehow for an external viewer to know that both addresses belong to (or were generated from) the same wallet (same seed phrase)?
My understanding is that it is impossible, by the way key-derivation functions work. But I'd like to confirm my thoughts. Any technical detail is appreciated 
Thank you!

user5406: It's not possible to discover that the addresses are related in any way from the addresses alone. It can however be possible to deduce that addresses are owned by the same entity from how funds received to addresses got spent.
