user134631: I have a extended private key, I'm creating multiple child private key / public key pair. If want to verify that the child public is derived from the parent public key. Can I do that? Thanks in advance!

user76567: If you have the parent public key and the (non hardened) index you can generate the child public key and verify that it matches. You can’t do it without the index I’m afraid since the derivation involves a one way hashing step.
