user63374: Hello I have a lot of derived public keys and derivation path to them how can I get root public key which was used to generate this pub keys?

user48884: You cannot. It is impossible to get the parent public key from the child public keys. This is because a hashing algorithm is used in deriving the child keys and hashing algorithms are not reversible.
