HD harded key derivation in book “mastering bitcoin 3rd”, at the end of page 115.
There are some discription which i think wrong.
here:
https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch05_wallets.adoc
The resulting “branch” of keys can be used to produce extended
public keys that are not vulnerable because the chain code they contain cannot be
exploited to reveal any private keys for their siblings or parents.
i want to know there are any relation between normal key derivation attack and child chain code? thanks.
