I’ve 5 Regtest examples: (h4, h3, h2, h1, h0), all utilizing the identical xpriv (Regtest), however at totally different ranges of hardening from completely hardened to Utterly unhardened. The key/wif are derived at index 0.
I wish to perceive the (mother or father Xpub + little one secret) => (Mother or father Xpriv) state of affairs a little bit extra concretely by examples.
From this information (h4 to h0), which of those circumstances would compromise the xprv/tprv?
Additionally, how simple is that this, would somebody have the ability to submit the xprv/tprv right here to show?
