Based on these mathematical functions, cryptography enables the creation of digital secrets and unforgeable digital signatures.

But more importantly, you would be able to create paper wallets whenever you find yourself in need of a bitcoin paper wallet.

Hardened derivation is therefore used to create a “gap” in the tree above the level where extended public keys are used. The hardened derivation function uses the parent private key to derive the child chain code, instead of the parent public key. This creates a “firewall” in the parent/child sequence, with a chain code that cannot be used to compromise a parent or sibling private key. In bitcoin, most of the data presented to the user is Base58Check-encoded to make it compact, easy to read, and easy to detect errors.
