A public node in a Hierarchical Deterministic (HD) key tree.
Note, HD nodes are network-independent. A network is required only when encoding the node as an HD key or using a derived public key in an address.
32 bytes of additional entropy which can be used to derive HD child nodes.
The child index at which this node is derived from its parent node

0x80000000 use the "hardened" derivation algorithm. The maximum
In BIP32 HD derivation paths, hardened indexes are usually represented by
subtracting the hardened index offset (
2147483648) and appending
the child index number. E.g.

The first 4 bytes of the parent node's identifier. This is used to quickly
identify the parent node in data structures, but collisions can occur. To
resolve collisions, use the full parent identifer. (See
deriveHdPublicNodeIdentifier for details.)
The full identifer of the parent node. This can be used to resolve
collisions where two possible parent nodes share a
Since the full
parentIdentifier is not encoded in BIP32 HD keys, it
might be unknown.
