Hierarchical Key Generation #164
Description
Right now we have deterministic key generation using the BIP39 standard for the root key.
However this only allows us to recover the root key. It doesn't allow us to recovery any sub asymmetric keys or any sub symmetric keys.
The HD wallet standard in bitcoin seems to be able to allow us to do this as well, thus the seed phrase can be used to recover all keys asymmetric/symmetric.
This might be useful for recovery.
