 Random data that allows us to extend a key. Without this, we can't figure out the next key in the chain and
 should just treat it as a regular ORIGINAL type key.

 and high bit unset for public derivation.

hasIssuedSubkeys

public boolean hasIssuedSubkeys()

 How many children of this key have been issued, that is, given to the user when they requested a fresh key?
 For the parents of keys being handed out, this is always less than the true number of children: the difference is
 called the lookahead zone. These keys are put into Bloom filters so we can spot transactions made by clones of
 this wallet - for instance when restoring from backup or if the seed was shared between devices.
 If this field is missing it means we're not issuing subkeys of this key to users.

hasSigsRequiredToSpend

public boolean hasSigsRequiredToSpend()

 Number of signatures required to spend. This field is needed only for married keychains to reconstruct KeyChain
