    All lightweight transaction trees in this GenTransactionTree, accompanied by their witnesses and randomness suitable for deriving encryption keys for encrypted view messages.

    All lightweight transaction trees in this GenTransactionTree, accompanied by their witnesses and randomness suitable for deriving encryption keys for encrypted view messages.

    The witnesses are useful for constructing the BCC-style recipient trees for the view messages. The lightweight transaction + BCC scheme requires that, for every non top-level view, the encryption key used to encrypt that view's lightweight transaction tree can be (deterministically) derived from the randomness used for the parent view. This function returns suitable randomness that is derived using a HKDF. For top-level views, the randomness is derived from the provided initial seed.

    All the returned random values have the same length as the provided initial seed. The caller should ensure that the provided randomness is long enough to be used for the default HMAC implementation.
