final case class GenTransactionTree extends MerkleTreeInnerNode[GenTransactionTree] with Product with Serializable
A DAML transaction, decomposed into views (cf. ViewDecomposition) and embedded in a Merkle tree. Merkle tree nodes may or may not be blinded. This class is also used to represent transaction view trees and informee trees.

All lightweight transaction trees in this GenTransactionTree, accompanied by their recipients tree that will serve to group session keys to encrypt view messages.
All lightweight transaction trees in this GenTransactionTree, accompanied by their recipients tree that will serve to group session keys to encrypt view messages.
The lightweight transaction + BCC scheme requires that each parent view contains the randomness for all its direct children, allowing it to derive the encryption key and subsequently decrypt those views. By default, the randomness is reused if views share the same recipients tree, and this information is stored in a temporary cache to be used in multiple transactions.
The caller should ensure that the provided randomness is long enough to be used for the default HMAC implementation.
