pub struct SerializedTree(_);
Expand description

A serialized Sapling note commitment tree.

The format of the serialized data is compatible with CommitmentTree from librustzcash and not with [Frontier] from the crate [incrementalmerkletree]. Zebra follows the former format in order to stay consistent with zcashd in RPCs. Note that NoteCommitmentTree itself is represented as [Frontier].

The formats are semantically equivalent. The primary difference between them is that in [Frontier], the vector of parents is dense (we know where the gaps are from the position of the leaf in the overall tree); whereas in CommitmentTree, the vector of parent hashes is sparse with None values in the gaps.

The sparse format, used in this implementation, allows representing invalid commitment trees while the dense format allows representing only valid commitment trees.

It is likely that the dense format will be used in future RPCs, in which case the current implementation will have to change and use the format compatible with [Frontier] instead.
