Struct zebra_chain::sapling::ValueCommitment
source · pub struct ValueCommitment(_);Expand description
A Homomorphic Pedersen commitment to the value of a note.
This can be used as an intermediate value in some computations. For the
type actually stored in Spend and Output descriptions, see
[NotSmallOrderValueCommitment].
