Struct zebra_chain::sapling::NotSmallOrderValueCommitment

source · 
pub struct NotSmallOrderValueCommitment(/* private fields */);
Expand description

A Homomorphic Pedersen commitment to the value of a note, used in Spend and Output descriptions.

Elements that are of small order are not allowed. This is a separate consensus rule and not intrinsic of value commitments; which is why this type exists.

This is denoted by cv in the specification.
