A positive $\balancingValue$ takes value from the \transparentValuePool.
A negative $\balancingValue$ adds value to the \transparentValuePool.
As a result, positive $\vBalance$ is treated like an \emph{output} value,

A positive $\balancingValue$ takes value from the \saplingValuePool and adds it

As a result, positive $\vBalance$ is treated like an \emph{input} to the

from that pool.
Consistency of $\vBalance$ with the \valueCommitments in \spendDescriptions
and \outputDescriptions is enforced by the \bindingSignature. This signature
