 Reference: \cite{okamoto1995efficient}.  Efficient construction for divisible E-Cash, but multiple independent
 transactions with the same coin are linkable.
 
+\subsection{Electronic Cash with Change Return}
+Reference: \cite{tracz2001}.  Has change return, but not with the same taxability guarantees as Taler.  Also has an implementation.

 $2^\ell$ coins must be spent at once, or all coins must be spent separately.
