+\section{Criteria}
+
+\begin{itemize}
+  \item \textbf{Cryptographic Assumptions.}  This needs to be included 
+    and needs to contain more than just ROM because some schemes advertise that
+    they don't need ROM but rely on some other rather strong assumptions.
+  \item \textbf{Refunds.}
+  \item \textbf{Offline Spending.}  Causes brittleness, not a goal.
+  \item \textbf{Exculpability When Restoring From Backup}.  Usually conflicts with offline double spending detection.
+  \item \textbf{Traceability.} Means that (a threshold of) authorities can deanonymize a customer
+    if required (e.g. to catch a criminal).
+  \item \textbf{Transferability.}.  Ability to transfer a coin from one user to another.
+  \item \textbf{Taxability / Income Transparency.}  E-Cash can't be reliably transferred
+    without the transaction being recorded at the exchange.
+  \item \textbf{Time/Storage for Deposit.}  Often not considered, especially
+    in ``constant time'' schemes.
+  \item \textbf{Time/Storage for Withdrawal.}
+  \item \textbf{Divisibility/Change.}.
+  \item \textbf{Robust Spending.}  The customer either can prove that they payed for
+    a contract, or they can get their (unlinkable) money back.
+  \item \textbf{Provably Secure.}
+  \item \textbf{Endorsed (??).}  Separation of the coin and permission to spend
+    it, see \cite{camenisch2007endorsed}.  Allows fair exchange (?).
