\subsection{Arithmetic problems}
This section lists cases where the arithmetic of the exchange
involving amounts disagrees with the arithmetic of the auditor.
Disagreements imply that either the exchange made a loss (sending out
too much money), or screwed a customer (and thus at least needs to fix
the financial damage done to the customer).

TODO.
This section lists cases where the exchange made arithmetic errors found when
looking at the transaction history of a coin. The totals sum up the differences
in amounts that matter for profit/loss calculations of the exchange. When an
exchange merely shifted money from customers to merchants (or vice versa) without
any effects on its own balance, those entries are excluded from the total.

This section lists operations that the exchange performed, but for
which the signatures provided are invalid. Hence the operations were
invalid and the amount involved should be considered lost.
The key given is always the key for which the signature verification
step failed. This is the reserve public key for ``withdraw''
operations, the coin public key for ``deposit'' and ``melt''
operations, the merchant's public key for ``melt'' operations,
the (hash of the) denomination public key for
``payback-verify'' and ``deposit-verify'' operations, and the master
public key for ``payback-master'' operations.
