The balance of the escrow account should

be {\bf {{ data.total_escrow_balance }}}.

This section analyzes the income of the exchange operator from fees.

\section{Lag}
|
|
|
|
This section analyzes the lag, which is by how much the exchange's aggregator is behind in
|
|
making wire transfers that have been due.
|
|
|
|
The total amount the exchange currently lags behind is
|
|
{\bf {{ wire.total_amount_lag }}}.
|
|
|
|
Note that some lag is perfectly normal, as tiny amounts that are too small to be wired
|
|
are deferred beyond the due date, hoping that additional transfers will push them above
|
|
the tiny threshold. Below, we report {\em non-tiny} wire transfers that are lagging behind.
|

\section{Deposit confirmation lag}
|
|
|
|
This section analyzes the lag, which is by how much the exchange's
|
|
database reporting is behind in providing us with information about
|
|
deposit confirmations. Merchants probabilisitcally report deposit
|
|
confirmations to the auditor directly, so if the exchange is slow at
|
|
synchronizing its database with the auditor, some deposit
|
|
confirmations may be known at the auditor only directly. However, any
|
|
delta not accounted for by database synchronization delays is an
|
|
indicator of a malicious exchange (or online singing key compromise)
|
|
and should be answered by revoking the exchange's online siging keys.
|
|
% FIXME: reference PhD thesis?
|
|
|
|
The total amount the exchange currently lags behind is
|
|
{\bf {{ data.missing_deposit_confirmation_total }} } or
|
|
{\bf {{ data.missing_deposit_confirmation_count }} } deposit confirmations.
|
|
|
|
Note that some lag is perfectly normal.
|
|
Below, we report {\em all} deposit confirmations that are lagging behind.

\section{Major irregularities}
|
|
|
|
This section describes the possible major irregularities that the
|
|
auditor has checked, and lists all of the actual irregularities
|
|
encountered in detail.
|
|
|
|
\subsection{Emergencies}
|
|
|
|
Emergencies are errors where more coins were deposited than the
|
|
exchange remembers issuing. This usually means that the private keys
|
|
of the exchange were compromised (stolen or factored) and subsequently
|
|
used to sign coins off the books. If this happens, all coins of the
|
|
respective denomination that the exchange has redeemed so far may have
|
|
been created by the attacker, and the exchange would have to refund
|
|
all of the outstanding coins from ordinary users. Thus, the {\bf risk
|
|
exposure} is the amount of coins in circulation for a particular
|
|
denominatin and the maximum loss for the exchange from this type of
|
|
compromise.
|
|
|
|
{% if data.emergencies|length() == 0 %}

\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).
|
|
|
|
{% if data.amount_arithmetic_inconsistencies|length() == 0 %}

{\bf No arithmetic problems detected.}

\subsection{Reserve withdrawals exceeding balance}
|
|
|
|
This section highlights cases where more coins were withdrawn from a
|
|
reserve than the reserve contained funding for. This is a serious
|
|
compromise resulting in proportional financial losses to the exchange.
|
|
|
|
|
|

\subsection{Claimed outgoing wire transfer inconsistencies}
|
|
|
|
This section is about the exchange's database containing a
|
|
justification to make an outgoing wire transfer for an aggregated
|
|
amount for various deposits. It is reported as an inconsistency if the
|
|
amount claimed for the wire transfer does not match up the deposits
|
|
aggregated. This is about a {\em claimed} outgoing wire transfer as
|
|
violations do not imply that the wire transfer was actually made (as
|
|
that is a separate check). Note that not making the wire transfer
|
|
would be reported separately in Section~\ref{sec:wire_check_out}.
|
|
|
|
|
|
{% if data.wire_out_inconsistencies|length() == 0 %}

\subsection{Coin history inconsistencies}
|
|
|
|
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.
|
|

{% if data.coin_inconsistencies|length() == 0 %}

\subsection{Operations with bad signatures}
|
|
|
|
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.
