This is usually either the exchange's aggregator, the bank's wire transfer logic, or the synchronization of databases between exchange and auditor. Significant lag may be indicative of fraud, while moderate lag is indicative that the systems may be too slow to handle the load. Small amounts of lag can occur in normal operation. \subsection{Deposit lag} The total amount the exchange currently lags behind in deposits 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. % Table generation tested by testcase #1 in test-auditor.sh {% if wire.lag_details|length() == 0 %} {\bf No non-tiny wire transfers that are lagging behind detected.} {% else %} \begin{longtable}{l|r|r|c} {\bf Deadline} & {\bf Amount} & {\bf Row} & {\bf Claimed done} \\ \multicolumn{4}{l}{\bf Coin} \\ \multicolumn{4}{l}{\bf Target account} \\ \hline \hline \endfirsthead {\bf Deadline} & {\bf Amount} & {\bf Row} & {\bf Claimed done} \\ \multicolumn{4}{l}{\bf Coin} \\ \multicolumn{4}{l}{\bf Target account} \\ \hline \hline \endhead \hline \hline {\bf Deadline} & {\bf Amount} & {\bf Row} & {\bf Claimed done} \\ \multicolumn{4}{l}{\bf Coin} \\ \multicolumn{4}{l}{\bf Target account} \\ \endfoot \hline \hline {\bf Deadline} & {\bf Amount} & {\bf Row} & {\bf Claimed done} \\ \multicolumn{4}{l}{\bf Coin} \\ \multicolumn{4}{l}{\bf Target account} \\ \caption{Lagging non-tiny transactions.} \label{table:lag} \endlastfoot {% for item in wire.lag_details %} {{ item.deadline }} & {{ item.amount }} & {{ item.row }} & {% if 'claimed_done' in item %} {{ item.claimed_done }} {% else %} N/A {% endif %} \\ \nopagebreak \multicolumn{4}{l}{ {\tt \small {{ item.coin_pub }} } } \\ \nopagebreak \multicolumn{4}{l}{ {\tt {% if 'payto_uri' in item.account %} {{ item.account.payto_uri }} {% endif %} } } \\ \hline {% endfor %} \end{longtable} {% endif %} \subsection{Reserve closure lag} The total amount the exchange currently lags behind in reserve closures is {\bf {{ wire.total_closure_amount_lag }}}.

Merchants probabilistically 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 signing key compromise) and should be answered by revoking the exchange's online signing keys. % TODO: maybe reference PhD thesis on this? The total amount the exchange currently lags behind is {\bf {{ deposits.missing_deposit_confirmation_total }} } from a total number of {\bf {{ deposits.missing_deposit_confirmation_count }} } deposit confirmations.

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 denomination and the maximum loss for the exchange from this type of compromise. {% if (coins.emergencies|length() != 0) %} The total risk from emergencies detected by amount is {\bf {{ coins.emergencies_risk_by_amount }} }.

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). Note that the deltas only sum up the issues where $P \not= 0$ as only then we can tell if the problem lead to a profit or loss. The {\bf P} column is set to "1" if the arithmetic problem was be determined to be profitable for the exchange, "-1" if the problem resulted in a net loss for the exchange, and "0" if this is unclear or at least the gain/loss is not easily determined from the amounts and thus not included in the totals. \subsubsection{For aggregation} % Table generation tested by testcase #XX in test-auditor.sh {% if aggregation.amount_arithmetic_inconsistencies|length() == 0 %} {\bf No arithmetic problems detected.} {% else %} \begin{longtable}{p{3.5cm}|r|r|r|c} {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \hline \hline \endfirsthead {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \hline \hline \endhead \hline \hline {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \endfoot \hline \hline \multicolumn{2}{l|}{ {\bf $\sum$ Deltas (Auditor-Exchange)} } & + {{ aggregation.total_arithmetic_delta_plus }} & - {{ aggregation.total_arithmetic_delta_minus }} & \\ \caption{Arithmetic inconsistencies.} \label{table:amount:arithmetic:inconsistencies:aggregation} \endlastfoot {% for item in aggregation.amount_arithmetic_inconsistencies %} \truncate{3.3cm}{ {\tiny {{ item.operation }} } } & {{ item.rowid }} & {{ item.exchange }} & {{ item.auditor }} & {{ item.profitable }} \\ \hline {% endfor %} \end{longtable} {% endif %} \subsubsection{For coins} % Table generation tested by testcase #18 in test-auditor.sh % Table generation tested by testcase #3 in test-revocation.sh {% if coins.amount_arithmetic_inconsistencies|length() == 0 %} {\bf No arithmetic problems detected.} {% else %} \begin{longtable}{p{3.5cm}|r|r|r|c} {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \hline \hline \endfirsthead {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \hline \hline \endhead \hline \hline {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \endfoot \hline \hline \multicolumn{2}{l|}{ {\bf $\sum$ Deltas (Auditor-Exchange)} } & + {{ coins.total_arithmetic_delta_plus }} & - {{ coins.total_arithmetic_delta_minus }} & \\ \caption{Arithmetic inconsistencies.} \label{table:amount:arithmetic:inconsistencies:coins} \endlastfoot {% for item in coins.amount_arithmetic_inconsistencies %} \truncate{3.3cm}{ {\tiny {{ item.operation }} } } & {{ item.rowid }} & {{ item.exchange }} & {{ item.auditor }} & {{ item.profitable }} \\ \hline {% endfor %} \end{longtable} {% endif %} \subsubsection{For reserves} % Table generation tested by testcase #2 in test-auditor.sh {% if reserves.amount_arithmetic_inconsistencies|length() == 0 %} {\bf No arithmetic problems detected.} {% else %} \begin{longtable}{p{3.5cm}|r|r|r|c} {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \hline \hline \endfirsthead {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \hline \hline \endhead \hline \hline {\bf Operation} & {\bf Row} & {\bf Exchange} & {\bf Auditor} & {\bf P} \\ \endfoot \hline \hline \multicolumn{2}{l|}{ {\bf $\sum$ Deltas (Auditor-Exchange)} } & + {{ reserves.total_arithmetic_delta_plus }} & - {{ reserves.total_arithmetic_delta_minus }} & \\ \caption{Arithmetic inconsistencies.} \label{table:amount:arithmetic:inconsistencies:reserves} \endlastfoot {% for item in reserves.amount_arithmetic_inconsistencies %} \truncate{3.3cm}{ {\tiny {{ item.operation }} } } & {{ item.rowid }} & {{ item.exchange }} & {{ item.auditor }} & {{ item.profitable }} \\ \hline {% endfor %} \end{longtable} {% endif %} \subsection{Reserve withdrawals exceeding balance} This section highlights cases where more coins were withdrawn from a reserve than the reserve contained funding for.
