\subsection{Emergencies}
|
|
|
|
|
2017-11-06 00:03:08 +01:00
|
|
|
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.
