After the matching TradeOffers have been received, the results are

distributed to the participants in the trade. In order to distribute
the results of a trade, TradeOffer documents are used. Two
distinctive characteristics of result TradeOffers is the inclusion of
a statusText element that indicates the TradeOffer that originated
this message, and the correspondence of the included asset with the
requestedInstrument information instead of the offeredAsset. In the
first result TradeOffer returned to Trader A, the statusText is
"filledOrder - e1abb079894aac7a0fd706ef43cb7c35d7e4094f", which
provides the hex-encoded SHA-1[4] digest value of the original
TradeOffer.

3. Security Considerations
The participants in an information currency transaction should take
care to ensure that their transaction messages are encrypted. This
is because an attacker intercepting the information currency
exchanged by particpants can potentially steal the economic value of
the information currency by exchanging the intercepted information
currency to obtain exclusive ownership for themselves.
