# Privacy/commercial sensitivity

In discussions with accountants (who have been identified as potential network conveners/administrators) they expressed concerns that their clients may not wish their transaction histories to be visible to all other club participants. One the one hand, calculating [Club 'health'](/0Pyj0CjtSP65hYzq0AdTQQ) metrics may require knowledge of all trades or derived aggregate quantities, but on the other it would be nice if any member who wished could perform their own analyses. Some possible solutions:

* Only a single trusted party (in this case the accountant) has access to all data and does the calculation on behalf of the club;
* Members all publish only their total internal credit spend ($T_{M_{i_{in}}}$ in the notation system described [here](/2iRH2t-QRLOYL3cHkbCgTw)), which combined with the total that leaves via the intertrade account (which presumably will be visible to all members) allows anyone to calculate at least some metrics, such as $F$ (see [circularity of trade](/CMlnVwUjR6-EPA4jHyqsqw)).
