The counterparty risk is a silent risk that influences the management of money. Banks are not only concerned with changes in prices, but also with the failure to deliver on their part by other parties. The design of Dusk allows trades to be free to settle under their terms without bringing the disclosures to the public.
Uncertainty reduces when obligations are fulfilled on the blockchain using a high degree of security. There is no longer a need to use middlemen to reconcile trades in a slow and unclear way. They are also in a position to maintain changes in trade secrets. The balance is essential since it is impossible to have banks functioning when all the details are transparent. Dusk allows them to minimize risk at a low profile.
The best thing about this is that it is compatible with current financial logic. Clearance and settlement already tend to reduce counterparty risk. Dusk merely replaces faith in intermediaries by effective implementation. I believe this is when blockchain can really be a superior structure to the legacy systems, and not simply an alternative one.
