As the global economy gets increasingly more interconnected and financial instruments get more complex, settlement time can mean the difference between profit and loss. The current banking system is ill-equipped to guarantee settlement time on most transactions. Moreover, transaction reversibility adds uncertainty to the mix (take for example the dynamics between high-frequency trading and private exchanges).
In the Public Mint network, transactions are irrevocable and immediately settled after one block confirmation, ensuring predictability. This enables high-throughput, time-sensitive business models operating at low margins, and with much more precision than via banking systems.
