Creare soldi dal nulla

Convegno

Scienza dietro le quinte
IV Ciclo di conferenze, Primavera 2014

Ti ricordi euro, dollaro, sterlina? Roba del passato. La moneta del futuro si chiama bitcoin ed è interamente basata sulla crittografia. Spedire i tuoi soldi costa pochissimo e per rubarteli i ladri devono risolvere un difficile problema matematico. Chiunque può creare bitcoin dal nulla purché sia in grado di risolvere un problema matematico ancora più difficile. Il volume degli scambi e compravendite in bitcoin raddoppia ogni mese, tanto da costringere le Banche Centrali ad occuparsi del fenomeno.
