Solidus is a cryptocurrency ("blockchain") that can be run by a confederation or consortium of trustworthy entities-- -banks, governments, auditors, etc. While it retains some of the benefits of decentralization, Solidus offers higher performance and tighter governance and control than existing cryptocurrencies such as Bitcoin. Many successful peer-to- peer technologies have historically been eclipsed or supplanted by centralized or commercial systems (e.g., in the online music industry). Solidus addresses the possibility and desire by many financial institutions that cryptocurrencies and contracts will follow a similar path.
