Query: Augmenting Fiat Currency with an Integrated Managed Cryptocurrency   In this work, we investigate how the governance features of a managed
currency (e.g., a fiat currency) can be built into a cryptocurrency in order to
leverage potential benefits found in the use of blockchain technology and smart
contracts. The resulting managed cryptocurrency can increase transparency and
integrity, while potentially enabling the emergence of novel monetary
instruments. It has similarities to cash in that it enables the general public
to immediately transfer funds to a recipient without intermediary systems being
involved. However, our system is account-based, unlike circulating bank notes
that are self-contained. Our design would allow one to satisfy know your
customer laws and be subject to law enforcement actions following legal due
process (e.g., account freezing and fund seizure), while mitigating
counterparty risk with checks and balances. Funds can thus be transferred only
between approved and authenticated users. Our system has on-chain governance
capabilities using smart contracts deployed on a dedicated, permissioned
blockchain that has different sets of control mechanisms for who can read data,
write data, and publish blocks. To enable the governance features, only
authorized identity proofed entities can submit transactions. To enable
privacy, only the block publishers can read the blockchain; the publishers
maintain dedicated nodes that provide access controlled partial visibility of
the blockchain data. Being permissioned, we can use a simple consensus protocol
with no transaction fees. A separate security layer prevents denial of service
and a balance of power mechanism prevents any small group of entities from
having undue control. While permissioned, we ensure that no one entity controls
the blockchain data or block publishing capability through a voting system with
publicly visible election outcomes.
