Answers

D.
R3 Corda is a proof of work based blockchain
Answers
D.
R3 Corda is a proof of work based blockchain
Suggested answer: A

Explanation:

Corda does not share the same requirements as Bitcoin: we require absolute certainty over transaction finality and we need to know who our counterparts are. So we had the freedom - and took this opportunity - to solve the consensus problem in a different way. In particular, Corda solves the privacy issue in a number of manners, primarily by allowing for separation of consensus into a service which we call the Notary Cluster. Corda was designed for business from the start. It has no cryptocurrency built into the platform and does not require mining-style consensus, which imposes great cost with little business benefit.
