Discuss Blockchain CBSA Exam Topic 4 Question 4

Your company working for is now considering the blockchain. They would like to perform a POC with R3 Cord

a. The CIO was reading about different blockchain consensus algos and would like to understand what type of consensus algos is used with Corda.

What is the best answer?

AR3 Corda is a pluggable blockchain and allows the enterprise flexibility

BR3 Corda is a byzantine fault tolerant blokchain

CR3 Corda is a proof of stake based blockchain

DR3 Corda is a proof of work based blockchain

Suggested Answer: A

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.

Wait, is Corda really proof of work? That sounds off.

Proof of stake? Nah, that's not right for Corda.

Hmm, I'm a bit unsure about this one. I know there are different ways to validate YAML files, but I'm not sure which of these options is the correct one. I'll have to think it through carefully.

This seems straightforward enough. I'd go with option C and implement the logic in a helper class. That way, I can reuse the same code in both the Apex trigger and the Visualforce controller. Keeps things DRY and maintainable.

I'm pretty confident I know the answer to this one. The ping tool is used to test network connectivity and determine if a host is reachable, so I'll select options B and C.

I think option A about cost savings is a strong candidate because outsourcing often leads to lower expenses.

Okay, let me think this through step-by-step. First, I'll need to identify the nature of each accounting change and how it impacts the retained earnings balance. Then I can calculate the net effect and select the appropriate answer choice.
