[All HFCP Questions]

Which are the transaction steps that are managed by the Fabric gateway service?

AFinding a nonce for a pre-image of a hash function for mining.

BCollect transactions into a block and eliminating invalid transactions.

CEvaluate, endorse, submit, and get commit status.

DRealizing a distributed verifiable random function for leader election.

Show Suggested Answer

Suggested Answer: C

The transaction steps managed by the Fabric gateway service in Hyperledger Fabric are to evaluate, endorse, submit, and obtain the commit status of transactions. This service simplifies the process for clients by handling these critical transaction steps, which facilitates more efficient transaction processing and management within the network .

I thought D was a thing in other protocols, not Fabric.

Wait, A is about mining? That’s not what Fabric does!

B sounds important too, but not the main steps.

I’m confused about the nonce and mining part in option A; I thought that was more related to proof-of-work systems, not Fabric.

I’m pretty certain that the gateway service handles the evaluation and endorsement of transactions, so I would lean towards option C.

I remember practicing a question about transaction steps, and I feel like option C sounds familiar, but I can't recall the details.

I think the Fabric gateway service is mainly about evaluating and endorsing transactions, but I'm not entirely sure if that's all it does.

Okay, let me think this through. The Fabric gateway service is responsible for the client-side interactions with the blockchain network, so I'm guessing the answer has to do with evaluating, endorsing, submitting, and getting the commit status of transactions.

Hmm, I'm a bit unsure about this one. The options seem to cover different aspects of blockchain technology, but I'm not sure which ones specifically relate to the Fabric gateway service.

This question seems pretty straightforward. I'm pretty confident I can identify the transaction steps managed by the Fabric gateway service.

I think the key here is to focus on the Fabric gateway service specifically, rather than general blockchain concepts. The options about mining, block creation, and distributed random functions don't seem directly relevant to the Fabric gateway's responsibilities.

This looks like a good solution to me. Transparent Data Encryption with customer-managed keys should provide the level of encryption and key rotation needed. I'll make sure to highlight the key details in my answer.

Okay, let me break this down step-by-step. I need to find the expected value for each project, then compare them to see which one has the lowest risk.
