Which is the last step in the Hyperledger Fabric transaction flow?

AEndorsing and Ordering

BCommitment and notification

CLedger updated and commitment

DEndorsing and notification

Suggested Answer: B

The last step in the Hyperledger Fabric transaction flow is the commitment of the transaction to the ledger and the subsequent notification to the client application1. Once the transaction has been endorsed and ordered, it is committed to the ledger on all peers. After the transaction is committed, the peers asynchronously notify the client application of the success or failure of the transaction.This ensures that the client application is aware of the outcome and can take appropriate actions based on the result of the transaction1

Just to clarify, the transaction flow ends with the ledger update.

Wait, are we sure about that? Seems like it could be B too.

I agree with Isreal, C is the correct answer!

I think it's B, commitment and notification.

The last step is definitely C, ledger updated and commitment.

I’m leaning towards "Commitment and notification" since it seems to fit the end of the process, but I could be mixing it up with another topic.

I feel like "Endorsing and Ordering" was mentioned a lot in our study materials, but I can't recall if it's the final step.

Erasmo 1 year ago

I remember practicing a question about the transaction flow, and I think it ended with the ledger being updated.

Mica 1 year ago

I think the last step might be related to commitment and notification, but I'm not entirely sure.

I'm a bit confused on the difference between "Ledger updated and commitment" and "Commitment and notification". They both sound like the final step, but I'm not sure which one is correct. I'll have to review my notes to be sure.

Okay, let me walk through this step-by-step. First, the transaction proposal is endorsed by the relevant peers. Then it's ordered and packaged into a block. Finally, the block is committed to the ledger and the client is notified. I think the answer is B, Commitment and notification.

Hmm, I'm a bit unsure on this one. I know the transaction flow involves endorsing, ordering, and committing, but I can't quite remember the exact order. I'll have to think this through carefully.

I'm pretty confident that the last step is Commitment and notification, since that's when the transaction is officially recorded on the ledger and the client is notified.

Hmm, I'm a bit unsure about this one. The exhibit doesn't provide much context, and the question is asking about a specific configuration change. I'll need to think this through carefully.

I've got this! The question is asking about the specific ownership level that would make ST an associate investment. I just need to carefully evaluate each option.

I'm not entirely sure what a pipeline lookup transformation is, but I'll try to think it through. Maybe it has something to do with using a pipeline to create a lookup cache that's split across multiple partitions?

I agree with it seems like the most logical final step in the transaction flow.
