[All CBSA Questions]

How does a client app communicate with Hyperledger fabric chaincode (Smart Contracts)?

AThe app uses an SDK which invokes functionality on the chaincode which then announces the transaction to any peers required to endorse the transaction

BThe app uses Hyperledger Composer to communicate with CouchDB which in turn invokes chaincode functionality

CClient apps don't communicate with Hyperledger fabric directly, they must use Hyperledger Composer for the transmission

DThe app points to a node's IP address, then calls an invoke function on the chaincode address to start the write process

I bet the correct answer involves some kind of secret handshake and interpretive dance. Blockchain is all about the theatrics, right?

Wait, so I can't just use my trusty command line and curl to talk to the chaincode? Darn, I was hoping for some old-school hacking action.

Option C is definitely not correct. Client apps can communicate with Hyperledger Fabric directly without needing Composer as an intermediary.

Option B with Hyperledger Composer is an interesting approach, but I'm not sure if it's the only way to communicate with chaincode.

I think Option D is a bit too simplistic. Hyperledger Fabric has more complexity than just pointing to an IP address and calling a function.

User 2: Janine, you're right. Option A explains it better. The app uses an SDK to invoke functionality on the chaincode and announce the transaction to the required peers.

Interesting point, Oretha. I can see how that could also be a valid approach. It's important to understand all the options.

Option A seems like the correct way to interact with Hyperledger Fabric chaincode. Using an SDK to invoke chaincode functions makes sense.

I disagree, I believe the answer is D. The app directly calls the chaincode address to initiate the write process.

I think the answer is A, because the app uses an SDK to interact with the chaincode and notify the necessary peers.
