DTo validate transactions and maintain the blockchain ledqer

Show Suggested Answer

Suggested Answer: D

In Hyperledger Fabric, if a user submits a transaction with no matching function specified in the smart contract, the unknownTransaction function is invoked by default. This function serves as a catch-all method that can be used to handle cases where the transaction type is not recognized, providing a mechanism to manage or log these occurrences effectively .

I'm a bit confused; I thought the ordering service also had a role in validating transactions, but maybe that's more for the peers?

I remember something about it managing identities too, but that might be more related to the membership service provider.

I think the ordering service is mainly about assembling transactions into blocks, but I'm not entirely sure if that's its only role.

I think the ordering service is responsible for the overall ordering and consensus of the transactions in the network. It's not about endorsing or validating transactions directly, so I'll rule out options A and D. I'll go with C as the best answer.

The ordering service is the key to the Hyperledger Fabric model. Its job is to assemble transactions into blocks and maintain the blockchain ledger. That's the most important function, so I'll select option C.

Haha, yeah, the ordering service is the bouncer of the Hyperledger Fabric party. It's gotta let the right transactions in and keep the troublemakers out. I'd say C is the winner here.

Oh, I got it! The ordering service is like the traffic cop of the Hyperledger Fabric network, making sure the transactions get to the right place. C is the way to go!
