Question 1

Which tool is commonly used to generate cryptographic material (certificates and keys) for a Hyperledger Fabric network?

Accepted Answer

cryptogen

Answer

The `cryptogen` tool is the standard Fabric utility for generating all required cryptographic material based on a network topology defined in a crypto-config.yaml file.

Question 2

What is the key difference between a local MSP and a channel MSP in Hyperledger Fabric?

Accepted Answer

Local MSP defines identity at the node level, while channel MSP defines membership rules for a specific channel

Answer

A local MSP defines the identity and permissions of a specific node or user, while a channel MSP defines the rules for validating identities that can participate in a given channel.

Question 3

What does CRL stand for in Hyperledger Fabric identity management?

Accepted Answer

Certificate Revocation List

Answer

CRL stands for Certificate Revocation List, which identifies certificates that have been revoked and should no longer be trusted within the Fabric network.

Question 4

What is the purpose of the `signcerts` folder within an MSP directory structure?

Accepted Answer

To store the entity's own signing certificate used for identity

Answer

The `signcerts` folder in an MSP directory contains the entity's own X.509 certificate used for signing transactions and proposals.

Question 5

What is the role of the `admincerts` folder in a Hyperledger Fabric MSP?

Accepted Answer

It contains certificates of identities with administrative privileges for the organization

Answer

The `admincerts` folder contains certificates of identities granted administrative privileges, allowing them to perform admin operations like instantiating chaincode on channels.
