Are you preparing for the Hyperledger fabric interview session? A Blockchain platform has extended in its demand from the last couple of years. The world’s biggest organizations like Microsoft and Facebook are looking for a Certified Hyperledger Developer. Hyperledger is an open-source blockchain solution that aims to enhance through global participation.

Here we will discuss the most significant Hyperledger fabric questions along with their answers.

Question 1: What is Hyperledger fabric?

Hyperledger fabric is a distributed ledger platform. It is a favourable Hyperledger project. This technology is based on smart contract and ledger solutions. Its versatile and commutable design assures a wide range of use cases.

A Blockchain hyperledger certification is designed to present in depth understanding of Hyperledger blockchain solutions.

Question 2: Does Hyperledger fabric provide smart contracts?
Yes, Hyperledger provides smart contact and this feature is known as Chaincode. It is one of the key design features of Hyperledger fabric architecture.

Question 3: Can subnet transactions ...
... be noticeable to the public?
No, they are not visible to the public members.

Question 4: Define Hyperledger Burrow?
Hyperledger Burrow is based on a permissioned smart contract blockchain solution. It is supported by Linux and Intel premises. It implements Ethereum program on virtual machines based on permissioned platforms.

Question 5: What is Hyperledger Iroha?
Hyperledger Iroha is a software that is based on a distributed ledger platform that works well with infrastructure and IoT models.

Question 6: What are the stages of the Hyperledger cycle?

There are five phases of the Hyperledger model cycle.
• Project Proposal
• Project Incubation phase
• Project set to active stage
• First main release of a project
• Deprecated stage of a project
• End phase of project

Question 7: What are the benefits of Hyperledger Fabric?

There are several advantages of Hyperledger fabric projects.
• Modular architecture
• Permissioned platform
• Chaincode feature
• Scalability
• Rich queries
• High performance

Question 8: Define Hyperledger Avalon?

It is a tool based on independent ledger technology. It uses trusted computational specification for its implementation.

Question 9: Define Hyperledger Transact?

It is a library which is used to reduce the writing process of distributed ledger platforms. It offers the capability to develop standard interface.

Question 10: What is YAML?

YAML is a file that is used in the Hyperledger model. It is a human understandable language based on data serialization. This language is used to arrange several outlooks of the Hyperledger project.

Question 11: What are the components of Hyperledger fabric?
Hyperledger fabric has two components.
• Transactions log
• State data

Question 12: Define Channel?

The subnet of Hyperledger blockchain is called a channel. You can have an infinite number of blockchain channels.

Question 13: Define consensus mechanism?
It is used to validate the activities of transitions within the blockchain. Hyperledger project utilizes Practical Byzantine Fault Tolerance also known as PBFT.

Question 14: Define Hyperledger Quilt?

It is a java implementation based on interledger protocol. It is used to authorize crypto across any payment systems.

Question 15: Define Hyperledger Indy?

Hyperledger Indy is based on distributed software that provides renewable libraries, tools and components for digital assets on blockchain networks.

Question 16: What are the key design features of Hyperledger fabric architecture?

There are six design features of the Hyperledger fabric model.
• Privacy
• Assets
• Chaincode
• Membership and Security features
• Ledger features
• Consensus algorithm

Question 17: What is BaaS?

The full form of BaaS is Blockchain as a Service. The topmost superiors in this sector are Microsoft, Amazon, Google and IBM. This is the best method for organizations to host their application on the operational blockchain.

Question 18: Define Hyperledger Sawtooth?

Hyperledger Sawtooth is a software that is based on distributed ledger technology. It provides flexible and modular architecture design similar to fabric.

Question 19: What is Hyperledger Besu?

Hyperledger Besu is a business ready Ethereum client. It can be both a public and private permissioned platform.

Question 20: Define Golang?

Golang is a name of a coded language that is used in Hyperledger fabric models. It has a high level of efficiency with static typing. It has an embedded testing environment. Chaincode feature of Hyperledger fabric is written using the Golang language.

Question 21: Which programming languages are favourable to implement chaincode?

Java and Golang languages are used to write chaincode.

Question 22: Define Identity management?

It is an embedded service that is used to maintain security, digital assets, roles and members of accounts.

Question 23: What are nodes in Hyperledger?
The transmission units of Hyperledger are known as nodes. Each node has its own purpose.

Question 24: What are the categories of nodes?

There are three different categories of nodes.
• Client Node - This node starts the process of transactions
• Peer Node - The second node performs the process of transactions
• Order Node - The third node promises the dispatch.

Question 25: Can the second node be a part of many channels?
Yes.
