1- What Is Hyperledger Fabric ?

• It is an open source platform started by Linux
  Foundation in 2015. It was started to provide
  enterprise solution to the companies. It provides
  a podium for developing applications on modular
  architecture. Hyperledger promotes cross-industry
  collaborations by using DLT frameworks, access
  control, smart contracts, GUI, client libraries.

4

• What are the Nodes?
• The communication entities in Hyperledger are
  called Nodes.
• What are the three different types of Nodes?
• The following types of nodes exist in the system
  

5

• Client Node- the one that starts the transactions
• Peer Node- It commits the transactions
• Order Node- It guarantees the delivery

6

• What is Channel?
• In Hyperledger, the channel is the subnet of the
  main Blockchain. There can be a number of
  channels.
• Can different channels have a peer or node?
• Yes, it can be a part of different channels.

7

• If a transaction takes place in the subnet, is it
  visible to the public?
• No, the transactions are only visible to the
  subscribers of the particular channel.
• What Consensus Mechanism?
• When we talk in context of Hyperledger, then
  every node represents a client. It makes use of
  Practical Byzantine Fault Tolerance or PBFT
  model.

8

• What is HyperLedger SawTooth Lake?
• This is an open-source project supported by
  Intel.
• Hyperledger Indy What do you know about it?
• It is an open-source project that supports
  independent identity on Blockchain and DLT. This
  platform provides tools, reusable components,
  libraries for providing digital identities.

9

• Tell me something about Hyperledger Burrow?
• Hyperledger Burrow executes Ethereum smart
  contract code on a permissioned virtual machine.
  This is sponsored by Linux and Intel. It provides
  transaction finality on a proof-of-stake PBFT
  based consensus engine.
